Stuff I need to get rid of

by nerdware＠laidbak.com

Hi, gang. I have a boxed copy, on tape, of Island Write/Paint/Draw for SCO. It was given to me a couple of years ago, and since I have neither a tape drive of the necessary format nor a SCO box, I really don't need it. Pay shipping and it's yours. If you need more details, email me off-list and I'll see what I can come up with. I also have an old Intel SBC developers board with some docs. Don't know if it works or not. It's a little dirty, but considering it's age...if you need more details, email me. Once again, pay shipping, give it a good home, and it's yours. Thanks!

Usually the address for the memory preceeds the data. If the system expects DRAM it's often far earlier to permit the MUX operation. However, in the PC world where the conversation started considerations of MMUs and the like were limited to the older 286s as the 386 class and later were alrady delivering physical addresses to the memory subsystem. >Now, suppose the parity calculation takes p ns. Now, if the parity >generator circuit can get the raw data more then p ns before the address >can be got into the RAM, then the parity logic is not slowing things down >at all. The parity bit is available before the RAM can use it anyway. Save for that is speculative as most cpus deliver data AFTER the address of in coincidence at best. Even then it's meaningless as the timing relative to what ever strobes declare the address valid and qualify the data read or write. One generalization that has mostly held true for most years is that memory (at the system level) usually slower than cpu. This leads to things like pipelining, caching and burst mode(block) transfers to get stuff in and out of the finite bandwith resource. That consideration was as true for the PDP-8 as latest PentIV/1.4G. It's also true that things like DMA and video(bit blitters) are also competing for the same ram bandwith. Allison

TI ASC

by jbdigriz＠dragonsweb.org

To make up for my blunder (too much Canadian on an empty stomach interferes with the keyboard-mashing apparatus), can anyone give or point me to some solid information on the aforementioned machine? All I can find on the Web is pretty vague. Also , it looks like only 7 or so were actually built. Were they all eventually turned into Toyotas, or does anything remain of them anywhere?

True? > >There's no reason at all why parity memory should be faster than >non-parity memory. Parity memory just stores a parity bit for each byte The assumption is that parity is available at the ram at the time of write and while true it was calculated some where. Parity can only be calculated (simple combinational logic with attendant delays) at the time of a wirte so the write must for a given ram speed take longer. So if you want the parity to fit in a given memory write cycle time you must use faster ram. >of normal data, so you can detect (but not recover from) some memory errors. There is also ECC ram, those are slower (over all) as the ECC bits have to be calculated. Expensive, errors are caught and recovery is possible. Allison

Upcoming swap + clearing space

by kyrrin＠bluefeathertech.com

CC to port-vax and classiccmp. I'll be hauling a goodly amount of stuff to the upcoming Puyallup electronics swap this year (Saturday, March 10th, Puyallup Fairgrounds, WA), but I've also got some stuff that I know would probably never sell. With that in mind, I'd like to offer the following to the listmembers. Two complete VCB02 video subsystems, including board sets, cab kits, monitors (VR290's if I'm not mistaken), keyboards, 'hockey-puck' rodents, and cabling. These are out of MicroVAX II's. A MicroVAX 2000 "Lunchbox" system. This is one that I kitted out to do low-level formats on RD52 and RD53 drives in the form of adding a longer-than-normal flat cable so the drive could be placed outside the box and still remain connected. I'm pretty sure I have a couple of BA23 boxes I can part with. A DSD-880 floppy/hard drive subsystem with manuals, diag diskettes, and at least one Qbus controller. I may or may not still have a Unibus controller for it as well. Note that this is the only piece I'm going to ask for actual money on (see below). I know I have some MicroVAX II CPU/Memory board sets. I can probably stand to get rid of them. Various other bits and pieces that I have yet to go through. Possibly a VAXStation 3100, probably a DECStation RISC box as well. I've yet to look. I would far rather see this stuff go to good homes than see it scrapped, but I know it's sometimes hard to put a price on things. With that in mind, here's how I'm going to work it. The only piece from this list that I'm going to ask for actual money on is the DSD-880, mainly because it's complete right down to the rack slides, and was known to be fully functional when removed from service about two years ago. I would like to ask $50 or best offer for it. As for the rest of the stuff, it's going up as "Free to good home, but donations to the 'Classic Collecting Fund' will not be refused." ;-) Pickup would be in Kent, WA, southeast of Seattle by about 30 or so miles. I would greatly prefer not to ship anything due to other time-constraining activities like school, running a side business, etc. Get in touch with me if anything looks tempting.

