I've updated my Wang 2200 emulator to version 1.1. It has been about six months since the last update. This release adds two signficant features: 1) disk support. You can now plug in disk controllers, each of which can control two drives. Drives can be any legal size, and the timing can model that of 5.25" or 8" floppies, or hard disks (even the interleave factor is modelled). You can optionally turn of the emulated timing and make it run as fast as possible. 2) when an error message is displayed on the screen (which are just two digit codes), double click on that line and a detailed explanation will pop up. the explanations come directly from the Wang BASIC manual. Adding the first feature was a lot of work. I started with the microcode dump from the disk controller and a document describing the microarchitecture (believe it or not, the 2200 has a 4b ALU and the disk controller has an 8B ALU). From there, I wrote a disassembler and studied the listing until I thought I understood the protocol. I implemented it and ironed the wrinkles out of my assumptions. Please have a look if you are interested.

Fwd: Canadian Collection

by dzubint＠vcn.bc.ca

*sigh* I wish there were more collectors out in Western Canada (I'm in Calgary at this moment...occasionally in Vancouver & Saskatoon) Whenever I search for old stuff (even just to look at and admire such as in a museum it's always in Ontario (or further east) which ends up being a two-day drive for me. There's been lots of PDP-11 stuff recently on ebay.ca, but it too is all in Ontario I'd LOVE to to see those Kenbak-1s...but they'r too far away. Oh well...

RCA Appnotes

by bkherbert＠adelphia.net

Dear Bob; I am puting together a history of low power systems and came across the RCA 1802 as maybe the earliest single chip CMOS processor (along with Intersil 6100). I am trying to figure out when the RCA ICAN-7029 appnote was written and wonder if it is in your Microsystems Manual or if you have other databooks.Thank you. Best Regards, Brian

Casio CFX-40 available - *brand new* or used

by scottmueller＠compuserve.com

Fred, Thanks for the heads-up. I do in fact still have a couple of *brand new* CFX-40s left for sale at $500 each. They are absolutely brand new, unused, never worn, in the original box, with manual and hang-tag. I also have *one* used CFX-40 in very good condition (it has a crack in the side of the case which has been repaired with cyanoacrylate glue), which is fully functional (everything works properly, including the light), has the original band, and which also includes the original box, manual and hang-tag for $300. For either new or used, add $10 S&H (incl. insurance). Email me directly if interested, I can send pictures and references if necessary, Scott.

9 track reel tapes

by cb＠mythtech.net

I came across a decent stash of 9 track reel tapes during my clean out. (4 cases, so maybe 50 or so of them) A while ago, I sold or gave away (don't remember) a whole bunch of the write protect rings for them. So I'm wondering, do those rings stop you >from writing, or enable you to write when installed? I want to try selling the 9 track tapes on ebay, but I want to make sure I specify the correct status of the rings (that don't exist). Also, are these safe to bulk erase with an electromagnet? So far none of them have any data on them that I am worried about erasing, so I'm not planning to bother... but I want to know if it is safe or not in case I find one I need to. And finally, are all 9 track tapes the same? These were used on our General Automation Zebra machine. So will they work on any machine that needs 9 track, or only on other Zebras? -chris <http://www.mythtech.net>

Casio CFX-400 LCD

by brian＠projectsst.com

Robbie, >From your e-mail reply to Stan (included below), you apparently have some knowledge of Casio CFX-400 watches. The display on my CFX-400 got wet and isn't displaying all the numbers correctly. I would appreciate it if you could e-mail me the contact info you have for Casio so I can get a new LCD for my watch. If you know anyone that has a CFX-400, I'd be willing to pay up to US$500 for a CFX-400 in good condition and up to US$200 for one that's not in working condition. Brian Scura...

Casio has four distributors that they send replacement parts to. None of them have the case in stock. The last time a case was sold from Casio was on April 30, 1996. It was to an individual, not a distributor. The CFX-400 case with key pad has two part numbers. The first is 73081910. It was later changed to 73081928, but it is the same part and description. There are two parts still in production and available from Casio that you may want to consider buying. They are the rubber backing seal and the LCD (not the module, just the screen). Good Luck.

