See https://mikrosk.github.io/ct60tos/CT60/ ... update.htm:
Do not unplug CT60/63 to program ABE from the Falcon
Solder a 1 to 10K resistor between pin #1 & #10 of one of the three 74LVC245A chips. When launching FLASH060 from 030 mode, NVDI must be running to avoid Blitter to be used by the system ! Now, you will not have to touch the CT...to program from the Falcon // port.

Emphii wrote:Only questions we can make any more, just for the future:
- Should the CTPCI be connected when upgrading ABE and SDR?
- Can upgrade be made, if boot tos is 2.01? (we also tried with version 1.03)
- Does NVRAM battery need to be in good condition? (This one was clearly died)
- It CT60 boot says "keyboard error", but kb works fine, has this something to do with this? (Error could be caused by NVRAM battery or kb wasn't original Falcon kb, but ST/E kb)
