Lear Siegler ADM3 terminals

These terminals are very nice; I have a brown one and
a blue one. One part that always breaks or is missing
is the flap on the front for the DIP switches. I made
aluminum plates to fit in the recess.

Both of mine had seriously burned in CRT's; I put in
new ones I got for about $40 each shipped (I hate this
kind of work, but I did it) and now they look and feel
new. I opted for B/W for "originality", although I
could have gotten green phosphor at the same price.

One didn't have the lower case option; the chip for
lower case is hard to find. So I copied the ROM out of
the ADM-3 with lower case (2kx8, strange voltages and
pinouts, a 2513-type ROM), blew a 2716, and made a
little adapter to plug into the other ADM-3's 2513
socket. This, two 2102-1 RAMs, and a few flips of dip
switches gave me lower case! Absolutely hideous
matrix, but very authentic!
