Product Overview
Perfect for the Do-It-Yourself vintage machine enthusiast, this unit converts the MOS 2364 or Motorola 68764/68766 pinout to a JEDEC standard 2764-27512 EPROM pinout. The optional 3 high address lines are available via pads complete with provision for pullup resistors (10K).

4 Works great, just make sure height is not an issue
Posted by William Murray on 2nd Jul 2021
The adapter works perfectly with 2764, 27128, 27256, and 27512 (as well as with CMOS and EEPROM variants). Only reason I didn't give it 5 stars is the fact that it's a bit taller than I expected, as the pin headers on mine weren't soldered flush to the board, but sort of stuck out. It was nearly too tall for my application, but just fit. I recommend that the seller take a picture of the module's height, so that people with space limitations be aware.

5 Great product at good price

We buy both the assembled and unassembled boards. We need a very low profile for one product and so build our own with pins to achieve a lower profile. Both are great.

Worked perfect, good construction. Used for an Eprom for my C64 Kernel.

5 Terrific solution
Posted by Chuck Hutchins on 11th Jan 2019
I had to replace both failed ROMs in my CBM 2031. This worked perfectly to easily adapt a D2764A to the 2364 8K ROM sockets. I'm sure I'll be using these again on other restorations.

5 it works!
Posted by Rok Kozelj on 15th Nov 2016
the adapter works! I replaced a ROM character generator in an original CGA card with my fonts (glyphs), putting a 27C256 on the adapter, and inserting the adapter in the CGA slot, and it works perfectly.

5 Adapter for 28 pin Eproms to 27C512
Posted by Hodan Wolfgang on 29th Oct 2016
absolutely good quality, perhaps a precision socket would be possible. THe price is also OK and it functions perfectly also with switches. (4 switches for an 64K Eprom.)

4 Excellent product if you have the space

Would be five stars if thinner so adapted chip could fit under the RF shield in my application. However, it seems to be high quality and works fine.

5 Very Professional Design and Construction
Posted by Unknown on 23rd Jan 2015
This adapter is very well built with quality parts. I use this adapter to permit newer EPROMs to function in the SYM-1 series of micro-computers as either system ROM, BASIC or Resident Assembler/Editor ROMs. A great cost-effective way to expand the capability of the standard SYM-1 that just had the system ROM when sold.
