When you get to your keyboard, I used this video to guide me. Mine was full of all sorts of things I don't want to remember.

Now I wish you'd have said something, because I just spent time worrying that I'd botched the job and troubleshooting a non-issue.I didn’t think it was correct when it was stated earlier that the PET would just autodetect the RAM but I wasn’t positive about the universal boards.

Is there any provision for installing this external memory? Did CBM foresee this possibility?… Without it then it’d be impossible to hang an external memory off the bus because the bottom 32k of address space would be locked out, regardless of whether it was populated.
These are the expansion bus connectors. Ram expanders and other devices all connect here and the boards stack above the mainboard on standoffs. ExampleIs there any provision for installing this external memory? Did CBM foresee this possibility?
I mean to say that PETs (or at least my 4016) don't have an expansion / cartridge port as with the VIC & later machines. About the only way to connect it would be to literally wedge it in between the 6502 & socket.
That said, I should probably ask about those two dual male (40 pin?) headers on the right, rear of the board - what are they used for?
