I have a keyboard. Possible snag: I live in Prague, Czechia.

Hi Bill
Back with a suplementary query.
Do you have a pin out for the Fanuc 50 way ribbon cable which goes to the BTR.
As you may have read the reader electronics in my PPR look to be dead.
However, probing signals in the PPR box does not look trivial : poor access, no
schematics and the

I was just wondering if I was the only one. It may have been through someplace
else I've been at.
I just wanted to send the warning. I've seen 3 in the last day.
I must be on someone's list.

The IMI 7710 34 pin flat cable interface is a variant on the SMD dumb interface
which could be controlled by a UDI (universal disk interface) if someone cared
enough to build an adapter and then program the UDI to deal with IMI's specific
track format and peculiar command/status protocol.
I've been getting a bunch of "release of lien waiver"

I've not been opening the click bate. I'm just wondering if anyone else is

What, on this list? I haven't seen any of that.
I get a large amount of dishonest mail; much of it is caught by my "send this
immediately to trash without reading it" filter rules. Like you, I have no
idea what's attached, simply because I have no interest in investigating the

Some (if not many) of those that do eventually learn how to do it still

They are if you’re someone who has a machine using one of these interfaces, or
e.g. the 40-pin “IMI bus”, or whatever else.
I'll only mention that there were ICs that could interface to both
MFM/ST506 hard drives as well as floppies (System/3 MFM).
An example would be the SMC HDC9234, "Universal Disk Controller".
Pretty cool chip for the time; has full 24 bit DMA address capability.
But different register/controller
. . . and, if there is agreement to standardize the connection system for
the "personality modules", then some of the other storage systems could be
implemented, particularly including some of the tape systemmes.
'course, it would be a lot more fun, instead of the 62 pin card edge, to
go
