The Holiday break has given me some quality time to spend on a single board computer using the IM6100 (actually Harris 6100.)
Got the PCBs earlier this month and was finally able to get one assembled.
Control Panel is nothing but switches and LEDs but for me was the most difficult part.
I plan to post all design details on Github once I am further along.
Also have extra boards and parts (including switches and LEDs) if anyone would be interested in the future.
At this point it is passing the processor and extended memory maindecs.
The serial port on the SBC serves a dual function as the KL8E compatible port and also as a debug port.
It is very useful as a debug port since I can trace program execution and print the bus contents for every memory cycle (R/W/IOT)
The SD card is FAT32 and contains disk images which may be assigned to either drive of a dual RX01.
I am currently working with the RX8E maindec.
My plan was to NOT implement the deleted data function.
Does anyone know if this bit is actually used anywhere (besides the maindec)?
