I'm not familiar with this particular machine, but I used to have a similar
286 based machine. A noname tawianese brand, model HL3200 or some such.
Designed to look like the Toshiba 3100, but with EGA and an MFM HDD.
The main problem with replacing the power supply with one from a generic PC
is that the original supply probably had a high voltage output to drive the
plasma display. In my 286 machine it was 205V. If you use a power supply
that doesn't have the 205V line you'll be able use an external monitor, but
not the plasma display. Which would kind of defeat the purpose of getting
it running these days.
Your best bet would be find a power supply from another machine. One from
a 286 based T3200 might do, as may one another machine with a plasma
display if you can work out what goes where. It probably won't fit in
space where the original power supply was. Either way I'd retrieve the
original power supply from the garbage to work out what goes where.
I had mine many years ago. I found it in a dumpster with a cracked screen
and no drives. This was when back when a 286 with EGA was something
special, at least to a 13 year old with no money. I got it running on an
external monitor and dumped the broken plasma display. It lived out the
rest its days in a plastic case that once held an apple 2 clone, a naked
5.25" FDD and a 30MB MFM HDD at it's side. I completed Leisure Suit Larry
1, Duke Nukem 1, Catacombs 3D and others on this beast before upgrading to
a Wang 386-16 (a full size case with room for 2 70MB MFM HDDs with noisy
bearings!) and a flaky VGA monitor with serious screen burn. A good used
VGA monitor cost around AU$200 at the time so I has to settle for one
removed from an old memorex terminal, but I could finally play Wolf 3D.
Bzzzt. Wrong answer.
I worked at Sun in the OS group and the first release that had my code
in it was Solaris 2.4. I also have bugfixes in 2.3.
Solaris 1.x is the BSD-based stuff; Solaris 2.x is the SVR4-based stuff.
SunOS is the OS proper and Solaris is the entire environment. SunOS
4.x went with Solaris 1.x and SunOS 5.x went with Solaris 2.x.

The way I remember this, the first release that bore the "Solaris"
name when released was 2.5 . Before it was called SunOS, of which
the last release was 4.1.4 if I remember correctly. After Solaris 2.5,
the previous SunOS 4.x releases were renamed "Solaris 2.4". I think
that the list of releases that I played with at one point or another is
as
follows:
SunOS 4.1.1 Rev B
SunOS 4.1.4, aka Solaris 2.4 (or was it 4.1.3?)
Solaris 2.5
Solaris 2.6
Solaris 2.7
Solaris 8

I don't think it's even exiting power save. When I turn it on the power light comes on and there's a click from inside the monitor. After a few seconds the yellow power save light comes on and then I hear another click from inside the monitor. When I turn the Indigo on, it powers up and plays it's tune so I know that it's started but nothing changes on the monitor.
I disconnected the video cable at the monitor and looked for sync on pin 3 and found that there was no sync* unless I started the Indigo with no monitor connected. (The sync was 63.something kHz). If I then connected the video cable to the monitor both the yellow power save and green power lights started blinking.
*I don't think the lack of sync on pin 3 indicates a problem. This monitor is suppossed to Sync-on-Green. In fact, the lack of sync on 3 when I boot the computer with the monitor connected may well indicate that the computer recognizes that this monitor doesn't use a separate sync signal.
The computer is definitely working. After trying these monitors I plugged the video cable into my usual monitor and everything worked exactly as it's supposed to.
I was wondering, if I use a logic pulser and pulse the green input on the monitor will it generate random garbage on the screen? Any thoughts on that?

Sorry it took so long to get back to you. I'm located 25 mi. south of
Chicago. This computer was bought around 1985 for around 38 thousand dollars
including software and support. It was used to evaluate Cummins diesel
engines by running through various sequences measuring the time and
pressures it monitored and compared these values with the database loaded.
the unit ran from two floppy's, I have to add the software was very buggy
and the support program from Cummins engine company did not help much. I
have included pictures you can access via
http://reo-solutions.com/gallery/ti-990a13 . If interested please contact
me.

I think I may have already posted this request but I am still searching
for this.
I need a data sheet for the AT&T T7525 codec. The document should be
dated between 1991-1994, but at this point I'll take any data sheet for
that chip.
If anyone has this, please e-mail me directly at <sellam(a)vintage.org>.
I need it by the end of the week.
There i$ a reward for thi$!!

I didn't realise they were so different inside. I knew the Ace didn't use
the ULA but I thought the basic architecture was similar to the ZX80/ZX81
(apart from the screen memory, which I knew about). There was certainly a
rumour at the time that that was the case, but I dare say that was as much
due to the similar size and shape of case as anything else :-) Perhaps
"inspired by" is better than "based on".
I have the manuals for ZX80, ZX81, and the Jupiter ACE, and the service
manual for the ZX81, but the only one of those machines I possess is the
common-or-garden ZX81. Twice I've just missed getting a ZX80, and I've
seen a few, but I've only seen seen one ACE.

Hey I just got a Commodore and a 1541 floppy drive
I know
load "$",8
loads a catalog of what's on the disk and
load "name",8
will load something from the floppy
and I assume
save "name",8
will save it
But how do I format the disk and prepare it for use?
Thanks for your help...
Ron.
Where are you??? Wicats are *COOL*!!

Sellam,
I have the set of "inside the TRS-80 xxxx" books. I'm sure that the TRSDOS
1.3 is included.
I'll have a look.
I can scan anything that you need.
