i buy this 2 sram chips only(NEC D431000ACZ-70L) for my trinity v3 for C&D bank and extra 64 preset to M Bank.
i waiting to pick(is ship from U.S to Greece).
but I want to ask:
when I should put the sram.. the first thing before open the power i do will be the reset? ie i open the power to on with the holding ENTER + 0 button with the disk in to the flopy(2 disk with OS 3xxx?
and install again the os Vesrsion 3.xxx?
First of all, save everything to floppy disk, all of your PCG data, as you will lose it by doing a factory reset.
Shut down the Trinity, unplug from the mains electrics. Open up the Trinity, ground yourself and the Trinity by briefly touching an earth connection (such as a radiator in your home, if they are earthed). Carefully (and I mean REALLY carefully - those legs are too easily bent) insert the chips into the Trinity's motherboard in the correct orientation (with the indent on each chip pointing inwards).
Close up the Trinity, and hold Enter + 0 when you switch it on. This will wipe the Trinity's memory. You do not have to re-install OS v3.xxx again.
Then take a look to see if you have C & D banks.
As mentioned, if you don't have the PBS board, I'm not sure if the chips will work alone, but it's worth a try.
