Dragon ROMs

Hi All,

Long time lurker here. I had an account but I guess it expired.
How do I read Dragon ROMs in my EPROM programmer?

My GQ-4X supports every device under the sun but not the TMS4764.
Any tips?

Welcome to the Archive!

It seems that there's no direct eprom equivalent for the TMS4764, but there's the possibility of building an adapter to a 2764.

Do not try to dump it on a programmer or you'll end up frying the chip!

What is it that you're trying to dump? If it is a Dragon cartridge, you'll have more luck saving the rom memory area with CSAVE to a wav file on your computer and I'll take care of decoding the data out of it.

Cheers,
Rob

Thanks Rob,

Just toying with the idea of a custom ROM.
I have a bunch of 27xxx EPROMs around here. Would be simple to make an adapter.
