Yesterday I surprised myself by managing to dump half the ZX81 ROM by wiring it up to the Tl866ii as a 2732 instead of a 2364 (which the TL claims ignorance of and I can’t hack it in because the firmware is encrypted).

I say half because I should have been targeting the 2764 but got confused because the 32 is pin compatible (a DIP24 instead of DIP28) but I honestly wasn’t expecting my method to work so it’s a huge success and I know what I need to do to get the rest.

I was surprised when I didn’t get a dump of 0xffffs and even more surprised when the data wasn’t garbage and actually disassembled to Z80 assembler!

Starting to look like the ROM isn’t the reason it won’t boot which is kinda exciting!
