Forget MAME; I'd love a forked project for this minus the shaders for old machines. Where you just get the terminal emulation with a good TTF font and that's it. There are similar projects for the Altair 8800 where they scrapped their code from SIMH (now I prefer simh-classic) to just emulate a CP/M 2.2 Altair machine and that's it, because these people don't need to emulate PDP10's with ITS, old BSD's, current VAX NetBSD releases or the rest of the DEC machines...