Yep, though the RD52s are likely the most reliable of the pack and if the problem is not in the HDA a board swap is possible. It was a direct approach.

It will be used to support an existing VAX in our system. If anyone has one or can tell me where to find one, I would appreciate it very much. Joseph Gaspard How do you mean "support"? Is this going to be "up on blocks" or are you going to cluster or just use as a contingency system? Try Island Computers ask for David Turner dbturner(a)islandco.com 877-636-4332 Tell him I sent you.

I copied them to RD52s (quantum D540) as they are the most rugged drive I know and I had 8 of them free. That's enough to hold 24 RL02s and be bootable with RT-11. For safety the most important ones are duplicates (used two RD52s as images of each other). Testing so far says RD52s have a shelf life of not less than 12 years. Allison

Comments on these RT-11 Books?

by healyzh＠aracnet.com

OK, I just found online and purchased the following books: Programming with RT-11 Vol. 1 Program Development by Clinch, Simon & Stephen Peters Programming with RT-11. Vol. 2 Callable System by Peters, Stephen, et al. Working with RT-11 y Beaumont, David, et al. Tailoring RT-11. System Management and Programming Facilitie by Clinch, Simon, et al. Now I'm wondering if there are any other books on RT-11 available (besides the actual doc sets) and if these books were worth getting? Zane

Do you know if a M8061 (RL01/RL02 > controller w/22 bit addressing) will work in a uVAX II? I have used an RLV12 in a uVAX-II (in a BA-23 upgraded by DEC from uVAX-I to uVAX-II, just for painful accuracy). It's one of my favorite ways of migrating smallish amounts of data between DEC boxes not on the same wires (site-to-site moves), at least it was back in the days of 1200 baud dial-up. Never underestimate the bandwidth of a VW Beetle with a backseat full of 10Mb removable cartridges. > I have a number of RL02s that I want to archive, but I don't want to > load them into an unknown drive hooked to a system of unknown status > running software I don't know...

My problem at the moment is a lack of happy RD54s in my BA123. I'm about to stick a KDA-50 in that puppy and fire up my MBA ESDI<->SDI box that happens to have a couple of 1.2Gb 5.25" disks in it. If that doesn't do it, there's an RA-81 in the same rack as the MBA box, but I'd rather not heat my house with it. -ethan ===== Even though my old e-mail address is no longer going to vanish, please note my new public address: erd(a)iname.com The original webpage address is still going away.

vax go bye-bye

by cmcmanis＠mcmanis.com

Sigh, just thought I would relate a tail of woe, not sure what happened but if someone has something to try I'm open to it. I've got a DEC VAX 4000/60 that I've been running VMS on lately. I shut it down and took it apart to take pictures of it for the "House of VAX" pages. I carefully re-assembled it and when I turned it on again it wasn't working. The failure mode was "all lights on" which on the VAX generally means that it didn't get through the basic system integrity tests. Yikes! I turned if off, carefully re-checked my assembly and verified everything was correct. Tried re-seating a few of the connected bits (lights & switches, frame buffer, etc) and nada, zip, same dead machine. One person suggested that the PSU might be misaligned, I verified that this was not the case. I verified that the PSU voltages are all correct, and replaced the PSU to be sure that I had a good power supply. Then I tested the old one and it works fine (well I can draw a couple of amps out of all the voltages and they stay solid). Then I took the memory and verified in another vax that it was still ok. It was. Then verified the frame buffer and scsi drives. Everything still works, just the mainboard refuses to do anything. Does anyone have the pinout on the VAX chips on the board? I could check for clock I suppose and see if the oscillator can took a dump, but beyond that I'm stuck. Since nothing else seemed to die I can't imagine what fault would cause these symptoms. I even reset the NVRAM in an effort to verify that it hadn't been corrupted somehow. Very strange, any clues or other avenues to explore would be appreciated. --Chuck

