Ebay help, please.
How comes that things like that CANNOT BE FOUND thru EBAY Search(es ) ???
i.e. Take a part of the item description : "Wang VS7150"
Do an Ebay search ..... and ( at least for me, from France ) You won't get any hit !!!
Why ????
Is that an Ebay Bug ?? Is it known ??
( Of course, it is NOT the first time that I come across that kind of Ebay bug, that is why I am calling for help ;-) )
Will the gent who emailed me that he wanted these please email me again with
your address, etc.
Very sorry, but your previous email got lost in the shuffle.

I have an old DG Aviion server here, has qty 4 Pentium Pro 200 chips. No
idea what the model number is, sorry. Local pickup only. Plenty of 4.3GB
SCSI hard drives to go in it. Probably still have some old memory to go in
it.

How are you fixed for doc & spares?
I have a TC59 on one of my pdp-15s - I have doc and I think I have
some spare boards...

Could be interesting .... As I am not too far ....
BUT ** IF ** system has Disk Pack Units ( Drives ). And, from the pics, I do not see any ???
Someone does ??

unless I'm mistaken you're in Australia. and that being the case don't feel too bad this was hardly a museum quality piece. It's obvious rareness made me think someone could have used parts. But I'll keep you in mind if I should come across another.
Warren Stearns and I have been working on the PDP-9 at the RICM.
Yesterday we got the core memory working and started debugging the
processor. Quite a milestone for a 44 year old system.
All of the operate instructions seem to work. The JMP and ISZ
instructions are flakey, even when single stepping. This could be a
microcode problem, or a problem with the data multiplexers.
It is an interesting machine because it is microcoded with read-only
core memory. I am not sure why they used core for the microcode. Maybe
just a board with a bunch of diodes would have done the same thing and
would have been a lot simpler?
I am finding the schematics a challenge because they were created
before ANSI or IEC standard logic symbols were invented. Eventually I
will understand the symbology.
Some of the design is a little strange because you can abuse DTL logic
in ways that TTL will not tolerate. Lots of delay lines where you can
adjust the delay by changing wire-wrap on the backplane. Lots of pulse
amplifiers to improve fan-out and reshape signals.
You can read about our debugging progress here.

We need to fix the paper tape reader so we can load some of the diags.
We are a long way from connecting the TC-59 and the TU20.
I suspect that getting the TU20 working will be a challenge.

Perhaps it's just a solder crack. If you dismantle it enough to get at the pcb's bottom you could touch each blob with a soldering gun. I have fixed at least 1 unit that way (it worked after I did anyway).
Would anyone have a distribution for MRRT-11? I'd really like to find a
copy if anyone has it or can give me a pointer.
[What the heck is MRRT-11? "Memory Resident RT-11" - it's a hacked up
version of RT-11 that runs diskless. It was an official DEC product sold in
the late 70s.]
Thanks,

I disagree. By comparison it lacks features compared to the Tandy. As does the Sanyo. They share enough to make the comparison. I wouldn't for instance make the same comparisons between the 1000 and 2000. They're just too different, but in many respects the model 2000 is a more powerful machine.
