All buttons and lamps work like on a real PDP8. The switch register has a little extra feature that you should find out by yourself.
Preloaded in the pseudo-memory are:
Binary loader: start address 7777 with sreg at 7777 for TTY. (see VT100 for input)
RIM loader: start address 7756
Binary punch TTY: start address 7465.
Be sure to start with AC clear. (see VT100 for output)
First halt number of blocks. Each block: first halt: beginning address, second halt: end address
Echo routine: start address 0600. Use it for testing VT100 with data form VT100-Tests folder.
Real time counter: start address 0400. If your processor is fast enough, this routine will count real seconds in the MQ. (PDP8 emulator is running at real PDP8 speed if your processor is fast enough)
