Re: Anyone have the wiring for m27c160 chips

Just wondering if I should even bother wasting my time using these chips on snes carts? With 27c160's? They are the only way you will get more than 1mb with a single chip unless you use TSOP. 27c160's are great cause all you have to do is shift over 1 address line and use D15 as A0. D0-D7 are used ...

Would have thought it was obvious this didn't use any ram.

There's certainly a place for the donors .... Like the no SRAM, basic pcb that just has 1 rom. But if you game requires SRAM, mine is a pretty good alternative.

Re: Markfrizb's new SNES pcb's, you need them now!!

Might be good for a dev board or test board, but I don't see these replacing sports games/Japanese horse racing games as donors. First of all, I get a free shell for each game with the purchase of my crappy 4 for $9 deals from Ebay. If you can get 4 for $9 I'd love it if you shared these deals :) E...

Markfrizb's new SNES pcb's, you need them now!!

Hey Guys, I just wanted to give a quick shout out to Mark's new SNES pcbs. These things are like a swiss army knife SNES board. They can do pretty much any game, multigame, hi\low\ex, combos, all the logic is built right on the board so there is no messing around adding 245's or 139's or SRAM cause ...

Re: 29L3211 on Sega Genesis/Mega Drive 16bit

I get sick of using 27C322 (4MB) EPROMs and erasing them all the time when I want to program something else, not to mention they mostly fail to erase themselves.... That is why I ask you if I can somehow use a MX29L3211 chip on Sega Genesis?? There are some SOP44->DIP44 adapters available here: htt...
