No, I was thinking about differences in ground potential between the two buildings, static electricity, lightning strikes, that sort of thing.

(Ie: I connected the "telco" socket on the modem to the phone line from the wall, and then the telephone into "telset" on the modem.

old modems & a packet switcher

by yakowenk＠cs.unc.edu

Okay, I've now given up hope that those old modems will ever be at all useful or interesting to me. So they're up for grabs, for the cost of postage. There are two BellSouth 212A's, and two similar modems by Penril. None respond to the Hayes "AT" command set, and each has a handful of pushbutton switches on the front, as per my previous post. Power supplies are all internal; they each have an ordinary 120v line cord. The consensus seems to be that they need some associated equipment to do the dialing. Because of this, I have no idea if they work or not. They are each maybe 1' x 1' x 2", but not very heavy. (That size is an estimate from memory, and might be off by a bit). I doubt they are useful in any modern setup, but they might be regarded as classics. If nobody here wants them, they return to the dumpster from which they came. My apartment now has negative space available, if you know what I mean. Similarly, I've got a Sytek 2532 Packet Communications Unit, with about half a dozen boards in it. This is a rack-mount beastie, and weighs like it, so it could be expensive to ship. Still, if you want it, or any of the boards from it, let me know. Like the modems, I have no way to test it, and no idea whether or not it works. But I'd be thrilled to get it out of the trunk of my car. :-) And maybe this is a good time to mention my "for trade" web page, containing a list of compu-junk that needs a good home. It is at this URL: http://www.cs.unc.edu/~yakowenk/classiccmp/fortrade.html Cheers, Bill.

CBM B500

by franke＠sbs.de

Since I rediscovered a B500 in my junk some weeks ago, I'm searching for information. Until now i could trace nothing in the web or any magazine from that time. The Computer in question is a Commodore B500, Basicly a CBM II LP. I am not talking about the P500. The mobo is technicaly the same than the CBM 610 (B128) but a different layout (only some lines) and a (lower) part#. Also the Version/Part#'s of the kernal/basic EPROMS are lower than any known (to me) B128/B256/6x0/7x0 type. The mobo and all chips are dated to 1982 - again way before any other CBM II I know. AFAIR the CBM II line was introducted in 1983. Any Info would be usefull. Gruss H. -- Ich denke, also bin ich, also gut HRK

DEC TU-58 Drives

by healyzh＠ix.netcom.com

I finally got back to working on my PDP-11/44, and finished cleaning it up yesterday. So now I'm ready to start testing stuff. Which brings me to my question, I went ahead and plugged the TU-58 drives in to see if they would give any indication of life. Not a thing. Do they have to be plugged into the line (serial I think), or have a tape in them before they will show any signs of life? Zane | Zane H.

Zenith time manager software FS

by rhblake＠bbtel.com

I have an unused and unregistered copy, complete, of Zenith Data Systems/Heath Company's "Breakthrough Timeline" which appears to be a timeline creator/project manager. It has the original box, manuals, key template, registration certificate and the original 5.25" 360k floppies (still in the envelope). From scanning the manual it's roughly 1986/87 vintage and should run on most any machine from 8086/8088 up through our present array of hardware. Really good condition visually too, might be good as part of a collection. Need $12 for it which includes mailing in the 48 CONUS states. First come, first serve.

Maybe off-topic: low/no cost Soft-ICE for x86

by rcini＠email.msn.com

Hello, all: Another crazy project... While working on my old-DOS decompilation project, I've found that it would be handy to have some sort of ICE hardware/software to watch the boot-up sequence, examine specific registers, test code fragments, etc., without crashing my PeeCee. I've been using Debug and testing code fragments to watch changes in the registers. Can anyone point me to a GNU/shareware software-based ICE program, much like NuMega's Soft-ICE Windows, that can do this for DOS? Is it even possible to use a software-based ICE in this instance (because it's before DOS boots). How about this...how about a virtual PC running under OS/2 or Windows NT? It would have to be re-bootable (without crashing the host operating system) and support hot-key break-to-debugger. Sort of like a cross between the vMac Macintosh emulator and WDEB386 (the Windows Kernel debugger). It would be odd to emulate an 8088 on a Pentium 233MMX...hmmm...sounds like a project. Any thoughts??? Rich Cini/WUGNET <nospam_rcini(a)msn.com> - ClubWin/CW6 - MCP Windows 95/Windows Networking - Preserver of "classic" computers <<<< ========== reply separator ========== >>>>>

New Finds

by buck_c＠polygon.com

So I've captured a few new machines - now all I have to do is figure out what to do with them. 1. Fortune 32/16 - System, seperate SCSI tape drive, no HD. No software. Help! 2. 7 (count 'em, 7) Wang systems. I'll have model numbers &such tomorrow (something along the lines of PC-02). Only three monitors, only one keyboard. Two 5 1/4 flopies per, no software. Any help would be a start. Most have Network cards of some kind - is this ethernet? Each has two BNC connecters. Almost looks like a daisy-chain system of some kind. -- J.

OT: Alphastation 200 4/233

by healyzh＠ix.netcom.com

I realize this is off topic, but in case anyone is interested www.onsale.com is selling these for $349.00 of course the one I just got came to $386.46 when you add in shipping. They've got a 1.44Mb floppy, 16Mb of RAM, 2Mb video card, 233Mhz processor and some other things. It doesn't sound like they've got a hard drive, keyboard, or mouse, adn there is no monitor. Still I gather it's a fairly good price, and a bunch of people in the DEC newsgroups are picking them up (I gather they still have about 25 to sell). The best part is this model is supposedly able to run OpenVMS (Alpha), WinNT, Linux, and DEC Unix. Now all I've got to do is save up for a copy of OpenVMS for the Alpha :^) On the downside RAM looks to be spendy for these suckers. Zane | Zane H.

Archive board

by lwalker＠mail.interlog.com

A while back there was a thread re an Archive board ID but I've been unable to find it in my archives. It seemed at the time similiar to a card I have. It's an 8 bit card with a 25 pin F port and a 50 pin internal; it's got an FCC ID # EAX6GP-SC400S which I haven't checked yet since most of the time they're useless. Someone had written 102 A in marker pen.The most important chip is one labelled Archive PT and at the bottom 8517A. It has an E-Prom m5l2764k , another 64 pin chip has 4 numbers , the top one is R6511AQ and the bottom one is 8439 (always had trouble identifying chips based on labelling). It has IRQ stencilled jumpers 2-7 and 5 is jumpered. It has DRQ (DMA ?) 1,2,3 , DACK 1,2,-3 with 1 jumpered on 1 and 3(1), another set of 7 jumpers labelled A3-A9. There are 5 LEDs labelled DS1-DS9. There's a couple of other jumpers and the rest is mostly low powered Schotskys. Anyone with any idea on what this is ? ciao larry lwalker(a)interlog.com

