The Machine Room is Back!
This is the recovered Machine Room from 2005. Please don't expect wonders. The look and feel of this site is nine years old, and so is its code. Some of the functionality has been recovered while the rest of the site is modernised and restructured. Watch this space!

A nice implementation of the Z80, with Texas Instruments support chips. You could easily spot similarities between the MTX machines and the Sord M5, Tatung Einstein and, of course, the MSX standard.
