apple2gs.equ.S at 2.6mhz, 9600baud, I was experiencing lost characters during line scroll or screen clear. To compensate, replace modem polling with asynchronous/interrupt-based code. Up to 256 bytes of modem data can be buffered. 2021-10-24 20:13:06 -04:00

A vt100 emulator for the Apple IIgs

vt100, modem port, 9600 baud, 8-N-1 (MAME defaults)

A vt100 emulator based on The User Guide. Underspecified behavior is tested with MAME's vt100 emulation.

Unimplemented due to hardware limitations:

  • alternate character sets
  • graphic rendition (except plain/reverse)
  • 132-column mode
