Ben Milner I think his name is. Apparently post on this forum??
OR
Does anyone have any details on this mod?
Much appreciated
Do you mean to mod it to XP-ALL? If so, Govmnt_Lacky is doing it.
Look in the layout gallery as well, and search «XP-ALL». You`ll find the build document detailing the process, and required parts. The .bin files for all four XP units are there as well, including the XP-ALL+ file (all four programs on a 27C1001 chip), if you`re planning to burn your own chips.
If you`re not into doing it yourself, then Govmnt_Lacky is your man. He builds the most awesome XP-ALL units, hands down, bar none. Works of art that can do double duty as great effects units, as well as a wonderful conversation piece on your living room coffee table.
If you only need chips programmed, you may contact him, or myself via PM for the service. I can`t speak for him, but I do charge a small fee just to cover return postage.
