A question here for Phill (Prime) or anyone else that can help:
One of my CoCo's is a PAL CoCo 1 model 26-3002 with the chiclet type keyboard. It came factory sealed with 16K RAM + Color Basic 1.1 + Extended Basic 1.0. There is a number 20261007 on the motherboard by the power supply and I noticed a couple of jumpers marked 16K - 64K by the eight NEC D416C-2 RAM chips. What I want to know is how to identify which board type (D, E or F) is fitted and how to upgrade it to 64K RAM.
Can anyone help?