Long-Planned Apollo Rescue Finally Goes Down

by dhquebbeman＠theestopinalgroup.com

I can happily report that a rescue I'd been trying to coordinate since July finally took place. I'd been hanging out in the USENET newsgroup comp.sys.apollo for a while, hoping to find someone who would be willing to donate some Apollo hardware for my collection. Apollo was formed by people from Prime Computer, and the architecture of their operating system (Domain OS/Aegis) grew out of issues they found that they couldn't achieve with PRIMOS (notably, a virtual memory that can be shared across the network). So, it came to pass that a software engineer from Cummins Engine (maker of the diesel engines used in Dodge Ram trucks) contacted me. He was helping to decommission the Apollos that Cummins had been using. Way back in July, he set aside the following items, which I was to go and pick up. However, at the time, my car was facing imminent breakdown (which finally occurred in October), so we went back and forth looking for a way to make the transfer. Finally, he decided (after being reallocated after a reduction in force) to bail and head to Kalifornia. Befre leaving, he decided he'd just bring the systems from Columbus (Indiana) down hre to Clarksville to me! Not just a rescue, but I got them to bring the systems to me! Anyway, here's a thumbnail list of what I got: one DN2500 workstation two HP425 workstations one Apollo 19 inch monochrome monitor one HP 19 inch monochrome monitor three apollo keyboards with Logitech mice an external shoebox hard drive for the DN2500 that contains the latest version of DomainOS, 10.4 and a virgin registry an external shoebox containing an Exabyte 8mm drive (probably an 8200) two apollo token ring cards, four interface boxes, and four boxes that let you switch nodes in and out of the ringnet All in very clean shape! The HP 425s each contain two hard drives, and have Ethernet built-in (thinnet & AUI). The DN2500 has a single ISA slot which currently contains an Ethernet card. I'll be saving the token ring hardware and will play with it, but will likely use the Ethernet on a regular basis. The only glaring ommission: No paper documentation. The newsgroup has a very well-developed FAQ, and there are many resources on the web for Apollos. Th first thing I'll need to do is to back up the DN2500's shoebox drive, so that I can put it back in the virgin state if need be. Personally, I'm grateful that the engineer took the time to put a fresh OS on the system; I know that some of you like rescueing systems taken directly out of service, so that ther actual day-to- day use can be documented and preserved. However, while I think that's cool, I think I prefer hat I've got. The engineer had intended to help me set up the systems and get them running, but I really don't have room to do that right now, nor do I have the time. These systems almost don't qualify (the 425's were made in '93), but it's a dead architecture, so anything so consigned should probably be exempt from the 10-year rule. Well, that's all for now; I've had no prior experience with the Apollos, just considered them kindred to the Primes, so I was someday going to have to have them. Regards, -doug quebbeman

No subject

by william.webb＠juno.com

I just recently acquired a whole bunch of stuff out of a company's basement, including a VAX-11/780, VAX-11/750, 4 RA81's, a TU80, a pdp-11/44, 4 RL02's, an RP06, a TS11, and spare parts and printsets galore. (Yes, John Foust, the little pdp-11/44 in Milwaukee led to all that.) All the equipment was brought up a flight of carpeted stairs by a refrigerator dolly and human power, except the RP06 and the 780 where we used a come-along and a lifting frame I made. Heavy! Anyway, the 780 needs a floppy to boot. The previous owner says he doesn't have it, and I can't find it (although I'm not done searching yet). Is this the sort of thing that is generically available, on the WWW for instance, or is it something that is built up specifically for the mix of options I have in the machine? Incidentally, does anyone here that has a 780 (I know there are several in the group) run theirs? It takes 3 phase power, but there are no loads connected phase-to-phase, only phase-to-neutral (although there is a small 3-phase transformer in the power controller, it could probably be wired to only use one phase or else bypassed completely) so it can run entirely on 110 volts, at about 60-70 amps continuous draw. I was thinking of using split-phase 220, putting 2 phases on one hot and 1 on the other, then putting the Unibus cabinet and disk and tape drives on the hot with only 1 phase on it. I figure this would about balance the draw at 40 amps, 220 volts, which isn't too unreasonable. Richard Schauer rws(a)enteract.com Richard, you *really* should post this on comp.os.vms. These guys are before my time, as I didn't start doing VMS until 1990. Also, see how far back the Encompass (formerly DECUS) hobbyist program goes. You might get free licenses.

DEC DB15 "terminators"

by optimus＠canit.se

I've recently encountered some odd DEC contraptions, looking like baby SCSI terminators. They are plastic shells with a DB15 connector and a green LED at the end.

Windes ME

There is another set of packages I know are real that work even 8086s that are very small but this one claims more and is far smaller. I'm not a believer. FYI: it's only 2mb!

