Background

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 better option.

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.

 

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 only

 

Mark Heslop (RetroRelix) has done a nice YouTube video about the Memotech MTX which includes demos of MAGROM and MFX. Click the YouTubeVideo link to watch the entire video, or click on the image below to go straight to the MFX review.

 

(Mark purchased MAGROM and MFX from me at the prevailing prices, these favorable reviews were unsolicited -

 thanks a lot Mark!)
