Nah, it's the COVID. The mail is reaaaally slow now, in fact I have now switched to shipping everything via UPS.

I can confirm buffered ide works fine with pin1 lifted and tied to pin2 on IC6.
Thanks Stephen :)

I seem to have an open circuit in the board as I have no connection between the STERM CPU pin and any pin on the CPLD. Pins adjacent to STERM such as BERR and DSACK1 do find their way back to the CPLD.
On unpacking the board when received, it had a scuff in the solder mask in this area and between the 68K pads. Checking over with the microscope before assembly did not reveal any open circuits, but I guess there was something that was missed.
Could a schematic or boardview file be made available to assist with tracking down the fault? Thanks!

Thanks. Will dig into the board a bit later and hopefully get to the bottom of the issue.
