It is a 8 Bit, 32 pin EPROM. Ron (r273) Title: Re: M27C400i ? Post by: johnnyt on December 02, 2011, 04:54:38 PM thank you it must be the chip for my wba......i wondered where that went :279-
Title: Re: M27C400i ? Post by: StatFreak on December 03, 2011, 01:25:13 AM The number you posted merely identifies it as a 4 megabit EPROM as r273 explained.
The data on it could be for anything, but since you mentioned having only one IGT machine, you're probably right about it being for the validator. An older S+ doesn't use 4mb chips and an S2000 would use a 16 bit chip (Someone correct me if I'm wrong. :96-) By the way, the "-80" means that the chip is an 80ns (nano second) chip, which is fast enough for all of our various slot applications. |