Intel ???? rescued, weekend finds

by rigdonj＠intellistar.net

I went out to a scrap place yesterday and found a large white Intel box sitting out in the dirt. It looks like some kind of emulator. It's *about* 12" tall, 24 deep and 16 wide. There's no marking on the front except "Intel" on the top RH corner. It looks like there may have been another tag on the front at one time but it's gone now. The back has a tag that gives the voltage, etc and says model no. "PIII515". There's a large ribbon cable connected to it that ends in a cigar sixed box. A thin flex cable comes out of the other end of the box and has plug on it. It's marked "286" so I assume it replaces a 286 CPU. There are no displays, switches or other controls on the box. However it does have some more sockets on the back but I didn't note the labels on them. Does anyone know exactly what this is? Of course, we brought back with us but it's now here now so I can't give better details. Other finds included an I/O expander for the HP 1000 (pn 12979), a HP MultiProgrammer and lots of extra cards, a complete monitor for a HP 9835 (With a good CRT! Yippee!), a pile of VME cards, a CPU card to replace the bad one in Bob's Sun 670(?), two more Exor-bus cards (Hey Mike!), a big pile of chip clips and EZ-hooks, several HP-IB cards for PCs, also three circuit boards and a gyro from a Hellfire missile!

NeXT equipment available

by mtapley＠swri.edu

NeXT wanna-owners: A surplus electronics place, Electronics Plus, located in Kerrville, TX (about 70 miles from me) has contacted me with a surplus of NeXT equipment. They have N4000A monitors, keyboards, and mice - no CPU's, but if you have or contemplate acquiring a headless system, these would (obviously) be useful. They are as-is, and "the dust is free". Contact email address is sales(a)elecplus.com or phone 830-792-3400 and ask for Cindy. (You are welcome to mention my name if you wish.) I believe she is looking for prices in the $10-20 range for the monitors; I don't know whether she's willing to box and ship, but I can help out with that if needed. Electronics Plus has about 10,000 square feet of space, with a very wide variety of equipment, from military surplus to just about anything else. Cindy specifically mentioned AT&T 3b2 equipment and IBM printers and other systems. I have not been there yet, but plan to soon, and I'll try to take notes/digital snaps on anything I see that looks interesting. - Mark

KIM-1 paper tape format

Anyway, without further ado, here's the link: http://www.gifford.co.uk/~coredump/mosptp.htm Hope this helps anyone who's trying to get data on/off a KIM, or indeed anything that uses this format.

FS: IBM/Lexmark 4033-001 TR print server

by russ＠rbcs.8m.com

I have one excess IBM/Lexmark model 4033-001 token ring print server to part with for what I paid for it. It's in like new condition, has the power supply and manual. Has it's own unique ID, 16/4 switch and serial/parallel ports. The serial port is a standard 9 pin d-sub and the parallel is a standard 25 pin d-sub. It does not include a token ring whip, you add your own style with 9 pin end to the unit. The 4 I installed on an AS/400 network and they flawlessly installed and I have spoken with others that have used these on System/3x and RS/6000 systems without problems, although they say it's a little more manual due to the older OS. The unit is in great cosmetic shape as well. I had bought 6 of these and used 4 on a projest and had 2 left. One is now spoken for and I have the last one left(the best of all of them I think). I paid $7.50 per unit and that's what I need to get from it plus shipping. Shipping should be minimal as the whole unit w/PSU weighs about 2.5lbs (prob 3 packed). I would prefer that this be shipped only within the US 50 states and APO/FPO addresses to preclude all the time I'd have to invest in international shipping documents. If I don't get this unit spoken for by Monday 1/29 I'll be putting it on eBay. Russ Blakeman Clarkson KY 42726 USA

Sun monitor cables

by alex＠linuxhacker.org

Hi, does anyone know where I can get hold of Sun monitor cables (ideally in the UK)? I have four SS2 pizza boxes, an IPX, monitors, keyboards, mice, and lots of external drives, but no monitor cables! I did get one of them running after wiring the monitor with individual soldered wires from connector to connector, and I have also had a couple of them running over a serial console, but I'd like to get some proper monitor leads so that I can set them up and sell them as full systems (I want to keep one for my collection, but the rest are just taking up space that could be used for other junk, er, classic hardware). They use 13W3 D type connectors, and I did actually manage to get hold of the connector shells from Farnell, but they don't seem to be able to get hold of the signal pins for them. Also, about half of the external SCSI boxes use a weird oversized-D SCSI connector (I think it might be an early SCSI 1 format) that I haven't been able to find cables for either. I'm not as bothered about those, but if anybody knows where I can find them (and adapters to SCSI2, which is what all the controllers use) cheaply, that would be cool too. -- ------- Alex Holden ------- http://www.linuxhacker.org/ http://www.robogeeks.org/

