Ordering

I anticipate quite a few Memotech enthusiasts will be keen to get their hands on these.

As I've been building them, I've found that sometimes I have to buy components in batches, and sometimes its cheaper to do so. So I have stock of most components. But the GODIL is relatively expensive, so I tend to order on demand. This means it could take a little while to make them.

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

You must appreciate that I have limited skill with a soldering iron. Unfortunately I can't guarantee it won't electrocute your MTX, so you'd use it at your own risk. That having been said, I will test that any board I make works when connected to my test-bed MTXs. Also, I can't promise it'll LOAD and play every game, although I've yet to find a case which fails.

If you would like one, email andy.z.key@googlemail.com and please put "REMEMOrizer order" in the subject line. Tell me your MTX type (MTX500, MTX512 or MTX512 S2), how many ROMs your motherboard has, whether you have an RS232 board, whether you have an internal ROM card and your address. I will make and send one. If you like it, you send me £95. If you don't, you send it back. Either response within a month.

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. Less cost-effective, but possible.

Demand is drying up, so I probably won't be making any more.

Versions

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

If you need (or would like) an FPGA bitstream upgrade, just return it to me, I'll upgrade it and send it back for free. A board upgrade would attract a upgrade cost however.