Need info: Data I/O Tape Perforator

by jimw＠agora.rdrop.com

Greetings all; Looking for some information on a new find. A Data I/O Tape Perforator. It's an 8 level, desktop paper tape punch with LED data display (one LED for each channel), and apparently a parallel interface of some type, altho the connector looks somewhat similar to an IEEE-488 connector. However looking at the logic board in the thing pretty much rules out a '488 interface. (not nearly enuf smarts on the board) So... I'm seeking some info on this thing, most specifically with regard to the interface. And before you ask, there is no 'model' number shown on the unit. The ID plate on the back just says "tape perforator". Looked at the Data I/O web site, and found nothing (big surprise... not!) So before I break down and call them to find that no one has any clue as to what I'm asking (sarcasm flag) about, I figured I'd try here. Any help? -jim --- jimw(a)agora.rdrop.com The Computer Garage - http://www.rdrop.com/~jimw Computer Garage Fax - (503) 646-0174

Sun-1 Tape Drive Part II

by karlm＠blitzen.canberra.edu.au

Ok, Sorry about the delay, I got busy with work and didn't get around to working on the Sun unti tonight :) I cleaned the heads with some isopropyl alcohol tonight, but to no avail, I still get the dreaded 96A0 error, I'm beginning to suspect the tapes, however it doesn't matter what tape I put in, it gives exactly the same error, so unless all 4 SunOS tapes have had it, it may be the drive. Further to the error codes, a tape with write protect off gives 86A0 error :) Thanks Karl ------------------------------------------------------------------------------ Karl Maftoum Computer Engineering student at the University of Canberra, Australia Email: k.maftoum(a)student.canberra.edu.au

Near disaster and questions on finds

I use the industrial "pallet racking" available from Home Depot. I think that they cost me around $50-60 per set (4 shelves), but they have a claimed capacity of 1500lbs/shelf. The shelf material is MDF (medium-density fiberboard), and is very strong. I feel very secure that these shelves would be standing long after I'm gone.

The experience I've had was in the apartment where I live, where it is best to make stuff as opposed to buying it because it is difficult to fit storebought things as efficiently.

I'm STILL trying to get all the accumulation of 'stuff' moved out of our old house into the newer house. 21 years worth of 'stuff'. Two weekends ago, a work colleague and I spent 4 hours on that Saturday afternoon moving only *part* of my library. That work consisted of two full loads in my wife's Jeep Cherokee and our friend's Ford Ranger SUV. Books and old magazines are really heavy to move up two flights of stairs. I think we got maybe a third of the library moved. We were almost dead after that. Bev and I have been making small trips in the evenings after supper to take the antique radio collection and tools over to the house and we're making a little bit of headway at that. If we had originally hauled _everything_ over in one or two shots, stuff would be piled up in such a manner I could not ever sort and arrange it properly. I guess the lesson learned here for us is to consider what we keep and pass on to someone else stuff we really should not. Another lesson is _don't_ pack it in so danged tight that if we do have to move (or more regrettably, have to pickup after an earthquake or flood) that the moving task is nearly impossible to do. Also, I cannot find stuff that I _know_ I had put away in the pile. I can't believe all the crap I'm dragging out that I squirrelled away over the last two decades. A part of it is actually heading for the dumpster and most of you would certainly agree if you see it. > >I don't recommend this sort of storage arrangement. I don't know where >anything is and couldn't get at it anyway even if I did. But it allows me >to store the massive amounts of computer junk I have until I can find a >suitable space to do it justice. Agreed re: not recommended! I thought we could find a house with more space for my stuff but nothing that was an affordable price came up for us around here. The new place is just a little bit smaller, now I'm having to sort out stuff to sell, swap or otherwise get rid of. As I said before, some of the old computer stuff I need to divest will be mentioned to you folks first. > >What I recommend to Roger is to first, add an extra support to your >shelves, and make sure you are anchoring them properly with drywall >anchors (if you are mounting the shelves to drywall). Then, pack your >laptops and such inside boxes with some foam in between. That way, if >there is another episode, or an earthquake hits and the computers fall, at >least they will be moderately protected from damaging each other when they >hit the floor. You also might want to consider getting some netting to >prevent the boxes from falling in the first place (in an earthquake at >least). I imagine this would cost some bucks but maybe Target has a good >net material cheap in the garden section. Try Home Depot for ideas also. Good suggestions. The other msg in this thread mentioned chicken wire as a netting-type material too. Although we don't have a real earthquake problem in Western NY State we still do feel them once in a while. Tornados and blizzards are the natural problems we have to deal with more often. I do make sure my shelves are tied to a wall, rafters/floor joists above them or simply themselves together in a mutually supportive manner just in case. If a moderately Big One ever occurred out here, we would be in great trouble as the earth deep down is quite solid and even small local quakes would hurt us more. That Madrid Fault in the Midwest is being watched with a wary eye by some earthquake specialists at the Eathquake Center at the University of Buffalo. Jamestown is sitting on the same tectonic plate. We even feel a jiggle from 3.5 quakes that hit 400 or more miles away out east of here. I know what a 3.6 is as I sat in the dinning room of my best friend and her husband's house up in Orinda, California when one hit in August, '87 centered about 10 or 20 miles away. I really hope and pray that you folks on the Left Coast are not hurt by any nasty quakes that occur.

(Fwd) Archive board

by lwalker＠mail.interlog.com

Not sure if this got thru. If it repeats my apologies. A while back there was a thread re an Archive board ID but I've been unable to find it in my archives. It seemed at the time similiar to a card I have. It's an 8 bit card with a 25 pin F port and a 50 pin internal; it's got an FCC ID # EAX6GP-SC400S which I haven't checked yet since most of the time they're useless. Someone had written 102 A in marker pen.The most important chip is one labelled Archive PT and at the bottom 8517A. It has an E-Prom m5l2764k , another 64 pin chip has 4 numbers , the top one is R6511AQ and the bottom one is 8439 (always had trouble identifying chips based on labelling). It has IRQ stencilled jumpers 2-7 and 5 is jumpered. It has DRQ (DMA ?) 1,2,3 , DACK 1,2,-3 with 1 jumpered on 1 and 3(1), another set of 7 jumpers labelled A3-A9. There are 5 LEDs labelled DS1-DS9. There's a couple of other jumpers and the rest is mostly low powered Schotskys. Anyone with any idea on what this is ? ciao larry lwalker(a)interlog.com

IBM PS/2 L40sx

by roblwill＠usaor.net

I don't know if this is worthy of being a Classic Computer, yet (it's 8 yrs old), but here it goes: I have a PS/2 L40 sx laptop. It has 2MB onboard RAM, and a 60 MB HD. I was wondering if anyone had any expansion RAM, or knew where I could get some for a low price. It has "planar sockets". They look like standard 72-pin SIMM sockets, but Non-parity won't work, parity won't work, and not even PS/2 RAM works in it. I guess it needs a special type of RAM that was made by IBM especially for this computer. ANY information is appreciated!!! ThAnX, -- -Jason (roblwill(a)usaor.net) ICQ#-1730318

