Mektek C120 reprogramming

[prefabpeti]

Hello all, I've got a Sega Naomi Universal that's fitted with a Mektek C120. It's accepting the old £1 coin and not the new one (as I'd expect what with its age).

Ideally I just want it to accept any coin (in fact generic tokens) - instead of buying the Mektek programmer and looms (£450+), are there any simple options for everything to be accepted?

It sounds to me as if you might be able to swop the coin mech over to a SR3 (mode 1) validator as it’s usually a direct replacement for a C120 or NRI G13. A lot of the SR3’s have a “teach” facility so you can program any coin (including tokens) into the mech. Not all SR3 have a teach facility though. Failing that, could you not simply wire up a small push switch to credit up the game instead?

Thanks, I do have the service button on the Excel 2.2 board which is working - basically I got some Sega Arcade Tokens and it seemed a cool idea to use them if I could. I'm realising now that this coin mech is far more sophisticated than I expected!

It occurred to me to adjust the mech to put all coins to the chute - but I imagine it won't send the signal to indicate what coin went in.

it's not Mektek,
thats a company that sells programmers.

it's made by MoneyControls.
previously known as CoinControls if it's really old.

Good info - I only really looked at the coin mech very late in the process! I've opted to send it off for re-programming (wouldn't be surprised if it's someone on these forums!)
