Long shot indeed! DECtape drives are one of the rarest DEC peripheral, and
un-surprisingly, one of the most valuable. (A TU56 sold on eBait for $7K back
Would a TU55 do, or does it have to be a TU56? (The interface is basically
compatible, I think, but I have yet to dig into the details, so I can't
say for certain. But I think I recall seeing systems with one or the other,
and AFAIK the controllers aren't drive-type specific - the cabling might
I ran across this modem (circa 1982) and saved it, but I have no idea on
how to control it. Bitsavers doesn't seem to have a manual for it.
It's a big, blue plastic box and it looks wonderful. There is an array of
8 lights and 6 buttons; the HS button enables 1200 bps operation, otherwise
it is 300 bps. It echoes characters and responds correctly to
DataTerminalReady not being asserted, so I think that if I can find the
command set it might be functional.
It's a little more primitive than my original Hayes 1200 that I first got
in 1984. (I'm not expecting a standard command set.) A picture of it can
be found here:
A collection just came to me. These are the original disks, with whatever labels are on them.

I also was searching about a clear SMD specification years ago, I found
something in disk documentation from CDC, but doubts remain, because some
disks call the interface SMD, some other CMD, never understood the
well maybe my memory has blank spots.
I have two CDC Lark Disk modules I would like to revive, they are in good
shape, but only one has a cartridge included, and they are not identical.
Not sure if the other one could be employed without cartridge.
I never found a manual with exact model correspondence, I found years ago a
manual for very similar drives.
IIRC there was a sort of adapter board between SMD and (xxx blank spot)
interface. There was a description of the interface, it was really similar
to SMD, but wasn't SMD...
Maybe I should check again the Lark model number.
I?ve been trying to find *detailed* specifications (mainly detailed signal timings) for the SMD disk interface but all I?ve found so far are the interface specifications for individual disks (CDC, Fujitsu, etc). I?ve looked in the usual places (bitsavers mostly) and haven?t found the spec itself. If anyone has any pointers, I?d appreciate it.
