For the KIM-1, the only definitive source is the ROM, and that only has patterns for hexadecimal: * HEX-TO-LED SEGMENT CONVERSION TABLE * SAME AS $1FE7 IN THE KIM ROM.

Another source is issue 1 of the KIM-6502 User Notes, which has a slightly different alphabet: DB $BD,$F6,$86,$9E ;G H I J DB $B8,$BF,$F3,$ED ;L O P S DB $BE,$EE,$FC,$D8 ;U Y b c DB $DE,$F1,$EF,$F4 ;d f g h DB $84,$9E,$86,$D4 ;i j l n DB $DC,$F3,$D0,$F8 ;o p r t DB $9C,$EE,$C0 ;u y minus DB $F0,$B7,$D4,$E7 ;k m n q DB $BE,$EA,$9C,$94 ;q v w x DB $C9,$D3,$80 ;z ? space You can find the KIM-6502 User Notes at www.6502.org in the publications section. -- Paul R.

If no-one else wants them, I'll take the Atari Jaguar & Lynx, but I live in the UK so they'll need posting (I'll happily pay for P&P costs). Regards, Andrew B aliensrcooluk at yahoo.co.uk

Strange modem...

by aliensrcooluk＠yahoo.co.uk

Hi all, Just had a box come today. Inside are around 32 discs from CU Amiga and Amiga Format. I plan to catalogue them along with my other Amiga CD32 stuff during this week (I have the week off). Also in the box is a 56K (Data/Fax/Voice) modem, manufacturer is unknown. It simply states on the front end... "56K V.90/K56 flex" ... with more data on the bottom of the kit: "FCC No.: H52PT-3020 Data: K56 Flex/ITU-T V.90 & ITU-T V.34 MNP 4/5 & V.42/ V.42 bis Fax: G3 14.4K/14.4K Send/Recieve Voice: Simultaneous Audio/Voice & Data; Full-duplex speakerphone mode Power: AC 9V/1A Made in Taiwan" On the front it has two sockets for a mic. and a speaker to be plugged in along with 9 lights for: RD TD CD OH AA HS DTR MR PW I think I know what most of them mean. On the back it has an on/off switch, a power socket, a parallel port style socket (I have necessary cable), line socket and phone socket. I assume the line socket plugs into the phone connection socket, but what's the phone connection for? To plug the phone/fax line in?? I also have Active: Netconnect CD's V2 & V3, so having software to go online shouldn't be a hassle - I just want to upload and download stuff from Aminet (site for storing various Amiga files, utilities, games, patches and more) Regards, Andrew B aliensrcooluk at yahoo.co.uk

QIC 80 drive needed

by aek＠bitsavers.org

> he happened to drop that he had a A/UX tape that he could not read as his tape > drive had "gone goo" It turns out to be A/UX 1.1 (!) I really hope he didn't discover this by attempting to read the tape. If so, he now has goo on the tape, and it will be extremely difficult to recover. FWIW, I have an image of A/UX 1.0, made in the days when the only way to get a copy was to go over to Bubb Road with a disc and have the original A/UX group clone it for you.

by ajwills＠paradise.net.nz

Did anyone happen to download "Zebra_Design.pdf" "An Outline of the Functional Design of the Stantec Zebra Computer" which was made available on this list in 2002 by Hans Pufal ? Does anyone have other Zebra documentation? Tony.

Sipke de Wal, xgistor.ath.cx, and SC/MP emulators

by ajwills＠paradise.net.nz

Hi everyone, I have been looking for Sipke de Wal's SC/MP emulator and of course found the note about his death in 2004 (http://www.classiccmp.org/pipermail/cctalk/2004-May/041480.html). Looking at the fragments of his website still available in the internet archive and on Google, I see he had a lot of interesting pages and downloads many relating to old computers and processors. There are still many sites on the internet that link to his website that hasn't existed for 2 years now. It seems a pity that all that work has now disappeared when the storage requirements and bandwidth, to maintain such a site, are quite modest. I would be happy to host a copy of his site if it could be reconstructed. I've reconstructed his SC/MP webpage (but still don't have a copy of his emulator). So a number of questions: - Did anyone here download anything from his site that they've still got (webpages or files) ? - Does anyone have contact with his familiy ? - Did anyone know Sipke well enough to know whether he would approve of the resurection of his website? Any help appreciated. Tony.

WANG micro? found

by david_comley＠yahoo.com

----- Original Message ---- From: Jay West <jwest at classiccmp.org> To: General Discussion: On-Topic and Off-Topic Posts <cctalk at classiccmp.org> Sent: Saturday, September 30, 2006 3:40:31 PM Subject: Re: WANG micro? found I took more pictures of the unit after removing the chassis. They can be found at: http://www.ezwind.net/jwest/wang The cpu main board is definitely the large L-shaped one that Roy Tellason mentioned. Just eyeballing it, but what kind of backplane connectors are those? They look larger than ISA connectors and appear to be 86 pin. It seems to be quite clean inside and out. Not that I've had much time for classic computers lately, but this one may be interesting for a while :) Jay
