Hi,
A quick question raised by my ongoing work....
Is it possible to write directly to the "display register" - the one
YEs, it certainly is. I've done it many times.
accessed by one position of the data switch. I think
it should be at memory
location 777570, but I can't get data into it, either using deposit from the
console, or moving data under program control.
I can't rememebr if you can deposit to it from the console, you can
certainly write to it from a program. The address is the same as the one
you read to read the state of the switches -- 777570 sounds right.
