It's been a while since I have picked-up any _digital_
computers, but I just could not resist this. I found
someone selling a Ohio Scientific Model 600 on eBay,
and when I went to check was it sold for, I discovered
that no one wanted to bid the $20 minimum bid.

So I asked for a picture of the computer to make sure it
wasn't just a baggie full of spare parts.

I paid for it and it arrived today. There seems to
be only one empty dip socket that looks like it should
not be empty. It looks like the key caps for the numbers
were removed on purpose. Without taking it apart, I can
see one ROM labeled "BASIC 3", and two EPROMS labeled
"BASIC 4 modified 12/21/81" and "SYN 600 MOD".
I found one web site that also calls this a SuperBoard II.
The main board says:
"Ohio Scientific Model 600 CPU _at_1978 Rev B"
The large daughter board says:
"_at_1980 AARDVARK". And it contains a MC6821 PIA.
The small daughter board contains three 2716s labeled
"REV 94 I", "REV 94 II", and "REV 94 III".
All in all it looks to be in very good condition,
but powering this up is going to have to wait. My
wife wants my current projects off the dinner table
and the analog flight simulator and the paper tape
punches out of the dining room.