I am actively looking for a working DEC VAX 4000/200 with Open VMS, drives, SCSI capable and in good repair. It will be used to support an existing VAX in our system. If anyone has one or can tell me where to find one, I would appreciate it very much. Joseph Gaspard Senior Systems Engineer GensiaSicor Pharmaceuticals Irvine, California.

applicationDEC 433MP

by gregorym＠cadvision.com

I spent an enjoyable weekend dissassembling, cleaning, and re-assembling a 433MP (introduced 1990, so just on-topic). It came from an industrial environment, and was one of the filthiest computers I've ever seen. I didn't get any manuals, and there's very little info about these machines on the Web (Compaq, as usual, pretends these machines never existed), so I was hoping one of list DECkers could help with a few questions: - the machine has 2 memory boards, which give a maximum of 32 megs of ECC RAM, with 40 x 1 meg SIMMs. Can the system use more than 2 memory boards, to go to 64 megs? Or can the 1 meg SIMMs be replaced by 4 meg SIMMs? - on powerup, the system BIOS reports 640K of main memory, and 13312K of extended memory; there are 25 x 1 meg SIMMs installed, so I'm expecting 20 megs after subtracting the ECC SIMMS. Any ideas why the BIOS isn't seeing all of the available RAM? - the system has 2 x 486/33 processor cards installed - one base CPU card, and one CPU/SCSI card. The system can hold up to 4 processor cards; were there any OSes that could use 4 processors at a time? Is it worth hunting down two extra CPU cards? - there's a TZK10-AA tape drive in the system. What tape cartridges does this drive use? - the processor cards use Intel 80486 DX chips at 33 Mhz. I dimly recall that the 80486DX2/66 is a drop in replacement for the 80486DX33. Can I get a quick speed boost by swapping the processor chips? - finally, how popular were these machines? They're nicely built and engineered, but I had never heard of them before I found this one, and the MicroPDP-11 that I got with it ... but that's another story. Thanks a lot for any help.

Apple Floppy Controller schematic - anyone?

by philpem＠btinternet.com

Hi, I'm currently designing and building a 6502-based computer system for my own use. Right now, everything is done. Except the damn floppy controller. I read about the Apple floppy controller on the 'net (woz.org) and I would like to get hold of some schematics. Anyone got any idea where I could get these? Better yet, anyone mind scanning and e-mailing me it? Thanks. -- Phil. http://www.philpem.f9.co.uk/ philpem(a)bigfoot.com PGP Key Fingerprint: 1FA6 6C7F A2FD BB15 84BF 4993 2B27 0628 E54E 33B1

KIM-1 restoration advice sought

by archer＠topnow.com

I have a partially-functional KIM-1 (date code 0378) I'd like to restore. (And if anyone has one in good condition to sell, I'm also interested.) Currently, there are two things wrong, and I'm looking for general advice on what if anything can be done to fix them: 1. The keypad is pretty flakey. Several keys register erratically, and when they do, they bounce and report multiple times. The '0' key is particularly bad in this respect. The 'PC' key is utterly caved in. But all but the PC key registers in with varying degrees of retries and effort. I'm handy with soldering, and could remove the keypad, but don't have any idea how to clean / fix a keypad, let alone repair any broken springs, contacts, etc. Can it even be done? Has anyone here even seen the inside of one of these? 2. The cassette interface doesn't read. It writes fine, the +12 supply is showing up where it's expected (pin 8 of LM311) and +11-ish on the 565 PLL, but I have no idea what the "normal" voltages on each pin are to assist in further troubleshooting. All I'm sure about is that the output of the LM311 is not anything like what's expected, and the trimpot doesn't affect the PLL frequency one iota according to my scope. Any thoughts on how to tell what section is bad? Thanks for any ideas out there. In the meantime, I am thinking of wiring an outboard keypad and hooking it to the application connector. Hand-wired, of course. Where else would you find a 3x7 matrix? .

