question: was the s100 board the first version of the Hayes micromodem with the at command set or was the standalone first? I also remember they made one for the apple too... came across the s100 and a standalone version and need to label up for one of the displays.... I should know the answer to this but alas the cob webs grow deep in my brain!

Teletype 33 engineering drawings?

by waltje＠pdp11.nl

Hiya, While going through (some more) Old Stuff, I found the drawings for the ASR33. They look quite delicate, so probably should be scanned asap. Is anyone else in for a copy of these?

museum needs a documation reader that interfaces to a pc

by esharpe＠uswest.net

need a documation reader or other that will interface to a pc so that we can archive card data... need something that is ready to go as with all the projects we have here on the table currently we would not have the time to enjoy doing a conversion ourselves... please advise Thanks!

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 ]

RCA Appnotes

by Robert_Feldman＠jdedwards.com

As an aside, a version of the 1802 was the main processor on the Galileo space probe, which recently ended its mission by being crashed into Jupiter. (There's a nice, general article about Galileo in the September 8 issue of "The New Yorker" magazine, starting on p. 38.) -----Original Message----- From: Brian Herbert [mailto:bkherbert@adelphia.net] Sent: Thursday, September 25, 2003 8:03 PM To: cctech(a)classiccmp.org Subject: RCA Appnotes 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

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

Persci 299

by cmellink＠xs4all.nl

Hallo Peter, Yes, I have the wanted service manual of the Persci 299 drive somewhere in a carton box. Let me know if you still needed! I used to repair these drives, and have some spareparts left like heads, bulbs for the sector indicator (plastic black box) and some very hard to find driverchips for the voice-coil wich I found in Bangkok. Best regards, Kees Th Netherlands

Quick Basic ( a bit of detail)

by r.mueller＠fz-juelich.de

If you should ask me to send a copy of Quick Basic, please be sure you can receive it. I once sent it to a fellow behind a firewall and the firewall bounced it. The set contains executable files and they could be dangerous (Indeed, you have to trust ME not to insert a virus, but then again, I don't know how! Don't even want to know how.) Bob

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.
