Welcome to the la36 wiki!

Egan Ford wrote greenbar in 2013. greenbar was a printer simulator that ran with xterm. It used MAC OSX for audio, and xterm for vt100 line drawing, color and greater than 132 column support.

I thought that this was a very interesting idea, and took the idea and created la36. la36 also relies on xterm for multiple fonts, vt100 line drawing, color. However, la36 incorporates a select() base data copy loop, allow it to be a true terminal emulator. As well, la36 tracks multiple impressions on the same character cell and converts these overstrikes to bold, underline and strikethrough. la36 does NOT use MAC OSX for audio output -- it uses the sox audio library instead (the command line play utility).

As well, I added file transfer (simulating paper tape reader/punch) either as ASR or manual control. I added PUNMSG.ASM (adding SIO), punmsg.c, readtape.c (the C files can be built with HI-TECH or GNU). This allows us to produce and read paper tape leader.

la36 may be of use with PDP-11, PDP-10, PDP-8 simulators and well as Altair or IMSAI.

I expect that more of this sort of thing will be done in a browser, but having this separate makes it easier to tie into hardware (I use la36 attached to a USB serial adapter, attached to the serial port of an Altair-Duino).
