More likely SCSI (single 50pin cable) or EDSI (two
cables like MFM).
MFM drives topped out at 160mb or so, EDSI went to at least 400mb maybe
higher.
ESDI, and I know they can handle higher capacity disks (though I can't
speak to the actual limit) as I have several ESDI disks which are
770mb unformatted (about 668mb formatted). A couple of them are the
Hitachi DK515-78. I also have some Maxtor drives, but I don't remember
their designation.

New subject: Today's Archeological Dig
I stumbled upon the elusive DIGIAG 2010! OK, before you wet your pants,
this is just an old logic trainer, but a cool one with requistite toggle
switches and blinkenlights.
But something truely elusive that I've been trying to track down ever
since I was aware of their existence: GO prototypes! Anybody who has read
Kaplan's book about the demise of GO (Startup: A Silicon Valley Adventure)
remembers the final days when they liquated GO's assets at auction. I
bumped into a guy who bought-out the storage area of some guy that bought
a bunch of the stuff from the auction! I hope to pick up more doodads and
tech specs from him tomorrow.
A Tandy PDD2 floppy drive.
A couple of GRiDs: a 1910 and a GRiDLite.
A couple of books: Don Lancaster's TTL Cookbook, and Trouble Shooting and
Repairing your Commodore 64.
A few Popular Electronics and Radio Electronics, including the issues with
the SOL (PE July 76), TV Typewriter II (RE Feb/Mar/Apr 75), COSMAC ELF (PE
Aug 76), and an RE May 81 issue that reviews the MMD-1, SYM-1, ELF II,
COSMAC VIP, and Heath ET-3400!