hard drive advice requested

by jwest＠classiccmp.org

I finally started refurb on a drive rack, a nice low-boy HP 29425 with wood top. It's my first HP drive project that uses the 13037 subsystem, with a 7906 drive. This is so I can finally start going through all the 7905/7906 drives I have and figure out what works and what doesn't. After going over the drive very carefully with a fine tooth comb, checking all the power supply voltages, test point voltages, etc... the moment of truth - hit the load switch, then turned it off just before the heads loaded. Did this a few times to make sure the blowers sucked any stray particles up and to the filter before letting the heads load. Finally I let them load and got a nice clean (fortunately quiet) "drive ready". Which leads me to my question... In testing unknown drives and cartridges... one never knows if the heads will come out the first time and shred against the platter. I've never been standing around when a head crashes, but I envision horrible grinding noise as metal shards shoot everywhere inside the drive. Is there anything I can do other than visual inspection, before spinning up an unknown drive and letting the heads load, to help alleviate the bad possibility of a crash on a drive that probably hasn't been used in 25+ years?

TRS-80 printer cable length?

by tothwolf＠concentric.net

Does anyone know what the length of the original TRS-80 model 1/3/4 printer cable was? I am considering making some (some for my own systems, and a few to sell), but I don't know what the original length was. I'm also curious about the length of the model 2/12/16 printer cable, though I'd imagine it was the same length. -Toth

Les Objets book free for shipping

by vcf＠siconic.com

I ended up with a book in French that is of no use to me. The title is Les Objets and it's a book on object-oriented design. It seems to be the second edition and is copyright 1997. The ISBN is 2-212-08957-0. It's in near new condition. If any French-speaking (or otherwise) person wants it then it's your for the cost of shipping. Otherwise I guess I'll just leave it in my archive and wait for some French-speaking dude to come by my office who I can dump it on. -- Sellam Ismail Vintage Computer Festival ------------------------------------------------------------------------------ International Man of Intrigue and Danger http://www.vintage.org [ Old computing resources for business || Buy/Sell/Trade Vintage Computers ] [ and academia at www.VintageTech.com || at http://marketplace.vintage.org ]

PDP11/84 continued

by doc＠mdrconsult.com

After several hours with the 11/84 last night, it appears that I'm in the same boat as Gunther with respect to the Unibus terminator. First off, in *any* configuration with an M9302 Terminator in A-B of the last slot, the CPU hangs at boot at LED 77. I have plenty of G7273 NPG-grant continuity cards, as well as non-NPG knuckle-busters. Which they are. I'm pretty sure my configuration of the card cage isn't right. Here's the original layout (forgive any misalignment in the drawing - Mozilla apparently translates tabs to whitespace, and not correctly): A B C D E F || M7677 - 11/84 Monitor || || M8190-AE - CPU || || M8637-BC - 1MB || || M8637-DF - 1MB || || M8191 - Unibus PMI || || G7273 - NBPG || || M7860 General Dev Interface? || || M7860 General Dev Int. || || M7819 - 8-Line Async || || M7819 - 8-Line Async || || TCU-150 - Custom serial splitter, NPG unkn. || || M8526 - RX211 || || UniB OUT || M7258 - LP11 Printer Int. || The TCU-150 is entirely undocumented except for a couple of invoices for etching and assembly. It's supposed to be part of a system of splitting an available serial line into multiple comm channels, but that's all I know. For whatever it's worth, the original configuration map on the lid of the system unit is accurate, and appears not to have been altered, so I'd guess that the backplane is in its original state, too. What I want is some variation of this: A B C D E F || M7677 - 11/84 Monitor || || M8190-AE - CPU || || M8637-BC - 1MB || || M8637-DF - 1MB || || M8191 - Unibus PMI || || M7486 - UDA50-A || || M7485 - UDA52 || || M7521 - DELUA ethernet || || M8526 - RX211 || ...although the DELUA isn't strictly needed. Even without the DELUA, with the last 5 C slots populated with non-NPG grants or with G7273 NPG grants, I don't get a reasonable response from the RX02. And as I said, with the terminator installed, the box just hangs at powerup. Can anybody tell me what I'm doing wrong? Doc

Quick Basic

by r.mueller＠fz-juelich.de

When I wanted a copy of QuickBasic, not yesterday, but not so long ago, I was able to download it from the Internet. As far as I know Microsoft has released it for all to use. It is, however, not supported in any way. You can find the interpreted version on some versions of MSDOS; I believe DOS 5 contains it. What I got from the Internet was QB4.5 and a professional version 7.X. If it has ceased to be available I can send a copy if it has really been opened to public distribution. I must just find a set of diskettes. I know I have 4.5 but I am not so sure I can locate QB 7. If I get too many requests, I will ask those getting it from me to fulfill the condition of passing it on to others asking!!! Shareware=share the responsibility! Bob PS Warning; stay away from those versions of Visual Basic offered as free on CDs. I loaded one of these, it gave me NO WARNING as it told me I needed some components it would have to download from the Internet and then it dumped a bunch of junk on my hard disk, including substituting a new and unwanted "Desktop" and changed my Internet browser to something else, even less wanted than the new Desktop. Windows was never normal after that.

