Memotech-MTX

This was the first and largest add-on for the MTX, it was large black expansion unit which attached to the MTX through a short length of ribbon cable connected between the bottom of the FDX case and the interface connector on the RS232 board inside the MTX. My FDX was fitted with 2 x 5.25 floppy disks and was priced at £870 when I bought it.

Created by Tony Brewer, the Speculator was built into a ROM cartridge case that plugged into the MTX edge connector. Used in conjunction with a supporting tape, it allowed the MTX to run a number of ZX Spectrum games
