This, and also, which sizes do you have? Are there any 16 bit EPROM?

Sorry for offtopic

, I have some 16bit UV-erasable EPROM's, but they are small, something like 32k*16bit or 64k*16bit. PM me, if you interested, i will check for more details.

Part number? I didnt know there were so small 16bit EPROMs xD

Perhaps the BIOS of a system with a 16-bit data bus might use a 16-bit EPROM. How small is the TMSS mask ROM in the Sega Genesis? How big is the ROM in a Game Genie for Genesis?

i took them off some sort of controllers with 80186 MPU onboard. Couple of them 100ns and couple 120ns. Should be some other, but i have to dig deeper into boxes with parts.

Sorry for offtopic again. About TMSS ROM - some sources saying it's 2kB, but i never saw one in real. Well, at least in Sega's made before 90

WoahMan: I could use some 27C64, I was thinking of trying something with the VS Unisystem, but (without making a daughterboard) it uses 6 ROMs for a normal sized game.

27c64, 27c128, and 27c256's are what I am offering.

Ill take 1 or 2 trays of each, so 14-28 of each size depending on postage to Canada.

Thank you very much for this offer.

It's great to have such a large quantity of EPROMs but unless you release a game which would also sell in very large quantities this is not very useful...

Don't worry I'll be using them.

Alrighty, It is now sadly time to close the offer so I can save the remaining for my junk shop. As far as anyone who said they wanted some before this message, I will still ship some out your way for the shipping costs listed earlier

I just wanted to let you know I received the eprom today. Thanks again for your kindness, I have never seen so many brand new 27c256 in my life and I got to say that I never ever saw the small official Mitsubishi Electric sticker for the eprom window!

Im glad they arrived ok. USPS has a bad habit of not updating tracking information and half of the time i checked on the ones i sent out, they had no info. Your was one of the ones without info.
