PC/AT power-good troubleshooting
by Richard Cini 28 May '16

28 May '16

All – I pulled my old PC/AT off the shelf to see if I could get Windows 1 running on it. It worked when shelved years ago, but it unfortunately suffered some case damage from a leaky battery. No damage to the mobo or cards thankfully. I replaced the battery with a 4-AA pack. Basically, the PC won’t come out of reset. I tested the power supply with a load tester specifically for PC power supplies and it reports power_good and all voltages look good on a meter. So far, so good. I dug out my ISA POST diagnostics card which also has a PG tester in it. This reports no_PG but I do see the reset pulse. Not sure why one would report OK and one not. I traced the PG signal from the power supply through the 82284 clock driver/ready interface chip and the PG is definitely there (transitioning L->H on power-on) and RESET is transitioning H->L. I have a spare power supply (which also tests good) and produces the same result. I have no cards installed, nor any other load on the supply (floppy and hard drives disconnected), so it purely has to be an issue with the motherboard. Any recommendations on where to go from here? Does anyone have an extra AT motherboard they would be willing to part with? Thanks! Rich -- Rich Cini http://www.classiccmp.org/cini http://www.classiccmp.org/altair32

Not too many years ago, a friend found a Cray 1 that was stored in someone's garage and made a deal to buy it. Before he even took possession, he ended up trading it for an Apple 1 when he realized he didn't have a place to keep it. Who knows, there could be a few more out there in the wild. Not so many years ago, it was estimated that there were only 30 Apple 1 's remaining. New units keep surfacing every year. Regards, Mike Willegal

ADTPro help
by Evan Koblentz 25 May '16

25 May '16

I last used ADTPro about a year ago. It worked fine. A few months ago I installed a new mobo/memory/processor in my daily PC (still running Ubuntu). Yesterday I tried ADTPro again and got this error message: "There are no serial ports, or the serial library RXTX is not installed or visible." Paul H. suggested that the adtpro.sh file was looking in the wrong place for RXTX. Made some tweaks but it's still not working. Note also that ADTPro has its own copy of RXTX in a subfolder. Stephen E. also tried to help. Can someone who is experienced at both ADTPro and Linux (and who has the patience to walk me through this) help me, please? Hoping to get some help via telephone or Skype today/tonight if possible.

A more efficient BBS Xfer protocol
by John Heritage 25 May '16

25 May '16

Hi folks! Being a geek and SysOp I spent a lot of time as a teenager looking for the most efficient BBS file transfer protocol - working through XModem CRC, Ymodem-1K, ZModem, ZModem with MobyTurbo, Ymodem-G, etc.. I even ran HS-Link (and BiModem) for a while to help people who actually uploaded to BBSes :). In search of CPS, the fastest I could transmit a compressed file over a 14.4 kbps link (1800 cps theoretical maximum) was using Ymodem-G** with a series of modem settings (AT&K0 - disable compression, and a few others), achieving just over 1730 cps. ZModem* was something in the 1630-1650 range, and DSZ's "mobyturbo" Zmodem would do ~ 1660-1665. Anyway I had an idea at the time to write a protocol that would dedicate 100% of the senders bandwidth to transmitting data while still adding error correction. Here's how it would work: 1. Sender streams data continuously; but calculates a CRC every X bytes (x=1024 initially), and stores to RAM. 2. Receiver receives data continuously; calculates a CRC every 1024 bytes and then sends back to the receiver over the modem back channel***. 3. Sender looks at CRCs received and if there's a match, continues sending. If there is a bad CRC, the Sender would either end the transfer (like Ymodem-G) or initiate some kind of "resume from previous bytes" control sequence TBD. 4. To help the file transfer end with minimum wasted overhead, I'd probably start the protocol with a simple string indicating how many bytes are in the transfer so the receiver knows when to stop recording. I know there's more to it than this -- the control sequence would still cost something unless I went the Ymodem-G route. The receiver would have to be fast enough to write to disk, calculate CRCs, and send CRCs without running out of modem buffer to prevent delays.. Anyway, in my mind this is 100% or as near to 100% efficient for a one-way file transfer as you can get.. Did anyone ever write a protocol like this? Am I a fool? :) Thanks! John ....... If you like reading: * Zmodem of course could resume and recover where Ymodem-G couldn't, but was less efficient due to certain control byte characters needing to be double sent when they appeared in the stream. ** Ymodem-G though rarely failed on "modern" error correcting modems.. *** USRobotics initial 14.4kbps implementation only had a 450 baud back channel which was limiting, but the industry standard (V.32bis?) was capable of 14.4kbps symmetrically.

