Ah yes, Facebook again; too bad you couldn't post your no doubt excellent writeups on one of the many sites accessible to the public...
Oh well... ----- Original Message ----- From: Brian White To: Model 100 Discussion Sent: Friday, January 06, 2017 6:09 PM Subject: Re: [M100] Praise for REX 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. Bummer. I'm a bit spoiled already with the ability to save RAM images. Helps with cold starts when I'm testing. Is anybody producing a modern adapter board for the OPT ROM socket these days? I went so far as to disassemble an old EME flexible PCB from an existing Sardine ROM so at least I've got something to add ROMs into another unit but it's getting tough to add these things in. Especially to a 102. At least with the 100 there is the main ROM replacement pcb that can replace both the main and OPT ROMs. Kurt On Friday, January 6, 2017 11:52 AM, John R.

Steve, you did an amazing job! It has made modifying and debugging the SARDOS ROM a breeze. Kurt I agree. I think it's really important that we figure out a way to get them back into production. -- John.
