Excellent!Just to let you know, your sage advice was spot on
I had some fun with the SEL C - SEL F lines (4 diodes and a resistor to CE) and permitting the I/O "hole" at E800-EFFF (creatively wired up NAND gate to OE) but it all worked
I left the CG ROM in place as it seemed to be running fine as it was. (901447-08). IEEE port working fine now

Yeah, if it weren't for the I/O "hole" it would be really straightforward.
Regarding the CG, once you start actually using it to run programs you may find that upper/lower case is "upside-down".
Have fun!
