While I was trying to read the ROM in my 9121 for Eric Smith I found out that my Wellon VP-280 could not do it (it could not recognize it and only read FF FF FF FF). I could use it however to dump the ROM of an IBM PS2 that I cannot boot anymore (so it is not entirely useless).
So I am asking what you all use to dump various ROMs from vintage PCs/peripherals/etc? Is there a good brand out there of E(E)PROM programmer? Do you roll your own solution with an Arduino/RaspeberryPi? Thanks, Vlad.