< better. Plywood is probably not the best shelving material; I don't < know much about this stuff, but wouldn't solid wood be stronger? No. Plywood is laminated wood veneers and has a strength that exceeds solid boards of the same dimension. It also has the advantage of oriented grain for each layer and available with finished surfaces. A cheaper material is OSB, oriented strandboard the high strength upper class cousin of flake board. The idea of glued up (laminated) woods is quite old and has always been used where strength is a primary concern. It can be used to get grain and layers that have differing color as well. Very strong shelves can be made up using 1x3 stock and plywood combined with 2x4 or 2x6 uprights. The problem is good quality wood has gotten expensive. Allison

#%&*! This compaq is cursed! (ot)

by maxeskin＠hotmail.com

OK, this isn't even funny anymore. I replaced the keyboard, and the thing works fine. The problem is that the cable leading to the display was damaged, and the backlight ceased to work. So, I decided to bypass the cable (only one trace). This was fine, but I tried to solder the wire I was using directly to a pin of the surface-mounted ribbon cable connector (the output, that connects to the circuit board inside the display panel). Of course, i bridged four of the pins. I have no desoldering tools of any kind, but I doubt it would help much. The solder got into little crevices between the pins and onto the circuit board itself. I guess this board is non-essential, but is there any way I could un-bridge this stuff? ______________________________________________________ Get Your Private, Free Email at http://www.hotmail.com

Near disaster and questions on finds

Here's how I store my "stuff": I keep my collection in my basement, so I have made shelves out of cement blocks and 2x4's (like the outdoor flower displays at WalMart), and then I put 1/2" plywood on top of the 2x4's and screw it down with drywall screws. If you feel that you need extra strength, you can lay the 2x4's on edge, and then screw the plywood on.

Toshiba T3100/20/Tadny 1400 HD

Hi. I have two WANG WLTC laptops, two Tandy 1400HD's, and I used to have a Toshiba T3100/20 and a T1200. They all had the same type of HD connector. The Tandy's have 20MB ALPS drives, and the WANG's have 10MB JVC drives, and the Toshiba's had 20MB JVC drives. I have NEVER been able to find replacement drives with this same connector.

ZX-81 custom chip - watizit?

Is this chip truly > "custom" or is it a relabeled Z80 support chip? Yes, it is. Or better it is a semi cusom chip - like ASICs today. The Basic design is a standard compilation of TTL functions, only the last metal layer is custom. This was an early attempt by some chip manufacturers to cut design costs - only this last layer had to be designed for every customer. The technic was(is) called ULA Unassigned(?) Logic Array. And thats also the name used by ZX-fans for this Chip. The ULA replaces something like 15 or 20 standard TTL bugs from the ZX-80 design - the 81 is just a ZX-80 II :) Gruss H.

Can anyone give an overview, and would anyone know of a fix? How long was the C64 sitting in the basement? It could be that the key contacts are corroded. It happened to me once on a TRS-80. The key wouldn't type, but if I'd pound on it for a while, it would type, but then keep typing until I pounded it again. I took the keyboard apart, took the cap off of the key, and then cleaned the contacts with alcohol. It worked fine after that. It doesn't sound like it would be bad, since if something was dead, probably the whole top line wouldn't work - or at least more than 4 keys. GooD LucK, -- -Jason (roblwill(a)usaor.net) ICQ#-1730318

Atari Joystick Connector

by jsalzman＠hersheys.com

Digi-Key has them. Part number: A2096-ND Go to http://www.digikey.com and do a Part Search for the above part number. Just make sure the mount spacing between the connector back edge and the solder pins on the Atari port is the same as in the Digi-Key specs. Anything different could cost a lot more for a replacement connector with a non-standard mount spacing. The sample PDF page of the catalog entry is available online. Pictures and details of the part are available there. You need Acrobat reader to view the catalog page. Jeff Salzman >prefer a broken one as ripping up a working machine is just wrong.

Can anyone give an overview, and would anyone know of a fix? Hmm if it is only about this keys, it cant be a dead line. But for C64 it is still about to throw the unit away - (I just hauled 12 C64 from a school today) they are $5 thingis. Or store it as spare part (and they are worth about USD 50 as replacement parts). I wouls sugest a rapair only if it is about a special unti of personal history/interest.

Memory's hazy, but I think it had a custom 15-pin connector at the back, but it threw out standard frequencies that could be used with a Sun workstation monitor... I did find some info on the web for the box, it's possible I have it at home - just give me a shout... As for things using '88k's, My old Tektronix XD88 Unix box also used one as it's main CPU. I think they're supposed to be a lot better chips than 68k's, just that they never really caught on - 68k's were too well established (and therefore a lot cheaper). cheers Jules >

ZX-81 custom chip - watizit?

No, it's a ULA (uncomitted logic array, a sort of early ASIC) made by Ferranti. The ULA replaces several TTL chips that were present in the ZX80. There were two or three revisions of these, and a similar idea was used in the Sinclair Spectrum. The BBC Micro also used Ferranti ULAs, one for the serial controller and one for the video controller. IIRC, the ZX and Spectrum ULAs are still available from CPC in Britain. A ULA consists of lots of simple logic gates laid out in a square array, but the basic design has no final metalisation layer - and hence no interconnections between the gates. A designer using a ULA would translate his circuit diagram into an interconnection diagram for the array, and hand that over to Ferranti, who would then produce the mask for the final stage of the manufacturing process. The end result is a bit like an FPGA, but with simopler building blocks. Apart from that, the relationhip between a ULA and an FPGA is bit like the relationship between a masked ROM and an EPROM. -- Pete Peter Turnbull Dept. of Computer Science University of York

m88k info

by poesie＠geocities.com

I was at a computer junk store the other day and saw a long flat computer case/box; about 3 inches high, about 18 wide and 10 long. It was some sort of unix terminal/system/something, because it still had a label with the network host name etc on it. BUT- it said m88k on it! it might have also said NCR but I'm not sure. what kind of things are used on the 880x0's? I know NetBSD has an m88k port but who or what would have originally run on such things, and how old are they? I have to admit it piqued my curiosity. If possible I'm going back to grab the thing. One last question- how do the 88k's compare to the 68k's or a MIPS chip? I remember some discussion about SGI switching to MIPS instead of using the 88k due to slow development or something to that effect. (whether that's true or not I have no idea, so don't flame me :) -Eric

I agree, this type of shelf he described is great. i worked at a restaurant once that used these shelves and they very adjustable and extremely sturdy. I have seen these racks for sale at housewares stores for somewhat cheaper than if you went to a business/restaurant supply store.

