in chapter 5.1 (pdf page number 48).
To do basic memory read and write:
Press MD and DISP (memory data register will be displayed on the four digits)
Then press 0200 and LA (load address)
Press 5050 and D-THIS (deposit to memory on this adress, no increment).
Press E-THIS (examine on this memory address, no increment) and you should
get the same result back.
Another good place to be is to post in the DEC category on the VCFED

Hello everyone - my first post, so be easy on me!
I have just acquired a PDP8/a and a Remex punch tape reader. The unit
starts up and displays some data on the displays, and that is about all
I can tell you.
I am going to do some googling about this, but I am looking for basic
initial tests .... something I can enter via the keypad.
I learnt some basic programming in 1978 on a PDP8, but that was the last
time I touched one, so if you are going to suggest some tests, I need
complete instructions. I don't know how to modify a memory location, let
alone enter and check a program. I will pick all this back up very
quickly and I do use computers in my work a lot - I am also an
electronic hobby guy and have been for years. My point is I am OK with
component level measurements, I have a scope and probes, etc.
So there you go - hope to hear back form you guys.
Cheers,
Brian
