Hey! It's 19 and 1/2 inches wide ;-) But only 7 inches tall :-(
If I ever do it, I might cheat and make it a full 2" wide.
I was hoping to get most of (if not all of) the electronics into a
single chip. The front panel switch size would be in the ballpark of
DIP switches and there are micro surface mount LEDs that I calculated
would fit, a problem might be that they might all blur together at
full brightness.
My wife does doll houses now and then. I have
wondered whether a
fully functional (front panel, that is) 1/12 scale IMSAI would
be possible.
Z80 processor, 64K RAM, maybe a few interesting front panel programs
in ROM... flip the bit, cylon eyes, simple count up/down. Run on a
watch battery.
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")
Hans Franke mentioned the same thing when I shared the idea with him.