HP 95LX at a good price

by spectre＠stockholm.ptloma.edu

eBay's prices for HP 95LX's are ridiculous. It doesn't have to be the 1MB model but I need another one to do some hardware hacking on. Does anyone have a source for these, or would be willing to sell? Also, I came up with an Aquarius 4K memory pack this weekend. Seems to be in good condition. If anyone's after one of these, let me know and we'll work out something. -- ----------------------------- personal page: http://www.armory.com/~spectre/ -- Cameron Kaiser, Point Loma Nazarene University * ckaiser(a)stockholm.ptloma.edu -- The optimum committee has no members. -- Norman Augustine ------------------

HP 9000

by optimus＠canit.se

Last night, at the user group, we tried to fire up an old HP 9000/822 (I trust this falls inside the classic frame?). Unfortunately, the key has been lost somewhere along to road, so we had to hotwire it (is this the correct term?). We have two large sets of manuals, but they only cover HP-UX and various monitors, so we have no idea what all the error codes at the front panel might mean. Also, where do we connect a console? We've got two serial muxes at the back, as well as ethernet, but that's all the I/O we've been able to find. Any pointers to useful beginners' HP?

This could just be someone having their system setup to report as being something else.

A couple of years ago someone posted a bit of this macro like >code to alt.folklore.computers with a brief description of how it all >went together. A dejanews hunt might even find it. But that has little to do with my comment since Atari BASIC is not Microsoft BASIC. MS BASIC was available seperately. Atari did thier own interpreter which was written specifically for the 400/800 series machines and incorporated functions specific to the hardware. Commodore on the other hand did not build this same level of functionality into thier variants of BASIC for the C-64 and I was just wondering if anyone knew if the MS BASIC available for the Atari had any of it included. By your comments above, I would assume not. Jeff (replying to this from work)

I bet it's a relatively ordinary pinout...probably the ROM version of a 2716 or 2732. I believe those chips have part numbers like "2316" and such, if memory serves. There were lots of mask ROMs that were pin-compatible with EPROMs in that era, before one-time programmable EPROMs (plain EPROMs but in plastic packages with no erasure window) became cost-effective.

Large hard disk

by alex＠linuxhacker.org

I have here a large hard disk drive which I know very little about. It is very solidly built of what looks like thick aluminium castings (with lots of fins) which has been anodised to a kind of light grey-gold colour. According to the bathroom scales it weighs about 37.5Kg or 85lb, and is about 40 * 27 * 34 cm or 1'4" * 11" * 1'1" in size. There is no control circuitry in or on the drive itself as far as I can see. The heads are connected to two 40 pin IDC connectors on top of the unit marked CN91 and CN92, the head motor is connected to a two pin plug marked CN93 underneath the unit, and the platter motor (which drives the spindle directly) is connected to a 5 pin plug marked CN94 to the left of CN93. There is an empty space for a CN95 connector next to CN94, and there is also a connector marked CN95 on the main drive motor itself (it looks like a position sensor). The mounting frame is shock mounted to the base via four rubber bushes. On the mounting frame is a label which says "B030-4840-T031A". On the top cover panel next to the head connectors is a label with two barcodes on it, one above the other. Below the top barcode it says "S/N A43396 REV B0". Below the bottom barcode it says "C/N 1A9840". On the casing above the head drive motor is another barcode label which says "S/N 3A43396". The main drive motor has a label that says: UGBT1D-TP0FU11 B90L-1560-0101A 24V 4A 701297-2 YASKAWA ELECTRIC JAPAN I don't have a digital camera, so no pictures I'm afraid. Does anybody know what this drive is, how old it is, what type of machine it was used with, what capacity it is, how much it cost when new, etc. Also, does anyone have a use for it? I'm willing to give it away to a good home, though I'd rather it was collected in person (from Burnley, in the NW of England). Failing that, I'd be willing to accept the cost of the postage (bearing in mind that it won't be cheap due to the weight) and a reasonable contribution towards the cost of packing materials and the effort involved in lugging the thing to the post office. -- ------- Alex Holden ------- http://www.linuxhacker.org/ http://www.robogeeks.org/

Bondwell Model 2 up for grabs in UK.

by kevan＠heydon.org

Is there anybody out there, preferably in the UK, that wants a couple of Bondwell model 2 laptops. They both work, I have floppies for CPM and various other bits of software. I have currently found one of the power bricks, but I am sure I have another somewhere. -- Kevan Collector of old computers: http://www.heydon.org/kevan/collection/

O.T.: Compu-Voxx

by bobcaar＠cyberdude.com

larry: I've got a couple of these units too. It records about 20 seconds of sound (at least mine do, I believe there were other models) and plays it back in a loop at the desired FM frequency. The input power is a 5 pin male DIN rated 22VAC and 20VA (reads on supply). Looking at the the plug, from left to right the pinout is as follows 1 4 2 5 3 (with standard DIN numbering, measured with multimeter): (1) 23V [between 1&2] (4) n/c (2)common (5) n/c (3) -11V [between 1&3 or 2&3] 1 3 4 5 2 I believe this unit only requires 22VAC between 1&2. These units were used in realestate to give a short blurb about a house. Apparently they retailed for $11 000 (?) back when the previous owner bought them.

