OSI did not release the source. Once upon a time someone I knew in a large
3-letter
computer company disassembled OS65-D over a month or two of watching
football games on TV. He was the kind of guy who needed to keep his mind
busy while watching football..... He eventually got a set of commented
source that would reassemble and run, and we were able to add a new printer
driver to some jump table.
I have no idea if he is still around, and if the source is either. I'll ask
about.
That disassembled OS65D listing had something to do with a big fight that
ended up with the IBM PC having the BIOS LISTING!! in the TechRef.
But that's another story....

You don't need to, just OR the result with $20.

Hi
I have A PDP8/A with a Cirus logic Processor
board set. This uses the other DEC IO boards but
has it own Processor board set. I seems to work
but I have not figured out the Console ports and
if one can Bypass the ROM boot.
Thanks, Jerry

You made me go to the basement to verify... Let's
see: Toast 3.5.7, Jam 2.5, MacOS 7.6.1 on the IIci,
and MacOS 8.6 on an 8100.

Hi, ALL
I'm working a DEC PDP8 M8316 console board and
need a Signetics N8234N IC. Can't seem to find
them with out spending 100.00 minimum order.
Any pointers would be helpful.
Thanks, Jerry Wright

Mine are shot and I was looking for replacements. I found this site
part DAL-2EJ100 that looks like a acceptable replacement but min buy of
50 at $4 each = $200
http://www.capacitorindustries.com/excessinv.htm
It looks like the existing ones are 2" by 4 1/8", these are 2" by 4.92"
which seems like they will fit ok.
Is anybody else looking for capacitors who would like to split an order?
If so email me and I will buy them and split across all the interested
people.
Know of any other good source?
as an aside to this thread, the Victor 9000/Sirius
micro, an 8088 system purported to operate in minimum
mode, used a disk scheme similar to Macs. More data
was stored on the outer tracks, squeezing 1.2meg I
think onto a DD disk. Theres a site based in the UK
with gobs of software. Good luck hacking up a boot
disk though. Victor was a reputable calculator maker
at one time, but flopped in the PC business. Their 2nd
model, the VPC-II, a real compatible, is less seldom
found. Mine lacks the keyboard :(

you guys should post some pics of your boards and
stuph. In the event of a lack of a place to put them,
use the photo area of the Midatlanticretro yahoo
group. You have my express permission LOL LOL. And Al
lives in the area, and wed love to have you sign on.
To my knowledge there is currently no member with a
specific interest in STs (besides me).

I just rescued a complete IBM RT PC. It includes all the documentation.
AIX 2.x software, extra keyboards, extra cards, extra HDD;s and extra
tape drives. It also has an extra ESDI hard drive labeled Reno 4.3.
Was there a port of 4.x BSD to the ROMP processor? I thought that it was
tried but not completed.
There is also a backup tape labeled AOS?
The whole system looks like its in pretty good condition. And maybe
after consuming mass quantities of turkey tomorrow, I'll see if it boots up.
Cheers
Tom