What's the problem with you guys??? The Unibus is really simple to get right. :-) One thing you should know about the 11/84 is that you don't use wire wraps on the backplane for the NPG slots in the CPU box. The M7677 (MDM) have NPG switches for all card slots instead. Go to that card and check it out... Second. The 11/84 must have a minimum load on both the PMI and Unibus. The minimum load module (MLM) is M7556. Since you have two memory cards, that MLM is not in. But depending on the configuration of the Unibus, you might want to have the MLM in there. However, I don't think you have a problem here, since I suspect that if the machine powers up, that aspect is ok. It would be nice to hear how Gunther is doing. I'm very sporadic on classiccmp though. If you need help on pdp-11 stuff, I'd recommend you post to info-pdp11, or alt.sys.pdp-11 (or whatever it's called).

The CPU is in slot 1, memory cards in slots 2 and 3, and the Unibus adaptor in slot 4. 5 and 6 are empty, 7 and 8 have the UDA50, and 9 has a printer card of some sort. For mine the NPG grant jumpers are actually on the bottom of the backplane. I have set them for where the boards are not. I had believed this system to be configured as working, but it is not. It has a second backplane but had no M9202. If I put the terminator in slot 9 of the primary backplane it hangs. I know the UDA50 needs the NPG out. I will have to examine to see if the printer card needs it or not. I would guess the Unibus adaptor would not?

HP 7914, HP 7908, HP 7911 for sale in Atascadero, CA

by ss＠allegro.com

Hi, I spotted three old HP disk (and disk/tape) drives indoors at a salvage yard (Heillman Salvage) in Atascadero, California(about 170 miles south of the SF Bay Area): HP 7914 HP 7908 HP 7911 They didn't look like they're in immediate danger of destruction (they're currently working on breaking up a Cray 2 ... no, they didn't have the entire machine ... apparently, the Computer History Museum got the CPU, and Heillman got most of the rest). The HP drives were a bit dirty, and I have no idea of the price. The phone number is 1-805-466-4893. Also spotted (outside): carcass of a Lisa (3.5" drive, no faceplate), a badly burned HP 9845, a probably stripped CE control panel for some 12 bit computer (no brand name visible, had a rotary dial with a semi-transparent plastic disk in lower-left corner of panel ... couldn't get close enough to read anything).

Hi, I received the following two-part email this week... A free 9835... ... I moved up to an HP 9835. [It's in Canada] ... Now the good news, I still have the 9835 in my basement. I think it's still close to being functional, it turns on without clouds of blue smoke but the monitor appears to have given up so no way of seeing if it is really booting up. I'm not sure about the tape drive? If you could locate a monitor, maybe you could get a functioning 9835. It's free to a good home And, the project: I have been looking everywhere for anyone who might have a functioning 9835/45 because I still have about 10 tapes with thousands of pages of HP BASIC that I would love to off load to some form of modern media in ASCII and translate into modern BASIC. If you could help me with this problem I would even pay the shipping of the 9835 to you, if you are interested? Anyone interested, reply (offline) to me, and I'll pass the contact info on to you. thanks, Stan