Smith-Corona Daisy wheel supplies

by nerdware＠laidbak.com

Hi, gang. I'm going through boxes of stuff, and came across a pile of ribbons and several daisy wheels for a S-C printer that came with the one Kaypro II I was given. I'll never use all of these ribbons or even the alternate wheels....if someone can use them, mail me off-list and we'll work out the details. I'd hate to pitch 'em, but I need the room. Thanks.

Altair32 Emulator Project Update

by rcini＠optonline.net

Hello, all: The Altair32 project is progressing nicely. I've completed the coding, so it's feature complete *except* for the Telnet server code. The emulator now can load and save files, accept disk images (the "controller" is the standard MITS 88DSK), and produce printer output. I also modularized it a bit so that it's easier to add devices to it in the future. Obviously, the Telnet server code is key since that's what will serve as the attached terminal. So, we are unfortunately still restricted to using the FP. I have a few bells and whistles I like to add. For example, I'd like to add real Altair fan noise. Spin up. Run. Shutdown. I'd also like to change the FP to the original 8800 instead of the 8800b that was originally used. What I'd want to do is superimpose the graphic switches and LEDs over a picture of an actual 8800. The existing graphics size is 600x320, but I can make it larger if need be. I haven't posted the code to my Web site yet because I'd like to first offer it up for "beta testing" to the ClassCmp group. If anyone is interested in seeing the full source distribution including bitmaps and VC6 project files, please email me off-list and I'll send you a zip file. Just a personal reflection. Before this project, I never programmed in C, much less in "Windows." What a learning experience. I do have to say, though, that C is fairly easy to learn and use, but I'm sure that I'm only using about 20% of what C offers. And even at the end of the project, I still have trouble with pointers :-). Rich ClubWin!

need information on CDC Sabre 9720-736 SMD

by red＠bears.org

Can anybody please tell me or point me to a diagram explaining which connectors on the back of this disk are for what? In addition, an explanation of how to interpret the diagnostic LEDs on the top panel would be most helpful. Tony, thanks for your information. It was a good start for me, but I need some drive-specific information now. Seagate's web pages are worse than useless for this. ok r.

Sun monitor cables

Farnell do list the coax inserts (they also stock the high-current power plugs that can be used in other 13W3 appications), and IIRC they list the 13W3 shells in two places in the catalogue (which I don't have handy). They might be out of stock, I suppose. If so, you can also get them from Electrospeed (www.electrospeed.com): 169.23.1415.421 50 ohm straight plug 252-38733D ?4.08 23.2415.421 50 ohm straight socket 252-38734A ?6.17 FMX 003 P102 75 ohm straight socket 252-3104J ?3.05 FMX 003 S102 75 ohm straight plug 252-3106A ?2.36 (I'd check those part numbers; S102 sounds like it should be a socket and P102 sounds like it should be a plug!) Electrospeed also sell Siemens inserts for DIN 41612 mixed-body connectors, which AFAIK are interchangable -- but the Siemens ones are (even) more expensive. You can also get them from RS (rswww.com) or Electromail: 485-164 RG178B/U straight plug ?4.16 485-170 RG174A/U straight plug ?4.57 485-186 RG178B/U straight socket ?4.84 485-192 RG174A/U straight socket ?3.89 You can get the cheap version from CPC (www.cpc.co.uk): CN04661 RG179B/U 75 ohm plug ?1.43 CN04662 RG178B/U 50 ohm plug ?1.43 CN04663 RG179B/U 75 ohm socket ?1.52 CN04664 RG178B/U 50 ohm socket ?1.52 You can get Sun-to-VGA adaptors (both genders), half-pitch 50 D plug (SCSI-2) to 50-pin 3-row D (which is probably what you called "weird oversized-D"), and 50-pin D to 50-pin D from Videk (www.videk.co.uk). -- Pete Peter Turnbull Network Manager Dept. of Computer Science University of York