Well, Quakes can be interesting, but really what they mean is your house/office/whatever is going to be better built than elsewhere, and you grow up with an instinctive eye for not putting breakables in precarious places. Besides, I'd rather live somewhere that had occassional earthquakes rather than a regular tornado, hurricane, or blizzard season... 8^) A lot of people suggested stronger shelves, which would be a good idea except that we're talking 7 sets of shelves (plus a whole lot of computers that I keep promising my girlfriend will get put in there) so $50/set is a lot of dough. Does anyone have any experience with overloading the plastic shelves? We have some running around here, but I don't know how strong they are. As for starting what will end up on the floor on the floor, that would be cool too, but I only have so much floor space (The house across the street just went on the market -- 2700 sq ft, 4 bedrooms, yard: $695K, and no, I don't live in a rich neighborhood.) and everybody pisses and moans as it is about the computers strewn throughout the house already. 8^) A lot of people suggested chicken wire or bungees to hold things on the shelves, which prompted me to think of a low-cost solution my GF's sister-in-law came up with: twine. Lace twine around/through the vertical supports. Surplus phone wire or such would work too, I think. --------------------------------------------------------------------- O- Uncle Roger "There is pleasure pure in being mad roger(a)sinasohn.com that none but madmen know."

notebook parts sources

Dead keys on C64

Rare Tandy 1400???

by roblwill＠usaor.net

Hello everyone... I have two Tandy 1400HD laptops. One has an NEC V20 processor in it. The other has an actual Intel 8088 processor. I checked with Tandy's support site, and the 1400 series was shipped from the factory with the V20 chip. The one that I have with an 8088 is also from the factory - it's the original processor. The person who gave it to me was the original owner, and she had never had it serviced. When I took it apart to try to fix the power supply, that's when I noticed that the processor was different. When buying a 1400 new, was it possible to order it with the Intel 8088 chip instead of the NEC V20? Or was some mistake made at the factory (they ran out of V20 chips?) and an Intel chip was put in this one? Does anyone else have a 1400 with an Intel 8088? It this computer possibly worth more than the one with the V20 (I doubt it)? Any information is appreciated. ThAnX, -- -Jason (roblwill(a)usaor.net) ICQ#:1730318

Help! Grid 1535 EXP

by rigdonj＠intellistar.net

I tried removing the hard drive and connecting it to a PC in order to reload everything as Doug sugested. The drive is a Conner CP-3044 (2 heads 1047 cylinders, 42 Mb IDE). MS-DOS chokes on anything over 1024 cylinders so I tried to run it on the PC with the cylinders set at 1024 and 1047 but the system said "Drive 0: initialization failure" every time. Does anyone know what drive geometry the Grid uses? I don't *think* the drive is actually bad since I got past this point with the drive installed in the Grid. Will the Grids boot from the external floppy drive? If so, does anyone have one that I can borrow long enough to reload DOS and FastLynx? Joe

A simple addition is plywood 1fx2f or 1fx4f (rough size) scred inside the angle steel that form the uprights to form a 3 sided box around the shelf, then one of those cargo nets used for pickup trucks in the front. Properly secured this will hold ANYTHING. RE: earthquake zones. Assuming no fire, racks like that or standard equipment racks can support amazing amounts of weight such that if the "roof" should cave there is support to protect the equipment between and in the racks. Also if racks cannot be tied to the wall, then back to back works or in groups of four with a two back to back and one at each end bolted together as one large unit. The idea is to increase the effective size of the footprint. FYI most equipment racks should have anti tip foot (extensions to the front) to keep their center of gravity from toppling them. Most also have skid feet that were designed to support the rack off the casters, minimally then should be adjusted down so they touch as that will allow sliding but provide better support. Again multiple racks bolted together will provide a very strong unit capable of holding up immense weights. Another disaster trick is if the top of the rack is covered water draining down can't easily get in. Small things can protect the hardware from significant damage. Allison

questions about KIM-1, microVAX-1, and Tektronix 4319

by jonathan＠iastate.edu

Hi, I recently acquired a KIM-1 which is mounted inside a wooden case. The board is stamped with a manufacturing date of 3/78 so it was manufactured after Commodore bought MOS technologies. I know that Commodore used metal cases back then. Does anyone know of any third party manufactures that made cases for the KIM-1? This wooden case I have looks too nice to be home made. Second question, I also acquired a microVAX-1. However, the VT240 terminal I attached to it does not appear to be communicating with the VAX. What should the number of data bits, parity, etc. be set to on the VT240? I've tried just about everything I can think of. Could I be using the wrong cable to connect the VAX console port to the terminal? Any help would be appreciated. Third question, I have a Tektronix 4319 workstation with a dead harddrive. Does any one know what maximum size SCSI drive I can connect to it? Any help would be appreciated. Thanks in advance. Jonathan Kavanaugh jonathan(a)iastate.edu

HP 9000/345

by sinasohn＠ricochet.net

Okay, so I picked up an HP 9000/345 (and a /310) and an HP-IB HD unit with 3 5.25" FH hard drives in it. And I've got an HP-IB cable. So, what else do I need to get a unix-ish box up and running? Note, the HD was not purchased from the same place as the 9000, so the chances of it having a valid OS on it are slim. I did come across the HP9000 FAQ, but it doesn't really address my situation. As I understand it, I can run either HP-UX or NetBSD, of which the latter is the more affordable option? So, any tips on what to do next (aside from hooking them together and turning them on to check for smoke leaks) would be greatly appreciated. --------------------------------------------------------------------- O- Uncle Roger "There is pleasure pure in being mad roger(a)sinasohn.com that none but madmen know."

Mac SE SuperDrive password

by PB14＠leicester.ac.uk

Any ideas on how to disable it - jumpers, key > combos, pull the battery, software, what? The password on an SE can only be implemented at software level on the boot volume (internal hard disk), so you can forget about batteries and jumpers. Guess 1: the password is implemented using a fairly insecure shareware tool. Try holding down the Shift key on boot up. If the Mac is running System 7 or greater this (usually) prevents extensions from loading. You can then try to identify the extension (INIT in older Mac speak) that is locking down the computer. Note: there are one or two utilities that can disable Shift-booting in System 7. Try booting from System 6 or 7 Disk Tools (downloadable from ftp.info.apple.com) which both work fine on an SE. You will need a Mac to generate the boot disk. Try booting from this disk and try looking for a suspicious extension or INIT in the System Folder. If necessary, move all of the extensions (or INITs) out of the system folder altogether (eg folder at root area of hard disk); the Mac SE will still boot without them. Guess 2: If you've moved all of the extensions and you're still getting a password dialog box, it may well be a more sophisticated security tool (eg FileGuard, Empower). Boot from your Disk Tools disk yet again and run "Apple HD SC Setup". With any luck, you should see the name of the hard disk and it will be identified (most likely) as SCSI Device 0. Press on the "Update" button to replace the SCSI driver on the hard disk (surprisingly this will defeat some of the older security tools). Don't be surprised if a dialog box pops up asking for a password. Even then you're not necessarily 100% stuck. If the security software has encrypted the hard drive, the only solutions are to enter the correct password or to format the hard drive. The security software will even try to prevent you from formatting the hard drive but there are ways around this. If the security software has not encrypted the drive, you can boot >from a floppy and supress scanning of the SCSI bus on startup by holding down Command-Option-Shift-Backspace. You can then use a disk editor such as Norton to hack away at the boot blocks to remove the offending software. The hard disk will no longer boot but you can access the contents; running the "Update" function on "Apple HD SC Setup" will repair the disk sufficiently so that you can reinstall the System software.

