If you would like to work on it, your help would be welcome. I plan to draw the schematic but it may be some time before I get to it. I reassembled the board and the computer no longer crashes. When it is activated with SYS 59904, the ROM displays the banner and attempts to boot the disk. I have a disk but it is in poor condition. I have not been able to try it yet because I need to repair the cables first. Lee Davison did an initial disassembly of the ROM that is now linked from my page. I have been working on it also. The ROM contains code to read/write sectors and possibly the LOAD command. The remaining functions are in RAM.
