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.
DB $BF,$86,$DB,$CF ;0 1 2 3
DB $E6,$ED,$FD,$87 ;4 5 6 7
DB $FF,$EF,$F7,$FC ;8 9 A b
DB $B9,$DE,$F9,$F1 ;C d E F
As Mr. Veit has written, the First Book of KIM has
more letters. Another source is issue 1 of the
KIM-6502 User Notes, which has a slightly different
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

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).

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

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,

hassle - I just want to upload and download
stuff from Aminet (site for storing various
Amiga files, utilities, games, patches and more)

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.
I'm posting this for a friend. Check out the pictures at

Looking for Digital Equipment Corp. PDP-1 through PDP-15 minicomputers!
I'm looking for an 800 bpi readable tape drive,
with either HPIB or SCSI connection.
(Or option 800 for the HP7980/88780 tape drive,

Any leads would be appreciated.
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?
I have been looking for Sipke de Wal's SC/MP emulator and of course found
the note about his death in 2004
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.

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 :)
