Mr modnaR Posted January 24, 2007 Report Share Posted January 24, 2007 i'm looking for an EEPROM replacement for the EPROM type: mbm27c256a-15.is this possible at all? does anyone know what those numbers mean? i've gathered that the 256 part means 256k of memory, but unsure of the rest.thanks in advance for any help.

AndrewMartens Posted January 25, 2007 Report Share Posted January 25, 2007 As you've probably figured out by now, it's a 32 kB (256 kbit) EPROM, -15 indicating 150 ns access time.It may be possible to find a compatible EEPROM, but the pinout is usually slightly different, as the EPROM has a program voltage pin, and the EEPROM will have a R/W pin. I'm guessing that you have an EEPROM programmer but not a UV eraser and EPROM programmer? Quote Link to comment Share on other sites More sharing options...
Mr modnaR Posted January 25, 2007 Author Report Share Posted January 25, 2007 well, i've actually got neither, it's just that EEPROMs are easier to work with etc. general laziness really. i think the problem's resolved itself now though, the EPROMs were for the Akai S950, and i've managed to track down the SCSI enable OS in bin file form, so just emailed an audio equipment service centre to ask if they can burn a couple of EPROMs for me. cheers for the info though.
