John,
Try Best Electronics: www.best-electronics-ca.com they have a huge chips
selection for Atari's the SC-01 was going to be used in the unreleased Atari
1400XL and the earlier version of the unreleased Atari 1450XLD, Brad may
have a few SC-01's in inventory when he bought out Atari's stock.

No kidding... I'm looking for one, too! Mine is for the card set from
the Gorf arcade machine. I have one complete Gorf machine (except for
the 19" Electrohome monitor - it died whilst on loan at a friend's
house) and one spare card set, minus the SC-01.
I got the card cages (6 cards, RAM, ROM, I/O, etc.) from a local surplus
house that's now in a trendy part of town - when I was a kid, the entire
area was run down and full of scrappers and strip clubs. :-)
The boards worked fine, but they had no home. I rigged up a wiring
harness from a variety of scrap - PC 5150 63W PSU, an Atari 2600
joystick and a DEC VR-240(?) color monitor (sync on green required)...
it took over the whole table, but it was playable.
About 12 years later, I picked up a Gorf box at an arcade auction (it
had Galaga boards in it - two of us split it up - I got the case/monitor,
the other guy got the Galaga boards). It had been painted over and the
controller replaced with a generic one, but the glass and marquee were
intact. Less than a year later, I bought an unconverted, broken Gorf
from an arcade operator - no glass (shattered), but
unpainted and with
the original controller.
Three different sources, but I did manage to restore a complete Gorf
upright.
If anyone out there has another one SC-01 for sale (I'll wait my turn),
please let me know.
Thanks,
-ethan

There's an Amiga 3000 on eBay that purports to have a
Zorro-II GPIB interface. This is the first time I've heard of one of
these. Does anyone have one? What was it used for? Here's the
auction:
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=2048082800
If you enlarge the photograph showing the board, you can
barely make out some of the lettering on it.
Thanks and take care
Jeff

As I recalled, and as a quick Google confirmed, ASDG made
one for a while:
http://www.google.com/search?hl=en&ie=ISO-8859-1&q=amiga+gpib
As for what it was used for - who knows. I don't remember
a particular application.

Typically (in the instrument world) have a data collection/logger

commonly, especially 10+ years ago, you rolled your own.
I don't think anyone ever shipped a GPIB interface that did not
come with programming support for BASIC or whatever was the
predominant end-user language on the system. Not all users of
GPIB interfaces and instruments also purchased out-of-the-box
applications.
Given the modern Windoze era we are in, I'm certain that there _are_
ready-to-use data logger/analyzer software packages available from
the vendors of said GPIB interfaces, but I personally have had no
experience with them, only home-grown apps.

Am i the only person who associates GPIB more with programmable
instrumentation than with the PET (or with HP computers that happen to
use it for their disk drives). At one time just about every digital
instrument had GPIB availabe as an option (if not as standard).
I now associate it more with instrumentation only because I work for a large
research university ;) I used to associate it just with HP computers because
it was originally HPIB, designed to work with HP machines and their own
test/scientific equipment; they later opened the spec and it became GPIB, as I

I don't think it was long after HPIB was introduced that the first
corresponding IEEE standard was issued. I think Tek adopted it
pretty soon. Things were very awkward before HPIB, with GPIO
interfaces, BCD interfaces, instrument-to-parallel printer interfaces
hacked into GPIO interfaces at the controller side... ugly, ugly.
Let's see: It was announced in the October '72 issue of the
HP journal, and immediately submitted to IEC. It was approved by IEC
as a standard at the end of '75, I believe, after some revisions
and signal name changes; I think IEEE 488 is from 1978,
and 488.1 was issued in 1987. But by the end of the 70's
it was definitely a multi-vendor standard for instrumentation.

I didn't mean to suggest that you didn't know. I was thinking
of the many folks here who have never run across it.

I don't think they did. I remember when the card came out. I
have no memory of any application software coming with it. There
might or might not have been a driver; I don't recall. You might
have had to code to the card, at least at first. ISTR it was
provided more as a curiosity, since the platform physically
supported it, than as filling customer needs, thus the lack of
software support.

I haven't seen _this_ one, but ISTR that ADSG had a stackable I/O
board with GPIB as one of the option modules.
Does anyone have one?
Having never _heard_ of it (and being a big GPIB fan from PET days and
a big Amiga fan from more recent days), I would be surprised if they
sold more than a handful. If you have an old AC Guide, you might look
them up to see if they were ever reviewed in the product guide.
What was it used for?
Talking to lab instruments - volt meters, frequency counters, pH meters,
etc.
If they had a decent driver or an API for C (or possibly BASIC ;-),
one could write code to talk to whatever you wanted, HP and Commodore
equipment, most commonly. I always wanted to be able to hook a 4040
drive or the like up to a modern computer (yes, I know there are ways
to do that now); this would have helped accomplish that 5-10 years ago.
