Greetings from Athens, Greece,
I just bought an EMAX 1 SE (keyboard) with a dead drive, but it seems that an HxC emulator will not solve it that simple…
I installed an HxC, plus I tried swapping the floppy drive from my SP1200 but I keep on getting the same diagnostics cycle when trying to load software: all diagnostics lights are flashing on each read cycle. Bear in mind that if I don’t try to load the OS, no light is up (diagnostics come clean).
My next search was inside the keyboard to check on the IC 1772 (disk drive controller) and this specific chip seems in a dodgy state, like someone already tried to remover & resit it. Additionally, my search showed that quite a lot of different actions (like the use of a wrong floppy ribbon) could also cause damage to this chip.
So, my obvious question is: where can I source one such chip to replace mine? I’ve seen that the EMAX shares a lot of components with the Ensoniq MIRAGE. Could a swap from a Mirage do the work?
Has anyone seen this problem before?
Thanks in advance for any help!