VAX 11/780 progress ... just a little

Hi, I'm still wondering if I'm left the only one actively messing around with a VAX 11/780, because all the help I get comes >from PDP-11 people ... but that's adequate since I am still debugging the UNIBUS. I now made sure the NPG line is interrupted under the M7486 part of the UDA50 adapter set. Now I no longer get a 3 on the M7485's LEDs but it properly goes up to the 4/5 blink. Even the port light on my RA90 lights up so that it feels like it's going to come up any minute. But it doesn't. The VAX console never shows any sign of life, the RUN light goes off and the M7485's LEDs show a constant 5 (no more blinking 4/5). Then the drive's port light goes off too. When I interrupt the console and UNJAM it says "HALTED AT 000007B7" The interesting thing is that I can set the R3 register (that indicates the device unit on the UDA50) to a different value (my drive is set as unit 0) and indeed the drive's port light never lights up, as it should. However, the machine hangs in the exact same way and when I interrupt it, it comes up at the exact same address 000007B7. Would that mean that we get stuck even before the boot sector is loaded from the disk? I have two straws of hope to hold on. One is that the basic diagnostics tells me that KA780 module M8230 fails. So I can replace that once I have a spare. The other hope is that my UNIBUS isn't properly terminated. I have what looks like a UNIBUS terminator card but whenever I plug that in, the UDA50 acts strangely and effectively never reacts to the host at all, just constant cycling pattern as if nothing ever happened. Also, my level 2 diagnostics fails when this terminator card in is. When I remove that terminator I see at least the UDA50 and host communicating a little as described above. And without terminator the diagnostics level 2 finishes flawlessly. How essential is the UNIBUS terminator? Does the missing terminator explain why the host hangs and silently stops during boot? I never get a machine check or anything. Or, am I just impatient??????? I do know from my other VAXen (6400) that they turn on all fail lights and make the drive's port LED go off during the first phase of the booting activity. Could it be that the VAX 11/780 just needs several minutes for this job? I don't think so... Who knows what the address 7B7 in Thanks, -Gunther PS: this is what the DUABOO.CMD does: EXAMINE SP ! SHOW ADDRESS OF WORKING MEMORY+^X200 G 0000000E 00000200 LOAD VMB.EXE/START:@ ! LOAD PRIMARY BOOTSTRAP LOAD DONE, 00004800 BYTES LOADED START @ ! AND START IT does that mean the VMB.EXE is loaded at 00000200, so that 00000747 is relative address 547 in VMB.EXE? Is there a commented disassembly listing for VMB.EXE somewhere?

A russian pdp-11??

by tponsford＠theriver.com

Hi All !! A good haul at the local University auction has netted me a coupla Sun Ulta2's, a few vt420 monitors an IBM3151 terminal and the neatest find in the last few months.... A russian pdp-11. It appears to be an exact replica of a dec professional 350. It has the same case as the decmate/ rainbow/professional series. All the labels, everything, is in cyrillic, but it is an exact replica of my 350, the only difference is that instead of the funky dec dual RX50, it has two ordinary looking 51/4 floppies, and the color is what my friend calls a soyuz silver or moscow gray, as opposed to the dec beige/sand. It has what appears to be a RD50/52 but it is all labeled in russian. It even has the CTI bus cage with the cards for the drives. On sliding the mainboard out, it is identical to my 350, except for a few oddities, and all the chips are labeled in cyrillic!. It dates from 1988 and seems to be in excellent condition, except for the upper plastic cover is missing the front plate. I was really tempted to fire it up, as it appears to have, an US style 110 power receptical. But second thoughts, made me cautious as I'm not sure of its electrical requirements and would hate to toast the power supply or boards as it is a bit different from the 350 in size and various connectors. If anybody has seen one of these or has info, I'd apreciate a little help!! In the mean time I'll did up my russian-english dictionary and maybe try to trans-literate the cyrillic characters. Cheers Tom Ponsford

TRS-80 rescue - help needed in RI

by classiccmp＠vintage-computer.com

I've been working on trying to get a pair of TRS-80 systems transferred >from Southern RI to sunny NorCal but I'm finding that the extent of the collection makes it prohibitively expensive to pack and ship (5 boxes of stuff from what I'm told). Is there anyone in the RI area interested in rescuing a TRS-80 Model III and a TRS-80 Model 1000SX (Early PC Clone)? There are peripherals (at least one printer, for instance) and lots of docs and software for these. I'm just trying to back gracefully out of the deal without leaving the donor hanging. I've belatedly realized that I can't justify the expense of shipping these relatively common systems from coast to coast. Please contact me if you've got an interest and I'll do what I can to set you up. Erik Klein www.vintage-computer.com/vcforum The Vintage Computer Forum

Remex Director Tape Reader Docs?

by ohh＠drizzle.com

Hi, all: Does someone on the list have documentation for the Remex "Director" paper tape readers (model numbers RRS9000 or RRS9006)? I've read manuals for other Remex models online, but not much of use for this one. In particular I'm curious about what effect the "spool/loop" switch has on operation, what kind of checking is done by the power-up self-check, and if there's some good sensible way to test the stepper motor driving the tape sprocket. If I can get some more data, it may save at least _one_ paper tape reader >from having a long and dusty servitude in a storage room. :) -O.-

