St M27C256B-20F1 32KX8 eprom programmed with your code
ON SALE: I AM TEMPORARILY REDUCING THE PRICE OF ALL OF MY EPROMS TO $2. THIS SALE WILL END IN 3 DAYS (SATURDAY)
This listing is for a ST SGS-THOMSON MICROELECTRONICS M27C256B-20F1 32Kx8-bits, 28-pin DIP EPROM Programmed with your code. I will program this device with the code of your choice of up to 32 kilobytes of code total.
THIS 27C256 EPROM CAN ALSO BE USED IN PLACE OF A 27C128 OR 27C64.
TO USE A 27256 IN PLACE OF A 2764, YOU SIMPLY PROGRAM THE 8K IMAGE (THE 2764 IMAGE) INTO THE 27256 FOUR TIMES.
TO USE A 27256 IN PLACE OF A 27128, YOU SIMPLY PROGRAM THE 16K IMAGE (THE 27128 IMAGE) INTO THE 27256 TWO TIMES.
I ALSO INCLUDE THIS SERVICE FREE - I WILL TAKE YOUR 8K OR 16K IMAGE AND "STACK" IT INTO A 32K IMAGE SUITABLE FOR PROGRAMMING INTO A 32Kx8 EPROM (27C256 OR EQUIVALENT.) I WILL THEN EMAIL YOU THE "STACKED" IMAGE. THE RESULTING EPROM CAN THEN BE USED AS IF IT WERE A 2764 OR 27128. I GUARANTEE THAT THIS METHOD WORKS PERFECTLY - I USE THIS METHOD ALL OF THE TIME BECAUSE I HAVE MORE 27C256 EPROMS THAN ANY OTHER TYPE.
