What's that you say? Simply re-flash the

the "special cable" that connects to the back of the drive?
Easy enough if you have a 4-pin connector on the back.
It's standard RS232.
Of course, I have to have the older 3-pin model,
which is TTL, and needs a leveling adapter. . .
Two options. No, three actually.
1) get a single-chip RS232-to-TTL converter like a MAX232
2) (the third one I thought of) get an el-cheapo USB GPS. These have a
very handy little USB-to-TTL serial interface in the screwed-together
blob in the cable. The GPS speaks TTL and the CP2102 interface turns it
into a USB serial port.
3) Get a serial card. Break TXD and RXD out from the UART. Bring it
out to a socket. (I did this, and changed the 14.<something> crystal
for a 16MHz crystal so I could make a 62500-baud link to talk to a
synthesizer display).
