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

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.

Don't know about that, but when I worked in Silicon Valley for a well known microprocessor manufacturer, one of our pieces of state of the art lithography equipment was controlled by micro pdp-11s.

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

by roblwill＠usaor.net

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.

If it is the same machine, it'll take standard 72 pin SIMMS and an IBM PC keyboard (with a PS/2 style connector). 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. In a message dated 98-07-30 21:56:22 EDT, Sam wrote: << Another good rack is the Metro brand. They are a wire mesh shelf with hollow tubing for the supports.

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

PC Service Source, in my reseller experience, seems to always charge high prices & take forever for parts they say are "in stock". not bad for some things, and they will try to get things you can't find anywhere else; but they are rather irritating because several times we were told the parts were in stock and ended up waiting months for them to become available. my two cents. -Eric P.S. - If anyone is interested, I'm willing to provide an edited copy of my windows cardfile of vendors. have about 1000 pages, w/ contacts for alot of diff manufacturers. email privately if interested. :) Wayne Cox wrote: > PC Service Source www.pcservice.com (sorry to mention the "P" word > here) Parts for all kinds of systems, printers, and peripherals. > Including old first-gen laser printers. > > -Wayne Cox

Dead keys on C64

by maynard＠jmg.com

Well I landed an amazing C64 software score, with boxed sets of Ultima I, all the Zork series, Neuromancer, an editor assembler package, a koala pad, a bunch of joysticks, and a bunch of other stuff I can't remember. The boxes and manuals are in almost _pristine_ condition! Didn't pay a dime... one of the guys I work with was amazed that I liked this stuff and pulled it out of his basement to give to me for a beer. Well, OK; I paid a beer. ;-) Problem: I just noticed the C64 seems to have these dead keys '5, 7, 9, and 0'. Looks to me like a dead bit on the keyboard controller, but I must confess to ignorance on the internal details of how the C64 accepts key presses. Can anyone give an overview, and would anyone know of a fix? Thanks, --jmg

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

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.
