A batch of these was just offered on ebay; I purchased 5 of the DS8641N
and 10 of the DS8640N. He still had 10 more of the DS8640N in his
auction. I want to make some sort of emulated drive interface for my
11/03 so that I don't have to put wear and tear on the RL01 drives in
order to play with it :-). Plus it would give me access to much
larger storage capacity by using some sort of emulator or whatnot.

It looks like it to me - from the schematic, he's using old National
chips (8838, etc)... not a bad trick for a one-off, but not so easy to
manage for, say, an new community design. Personally, I collect all
of the NS 8xxx chips I come across (a handful per year), more to
repair old boards than anything else, but someday, if an interesting
design crossed my path, I'd have parts to build one.
