Subject: [p2k] Any interest remaining in a self-programming FLASH SIMM?
Couple years back I started a project to build a FLASH based SIMM for proteus 2000 systems that acted like mulitple SIMMs at the same time. Basically you could put this one SIMM in one socket with the others empty and it could look like you had SIMMs in all 4 sockets. I got pretty far along the path of making it (even getting some PCBs made) when I discovered that I had the pin outs of the microcontroller (that allowed you to program the FLASH devices via a usb connection) wrong and the at the boards were just scrap. I posted a picture of the boards in the group. I was annoyed at myself so I dropped the bundle.
Well... I was thinking that the idea is still sound (though I wasted a lot of $$) and I could finish it off if there was sufficient interest in the thing.
What good is it? Well you could have any four ROM SIMMs in you system that you choose. You could reprogram it as you want. And in theory (if we can decode the format of the contents - shouldn't be too hard) you could author your own ROM images and download them , then create your own presets and hard code them onto the device as well. It would be a bit of messing about to achieve the results but if people are prepared to put in the effort...
so is anyone interested?
