Mike,
I used PCBUG11 to test my handyboards. The reason that you can not access the
SRAM is that PCBUG11 boots single-chip mode and there is not external bus. You
need change HPRIO from $85 to $A5.

| My problem turned out to be with Win 95. If I boot to DOS the PCBUG11 program works fine. It fails to work when working from a DOS window. I can now communicate with the MCU so my RS232 must be fine. When working from the command line in PCBUG, I (...) (28 years ago, 2-May-98, to lugnet.robotics.handyboard)