Windows 1.04 SDK running in Bochs

All – Through the help of list members Walter Hawkes and Jason Perkins, we were able to move a complete Windows 1.04 development binder set from Ron Herold (also another list member) to NY after VCFE. I have scanned all of the books and manuals (SDK, MSC4, MSC5 and various other manuals) as well as recovered all 39 diskettes (everyone working; no errors). I created a Bochs environment running Windows 1.04 and the SDK, along with MASM 4. Getting the mouse to work was a bear, but it now works. The only software I can’t locate is a version of MS Pascal that’s from the same era. I haven’t tried to build any software with it yet, but if someone wants to give it a try, I can make the Bochs configuration available. At some point I’d like to put together a Web page for it.

The 1st core backplane ise connected to the 2nd by a M920, and the last core backplane is connected to the general purpose backplane with another M920. Do I need grant cards in *all* empty core slots, or can I just put them in the slots that don't already have a M920? Is a core backplane only for core card sets? Can I put any old card in there? Once I get a stable system and it appears the 1st/CPU backplane is talking to the back (4th) backplane (serial card, etc) then I can start testing core in a systematic way, using the serial port. thanks in advance for any suggestions. b -- @ BillDeg: Web: vintagecomputer.net Twitter: @billdeg <https://twitter.com/billdeg> Youtube: @billdeg <https://www.youtube.com/user/billdeg> Unauthorized Bio <http://www.vintagecomputer.net/readme.cfm>

TDL / Apple story
by Evan Koblentz 20 May '16

20 May '16

Herb and I attended Roger Amidon's funeral this morning. We heard an interesting story from a TDL engineer at the luncheon afterward. Herb said Roger had previously told this story; it was new to me. As the story goes, TDL's monitor program was called Apple, so they gave Jobs/Woz permission (at the PC'76 conference in Atlantic City) to call their company Apple as long as they didn't make any Z-80 products. TDL then renamed its monitor "Zapple". I sent Woz a message to ask if he remembers this. Waiting to hear back. Bonus story #1: "Valdocs" meant "Valuable Documents" and was selected because one of the top engineers (not Roger) was a Scientologist and they used that term a lot. Bonus story #2: Rising Star (mostly TDL guys) got the Valdocs interface influence from Claude Kagan's famous "Home Reckoner" paper; they hadn't even heard of Xerox PARC.

> probably the first machine to put a Z-80 in an S-100 system The TDL S-100 ZPU board, was by Roger's account the first available Z80 Altair-compatible (S-100) board product. Roger was proud to note it was released July 4th 1976; those of us from that era recall the celebration of that 200th anniversary of the Declaration of Independence. That's one of many "firsts" or early products in microcomputing where Roger had a hand-in. Roger produced or contributed to many early microcomputer products, and worked with many people in the early era (including Claude Kagan), and later. His remarks of the last few years, suggested he was proudest of his work in gaming; that's discussed in the obituary available from nj.com (Trenton Times newspaper). Until recently, he had regular Friday lunch with several engineers and technologists in the Trenton/Princeton area, including me on occasion. He encouraged lively conversation about the impact of technology on the issues and events of the day. His presence and thoughts will be missed; my condolences to his friends and family.

Finally had time to expand my 32K board to 64K: http://www.glitchwrks.com/2016/05/17/64k-ram-for-osi I think I'm going to turn this into a PC board and kit. Obviously the RAM circuit won't take up even half of the board, so I was thinking about using the rest of the space as a buffered prototype area, with control lines for the onboard Data Direction generator and bus buffers brought out. Thoughts? Thanks, Jonathan

It’s a up. This folder contains the original brochure as pdf, the german text and the english text. I will now start to clean up the text files. Thanks all of the help.

Google Translate does adequate translation from many languages including german, if given clean ASCII text. You can likely clean up the result. Of course...google "google translate" for access.

Fred @ InfoAge speaks German and worked for many years for Amdahl. He is probably qualified. Please send the specific link.

OT: please match subject line and content
by Herb Johnson 17 May '16

Recent messages with the subject line "Cromemco Dazzler 40th birthday presents..." discussed litigation around the "XOR" patent. It's an unrelated subject. A note to moderator Evan: please encourage posters to change the subject line to suit their message content. Why? 1) The VCF maillist archive display on the Web, arranges messages by subject. 2) So people have a clue when reading old or new VCF list emails. Note that I changed the subject, rather than respond under "Cromemco...". I eat my own cooking. However, I read the list from the Web archive, so my emails are hand-composed; that gives me the choice of subject. That has other consequences but it keeps my email traffic and archiving down.
