Yah, it was a 325572 and I have 3 of them kicking around. :-)
The ones that I have that are still good (or were the last time I tried them)
are in storage and currently inaccessible to me.
I do have roms, though, on hand here, for both the c64 and 1541, in
several versions.

What LSI
controller? They have a 6502 on there, a couple of ROMs, and
in some cases a gate array chip that just replaces a bunch of LSTTL and
makes it cheaper for them to manufacture
Oh, it was a gate array? I knew it was some custom chip, I just wasn't sure
if it was a custom LSI or a gate array... It certainly has a Commodore
house part number on it IIRC. (and I have
some of those on hand if anybody needs some :-). Aside from
that there's an NE592 preamp chip, and the rest is a couple of 6522 chips
and a handful of LSTTL for the interface and clock generation and whatnot.
You could probably stuff that lot into an FPGA, but I don't know if
anyone's done a cycle-accurate 6522 HDL model yet. There's certainly free
6502 models out there though - Free6502 (which used to be on Free-IP) and
the like.
I really should try and do that once I've got some spare cash lying around.
Could really do with getting a C-64 and a known-good 1541 first though...
