Strangely enough... it's the VT103! Had optional
dual drive TU58 mounted
under monitor (got one, gotta replace the rollers with tygon tubing).
I think I also saw one a _couple_ of years ago that had dual floppy
drives on top of the VT1xx box. Is it possible that there was something
like a VT180? Or was it the "Robin"? - Too long ago. "Dave ... my mind
is going ... I can feel it ..."
I still have to connect a TU58 to my home-grown Motorola 6809 and put a
little RT-11 file system knowledge into it's boot EPROM. That would
allow me to use MACRO-11 as a development platform... - Different
project...
I haven't been so lucky to run across some of the
third-party DEC stuff.
Most of my Qbus collection is straight DEC. One card I have that I wish
I could find docs on, looks like a Systems Industries(?) CS-1 SCSI card.
It does not live at any of the usual MSCP-interface addresses. Beyond
that, I suspect it's a tape-only interface, so perhaps I didn't look
where a TMSCP device lives.
If it's a tape interface, then, yes, it will have a different CSR
address. Most of my collection - if you allow me to use this word in
this place - is also straight DEC, even my microfiche viewer served a
DEC technician in it's (the viewers ;-) former life. So I cannot be of
much help with this board, sorry!
