I recently picked up some memory boards for which I have no manuals.
If anyone has documentation for these and will loan the hard copy to me, I
will scan the manuals to PDF files and make them available on Howard's site,
and return the originals. Of course if anyone has a scanned version in any
format, that works also.
There are two boards:
-"Thinker Toys" (Morrow) 32K Superram S-100 memory board, (c)1978. Board
has 64 type 4044 or 5257 4kx1 static memory chips
-"Thinker Toys" (Morrow) 16K Superam S-100 memory board, (c) 1978. Board
has 32 type 2114 memory chips (are these and the 4044/5257 all
interchangeable?). Board has six 8-position dip switches on it, plus an 8
position jumper. Even allowing for both bank switching and 24-bit
addressing, it seems like a lot.
Thanks,
