OK, it just booted. The only difference was I turned the VT420 off, and
the BA123 had been sitting powered off while I wrote my panic message. I
decided to give it one more try before crashing for the night in dispare.
I'm totally confused. Either it needed to sit for a few minutes, or the
terminal needed power cycled. Or maybe it was waiting for me to panic and
act foolish :^)
Argh! Ideas?

OK, I had the PDP-11/23+ board in place, and the system loaded up. I was
testing out the memory boards I've got by swapping them in. It didn't seem
to like a pair of clearpoint memory boards I've got, and then I put in the
M8637-EC board, and NOTHING works. It won't even come up with the info on
the /23+ ROM. I've a very bad feeling about having put ECC RAM in it.
I went so far as to pull out all the boards, nothing. I swapped the /23+
with a /73 and still nothing! What on earth did I do? The diagnostic LEDs
on the /23+ are D1, D2, and D4 unfortunatly the manual I've got on the
board doesn't seem to explain what the LEDs mean.
It's as if I managed to fry the backplane, but that really doesn't make sense.

30 days and it's going to the metal scrapyard, would rather see her have a
good home.
It would have to be PC-DOS 2.10. Version 2.11 was MS-DOS i think. I have a
copy of 2.10 on the shelf with the book. I don't know anything about PC Jrs
though, with the exception of a thrift store here in Portland, OR that has a
monitor for one.
If you are interested in the SW contact me directly. I was actually looking
for DOS 1.XX to see if I might have it. I don't but I ran across the book set
marked 1.01 for the 3270 PC. I got excited but what was inside was PD-DOS 3.0.
Oh well, such is life. I have lots of versions of PC-DOS 3.0 & 3.1, and a
couple of MS-DOS 2.11 for other computers that I am interested in unloading.
Any interest out there.

Nice going ace!
Here's an idea for 3.0...get somebody close by with a working, large mini
configuration or small mainframe and have them spend all day assemblying and
wiring and booting it and demonstrating it the next day. A good full install
should day all at least.

Hi Joe;
Nice find.
Almost any NEC multisync momitor will work. There is a adapter that goes from
9 pin to apple for the older multisync monitors and another 15 pin to Apple
for later monitors. I can get them here in Portland, Oregon at Oregon
Electronics. You should be able to find a cable house in your neighborhood
that has the adapter or a cable that would work. Other monitors like the Sony
should work also.

The Xerox 16/8 is a desktop CPM Computer of the mid 1980s vintage. It has both
8 and 16 bit processors in the cabinet. I believe the original computer was
based on the UK Big Board design. The 16 bit processor is on a propriatory add
on card. It runs CPM-80 & CPM-86. If I remember right it will run an early
version of MS-DOS.
It has been years since I have run mine. My 2nd computer was a Xerox 820, an
earlier model. I was delighted when I got a 16/8.
It uses external drives which you may not have gotten. The disks availiable
were dual 8" floppys, dual 5" floppys or a 8" Floppy and 8" HD. You could use
only one set at a time. Brian of Emerald Microware (business no longer in
existance) in Beaverton, Oregon made a data sharer that would alow you to hook
up both 5 & 8" drives at the same time. He supported this family of computers
for many years. It was a nice machine.
There are two styles of keyboards, the original which is bulky and a low
profile which uses a different ROM. The basic computer consists of three
pieces, the Monitor/CPU, a keyboard and a drive cabinet.
I have docs, drives, cpus and parts if you want to communicate with me
directly.

it's just like a standard pc in that if you have a boot floppy, preferably dos
2.1, it should load. or, if a cart is in one of the two front slots, it should
load off of that. the disk drive in it is the same as the slim height floppy
drives the portable pc used.

If anyone needs a couple of memory boards for their MicroVAX, here's a
fellow offering a couple of 1 meggers dirt cheap.
