So using similar settings to the BBC in FF.CFG, and plugged into a Watford Electronics external disk interface it works great as a second floppy drive.
Code: Select all
interface = shugart # or jc with JC link open host = acorn
So, I thought, can I connect the Gotek/FlashFloppy directly to the Arc motherboard?
Well, it appears that on the A310 Acorn swapped the rows of pins on the SK11 FDISC connector SK9 so that pin 1 is swapped with 2, 3 with 4, etc.
Therefore to work correctly an adaptor is needed. The pin numbers in the A300 service manual look correct but don't match up with real pin numbers on the physical connector.
On the A400 series schematic the whole connector is reversed so Shugart pin 1 becomes A400 pin 34.
This should work if the cable is reversed but I don't have an A400 to try.
Has anyone else noticed this?
