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
