Hi everyone,
Being personally quite interested in DEC's laboratory systems, I
stumbled a few days ago upon some scant details on DEC's nuclear medical
imaging system, the Gamma-11. Apparently this PDP-11 was designed to be
connected to a Gamma Camera, and had a VT11 or VSV11 display system
connected to it. As well, along with it came a modified version of
RT-11.
I was wondering if anyone on the list had one of these machines and knew
what parts made the hardware a Gamma-11, as well if anyone had manuals
online that they might share, as well as potentially the software for
the unit. There's not really much that I can see on Bitsavers, but I
might not have looked hard enough; I found the VSV11 and VT11 option
manuals, but that seemed to be about it.
Cheers,
Phil
Memory for Indigo 2 (IP22) needs to be FPM with ECC. But I couldn't
find anywhere if these SIMMs may be "registered", aka "buffered".
I see quite a few cheap FPM ECC SIMMs for sale, but most of them have
some strange additional chips on them, I guess that means there are
of the buffered kind. Will these modules work in I2?

That might have been me, but he's also on this list; Golan, are you listening?

Disk detection on the Persci 270 series drives (and I think on the 299
series drives as well) is simply a microswitch triggered by the leading edge
of the diskette.
There are NO electronics in the insert detection / clamp / eject mechanism.
It is a trivial circuit consisting ONLY of a DC electric motor (24 volts, I
think) and 4 microswitches (two of these are operated by cams on the motor
shaft, one is the front panel eject switch and one is triggered by the
diskette itself when it's pushed in). All you need to troubleshoot it is a
multimeter. It has no connection to the actual "electronics" of the drive.
It's just straight DC electricity. Schematics are available on the Harte
site and in other places if you don't have the manuals.
The only thing different about the CS3 implementation is that they removed
the front bezel of the drives, and then replaced the eject switches that had
been part of the drive's own front bezel (now removed) with a switch on the
CS3 chassis. I don't remember if they connected this through the switch
wires left over from the (removed) Persci front bezel or if they did eject
through the 50-pin data interface connector (Persci did allow an eject
function through the 50-pin data cable).
Folks,
I'm looking for VAX Ultrix 3.0C. TUHS doesn't seem to have it, nor
does Bitsavers, but I'm hopeful someone on this list might have tape
images they'd be willing to share. It used to be an extremely common
VAX UNIX in the wild, so I'm hoping it still exists somewhere.

Hi,
Over the Amiga's life, several devices were produced that connected to
the 23-pin video port, and allowed more colours to be shown.
I'm aware of at least five. Were any other video port devices produced?
- HAM-E from Black Belt Systems
- DCTV from Digital Creations (this also plugged into the parallel port
and the hardware included a video digitiser)
- ColorBurst from M.A.S.T.
- Fun Color from Adept Development (saw this on amiga-hardware.com)
- Graffiti from Individual Computers
Technical info on the Graffiti is available from the Individual
Computers web site, but I couldn't find detailed docs on any of the
others.
I would like to get hold of:
- Technical details about how the hardware works for DCTV, Fun Color,
ColorBurst and HAM-E. (I got a little info on the HAM-E from an old
Usenet posting.)
-Details of any chips inside any of the devices. or just high-res
pictures of the circuit boards.
- Any software that came with ColorBurst & Fun Color (DCTV & HAM-E
software is available on the web, but other versions of those would be
good to have too.)
So if you have that or know where I might get it, please let me know.
(The eventual aim is to allow Amiga emulators to support at least some
of these devices.)

I have the manuals scanned, but they aren't on line yet, since it hasn't been
a high-demand item.
Someone here posted about a friend in Canada who has boxes upon boxes of
unopened blank DSDD 5.25" floppies. Who was that? I think I deleted the
relevant emails (or at least grep is failing me).

A: Because it fouls the order in which people normally read text.
Q: Why is top-posting such a bad thing?
A: Top-posting.
Q: What is the most annoying thing in e-mail?
I have a nice, apparently functional external IBM 8" floppy drive, model
9331 011 that I'd like to hook up to a PC FDC. It has a 37-pin D-sub
connector on the back. Searches for pinout info have returned nothing
useful. Information about the 37-pin connector, or the pinouts of the
drive inside the enclosure (a YE-Data YD-180 type 1601, which I've also
not found any reliable info on) would be most appreciated.
Thanks,
Josh
