It seems that someone with a little cleverness could write a simple mouse program that would digitize mouse movements and buttons. It was a while back but I used to hand fix bad gerber files to get PC boards made. It seems that most programs still have bugs and will trash some of the commands. I'd display the gerber file on the screen and look for the big trapezoid or some other messed up thing. I'd then go in and change it back to the correct rectangle or what ever. It has been a number of years but like I said, it wasn't that complicated. You need to consider that is was a direct input sequence of moves for a gerber plotter. Dwight

Zilog System 8000 Model 31 available in Australia

by xds_sigma7＠hotmail.com

The System 8000 is not really a development system... They are full-on minicomputer-type UNIX machines.. It's a so-called "Super-micro"... I am holding an ad from the DEC Professional proclaiming that the sucker can run DIBOL... I really have to wonder if anyone ever ported DIBOL to any system besides the System 8000, I wouldn't think there was enough of a user base to justify doing such a thing... Anyway, it is a Z8000-based UNIX minicomputer (yes I'm aware my definition of minicomputer may vary from some listmembers). Someone should save it! It's freakin' cool...

Cheap PCBs

by gil＠vauxelectronics.com

Hi Jim: I'll second that vote -- Advanced Circuits (www.4pcb.com) is a great place. I have done many boards there, proto and production. Quotes, and order status, is online 24/7. But I think they only take gerber cad files. Back to the original question: I'm not sure how to do a non-gerber board inexpensively. If the artwork is in a pdf file (or even a tif from a scan), you would need to find a board house that could use it, but none come to mind. To make it yourself, you can print the pdf to lino film and make a board using sensitized board material from kepro, then etching, immersion-tin dip... Sheesh, I did a lot of those years back. Even the best homemade etched board is shitty though. And you can't cut corners on the pricey lino film. Transparencies from an inkjet or laser may look good, but the black is not opaque enough for uv exposure. Board material and chemicals are not cheap either, so it gets pricey, and you still end up with a pretty crappy board. There is some laser printer material that you can print and then iron onto a bare copper board (then etch), but I have never used it. Can't imagine you could reliably use small geometry. But the cost is now just a cheap plain board, the laser material, and some acid. Maybe an aquarium heater to speed up etching. For a one-off board, and if the board is simple and just needs fat traces (this capacitor board may well be), you can also simply get a bare board, drill component/mounting holes, and isolate the "traces" but cutting through the copper appropriately with a dremel or xacto. You can even use double-sided material and isolate the upper ground plane with a small countersink at the component holes. I have also found a that a roll of adhesive copper tape can be very handy in times like this. gil >From: "Jim Kearney" <jim(a)jkearney.com> >To: <cctalk(a)classiccmp.org> >Subject: Re: Cheap PCBs >Date: Wed, 20 Nov 2002 18:32:55 -0500 >Reply-To: cctalk(a)classiccmp.org > > >For only a few dollars more, you can get more boards with solder mask and >silkscreen. www.4pcb.com will do boards up to 150 sq inches for $33 ea in >quantity 3 and up, including mask and legend. www.e-teknet.com does qty 4 >up to 55 sq inches with mask and legend for only $22.99 each.

Altair32 Emulator

by RCini＠congressfinancial.com

John: The way the telnet server within the Altair32 works is that it's activated upon the "first" access of a CPU I/O port by a running program. So, for example, if you are running a program that doesn't interact with any of the console I/O ports (0/1, 20/21 octal), the telnet server will not be activated and any telnet client will bomb out, complaining that no server is found. So, the sequence I use is to run HyperTerm and "disconnect" from the telnet port (UDP port 23 by the way -- the standard telnet port). Then, I run the emulator, attach disks and "boot" CP/M. I run ZoneAlarm, so I get a notification that a telnet server is starting (with a TCP address of 127.0.0.1), so I allow the access then "connect" HyperTerm. If you don't run ZoneAlarm, you just have to guess the timing when connecting. When booting CP/M, it's no more than a few seconds. If you look at the front panel address LEDs, you can "see" that it drops into an idle loop (the address LEDs appear to only reference a tight range of addresses). This is the signal that the CBIOS is waiting for a "live" connection. If you prefer, you can use the built-in Windows Console. That doesn't have the same connection problems as telnet. With telnet, however, you should be able to reach your Altair across a subnet (although I've never tried it). The disks are full with stuff, and there certainly should be more than 2-3 files. The CP/M 2.2 disk probably has 25 files on it. Rich

