I'm trying to get a MONO Cube I have here back to
a complete box.
Missing is the
- Floppy Drive 2.88 Sony and Bezel
- mounting Bracket for the Drives ??? The large piece
above the Power Supply is there. I would guess it had
something to hold the 3 1/2 drives.
- no Optical drive or cover. Not Sure it had one ??
- no expansion slot covers. Rear cover is there.
- mouse is missing
This is a 68040 25 built is 1991
Looking into the 2.88 floppy it looks like there was
no standard for the connection on the different makes.
So either I have to use a sony or make a adapter

Hmm... A real IMSAI is what, 10.5" tall, 19" wide, and about 24"-36"
deep? That sounds difficult to reproduce at 1/12th scale, but it
might be possible to replicate an IMSAI front panel with fiber optics,
run them under the floor of the doll house to a hidden Z-80 board
(that could still be done with a lot of SMT to make it small).
It comes to mind that a microSD card is on the close order of the
dimensions of a 1/12-scale 8" floppy ;-) (2/3" x 2/3")

In the quest to get my new VAX 7640 up and doing something useful, I'm
looking for an XMI DSSI card and cab kit for the system, so that I can
have *some* physical media on the machine.
I've got a bunch of random DEC stuff available for trade, including some
XMI CI interfaces which I doubt I'll ever use (famous last words), QBUS
stuff, Alpha stuff, etc. etc. Or, cash.
I mostly want to avoid spending the $big_num that ebay sellers want for

Agreed - I am sure this has cropped up on the list before, too, with the
same conclusion. Venus shouldn't be a problem; there are plenty of
possibilities about, ranging from sports halls to places the size of the
NEC; although you'd need big pockets for the latter.. Just pick a size
and go from there..
A reference was made to MicroNova. Like Data General MicroNova? Like the MicroNova that?s in my lock up, that I haven?t
run in 15 years? Like the MicroNova with the 16 or 32 serial ports, I don?t remember, for terminals? Like the MicroNova I lost
the 10M washing machine platter drive from? Then threw the removable platter out because I couldn?t find the washing machine?

I believe you're thinking of the book "The Art of Digital Electronics"...I
don't remember who wrote it. I too have been considering building an 8/i
compatible, and wouldn't mind some insight.

There is _lots_ of software for that platform, of course. The PDP-8
has a rich history.
I've been re-reading a book on processor design I picked up a few
years ago, based on a recommendation on this list. I am blanking on
the title, but it describes a 74183/74181-based F20 and a 2910-based
microprogrammed F30 PDP-8/i-compatible CPU. I've been mulling over
what it would take to build one of those (besides lots of time ;-)

Hmm... that does sound interesting. A 320x200 LCD panel isn't
expensive (I have several raw ones on hand w/touch sensors), and could
be driven to 80 cols w/a 3x5 font (as was once used to give the C-64
"80 columns"). A "really cheap" terminal could be an older Palm Pilot
running one of the extant terminal emulators, sharing a new enclosure
with the PDP-8 board, attached internally via TTL serial.

I think a 12-bit hand-held would be pretty cool.
