The Memotech MTX Series
Memotech Multi-Function Expansion System
This page was first created as a
placeholder when Martin
and I were planning to develop a CFX-III.
This was going to be a development of
CFX-II, intended to improve
the quality of the graphics output. Whilst CFX-II worked well, the VGA
output was not all that I had hoped, with some "noise" being
displayed on some, but not all, VGA monitors and I didn't feel
comfortable making more than the original batch of 10.
For various reasons, Martin and I
rethought the aims of the project and decided that, whilst a
Compact Flash based solution was still a possibility, the waning
popularity of CF, the increasing prices of CF cards and the lack
of a built-in CF interface on most PCs meant that SD card was really a
We have now developed a different
expansion board for the MTX which includes additional functions
and have released it as the Memotech Multi Function eXpansion
card - MFX.