osi dbi info needed

by n8uhn＠yahoo.com

Found the problem, the +5 volt line on the siemans 8 inch drive is shorted - causing the power supply to shutdown. also i inserted the cpu boards (yes two of them) backwords(the osi backplane slot headers are not keyed)(joy, more rebuilding). i am really interested in info on "d & b computer systems" did they make more then clone boards for the osi systems? does anyone have the dip switch tables for the two banks of switches on the dbi cpu boards. the boards i am looking for info on are the dbi db1 (cpu mem and console board) and the d&b db-pfdco1 (fdc/comms board). the fdc board has a 50 pin header for the floppy's but also has a 40 pin header below it. can a 5-1/4 or 3 1/2 floppy drive be interfaced to a osi system? also what is the pinout of the osi/siemans fdd-100-8 e interface connector? it seems to be almost the same as the shugart 50 pin - but how does it work with the read data pin not used in the interface?

Varieties of Lisa/Early Mac Mice

by jingber＠ix.netcom.com

I'm trying to gather information about the different varieties of Mice that were used on Lisa and early Mac systems. I'm looking for additions/clarifications to this list, specifically which mouse would have been shipped with which system, and if mouse #2 ever existed. Jeff -- #1 - Original Lisa Mouse (Lisa and possibly early Lisa2?): Had a metal ball, long rectangular button, and a "clip"-type retension mechanism on the connector. The mouse port on the Lisa did NOT have metal around the connector as is common on DB-9 female connectors. Instead, there was a plastic "lip" to which the retension clip on the mouse would mate. The bottom of the mouse was sloped and did not have a sharp angle like the M0100 mice. The mouse had a tan colored cord. #2 - (Early Lisa2?): Same as #1 but with standard DB-9 connector instead of the clip-type retension mechainism. Each thumbscrew had an Apple logo embossed at the ends. #3 - Early M0100 (Possibly later Lisa2/Mac XL): Button was not as slender as the Original Lisa Mouse and had a standard DB-9 male connector instead of the clip-type retension mechanism. Each thumbscrew had an Apple logo embossed at the ends. Both the button and cord were tan colored. #4 - Later M0100 (Apple II?): Same as Early M0100 but had a gray button and cord instead of the tan button and cord. The thumbscrews did not have the embossed Apple logos and were somewhat thinner. The internal mechanism was also slightly different than the Early M0100 and are not interchangable.

DG Nova 3 Repair Advice

by univac2＠earthlink.net

Among many, many other projects I need to tend to, I am working on finishing up on my Nova 3 restoration project. The last thing I need to do is replace the burnt out incandescent light bulbs on the front panel. I wanted to replace them with LEDs, but white ones cost $4.99 a piece at RadioShack. Plus, I'm betting that the bulbs take enough power to blow out an LED. RadioShack doesn't seem to have the exact kind of bulb that is on that panel. So, might anyone be able to tell me what kind of bulb I need to get to replace the bad ones, or how I might be able to use LEDs instead, which I would prefer, as I don't want to be replacing burnt out bulbs all the time. -- Owen Robertson

If both have a monitor, it uses VGA (I wasn't able to get it to work with both at the same time... maybe if I had docs and knew what the dips did). The interesting thing with mine is it is one of the few cards I have with a "Slot 8" jumper, which if I understand it right, was to let you use it in an XT that had slot 8 reverse wired (or something to that effect). -chris <http://www.mythtech.net>

Convex Supercomputer

by cmcnabb＠4mcnabb.net

Here are some responses to a question I asked of the people-who-who-would-know about the Convex C210 that is currently on Ebay. It looks to me like the machine hadn't been used in quite a while. Also, It doesn't look like the power cable assembly is included. Also, it seems that the machine was NOT in use in Oct of this year, regardless of what the Ebay blurb says.

A tale of two Osbornes

by gil＠vauxelectronics.com

Hi Lawrence: I expected a keyboard problem, since the owner said it had a stuck key. Sure enough, the boot screen would flash as if you were holding down an incorrect key. When I opened it up, the row and column flex connectors were plainly visible. Also, the keyboard pinout is in the tech ref (which is online, if you don't already have it). I peeled a corner of the flex circuit up off the aluminum plate, and could see metallization crossovers where the shorts likely exist. I could punch a hole at the crossover to break the short, but then I would need to jumper the cut traces. And this does not look like a solder job -- liquid conductive ink perhaps? There could be shorts in the middle of the key array too. The keyswitches are plastic, with posts that protrude through the mounting plate, and then melted into place. All in all a nasty thing to even think about repairing. Perhaps I am on the wrong track (no pun intended), but I pulled the two flex connectors out, so the ribbon cable is not connected -- I can measure many shorts right at the flex terminals. All of the melted-in-place keyswitches would need to be removed to asses the situation properly. Bummer. At least I have a new keyboard I can plug in. I have not opened that one up, so I don't know if it is different. gil > Uh-Oh ! I picked up a beige Osborne 1 last summer. It's in my >lengthening To-Do queue.

