longtime since I've done this, but I think it's just a prog rom change, IC17/IC18 - but it's been years and I've slept since then.

I know jodo has/ had a rom board of each so might be worth asking him perhaps, he won't mind you picking his brains I'm sure.

128kb roms, so 27c1024 is the correct type.

Just wipe the vF2 prog roms and reprogram with the 2.1 ones, simples.

Another option for you is to contact Steph on hobbyroms.com (it's how I did mine)
If the AM 27c1024 eproms are in stock it will cost you about 32 dollars including postage.
you will need to email the 4 files to steph
epr-18385.12
epr-18386.13
epr-18387.14
epr-18388.15

I have these 4 files on an email, if anyone wants them send me a pm.

Phil.
