FA: Data General manuals, HP and Tektronix manuals, core memory, 3-axis acceleromer, Solaris

by rigdonj＠cfl.rr.com

I'm trying to clean out some of the clutter before the holidays and I've put a ton of stuff on e-bay including some core memory, a programmer's panel (both end in an hour. these are from computers that were junked before I found them), DG manuals, HP 9845 manuals, Tektronix programmable calibration generator manual, a 3-axis accelerometer, Solaris manuals, conductivity meter, and two NICE stepper motor drivers including one that's made by NEAT for driving optical stages. <http://cgi6.ebay.com/ws/eBayISAPI.dll?ViewSellersOtherItems&userid=rigdonj> Joe

You _do_ have to get the software images yourself, and install them somewhere. I myself keep "installation media" in the C:\DIST directory, and "disks" in C:\DSK. Everyone has their own system for that, I assume. Images of installation media are available from the archives, see http://simh.trailing-edge.com/ and the PUPS archive for some. --f

Simple C compiler advice?

by jpl15＠panix.com

Okey-dokey. I have now got all the nice SIMH packages stashed neatly away on the Trusty Laptop. Obviously, they must be compiled. In terms of software, I am an appliance operator. I have had very minimal experience with C programming, mostly in the 'hello world' levels of complexity, and that years ago. Therefore, what would recommendations be for a simple, cheap/free, plain old C package that I could use to compile these simulators? I understand the basic idea behind the process, but it's been many years since I compiled anything, save for the tiny Fortran demo program in the RSX11M docs... I am not going to use it for 'real' programming, just to make a PDP-faux-11 on my Wintel Lap-Puter. T I A John

Altair32 Emulator

Sellam: >On Fri, 15 Nov 2002, John Lawson wrote: >> Thanks again... certainly an wonderful example of what this List is >> for... >All the more inspiring, considering Richard learned how to program C >through this project. >(Is that right, Rich?) Yes, this is true. If you look in the ZIP file for "building.txt" I give a little background on how I got involved. To sap some bandwidth, here's the Readers Digest version: By day, I'm a banker. By night, a closet programmer. I came across the binaries for the original emulators about three years ago. Since I have no expectations of owning a real Altair, I thought that it would be great to use an emulator. Well, the original implementation didn't work. About two years ago, I found the source for it on the Web. I contacted Claus Giloi and he basically said that he didn't have time to improve it or actually verify that it worked. For him, the project started in 1991...the last build was done in late-1996. Claus built the emulator from the magazine article and the data books -- nothing else. He had no software or a physical Altair to work with. The original emulator supported nothing...no disks, no console, no way to get programs into or out of it. The CPU code was about 80% functional, but it's the old "80/20" rule...the last 20% was the hardest to fix. Basically blinkenlights and nothing else. My total programming experience for years was limited to BASIC, VisualBASIC and 6502 assembler (on the Commodores). For pleasure, I had already read all of the Andrew Schulman "Undocumented..." and "...Internals" books, so I was familiar with what was going on in a Windows program (from the inside), and there were plenty of C code examples to read, but like any language (programming or other), it's one thing to read it and another to write it. So, since Claus gave me the go-ahead to take over the project, I jumped right in, and the first mods were done on June 8, 2000. So, not only did I have to learn the syntactical nuiances of C, but I had to learn the intricacies of Windows programming and emulator writing, in addition to noodling around code written by a professional developer working for Microsoft. I'm still lousy at C, and I wish I could take an "Adult Education" class on it. Anyway, that's the story.

Is there any kind of fuse in these >machines or is it probably dead. Check the PRAM battery. Many of the Mac models with soft power won't boot without a good PRAM battery. It need not read the full 3.6 volts, but anything less than 1 volt is no good. The battery, oddly enough is available as a regular stock item at Radio Shack (yet similar PC CMOS batteries are not... go figure). Also, the 550 models are soft power, but also have a hard power switch on the back. Make sure the switch is on, and then hit the power key on the keyboard to actually power it up. Just flipping the hard power switch on the back won't let the mac boot (but will usually result in a quick electrical pop noise as it charges up, if the mac has been idle long enough). -chris <http://www.mythtech.net>

Broken SIMM tabs on Mac IIci

by bob_lafleur＠technologist.com

Ok, so I did it... When trying to remove the SIMMS in my Mac IIci I broke some of the little tiny plastic tabs, so now the new SIMMs won't lock in. Is there some "fix" to get the SIMMs to stay in, short of soldering new sockets into the board (which I am not about to do)? Also, I broke them on Bank A. I assume you can't use RAM in Bank B without having Bank A full... Should I just trash the motherboard? Or can I salvage it somehow? Are these SIMM tabs particularly vulnerable, especially on this old equipment? I broke them on 2 machines, and on the 2nd one I did, I was trying to be very careful. - Bob (not a happy MACer today)

65C51 Stock?

by per＠tdsi.co.uk

Hello Ross, The 65C51 seems to have gone obsolete and I'm looking for stock of the Rockwell 65C51, or equivalent. I saw your name mentioned in a reference on the 'net about supply of 65xx series IC's and wondered if you've got any contacts who might have 65C51's available. I've made other enquiries through the trade, but they are all a bit hit-and-miss and I thought you might know what the present situation is with these devices.

