Hey Bob,
A lot of this is already disassembled in the M100 Disassembly file in my
Personal Libraries section.

Thank you Ken and John.
From John's info that the code for RST 4 starts at 0020h and go up to around
0027h so I can disassemble that to see what happens.
Good stuff!
Bob

But as a quick anwer, RST 4 prints the ASCII character in the A register
to the LCD or Printer.

RSTs are software interrupts. Intel's 8085 manual is a good
source for this stuff, or you can look at this...

Hello,
From time to time when studying others' asm listings for ModelT's, I find
an
opcode called RST 4.
I have not yet found this documented anywhere. What does RST 4 do?
Thanks for your help,
Bob
