I have been asked what I think about those persons selling my DiagROM on Ebay.
Well Simply: It is OK unless you ask too much. I myself charge 6eur per ROM. (8 if 27C800 for the CD32)
But. I must say, IF you buy from https://gglabs.us/ like on : https://www.ebay.com/itm/2pcs-GGLABS-F2R16-Preflashed-with-Amiga-DiagROM-diagnostics-for-A1200-3000-4000/401500055759
he actually send me some money for it.. so, I would recomend him.. 🙂