Dead keys on C64

by jsalzman＠hersheys.com

For Commodore 64 repairs, see Ray Carlsen's repair page at: http://www.prismnet.com/~bo/commie/repair.html Your specific problem may not be addressed here, but at the top of the page, there are e-mail links to Ray. He is very knowledgable and helpful on Commodore repairs. I consulted him via e-mail once for a broken SX-64 I picked up. He helped me get it working again. You can also get schematics of the C64 at: ftp://ftp.funet.fi/pub/cbm/schematics/computers/c64/ Jeff Salzman > Problem: I just noticed the C64 seems to have these dead keys '5, 7, 9, >and 0'.

Once the adapter definition is installed on your system (think of it as a bios extension). Things should boot okay then.

This is the second time I am emailing support(a)compaq.com. Both times, they have given me an automated reply that I should use forum.compaq.com for the information they have posted, which might be what I'm looking for. They warn me of the fact that their state- of-the-art Internet technology (javascript and cookies) won't allow me to use the site without IE3 or Netscape 2. So much for Lynx. And all I wanted was a price quote for a new keyboard for the LTE I got a few weeks ago! I noticed some people on this list have experience with these things, so a)does anyone have any extra LTE Lite/25 keyboards? b)Is the PS/2 port on the back for a keyboard? If so, can I use an external kb without an internal one? I haven't had much luck so far. ______________________________________________________ Get Your Private, Free Email at http://www.hotmail.com

Old computer promotional video's

by cdrmool＠interlog.com

I have recently come across a couple of video's at a thrift shop that were fun to watch. One was called "In business with Macintosh" which was probably from the early 90's and the other was an IBM video of a conference in which they present OOT. Neither are "classic" in their subject matter, but I was wondering if anyone has any that are. I would thrilled beyond belief to see a promo video for "Lisa". I'm sure they must have considering their efforts to sell the thing. Anything old would be a hoot. IBM must have put out tons of stuff. Colan

HP 700/44 terminal to get rid of

A 700/RX (I think) is an X terminal, meaning it wants to talk X over a network (TCP/IP or maybe DECnet, and yes it probably has an Ethernet interface built-in) with X client programs running on other hosts. A 700/44 is a traditional terminal that wants to send characters across a serial line. In particular the 700/44 emulates a PC terminal and DEC VT52/100/200 terminals. It doesn't do all that HP block-mode stuff that I ramble on about sometimes. -Frank McConnell

A few different things

(1) NCS Sentry 3000 Test Scanner (for grading scantron type tests) $25 (4) DEC DEMPERs $10/ea (1) SummaSketch II Tablet $40 I also ran across an HP 700/x X-Terminal. Does anybody know anything about these? It looks like it will run a standard 15-pin VGA monitor. It's dirt cheap and I'd LOVE to have an another xterm around the house. Any info? Thanks rob

through my parents Record collection and found a record that is Moog mus < It was something I was looking for, as it was so unusual that I remembe < when my dad brought it home over 20 years ago. < < Anyway I was wondering if anyone knows anything about what kind of hardw < was used for this? Most of the early Moog work was done an ANALOG synths using multitrack recording as most were not polytonic machines. Names of people who did commercial work were Wendy Carlos, Iaso Tomita and Claude Denjean to name some in my collection (Vinyl). The classic was Switched on Bach, Carlos. Some had primitive sequencers but it would not be until the late 70s that the computer->synth connection would start to really get out of the lab. Allison

More Moog

by fauradon＠pclink.com

Since we're on the subject: I have a small synth that was sold at Radio Shack (Tandy) that is labelled "Mini Moog Music" Are there any relation to the Moog we're talking about or did they only used the name for marketting?

HP 700/44 terminal to get rid of

by rhblake＠bbtel.com

I'm really wondering if you guys are talking about the same thing I am here but I have a perfect condition HP 700/44 terminal with rs232 and current loop connections on back, with keyboard. I believe it's monochrome amber and emulates different systems. This is the last (and best) of the batch I had for sale. I'd like $15 plus shipping for this one. Also still have the Visual 102 terminal with keyboard in breat condition, $10 plus shipping - but a little heavier. The DEC VT 220 is spoken for and the DEC 100 is due to get gutted next week.- -------------------------------------------------------------------- Russ Blakeman RB Custom Services / Rt. 1 Box 62E / Harned, KY USA 40144 Phone: (502) 756-1749 Data/Fax:(502) 756-6991 Email: rhblake(a)bbtel.com or rhblake(a)bigfoot.com Website: http://members.tripod.com/~RHBLAKE/ ICQ UIN #1714857 AOL Instant Messenger "RHBLAKEMAN" * Parts/Service/Upgrades and more for MOST Computers* --------------------------------------------------------------------

Followup on the new Imsai

by Anthony.Dellett＠Staples.com

Well, I finally got it. Took it apart and found that whomever owned it previously already mounted a power switch in the back and runs all the AC voltage thru there. There is alot of corrosion on the ICs in the front panel, I'm going to need to spend some time cleaning everything up there. One switch and two switch covers are broken but those are easy to replace. Four of the 100 pin card edge connectors need to be replaced (two are just way too loose and corroded, the others are broken). Everything else seems to be fine (the power supply is okay and supplying the proper voltages). Now all I gotta do is order all these parts and enough S-100 cards to complete a CP/M system and I'm all set. Wish me luck! Tony Dellett

Dual floppy drive

by mbg＠world.std.com

I recently got one of those combo drives -- the one with both a 5.25" and a 3.5" floppy built in. It is the Teac FD505... I currently have a Teac FD-55GFV (RX33) on my RQDX3 at home... is anyone familiar with the two drives? Can I replace eht RX33 with the combo drive and get it to work? I've already tried simply using it as distributed... and the controller (sorry, its the RQZX1 controller, not RQDX3) sees the two drives. But when I try to access either, they get directory read errors on disks I know should work... Any help appreciated...

S-100 bus termination

by allisonp＠world.std.com

< Originally, the Altair (S-100) bus did not define a need for termination < any kind. It was not until things on the bus started to speed up (usin < DMA and such) that anyone apparently thought about it. The altair bus was never specified, nor engineered. IF it were it would not have been built that way. It was more like people tried to makes them work and found the crashed often and without apparent cause. Other people found if the move the boards from one slow to another would make a program crash. Using an extender card crashed the system. Most all found as they added memory the system would get more or less stable. I was one of the early ones looking at the data lines mostly if horror with my scope. Of the handfull of computer people in the LI, NY area at the time I was one of the few with a scope. < Can't hurt. I will say however, I do seem to recall seeing a board or t < that would not run on a terminated bus, but that has been so long that < don't evem recall what it was.