Its job is just to make sure the voltage-divider tap comes up slower than the voltage reference?

Dying VaxStation 4000 VLC - help?

by mtapley＠swri.edu

All, I didn't get around to the soldering last night. My wife informed me that we were going to get up at 0400 so the kids could see the Leonid meteor shower, so I decided to get to bed earlier. Glad I did, it was spectacular. I did do some more probing around the mainboard. >> <88W>...I'll probe around looking for a resistor connecting high end to +5V. I looked. It doesn't connect to anything nearby, and when I say "doesn't connect" I mean completely open circuit to everything. Practically every other connection shows at least *some* conductance to *something*. Also, I noticed that the other pins from SMD's like this one have a little trace running off to a microscopic little pit in the printed circuit board. I assume this pit is where the conducting path dives into the innards of the circuit board. There's no such trace and pit on the upper right terminal of this device. I think it really is a no-connect. On the 6192: I misled you all, I think. My apologies. Although I remembered the color as "orange", it's in fact a subdued burnt orange, in contrast to the bright international orange of the tantalum capacitors. Someone who didn't graduate from the University of Texas might reasonably refer to it as a reddish brown. :-) Meantime, there is in parallel with it, just as Tony predicted, a tantalum capacitor (bright orange, with a pip). One more piece of evidence: all the tantalum caps have, in addition to the pip, a "+" printed on the circuit board near one end. There is *one* exception to that, where the pip points toward the power supply and away >from the "+" on the PCB. It's over near one of the connectors on the back edge (maybe the SCSI, or 25-pin serial? I forget, but will post good directions if anyone wants). The "+" mark is not present on 6192's position on the PCB. 1) Anyone with access to a 4000 VLC mainboard, would you mind checking and confirming that *all* of the tantalums are supposed to have the pip near the "+" (and hence one of mine is probably in backward)? Or wait for better directions, and check just the one that's backward on my board? 2) What's the consequence of having it reversed? Is that cap. probably now dead? Anyway, by now I'm pretty convinced 6192 is the lower resistor of a voltage divider. I did not find a feedback resistor for the comparator. It still could be there, but I don't think it's very close by. - Mark

A tale of two Osbornes

by gil＠vauxelectronics.com

Hi folks: I recently got two Osborne 1 computers. The first one (blue case) had a dead power supply -- I fed +5/+12 DC power into the battery connector and was able to bring it to life, but had no software to test it further. This one has a double-density option board inside (and drives I presume), as well as the optional modem. I also got a second osborne (early beige case), which came with software and manuals. This one has a keyboard that seemed to have a stuck key. Turns out that the keyboard matrix has many shorts, not only row-to-column, but also row-to-row and col-to-col. It is a flex-circuit soft of design, and it appears to have a silk-screened or deposited metallization pattern for the matrix. There is an insulating layer of some sort and then a second metal layer. Anyway, it seems that the insulation between layers has failed where some traces cross. It'll be a mess to fix, if even possible. Anyone else have this problem on an early keyboard? So I plugged the later keyboard into the early unit, and was able to boot cp/m. I tried to copy the original cp/m disk to a new one, but copy had read errors on a couple of tracks. I could see some visibly-crappy spots on the disk surface too, but it did boot fine, and the utils seemed to run ok. So I formatted a new disk, copied just the system, and then pip'd the files over. Hmm, no errors on file reads with pip -- does that make sense, since copy previously found bad tracks? After booting and running off the new disk, it seems that all command files are working, with the possible exception of movcpm (which seems to hang the machine, though I am not sure how it works). So I finally got the original disks copied, and learned a bit about the machine in the process. I fired up the later (double-density) model, but it would not boot from the single-density disk. Should the DD drive be able to read the SD disk? The drive was making an odd noise, so it may be drive-related. Is there a way to boot from drive B? Can I swap the drives, and if so are there master/slave jumpers, or terminations that need to move as well? On the early machine, there was a diagnostic mode in rom (ctrl-D at the boot screen, I think it was), but the newer unit does not respond to that. Were diagnostics removed from later roms? I swapped the working power supply from the old unit into the new machine (yes, I know about the different jumper/harness connections). It worked fine. Then, I put the non-working power supply into the early unit, and it started working! I think the original power supply problem in the newer machine may have been an intermittant in the fuse/voltage-selector gizmo, which tells the PS whether to expect 115 or 230 -- in the early unit, this gets hard-coded by the jumper wire on the PS board. Crazy frickin' computers. Then I accidentally cracked the brightness trimpot on one, as I put things back together. Tacked a temporary pot in place while I look for a replacement. I shouldn't try to do this stuff at 2 in the morning, I guess. Well, that was sort of an FYI ramble, but any thoughts appreciated. Does anyone have double-sided software for sale or trade? thanks, gil smith ;----------------------------------------------------------- ; vaux electronics, inc. 480-354-5556 ; http://www.vauxelectronics.com (fax: 480-354-5558) ;-----------------------------------------------------------

