Hi List,
I've started looking at my SDK-85 after having it on the shelf for
years. I know the 8355 mask ROM on it isn't working but I haven't been
able to find a suitable replacement. I wired up a temporary solution
with a 2716 EPROM only to find the ROM image and source code aren't
available out
I believe I can help with this. Although I do not have a spare device, I do
have the binary as Intel hex as I had the same device fail on my SDK-85 and
went through the exercise replacing it. I'll report back off list once I dig
up the file.
Chris

It will depend on price - will they be the same as the PDP-8 panels (since
they are so similar)? If so, can you remind us of the pricing, please? If
not, any estimate?
I assume you'll eventually be doing all of them (/3

For what it's worth a small warning about the HP 9825 series computers.
The power supply doesn't have a crowbar(over voltage protection), so a
transistor failure in the Psu can be catastrophic.

Thanks for the info. Any schematics of the modification?

I sent him a private email with a binary dump of the 8355 from my SDK-85.
It shouldn't be hard to find an Intel 8755 EPROM version of the 8355
ROM version. Then you just need to find someone to program it if you
can't program it yourself. I can program 8755 parts, but postage to
Australia might no

Yes, exactly that one! Based on the rest of your e-mail I'm guessing
it's yours, right? Any chance you could get a higher res scan of it?

I can see that one day's notice did not do much good. I am sorry, but
Atlanta is over 1500 miles from home for me, and I usually do not get much
notice. Next time I will try to give at least a week notice.
There can be absolutely no viewing on the weekends. That is out of the
question for him.
There are a couple of 56K-xxx AT&T keyboards there, but I counted, and there
are only 6 wires in the female connector. There is not a fixed cable.

No, I am not interested in selling. Trades only please, sorry. :(
No, I am not interested in 90s workstation hardware- really looking for

Thanks!

I wonder if the crowbars might have been a later revision of of the
power supply. After the accident with my 9835A I had to completely
rebuild the +12V regulator both the 723 and the pass transistor as well
as a few passive components. I did not see any evidence of crowbars,
and the power su
Marc,
Building a crowbar is easy, just take a Zener a little higher than the psu
voltage eg 5.2V for 5V rail put a resistor of 1k in series take a Thyristor
big enough to take about 150% of the schort current and connect it to the
zener through a small resistor. I suppose you can do the math ;)
