Good evening gentlemen, I have to ressemble the HP 97cardreader - and have

Thanks a lot!

It possibly is.

Thanks -- that's most helpful.

How many sheets are in the set? I wonder if you could copy it. I know you
don't have regular access to a copier, and not to an A3 copier, but the
schematic in sections would be useful. But first, I'll see how far I get
now I know the pinouts.

One of the best games of all time. I never really got into the C64, I was too
busy
building disk drive controller boards for the Atari or trying to get fig
forth to run.
Sad but true :-(
The C64 was a really neat machine but had a few hardware reliability problems.
The PAL and the graphics chip were prone to early failure. At one time I used
to fix two or three machines a week for a friend who owned a TV repair shop.
He bought scrap machines from high street dealers and I would end up having
to fix them.
However, some of the games for these machines were works of genius. I really
admire the people who had to write the software, mostly in assembler, and too
impossible deadlines.
The same could be said for the "speccy". Not exactly reliable but for three
chips, Z80, current injection logic ASIC, sound and some DRAM - WOW !
The cassette interface could be a problem but when faced with the prospect
of having to rebuild DC100 tapes, ( including drilling holes in the tape ),
and
replacing the drive wheel in an HP tape drive - I'd go for the "speccy".

At the place I picked up my 9-track tape drive they had a Nile 150
system with storage unit that they're looking to unload. I don't
know anything about the system (nor did they, other than the guy
telling me about the system said it has MIPS R4x00 CPUs).

Ulp ... Adrian, what part of the US? Any idea what became of the machine
eventually?

Hi again,
I neglected to mention in my last power series post the odd video connectors
on this thing:
1 analog video in/out breakout plug. (The same as the plug for the Galileo
breakout, I believe)
2 "Digital video out" plugs. (They look like 25-pin or so parallel plugs,
female)
7 BNCs. I assume 4 of them are the R, G, B, and S for the monitor. The
others are labeled "Alpha," and are also red, green, and blue. What do I do
with them? :)
Regards,
Chris