Ways to bounce a 1541

by spectre＠stockholm.ptloma.edu

Well, this is more a brag than something constructive, but I wrote my first automatic Commodore 1541 disk drive re-aligner out of desperation this weekend. I couldn't get it to read any disks and since this drive was the internal 5.25" in the 128DCR, I couldn't just replace it. So I wrote a program that commanded the FDC to whack the head into the restraining rail until it could read the disk again. Voila. ;-) The things you do when you're desperate ... -- ----------------------------- personal page: http://www.armory.com/~spectre/ -- Cameron Kaiser, Point Loma Nazarene University * ckaiser(a)stockholm.ptloma.edu -- Violence is the last refuge of the incompetent. -- Salvor Hardin -----------

Making an Atari 400/800 Basic cartridge Eprom type?

by claudew＠videotron.ca

Hi Anybody ever burn your own EPROM from a rom dump and just put it in a socket of a cartridge? I opened up a cart today to see a socketed ROM in there in only one of the 2 possible PCB locations for chips. I suspect 2 were used in some cartridges...not in the breakout game I opened today. Anybody know what eprom types are pin compatible for these if any? Claude

SMD cabling information / Symbolics know-nothings

by red＠bears.org

Derek Peschel and I are sitting here scratching our heads making confused noises trying to figure out why my Symbolics is broken. It worked (to a point) before I moved to this new house. Now it's not working even tot hat point. Power good. We can't get the FEP booted. I wonder if I haven't gotten the SMD disk hooked up correctly? At the drive end, there ar four possibilities for where to connect the 60-pin A cable, and two possibilities for where to connect the B cable. I have a terminator. We have wasted lots of time searching the web for this informaiton. How do I hook up the drive so I know it's connected properly? It's a 760 MB CDC Sabre 9720. Help! ok r. ps. Does anybody know enough about these machines to help me troubleshoot it? I think the basic parts all work, but just not yet together. It's a Symbolics 3650.

From: Richard Erlacher <edick(a)idcomm.com> >Has anybody got good logic analyzer pictures of the signals on the S-100 >driven by the really early 8080 CPU cards? I'm looking to get a reference Real simple start with a schematic of the MITS 8080 or IMSAI 8080 CPU card so you get to see how much buffering (mostly and only) and combinational logic applied to some signals (nearly none). Then get an 8080 datasheet, that IS THE TIMING for early S100. All of the later Z80, 6502, 6800, LSI-11, TI9900, COSMAC, 8085 and 808X to name a few boards tried to approximate that timing (before it morphed to IEE696) with combinational logic. Allison

Death by Poking

We lost a 19" Dell monitor (not cheap) at work last year when our Webguy punched in an unfortunate refresh rate and didn't hit test first. I wasn't there at the time, but my two buddies in IT who were in his cube (but facing away at the time) said the flash was impressive. > ALSO: Long ago in the Big Iron days... the were some machines in the > Philco line whose power supplies in some configs were marginally > inadequate. It was possible to load the machine (with programs and data) > and trip (or burn) the power units... I heard about someone who disassembled a "worst-case" memory diagnostic for some DEC machine with core, perhaps the PDP-8, perhaps some other 1960's model. He calculated that the program did not, in fact, perform a worst- case test for memory access/data loss. He described his ideas to improve the program to a Digit (DEC employee) who was familiar with the hardware and software in question. The curious customer was warned against implementing his idea because it was already known that a true worst-case scenario would result in too much current being drawn through the core stack, causing serious thermal problems if left to run for extended periods of time. Also, there were programs in the days if Big Iron to abuse hardware built with a particular duty cycle in mind, print hammers coming to mind. One I was told about by the perpetrator was simple and fiendish - he analyzed the pattern of letters on the band and devised a print line that caused all the hammers to trip at once, rather than the usual 10%-20% that fired when ordinary text was printed. The resulting current drain from a relatively small number of lines of this, fried the power supply. Then there's the practice of writing disk diagnostics that take advantage of harmonic oscillations when the drive's voice coil is slammed from inner to outer track, causing the drive to walk across the room. There are stories of this happening entirely due to heavy usage and disk thrashing, not just college pranksters seeing what the limits of physics are. Disks that weight one kg. and inkjet printers just aren't as much fun as the older stuff, one might think. -ethan ===== Even though my old e-mail address is no longer going to vanish, please note my new public address: erd(a)iname.com The original webpage address is still going away.
