I anticipated quite a few Memotech enthusiasts would be keen to get their hands on these.
This is what it costs me to build one :-
| Item | Where | Cost |
|---|---|---|
| GODIL | Trenz | £62 (€72) |
| PCB | Iteadstudio | £3 |
| 512KB SRAM chip | Farnell | £4 |
| VGA connector | eBay | £1 |
| MTX edge-connector | Toby / eBay | £1 |
| SD Card reader module (Arduino) | eBay | £2 |
| SD Card with MTX software | eBay | £6 |
| upto 2 x GAL16V8 | Futurlec | £2 |
| Passives, headers, sockets, etc... | £3 | |
| my expertise, time and effort | N/A | £0 |
| Total | £95 approx | |
Of course, all the project collateral is downloadable, so you could make one yourself. You'd have to download and install Xilinx ISE, download and install xc3sprog, invest in tools (Xilinx Platform cable, soldering iron, multimeter, oscilliscope, logic analyzer, etc...) and run a minimum batch of 10 PCBs.

I have no plans to make any more.
REMEMOrizers are characterised by the board version b and the revision of the FPGA bitstream r :-
| b | r | Comments |
|---|---|---|
| 1 | A non-working prototype, which never shipped. | |
| 2 | 1 | First working version. |
| 2 | 2 (red-spot) | Deglitches the PHI signal (only some MTXs seem to need this).
Shift keys during reset prevent boot to CP/M. |
| 2+yw or 3 | 3 (yellow-spot) | ROM 2 support.
Speculator support. Numeric accelerator. |
This is what the production line looked like :-
