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 cannot access the SRAM.
A15 never changes from LOW.
It is as though I cannot access anything except the internal MCU
locations. I can read/write EEPROM ok.
1) Is it possible to access external SRAM from PCBUG?
2) Shouldn't one be able to control the port data from PCBUG? I've
tried but get BAD ADDRESS (or BAD MEMORY something like that). Like
it's not there
3) Still would like to know baud rate in boot mode?
4) Is the LCD manual on the web somewhere? Maybe I'll play with that
tomorrow.
Looks like I'll have fun tomorrow playing with this.

| I have assembled the HandyBoard up to the point of adding the SRAM. I am still waiting for my SRAM to arrive. But, I want to check out as much as possible. Every step checked out fine to this point. I have two options at this point. I have an 6264 (...) (27 years ago, 2-May-98, to lugnet.robotics.handyboard)
