Tatung Einstein: Console support for the 80 column card (TK02)
Posted: Sat Sep 29, 2018 10:50 am
The Tatung Einstein had an optional 80 column display unit named "TK02" which gave a nice monochrome 80x24 picture using a 6845 chip. You can see it in action (with two screens side-by-side) when you start MAME like this:
mame einstein -pipe tk02 -flop1 SYSTEM80.DSK
For that, you will need the tk02.zip rom file, which was hard to find, but an Einstein owner has dumped it now from his machine.
A manual for this unit (and many other Einstein manuals) can be found here:

("80 Column Card Manual")
You can switch to the 80 column screen by pressing Ctrl-P and Enter, or you can set the startup mode in the Dip Switches menu to "Automatic 80 Column", then this will be the default mode.
FEATURE REQUEST: It would be nice to have VT100 or Generic console support for the 80 column screen too, because currently all output of either console is always displayed on the 40 column screen. Currently only when compiling without any console parameter printf() output is displayed on the 80 column screen.
Low-res graphics should also be possible on the 80 column screen, because according to the TK02 manual, all standard characters should be available when the character set is dip-switched to "Normal".