HP 9835 avail; and: HP 9835 tape conversion request

by sieler＠allegro.com

Hi, I received the following two-part email this week... A free 9835... ... I moved up to an HP 9835. [It's in Canada] ... Now the good news, I still have the 9835 in my basement. I think it's still close to being functional, it turns on without clouds of blue smoke but the monitor appears to have given up so no way of seeing if it is really booting up. I'm not sure about the tape drive? If you could locate a monitor, maybe you could get a functioning 9835. It's free to a good home And, the project: I have been looking everywhere for anyone who might have a functioning 9835/45 because I still have about 10 tapes with thousands of pages of HP BASIC that I would love to off load to some form of modern media in ASCII and translate into modern BASIC. If you could help me with this problem I would even pay the shipping of the 9835 to you, if you are interested? Anyone interested, reply (offline) to me, and I'll pass the contact info on to you. thanks, Stan -- Stan Sieler sieler(a)allegro.com www.allegro.com/sieler/wanted/index.html

Old DOS on topic yet?

by rhudson＠cnonline.net

I would like to get an old single floppy DOS laptop machine on my local network. Anyone know how to get DOS to work with a PCMCIA card (uh too new?) It would be great to finally have this machine boot up as an emulated apple or PDP-8 or Atari or something. One of the floppyies makes it into a disk drive for my TRS-80 model 100 laptop. Ron.

Kenbak discoveries

by design.fort＠ns.sympatico.ca

Hi Jos, It was a pleasure to show you the Museum and the Kenbak :) I hope you had a nice vacation in Nova Scotia. I will eventually scan all the material and make them available for everybody interested in the Kenbaks. It will most likely be published on CD-Rom since it is a lot of material (especially the schematics). It will take a bit time since I do all this in my spare time. Greetings Herbert

Kenbak-1 discoveries

by design.fort＠ns.sympatico.ca

Hi all, I finally have more news from the Kenbak-1 front. Earlier this year I posted a message on this list that I discovered a Kenbak-1. Well as it turned out the source I had the machine from had 7 (!) more Kenbak-1s. After long negotiations we finally agreed on a price for the collection of 6 machines and incredible paperwork. (The seller wanted to keep one machine) After some more struggle to get the money together I finally purchased what I consider the "find of my life". Here is what I could acquire: - 6 Kenbak-1 computers - the original schematics (a big folder!) - original training films from 1974 and the early eighties. - an original sales flyer from CTI, a company that tried to market the Kenbak-1. - programming manuals, flow charts etc. I drove all from Nova Scotia, Canada to Charleston, South Carolina to pick the lot up. (3000 miles) More information about the computers, where they are from and most importantly photos of the Kenbaks are on my website: http://www.computermuseum.20m.com/kenbak.htm I currently try to convert the original training films. I'm also in the process of taking photos from the insides of all the machines. Those photos will be online within the next days. Four of the seven Computers have the original Kenbak-1 logo, the others the CTI logo. You will see that al of the computers have six holes drilled on the top cover. It turned out that the Kenbak-1s had overheating problems and the hole were the cure for that. One of the Kenbaks is slightly modified and has toggle switches instead of the push-button switches. This machine is the only one I have tested so far. It works perfectly. All I can say is that the Kenbak-1 is fun to work with! Greetings Herbert Computer Museum of Nova Scotia

Citizen's GSX-190 dot matrix printer

by cb＠mythtech.net

Anyone have a manual for a Citizen's GSX-190 printer? I'm trying to find out how many multi-copy pages it can support. I need a dot matrix printer that supports AT LEAST five carbonless copies (counting the original). Mac compatible is prefered, but I can deal with Parallel. I have an old Citizen GSX-190, and it supports underside paper feed, which I have found is usually a good sign for a printer designed to use multi-part forms... but I want to verify how many pages it is designed for before I go thru the effort of trying to get it hooked up (only to find that it looses grip on the pages just like my Imagewriters do, the Imagewriter is only designed to handle 4 copies max) -chris <http://www.mythtech.net>

9915A without tape drive

by vp＠mcs.drexel.edu

For those that have been claiming that HP always sold 9915s with a the tape drive installed, here is a picture of a 9915A WITHOUT a tape drive. Notice that it has a blank faceplate, not covers over the tapedrive slot. http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=3049594024&category=11175 **vp
