Cindy,
CoCo's have linear PSUs so you could soft power up using a variac, but I
can't think of anything special to try

Tried that one out too, and it works. In fact, unlike my M8017, it will

You know I miss (A LOT) Palm desktop simplicity!?
Wish I could have the same functionality on my android phone. Everything
was SO simple and straightforward...

L series are combinatorial only. You (or someone who has a working one)
should be able to figure out a logic map by either running through all
the input permutation or putting it in a reader that will do the same
(vs reading the fuse data).

Good luck.

Do you have a schematic that shows what it does. You could write your own file
is not really complicated for a 16L8. I wrote my own for my 6532to6530 adapter
for the KIM-1. I'll admit I did a logic mistake the first time but I'd have
done the same with palasm.

Not so. The 16L8 has feedback connectoionsfrom the outputs to the logic
array. So while there are no registers (D types), you can make SR type
circuits in

Ah, no. (Well, the KDF11 CPU's can boot to EPROM, which in the -11/23+ can be
