Got some new roms in.
These are for my 8088/8086 the 6502 computer and C64 cartridges.
While I seldom had any problem writing to these, now I could not write one!
Erasing didnĀ“t give me an error?!?

Whenever you get this, check the markings of the chip!
Mine are AT28C64b !!!!!!!!!!!
Change your command accordingly.
Another thing to watchout for is write protect, look at the commands