Even using the REPT key to workaround the codebar issue, I wasn't able to connect the carriage problem conclusively to either a rotational or a vertical problem. I think at this point I'm going to take the carriage off again and try a more thorough dismantle/clean/oil. Once I resolve the codebar issue it will be easier to diagnose the carriage problem with a clean mechanism. >This tells me it is something sticking in the linkage that goes >between the code bars and the print head( or he has it installed >wrong but that doesn't explain why it starts working with repeats ). >I would remove the print assembly and put it in some solvent >while moving the levers.

So I'm inclined to think that the magnet is just responding to what it is receiving which is incorrect. I cleaned the distributor and reseated the brushes, readjusted the brush holder to the alignment mark per the adjustment procedure in the manual. So I'm back to option 1) - the keyboard - as the source of the problem. One thing I noticed last night was that the keyboard cover is broken. There are four round tabs, one at each corner, that fit into corresponding holes on the end plates. These are broken, so the cover can rock from side to side, pivoting on those center projections. I wonder if that could cause some sort of alignment problem within the keyboard ? Thanks for the suggestions - I will get to it again tonight and see what else I can find out.

Discovery Computers 4 Sale

Curt, >Discovery Computers??? x86 multiprocessors??? Please elaborate, any links >or picks??? Discovery was produced by Ace Computer Action Enterprises, Pasadena, CA., c. 1983. It came in at least two models, as documented by one Bill Whitson in The List in '97. ACE Discovery 500 83 Discovery 1600 83 I have one Discovery 500, sans disk drives (one floppy, one MFM 20 gig [whoops, I mean meg :)]. I also have one Discovery ????, which is likely a slave unit - having no provision for disk drives (but does have a SemiDisk for some healthy memory). This is about as much as I know ('cept one of these ran a BBS back in the olden days, if memory serves). Don't find much documentation. But also, I haven't checked the Computer Museum of America, here in San Diego, except to ask if they would like to have them. They already have one, hope they will take one or both for parts or.... However, I'd be just as happy to see them in use by someone who has time and energy to make them go.

Dying VaxStation 4000 VLC - help?

by mtapley＠swri.edu

All, More info: >Linear Technology 1.5A adjustable voltage regulator, TO-220 package. Has about the same voltages on its pins when the system is either running or failed: Vin 5.4V, Vout 3.5V, Adj(gnd) 2.1V Should that last be 0.0? I'm referring all of these measurements to Chassis ground, obtained by wedging a lead against the power supply housing. Measurements power-off with the Ohmmeter say that last pin is about 75 Ohms away from Chassis. Ironically, that's more than the readings for either Vin or Vout. >Low Power Low Offset Voltage Dual Comparator (LM193) This guy is intimately linked to the failure. V+ connected to 5.4 V (Red wires) Gnd connected to ground (Black wires = chassis ground.) Output A obeys the following rule: running fail out A 5.4V 0V One other interesting thing is that the first few times I touched "out A" with the probe, it failed immediately. I actually *did* get to see the needle swing a couple of times, as it tried to decide whether to run with the probe on that lead. Eventually it decided to run even with the probe on the output. The meter claims 20,000 ohms/Volt DC, so I did not expect to crash the system by probing it. I tried Out B, but it didn't change while I was watching and I didn't record what state it was in. Thermal dependence is still flaky, but it did go rapidly and persistently toes-up when I turned the hair-dryer + funnel combo on the LM193. I only got to do one trial, though, before it got to the point that it wouldn't run long enough to convince me the heat gun was doing the deed, so that could have been coincidence. I tried a few other parts of the circuit board, and got similar results out of a big chip near the SCSI connector. Dunno if that's relevant. - Mark

Broken SIMM tabs on Mac IIci

If you still have the broken pieces, you can probably glue them back on with a solvent-weld plastic cement such as Tenax 7R.

