Background
This placeholder page was first created when Martin
and I were planning to develop a CFX-III.
This was envisaged as 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
better option.
We are now working on a different
expansion board for MTX which will include additional functions,
so we have moved on to what we are calling the Memotech Multi Function eXpansion
card - the MFX.
Design Goals
-
CP/M Disk system based on SD card
-
RAM Expansion up to 512kB (starting
from 32k/MTX500 and 64k/MTX512)
-
VGA Output for CP/M (80 columns) and
VDP (40 columns & graphics)
-
Network
Connectivity based on the work done for
NFX
-
Utilizing a low cost FPGA development
board
-
Designed for internal mounting