SOL-20 / eBay prices

I'll give him the benefit of the doubt and assume he doesn't realize that the TV is meant as a display - he probably thought the PL-259 video connector was to attach a boat anchor or some other exotic accessory. It seems that a lot of the tech stuff on eBay is sold by people who are *completely* non-technical - I stumped one seller by asking him what card an Apple 3.5 drive was attached to - he had trouble "tracing the wires". Doh! Ben P.S. I read in the CCTalk archives that you had Bob Marsh as a previous VCF speaker .. did you ever put a transcript of his talk on-line, or maybe have a recording of it available?

VAX 6000-410

by pat＠purdueriots.com

There's one that I just saw get unloaded a few minutes ago at Purdue University Salvage. Looks to be in good condition... except it's laying outside on its side since they regard big things like it as 'junk'. Well, if anyone's interested and nearby, drop me an email and I'll get you more details. Unfortunately, I don't think it'll last too long outside - they may end up dumping more stuff on top of it, or mother nature may end up dumping stuff on top. I would get it myself but I don't have any way to get it, let alone somewhere to store it.

Acquired some Nat Semi ICM-3216 systems

by classiccmp＠crash.com

As mentioned, I just picked up some new machines in Canada... A gent had saved some National Semiconductor ICM-3216's from a university lab and was glad to find a new home for them. These are fairly full- featured little systems designed to showcase NS's 32000 family, with on- board serial and parallel ports, a SCSI controller with it's own Z80 to mind the bus transactions, a modest expansion bus, etc. Since these were board-level products, everything else like cases and drives had to be built or found elsewhere. Two of the hosts I received were timesharing systems and are housed in nicely designed cases custom built from sheet steel. A third timesharing host has gone elsewhere, and a fourth ICM was later built in a PC/AT clone case where students could try coding on the bare metal by booting from a SCSI floppy drive. One of the timesharing systems powered up and ran just fine before loading for the trip South. The icing on the cake was an unexpected trove of manuals that originally came with all this stuff, including full schematics for the boards, and two (binary) versions of SysV Unix on QIC tape. I'm still sorting through all this stuff, which includes a folder full of notes, letters, and some brochures for different components like disk drives and terminals, mostly >from 1986. Eventually I expect to get some pictures up, and depending on where VCF East is I think I'd bring one along. --Steve.

Paperwork to move classiccmps from .ca to .us?

by classiccmp＠crash.com

A while back I'd asked for tips on moving machines from Canada down to the US. Thought I'd answer my own question now that I've done it. The gentleman giving me the systems (details to follow) wrote me a note stating that they were obsolete, over 15 years old, and that any commercial value was less than $100. It also stated that the machines were a gift rather than a sale, which was the case. It looked like the US Customs agent wouldn't have bothered asking, but I mentioned the machines and handed her the letter. Had it been a trailer-load rather than a couple boxes in the back of the SUV, it might have been different, but as it was she just waved me through. --Steve.

SOL-20 / eBay prices

by benb＠Basit.COM

Actually there's two SOL's currently on eBay. The 2nd one is currently "only" $500 or so: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=2071406461 The difference being that it has no documentation (which I suspect accounts for the price difference), and also it only has a single card in it - a non-PT 64K memory card (I asked the seller if it was PT or not). In recent history SOL's have sold for anywhere from $490 to $2500! Documentation also seems to be what has so far driven this Altair to $4K: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=2072033128 Ben Glen Slick wrote: >At least $1500, ending today.... > >http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=2071171983 > > >>From: Sellam Ismail <foo(a)siconic.com> >>Reply-To: cctalk(a)classiccmp.org >>To: <cctalk(a)classiccmp.org> >>Subject: Re: Whats wrong with chip collecting? >>Date: Sun, 17 Nov 2002 14:04:53 -0800 (PST) >> > >>I suggest the former.
