Kirk IMP-16 Homebrew System
The Kirk estate donated this IMP-16 homebrew computer and it's in MARCH.
The photos were from my phone, so they're not as clear as a regular camera.
I also don't have a photo of the 16-bit IMP-16, nor the ROM card with two
of three 2708 slots filled. The two RAMs are full of 2102's. Based on the
dates of many chips the system appears to have been built in 1978 or 1979.
Note the pic containing a view of the MARCH inventory on new shelving
units. Evan, Jeff, Elise, and Jeff, and everyone else - great job getting
our inventory organized. Its great to see.
I took home the Mark 8 replica, let me know if anyone here'd like to get
together to build it at my place and/or InfoAge

Several things impressed me about this prototype:
- 7 segment LED displays instead of individual leds
- instead of toggle switches or a keypad,
he used 4: octal thumbwheels with speed levers
for entry (the lever is 7 on top, 0 on bottom)
- but not even Dymo lettering for the other switches
We need to further ID the CPU and major chips.
Can anyone identify the backplane and cards used?
I've never encountered such long thin cards
with the edge connector on the short-end.
Many are protoboards with generic patterns
for soldering chips and power busses.
The backplane LOOKS like a 2-section DEC PDP
but it's single sided edge connector,
wire-wrapped on the bottom.

had deeper cards like that but I've never seen deep cards with the single side
