I don't think anyone is *producing* an option rom board, but there is a board up on OSHPark that anyone can build themselves. I have built a few. They are easy and cheap to build.
And they are re-writeable, although you need an eprom burner and a test-clip or a special programming adapter to re-arrange the pinout, not just software like rex or a flash drive. But the burner is only $30 or $40 and the software is free. Maybe Ed Snider would be willing to build them for people? They are dead easy. https://goo.gl/photos/Zs8ZnmDco9BwgDDBA https://oshpark.com/shared_projects/LfdyAK6a There's a main rom adapter too. https://oshpark.com/shared_projects/toQDqmVV https://goo.gl/photos/GUKXgxxVGaUVt57k9 More details. I wrote a lot in a big comment on the option rom, with links to parts and tools to build and program both. option rom https://m.facebook.com/groups/1186716131388896?view=permalink&id=1215063315220844 main rom https://m.facebook.com/groups/1186716131388896?view=permalink&id=1207682412625601 I'm not "FigTroniX". I just worked with him to develop these until they actually worked. I'd love a REX too, but if I can't buy one or make one myself, or FIVE, since I have 2 100s, a 102, a 200, and a 600... -- bkw On Jan 6, 2017 4:55 PM, "Kurt McCullum" <[email protected]> wrote: > I wasn't aware that Steve stopped producing them.
