Memotech Related Projects

This page provides links to the various Memotech projects that I have undertaken, as well as some old hardware projects from the 1980's. The legacy projects are probably of little interest to anyone except me, but I thought that this would be a good place to archive them.

1. My REMEMOTECH

REMEMOTECH was devised by Andy Key (who programmed many of the games and other software for the MTX series, in Andy's words  "REMEMOTECH is a modern-day re-implementation of a Memotech MTX/FDX/SDX compatible computer". The system runs on an Altera DE1 Development and Education FPGA board and offers the exciting prospect of running MTX / CP/M software on real, non-Memotech hardware.

2. My REMEMOriszer

REMEMOrizer  - to quote from Andy's site, "REMEMOrizer is an add-on for a real Memotech MTX500, MTX512 or MTX512 S2 computer, built using hardware and software developed for REMEMOTECH. . . . .Its like an SDX, only smaller, faster, cheaper and better. This is the upgrade you wished you'd had in 1984." REMEMORizer does not need much help from the user - it works "right out of the box". The only thing you need to do, is to check/set a couple of jumpers on the board and decide whether you want/need to replace the existing MTX OS & BASIC ROMS. There's so little to do that I can't really classify this one as a "Project", but it is a fantastic add-on for an MTX.  

3. My Memotech hardware upgrades & refurbishment

• Upgrade my MTX500 to a MTX512

• Get at least 1 FDX back in operation

• FDX Power Supply Replacement - Using an ATX PSU from a PC

• FDX Disk Drive Upgrade 1 - 5.25" Disks to 3.5" Disks

• FDX Disk Drive Upgrade 2 - 3.5" Disk to HxC Floppy Disk Emulator - ongoing

• FDX Disk Drive Upgrade 3 - Add a Gotek USB Floppy Emulator - ongoing

• SDX Disk Controller - Making use of an SDX bought off ebay without a disk drive

• MTX PC Keyboard Interface - Use a PC Keyboard with your MTX

4. Memotech MTX-512 on steroids? - "MTX Plus" - ongoing

5. MEMU on a Raspberry Pi - Turning a Raspberry Pi into a Memotech MTX/SDX/FDX

6. MTX-Pi - Putting a Raspberry Pi inside a Memotech MTX computer - ongoing

7. Multi Game ROM Cartridge - Courtesy of Martin Allcorn

A low cost alternative to REMEMOrizer - allowing you to run multiple MTX games from a single ROM plugged into cartridge port on the left hand side of the MTX.
