An octal latch goes there. It latches half of the address sent from the MCU.

You can get one from Fry's or possibly a local electronics shop.

Or I can send you one for a couple bucks. PM me.

the 74hc373 are octal D-type transparent latches

from what I gather this chip basically reads, stores, and sends information of the 28 pin eprom/eeprom. It needs to be there for the 29c256 or whatever eprom/eeprom you are using to work.

Edit: you beat me to it, lol.

I know *cough*moates.net*cough* has them for cheap, sorry xenocron.

I guess xenocron has em too, here's the link
