I have a spare 1200XL that is completely stock. Reading about the REV 11 OS got me thinking. I have a bunch of 2764 Eproms. I would think it would be possible to program two 8K Eproms and put them in the OS sockets. I have looked and can't really fine a guide that would show how this is done. I have the REV 11 rom file but it is 16KB. I will have to split the file in half (unless someone knows where there is one already in two 8KB files).
What changes to the board would I have to make to put in two 28 pin Eproms (besides soldering in two 28pin sockets)
Thanks,
Sean
