Some drives can be jumpered to output the desired /RDY signal, some can at least be soldered. Others can be operated by "tuning" the cable.
See [[3 1/2" & 5 1/4" Disk Drives]] for more detailed instructions, incl. Side Switch.
== Aleste 520EX Disc Connector ==
The [[Aleste 520EX]] has (almost) the same 34 pin male card-edge as the CPC,
A1..A17 Same as <odd> CPC Pins 33..1 (NC,NC,NC,/INDEX,etc) A17 ------ A1
B1..B17 Same as <even> CPC Pins 34..2 (all wired to GND) B17 ------ B1
The drive select signals are a little different:
CPC.Pin23=/DRIVE_SELECT_1 ALESTE.PinA6=DRIVE0
CPC.Pin25=NC ALESTE.PinA5=DRIVE1
