Hi all --
I just picked up an interesting device, it appears to be a drive
emulator that adapts DEC SDI to either ESDI or MFM drives (I would guess
ESDI, but no real way to be sure.) It's manufactured by "Micro
Technology" and is labeled as an "MDI 240" on the front. (On the rear
as "SPEC.MDI-240", P/N "970176-000".)
Mine has no drives in it, just a power supply and two logic boards
labeled "MSD13B" that connect to the drives. I can't find much
information about this unit at all, and just a bit about Micro
Technology (apparently they were sued by DEC for building this device :)).
I'd like to be able to use this thing (possibly with my VAX 11/750).
Anyone have any information hiding somewhere about it?
Thanks,
Josh

I have a box at home with _a_ SDI->ESDI board and two 600MB ESDI
drives. I will see about cracking it open to see what's inside.
I would have no docs, though... mine came to me in working order and I
just plugged it in. I'm using it with a KDB50 and my VAX8300. No
funny business. It just works.

Thanks. Even lacking docs, if you have the same (or similar) SDI->ESDI
board that's in mine it would be useful to know. It'd probably also be
interesting to know what model drives you have in there.

Sure thing. I don't know model numbers off the top of my head, but
the drives are whatever 5.25" full-height ESDI drives would have been
common in that era, and I can take a photo of any jumpers.
