EPROM

Listed cost is less then others were found asking and/or simply a guess at what may be reasonable, but with >33,000 semi's there are simply too many to ever determine a cost for each one. E-mail if better pricing is found, for missing costs, to make an offer or if some older hard to find obsolete I.C. is required.
***NOTE:
	Most I.C.'s are USED and pulled from sockets unless they are noted as being NEW Any additional details known about particular I.C.'s will be supplied in my reply to order requests.

EPROM (Erasable Programmable Read Only Memory) has been used for storing simple programs, such as the BIOS, a critical application used to boot up the computer after it is powered on. All personal computers, from the offices of DUI experts to your home machine, have used EPROM to perform this function.