CPM-8000

by dwightk.elvey＠amd.com

Hi I've just sent my latest CPM-8000 stuff to the unofficial cp/m site. It is available under: http://www.cpm.z80.de/binary.html It has a working boot image plus the other files to run this on an Olivetti M20. It does have code to regenerate a new BIOS so that it can be ported to another Z8001 machine. If anyone is contemplating this, they should contact me or Chris to help out. There are a few things that effect hardware that one should know. It would also be very difficult to complete the job without access to a M20. I am willing to run compiles on my machine for anyone that writes their BIOS to create a working image. Thanks to Hans B Pufal, Gaby Chaudry and Al Kossow. Without there information, I wouldn't have been able to begin to get things working on the M20. Of course, 50% of the credit goes to Chris Groessler, as we collaborated on working the bugs out of creating the first boot images. Dwight

Beginner's Supnik Emulator help

by jpl15＠panix.com

I downloaded E11 some years ago on a Pent I desktop but never got it to work, prolly due to no smarts on my part. This evening, thinking it might be fun to hook up my M4 Data SCSI 9trker to the laptop, and use it to work on Stuff to be transferred to the 11/44 later, I DL'ed the latest and greatest from his Site (V3.1), and installed it. I am running Win 2000 on an IBM A21m Thinkpad, with 256M of RAM and a 10GB HD. Right away, my little Pest Control program flags me that 'ntvdm.exe' has been detected, and as many times as I exterminate it, it returns as soon as e11.exe is run. Is this a bug, or something in E11 that looks like one? The details say it is a VBB virus tutorial... if it *is* a virus, or virus-related creepy-crawly, then there are much bigger problems afoot and I'll scrub the whole thing. At the E11> prompt in the DOS window, I type: E11> set cpu 44 E11> mount du0: rsx11m ERROR opening file - RSX11M.DSK E11> mount du1: ra80 ERROR opening file - RA80.DSK And so on... each iteration brings up the virus warning, and the disk emulations seem to be AWOL. So: any ideas? Obvious Stupidities? etc? Cheers John

Broken SIMM tabs on Mac IIci

Then treat the mended sockets with extra care, as they will never be as stong as they were originally. >> why not just use hot-melt glue to keep the SIMMs in? At least you could remove them later.

Big computer "scrap" cleanup in Washington, DC

by wh.sudbrink＠verizon.net

I just found this by accident: ============================================================ Junk Collection on Monument Grounds Updated: Friday, Nov. 15, 2002 - 8:02 AM EDT. (Washington) -- Got an old computer that's taking up space? How about a TV that's seen better times? Friday and Saturday, you can bring your old electronics to the grounds of the Washington Monument to be safely discarded. The event is a joint effort by the White House, the District, and the EPA. Environmental experts say some old electronics contain lead or other materials that can potentially harm the environment if they're not handled properly. Computers, telephones, office equipment, and some televisions will be accepted. But no luck if your TV is larger than 19 inches or encased in a wooden console. Kitchen appliances, microwaves, vacuums, and air conditioners also can not be turned in. (Copyright 2002 by The Associated Press. All Rights Reserved.) ============================================================== Now, granted the stuff that shows up will likely be 99% real junk (386 Wintel boxes) but is anybody in the area going to try to snag any of the 1% gold that may show up? I wish I had known about it sooner, my weekend is booked solid. Bill

Altair32 emu and VanDyke CRT fix

by jpl15＠panix.com

Using VanDyke's CRT telnet client as a 'console' for Rich's Altair Emulator, I find that I have to configure an option to make it play nicely: In 'Sesion Options" "Connection" "Telnet" [X] Force Character at a time mode That seems to have made it work well... and the launching sequence is critical, as laid out in a previous message...

Found Altair problem:

by jpl15＠panix.com

Turned the damn firewall off. Should the CP/M disks just have one file each? Like PIP.COM on the CPM22 disk... This had no effect on Ersatz-11... it still is unhappy with me for some unfathomable reason... Cheerz John

ANN: Altair32 Emulator version 2.40 released

by rcini＠optonline.net

Hello, all: Tonight I posted the latest release of the Altair32 Emulator for Windows. There have been a few changes since the last release in August. Working closely with Scott LaBombard, we've added configurable memory ranges (split between RAM and ROM), a ROM Manager to allow the easy adding or removing of ROM binaries, and selectable console terminal using telnet or the Windows Console. Scott also generated new CP/M 2.2 disk images from the 2.2 source. He also re-wrote the CBIOS to fully enable 8 emulated disk drives, including up to 4 "large" (1.1mb) disks. Finally, in an effort to improve performance and reduce CPU utilization on the host computer, I made the conversion to a timeslicing model based on Jim Battle's Solace project. Enhancements on tap for the next release include a toolbar, a tabbed configuration dialog, and VT100 control code support within the Windows Console code. You can visit the project page at http://highgate.comm.sfu.ca/~rcini/classiccmp/Altair32.htm to download the latest ZIP file. Thanks and enjoy.