Zenith Data Systems laptop

by tomowad＠earthlink.net

Just purchased three Zenith Data Systems laptops at a Hamfest - my first IBM-compatible computers, believe it or not (always focused on the Apples & under-the-TV 8-bit systems). Needless to say, I don't know a thing about them. There are no power adapters. I have a 12v 300 mA adapter. Will that work with them? I hooked it up to all three systems - 2 of them didn't do a thing. The third "spins" up and I can hear a very faint wining noise from inside. The monitor, however, shows nothing (could this be due to too little amperage?). The computer gives a three-tone beep every 15 seconds or so (estimate) and beeps whenever I press a key. Anybody have any suggestions? Like I said, I don't anything about these, so any advice would be appreciated. Thanks, Tom -- Sysop of Caesarville Online Client software at: <http://home.earthlink.net/~tomowad/>

Weekend Finds

by foxnhare＠goldrush.com

Having a bit of cabin fever Sunday I convinced my wife (well, not really... she likes foraging as much as I) to go thrifing. First stop in Stockton was the the college parking-lot flea market (never know what you're going to find there.) I was almost empty-handed when I found a a bin of 16 Atari Carts (actually 15 I later discovered as one was missing the guts) paid $5.00 for the lot. Included were few standards such as BASIC, Star Raiders, Defender, and Asteroids but also Atari Assembler, a Dealer Demo Cart, a couple word processors, an "educational system master cart" (networking??? Pilot?) etc. Pretty good find. Still need to test em. Another item, an facinating BASIC book, "Elementary BASIC", a BASIC instructional guide using the Sherlock Holmes character (from the texts of Dr.Watson), in it Sherlock Holmes solves a few cases with programs ran on Babbage's Analytical Engine ('translated' to BASIC by the authors). Pretty off-beat. The last stop was to our favorite thrift store which did well by us again, I picked up an Apple IIc (sans power supply) for $3.98, and a really nifty item, a Sharp PC1501 Pocket calculator w/printer/cassette module (CE-150) in its carrying case with some cables (no ps for these either) for $4.92! Tested the handheld, it works, even though the batteries I removed were drippy; the expansion unit I have yet to get working (not enough power from the adapter I guess??) There is also a cassette tape in there, will be fun to check that out. The Apple will have to wait till I find a PS unit, since it is my first 8-bit apple unit. I have little for it but the computer, a users guide and a few loose disks picked up here and there. I figure I'll collect some of the games I thought were cool for it and maybe a gizmo or two. Ahhh Another beginning, will be fun to discover a tidbit here and there, as finding the Commodore oddities are getting harder to locate. -- -+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+- Larry Anderson - Sysop of Silicon Realms BBS (300-2400bd) (209) 754-1363 Visit my Commodore 8-Bit web page at: http://www.goldrush.com/~foxnhare/commodore.html -+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-

Using IBM floppy-drive cable with Kaypro?

by dpeschel＠u.washington.edu

I've been tinkering with my Kaypro to try to eliminate the errors that drive B has been giving me. Putting in a new floppy drive didn't seem to fix them; I wonder if it's the cable? (As is, the Kaypro supports two drives (SA400 or equivalent). The original owner bought a little hardware thingie that does something to the drive-select signals to add support for four drives; he also added a connector to the cable for drive C between A's and B's connectors. I currently have no drive C, and only drive B is giving me problems -- that's why I suspect the cable.) So I bought a new cable. It has that stupid half-twist, so I'm wondering how to coax my system into working with the new cable. I think I understand the situation from the point of view of the drives (both drives are jumpered as #1, and some pins are exchanged: 10 <-> 16, 11 <-> 15, 12 <-> 14). But doesn't the computer have to cooperate in this farce? That is, would I have to reprogram my BIOS to mess things up in the same way as the IBM PC's hardware, so that the drive cable can do its part and thus it all ends up (sort of) working? It's worth trying the new cable (though it seems rather cheap, and there's a break in the insulation, though that could be because I dropped it on a concrete floor at the store). But if it's too much trouble, I'll skip it. Incidentally: God damn IBM for cutting corners this way, and making people think shenanigans like this are totally normal and to be expected, and messing with a perfectly reasonable interface. -- Derek

Cleaning circuits

by franke＠sbs.de

> A few questions about clean(ing) circuits: > a)Can dust cause any damage to a PCB? Can it short anything? Yes and No - no direct harm is done, but dust turns out to be a good insulator, so the core temerature of the chips rise if they are covered by dust - even a small dust film can be difficult. Higher core temperature means higer stress, more aging and sooner irreversible failure. > b)What do you recommend for cleaning out PCBs if there's lot of it, > or spiderwebs, mold whatever? Yes cleaning is a must. I use several methods: 1. If the board is small enough to fit, I use an ultrasound cleaning device. This method is not usable if stickers or other non wter resistant markings ar on the board (and should be keeprd intact). ultrasound cleaning removes anything in less than a minute. 2. If the board is to big i use oridinary water (but destiled is prefered to avoide calcium (?) stains). Maybe with a little soap in front. 3. If there are some stickers to preserve, I use only short 'splashes' of water, from a mouth washing device. Alle three methods requiere intensive drying. So I first use a soft (frotee) towel, and then wave the board to dry of thebigger parts. If the board is very crowded (like a IBM-PC or XT) I will use a centrifuge (spin dryer). The board has to be fixed to get the right. Also a hair drywer for blowing _cold_ air is usefull to drive out the water. I never use warm air, since it is less efektive and leaves more stains on the surface. But as I said, using destiled water makes it less cruical when it comes to drying. Also 'canned' compessed air as available in some shops can be used to drivew out the water from deep corners. You don't have to remoe all chips. 4) Now if I can't use water, I thake several soft towels (fabric) and rub off the dirt. A sponge with a liite soap water, and a second one with clear destilled water. Also a stick an linnen is usefull to remove dirt from the edges. The ultrasound method can be used for a lot of parts. Even sonme keyboards do well - Original PC-Keyboards could be dumped without any preperation into the water and cleaned in just a few seconds. Oh: NEVER USE ANY CHEMICAL CLEANERS (beside _pUre_ soap) ON YOUR PCBS - NEVER - NEVER - NEVER. > c)Does distilled water cause rust? Basicly almost no, but after touching thesurface it isn't destilled water :) The main reason for rust is high humidity always dry your precesious little ones and store them not in an swamp like climate (sorry if you live in FL or somewhere near the Amazonas). > d)Can distilled water be used to clean circuits? Yes - see above. > e)As I understand, tap/spring/rain/etc. water is full of minerals > and that's why it's conductive as well as rust-causing Yes/no - If you dry them, they won't pick up rust. > f)A while ago, I picked up a bunch of 5.25" diskettes, which I hardly > allowed to dry before I put them into the plastic box. Now I > looked inside, and mold is spreading from the Microsoft Assembler > diskettes onto the Apple II ones. What is safe to use to clean > the mold (it's reeely disgusting!)? Thats the problem with Microsoft - They always want to pollute the environment - and as we see not only the Internet or Java, even simple helpless Apple Disks are to be transformed in non standard monsters :) Normaly I could suggest just to dump them since most of the software is not very unique. But again here are several levels of restauration: 1. If you only want to keep the software: Rip of the cover, clean the disk with cold air and / or alcohol (no nor brandy - use isopropyl alcohol) - take a _clean_new_ linnen and pour alcohol on. now go soft (!) ofer the disk to remove any parts - try to 'roll' the fabric to change the surface and lift of the mold. now place the disk into a new cover (always open only one side). If the disk wasn't damages itself you now should be able to read the content and duplicate it. I used this Method several times in data recovering actions. 2. I you just want to keep the cover (special print, or just since it is an genuine early Microsoft :): Take a sponge with warm destiled soap water and sponge it down (Never look at the disk ... it's a shame :). Drying and now storing a at a dry place to prevent the mold to come up again - Mold doesn't like dry places to flourisch. 3. You want keep both: Combine one and two - so you have a funktional copy and a displayable disk. Or just use method 1 and transfer the label to the _new_ copy. 4. You realy want to keep this disk (worst case): Forgett it - at least You have to do it like in 1) but you'll have to open the original cover _very_ carfully clean the disk, clean the cover AND replace all this fabric fleece inside the disk for new fabric - thats _very_ sifficult - and even if you mange this, the disk well always look damaged. The possibility of reinstaling mold is also the highest. Some tips: - Never use Mold covered Disks - or if you have to, restrict the usage to on 'mold-only' drive. - Don't use disks lying next to moled disks - the little friend is already there. - Store your disks always dry and with enough air circulation.closed cases can be deadly to your Disk. - Avoide high humidity - Avoide low humidity, since the fleece will become damaged. - Avoide heat - Some disks could start to loss their data as soon as 60 degree (140F) - Avoide cold - Never use disks below 10 degree (50F) the stress results in higher aging (remember, flopy disk drives are still cutting tools like a turning lathe) Also the magnetic film will loose the tightening if the temperature is to low (same as when to high (>80 degree 180F) I already dumped several hundered Disks I recovered previously from basements and garages because of Mold.

