I have one of those EME rombo adapters. It’s awesome. But I wasn’t aware that OSHpark was getting into the flexible PCB business. That would be far more convenient than this adapter. I use mine in my 200. I also have the more flexible adapter that Traveling software used that wraps around the Molex carrier. The EME board is definitely the way to go. I think there is even a way to wire that adapter to support 2 option ROMs with a switch attached but I have never tried it. But the small trace and solder hold near pin 1 make me wonder.

I have a Disk+2.0 rom that is a nice simple board that takes a dip28 27c256 too. Though remember these were commercial roms never intended to be re-written. The Figtronix board, not to mention rex, allows the eprom to be re-written. https://photos.app.goo.gl/eoAOXsNE1QlvFi123 -- bkw On Sep 13, 2017 12:51 AM, "Kurt McCullum" <[email protected] <mailto:[email protected]> > wrote: I know there have been a few adapter boards put on OSH park. Most of these user newer Eproms which, from what I have gathered reading the list, are more difficult to solder. I disassembled an old Super ROM tonight to look at the adapter board. It seems like a fairly straightforward board for converting an older 27c256 to the OPTROM pinout. Has such a design already been made available online? Kurt
