Dual 3.5" Lisa??

Posted by: CelGen on 2013-02-22 19:06:11 I have a Lisa 1 that was upgraded to 2/5 and has the H/A8 ROMs but while doing troubleshooting I managed to glitch out the floppy controller and it gave me this: Is this just some artifact that was hidden away in the ROM or is this me poking something in the new ROM and activating some unimplemented configuration? The drive slots for both the twiggy and the 3.5" Sony drives look somewhat the same.

Posted by: CelGen on 2013-03-16 23:19:53 CPU board is 341-0176-H, 341-0175-H, and 341-0229-A with the resistors removed on the I/O board. My I/O board is still being repaired to fix battery leakage so sometimes the COP and surrounding glue flakes out.