Apple ][ file conversion

by franke＠sbs.de

> Can I make use of the Centronics interface? What type of 'serial car' > do you recommend? Can I use my Apple //c w/serial port but w/o CP/M? No, or at least not without doing some own programming (the Paralell boards for the ][ uses 652x devices in most cases). Yes, the Serial of the //c is an ordinary, build in Super Serial Card. But the //c will read CP/M files only in RAW mode - so any nibble copy programm (or even RWTS programms) can copy CP/M disks from DOS (>3.2, 16 Sector DOS) or ProDOS. If you want to copy CP/M files logicaly (I think thats what you need for transfer) you could only use the CP/M environment. The best way is to put a SSC in an ][, ][+ or //e boot CP/M and use MODEM7 for Transfer (and _ANY_ programm on the PC :) You could also use any other serial card, if it is supported by your CP/M - But its hard to find anything not SSC compatible .)

hardware keys?

by poesie＠geocities.com

does anyone have any experience using hardware copyright keys? I picked up a couple copies of some software from a thrift shop today and some of them ask for hardware keys- the most info i can find is something about serial card plugs? It didn't have them in the box, and I couldn't track down any info on who donated them. am I completely out of luck ? It seems to me that I would have to buy a whole copy from the original seller of the software, but I doubt they're still in business. any info? -Eric

< How many instructions? I believe the Pentium has on the order of 80, not < sure. More like 100+, not counting all the addressing modes. the instuction set for the 8086 is many times larger than the PDP-8. The PDP-8 instuction set is 47 (most all variations included), it's very minimal. < They weren't networked at all? I mean, there weren't instances of < connecting two machines with cables? Actually there was DECnet-8! Dual processor machines were not uncommon. but they were not networked like you would current machines. It was not the mindset of that era and generally not required.

hardware keys?

by higginbo＠netpath.net

If you want to go the underground route, there are cracking programs that defeat the hardware (dongle) locks on some programs. But I'm not suggesting that you do it or anything.

NeXtStation TurboColor

by thomas100＠home.com

The main problem with these machines is that they are still so heavily used that noone wants to give up the media (cd-roms, etc). You can try comp.sys.next.marketplace. There are also some websites... http://www.orb.com and http://www.deepspacetech.com. Mostly what you probably need is a >300 mb standard SCSI harddrive, a cd-rom player that works with that machine [there are many but not all work] and the cd-rom media (NeXTStep 3.3 is probably the best). If you were near me I'd tell you just to come by and I'd do a builddisk for you. Perhaps someone else will offer. $25 was a good deal- last time I checked they were still going for a couple hundred. Poor kid! Once you get it working there's tons of software around for it, some of it the best quality available... try http://peanuts.leo.org and http://www.peak.org/next. The machines, although great performers for their time are getting slow by today's standards. Because of that, and the fact that Mac OS X Server (aka Rhapsody) is somewhat available, the prices should be dropping lower.

Do you mean compilers (I think DR was the only one to do PL/I), or do you mean application programs for an 8086 that used PL/I? I used the DR compiler to do a sports handicapping system and a mailing list system. It used DR's Acess Manager for the ISAM file system, and DR's Display Manager to draw forms on terminals. It ran on an 80286 based Concurrent DOS (aka MP/M II) custom built S-100 system. I believe I still have the source code somewhere, if that's what you are looking for. Jack Peacock

Using IBM floppy-drive cable with Kaypro?

by maxeskin＠hotmail.com

First of all, I believe it could be untwisted by pulling off the back cover of the connector and pulling the cable off. Also, I believe the IBM controllers walk fine with jumper-selected drives, just that everyone uses the half twist thing. >I've been tinkering with my Kaypro to try to eliminate the errors that drive B >has been giving me. Putting in a new floppy drive didn't seem to fix them; >I wonder if it's the cable? (As is, the Kaypro supports two drives (SA400 or >equivalent). The original owner bought a little hardware thingie that does >something to the drive-select signals to add support for four drives; he also >added a connector to the cable for drive C between A's and B's connectors. >I currently have no drive C, and only drive B is giving me problems -- that's >why I suspect the cable.) > >So I bought a new cable.

Moog more on-topic

by jpl15＠netcom.com

I certainly do not want to propagate any more off-topic stuff, so maybe e-mail would be mo bettah. Having said that: The Model III that I have was used primarily for R2D2, some of the ancillary robot, droid and creature noises, and a lot of the tracks for the Alien Roadhouse Band, etc., etc. Thus I was told by the previous owner, and corroborated by one of the editors who worked on the pic. Csound *is* in the digital domain, but it's output needs to be made into a voltage somewhere; the early PDP11 versions used the DACs of the day... in fact MUSIC IV was used entirely offline, one coded the program, punched cards, waited until the (lowest-priority) job was run [to tape], the the tape(s) were taken to another facility to be rendered through DACs to am analog recording. *Then* you debugged... Zane, I would like very much to have an (archival only, honest!) CD copy of the Hyman recording. BACK ON TOPIC PART: I would love to locate some 70a vintage DACS, prferably standalone boxes, or more DAC cards for my MINC. I am trying to consolidate all the info/software/hardware I can around the DEC Mini line and music. I have a wonderful picture of a PDP-5 system running a music notation and translation interface for MUSIC IV at Bell Labs in the late 60s. It then sent code to an IBM 7094, which output a tape to another machine, referred to only as a "PB 250 Computer" [Pitney Bowes?] [Packard Bell?] which acted as the translator and DAC. I have soundsheets in the book of music realized on this machine, and I'll put them up on my FTP site any day now... (Thanks to Marvin, from whom I stole the book) Damn, drifting off topic again... sigh. I guess I should output a list of my collection.... Nah, too bleedin' hot right now. Cheers to all John

