Hi, Great website - Lovely to see someone else equally passionate about retro computing hardware 🙂 I was hoping you might be able to share with me the modifications you made to your original Yamaha CX5M SFG-01 pcb to allow it to run the later SFG-05 ROM. All the best, Dani.

Hi, It was a while ago I did it, but it's a fairly simple mod as long as you have some soldering skills. Basically you need to replace the EPROM chip by unsoldering from the board, fit a socket in its place, and then plug in the new EPROM (but with one of the legs bent out. You can get pre-programmed chips off ebay or if you have an EPROM programmer then burn you own onto a M27C256. After this there is one wire you need to run to one of the legs on the new EPROM. There are a few YouTube videos that go through the process, this one for example: https://youtu.be/535lS1rKleM
