    Default 27C400 eprom chip

    Hi all, anyone have a spare 27c400 eprom chip for sale. I need it to program a unibios for my neo geo cd. I did order sone from China from 2 different sellers last week but they've both since cancelled my order and refunded claiming the chips are bad.

    Ideally id like it sometime in the next week so I can try and get it programmed and fitted before geekfest next week so uk or Europe would be preferred.

    Thanks

    Are you sure the needed eprom is a 27C400 and not a 27C1024 ? I have several atmel OTP ones from when I changed the BIOS on my jamma neogeo , if it works for you then I can send one over

    edit: oh I just found some adapter for CD systems that indeed needs 27C400....

    Hi guys, I have found one from tbtorro and sent him the cash over.

    @zetro, thanks buddy, I think I'm sorted but if not you'll find a pm in your inbox.

    @keropi, yeah I've done the bios on the aes and mvs in the past but the cd needs a 27c400. I could buy a preprogrammed rom from razoola but it was nearly half cheaper to buy the rom image and burn it myself plus he emails me a rom file when there is an update and I can just erase and reburn the chip. I do have one but it's currently in use as a region free bios in a very early sega Saturn. I have a few 27c1024/2048/4096 but thanks for the offer.

    Forgot to acknowledge that I received my chip from tbtorro a couple of days ago. Will close the thread