Possible to fix a BA123 power supply?

by allisonp＠world.std.com

< Help? I have 2 power supplies for DEC BA123 boxes which < no longer function. I suspect that in each case, something very < simple has gone, such as the primary capacitors on the AC/DC Don't ditch the failed supplies. They can be hard and expensive to find. First failure mode on them is overheat due to failed fan. Usually that takes the internal fuse. Open with care as the caps in them can hold a lethal charge. Rare is the failure of the caps from what I've seen. The high voltage chopper transistor or the input rectifiers are more likely to be suspect. Allison

Moog (on topic, too...)

by mbg＠world.std.com

> Zane, is your record from Norlin Company? If so, it is the (quite >rare) demo record that Norlin put out when they bought Moog music >from Bob (Moog). I have archived several of these demos, Moog and >ARP and Oberhiem. Be careful if you play it, they weren't on the >best vinyl. Thanks... I couldn't remember Bob's first name... When I was at WPI in the mid-70s, I got a chance to work with the Arp AX and Odyssey (and a few others for which I forget names) to produce some music which was used in a theatrical production on campus (Beltold Brecht's Gallileo)... I loved getting chances to work on those things... > ObCLASSICCMP: One of my intentions for at least one of my PDP11 >systems is to interface it to my Moog, and obtain an old copy of >Csound or the like.. to recreate an exact environment from the >'childhood' of electronic music. About a decade ago, a few friends of mine and I played with some pdp-11 controlled music generation. We got a bunch of the TI sound generation controllers and one person (who was adept at IC circuit design) designed us a circuit for controlling a set of these units from a DR11C (16-bit parallel output). I still have one prototyped at home... it allowed up to 9 voices (three voices/chip, 3 chips) of sound, and 3 voices of percussion. Someone else got ahold of the Stanford music software for the pdp-10 and wrote a pdp-11 version of it... we had it playing a bunch of the old stanford songs, and I entered a few more (like Scott Joplin's "Crush Collision Rag"). Since the hardware connected to the AC lights of the -10 was called the MK10, we called our board the MK11... Somewhere I have the schematic for it... Later on, another friend (hi, Allison) designed a DLV11-J to MIDI interface... I have a couple of Casio CT101 synthesizers and a sequencer...

Cleaning circuits

by allisonp＠world.std.com

< A few questions about clean(ing) circuits: < a)Can dust cause any damage to a PCB? Can it short anything? Yes, it can be conductive, block cooling and host molds and fungi. < b)What do you recommend for cleaning out PCBs if there's lot of it, < or spiderwebs, mold whatever? Vacuum with a conductive (carbon/plastic fiber) brush. < c)Does distilled water cause rust? Rust is the product of oxidation. Air is the culprit. Water _may_ instigate electrolisys if not fully dried and power is appiled. < d)Can distilled water be used to clean circuits? Yes. < e)As I understand, tap/spring/rain/etc. water is full of minerals < and that's why it's conductive as well as rust-causing Not enough to be a significant problem if it's dried. I have been known to put grungy boards in the dishwasher. Works very well. The board must be completely dried (160-180F overn works well). < f)A while ago, I picked up a bunch of 5.25" diskettes, which I hardly < allowed to dry before I put them into the plastic box. Now I < looked inside, and mold is spreading from the Microsoft Assembler < diskettes onto the Apple II ones. What is safe to use to clean < the mold (it's reeely disgusting!)? Dish soap and water.

The Moog

by healyzh＠ix.netcom.com

I've recently gotten the necessary hardware and software together to transfer Records (16, 33, 45, and 78) to CD. As part of this I was digging through my parents Record collection and found a record that is Moog music. It was something I was looking for, as it was so unusual that I remember when my dad brought it home over 20 years ago. Anyway I was wondering if anyone knows anything about what kind of hardware was used for this? Zane | Zane H.

toshiba T3100/20 20mb RLL HDD

by poesie＠geocities.com

ok, yet another Q for those of you out there who have run across these. anyone have a suggestion for where i might come across a ~20mb RLL drive? 3.5" size, don't have the model #'s on me at the moment although I recall with the toshiba it was a JVC. seems to me from what I could pull off the net that these drives seem to die often. -Eric

Zenith ZWS 248's FS or trade

by rhblake＠bbtel.com

Ok, this is a repost since the original responder had to back out for whatever reason... I have some excess Zenith Z248 equipment to get out of my way and would prefer a trade of other equipment for these.. I have two ZDS ZWS 248's, these are the planar units that the 286-12 processor board plugs into. Complete main units with the planar board, power supply, cpu board, I/O board HDD/floppy controller (MFM), MDA video card, drive bay inserts, etc. You need to add drives and it will take any drive from 360k to 1.44m. It takes all sorts of MFM hard drives as well and can probably accomodate an SCSI or ESDI in place of the MFM controller which will allow larger drive types. 512k on the cpu card. They have two open 5.25" bays, one has a filler that can be removed. There's also another identical unit without a power supply. It's a case, planar board, drive bay inserts, 2 I/O boards. Mostly for parts or use to build up with parts you find elsewhere. I need $25 plus shipping for ALL THREE (as a package) or will trade for something that I can use such as cdroms, hard drives, SIMMs, microchannel adapters,etc, etc, etc.... I would really like to get a couple 2X or higher SCSI cdrom drives, caddy type or tray load or larger SCSI hard drives whether full, half, 5.25 or 3.5"... Drop me a line if interested. I also have two ZDS memory cards that work on these to bring the 512k up past 1024k that I would like $10 each or trade for. They are not open to sale/trade until the other units are gone and the new owner decides they don't want them. -- -------------------------------------------------------------------- Russ Blakeman RB Custom Services / Rt. 1 Box 62E / Harned, KY USA 40144 Phone: (502) 756-1749 Data/Fax:(502) 756-6991 Email: rhblake(a)bbtel.com or rhblake(a)bigfoot.com Website: http://members.tripod.com/~RHBLAKE/ ICQ UIN #1714857 AOL Instant Messenger "RHBLAKEMAN" * Parts/Service/Upgrades and more for MOST Computers* --------------------------------------------------------------------

<10 yr question here - 1.8" form factor HDD?

by poesie＠geocities.com

are there hard drives for laptops that are smaller than the 2.5" drives? I have a laptop that takes an IDE hdd, but the space is about 3/4 of an inch to small to even fit a 2.5" drive. I vaguely recall seeing something about 1.8" drives? Am I hallucinating here or does such a creature exist? -Eric
