[Coco] About those EPROMS...

[Salvador Garcia]

Hi all, I’ve been reading the discussions that talk aboutEPROMs. This got my curiosity going. What reference material is recommended tolearn more on how to interface an EPROM (family 2732/64/128 etc) ?
For example, if I want a dump of its contents, how would I goabout that? I found this instructable:
http://www.instructables.com/id/EPROM-reader/
However,  I would hopeto find something better as it is not my idea to address the EPROM one addressat a time! I searched for the pinout and it seems rather simple. Only threecontrol signals: /PGM, /OE and /CE. For normal use keep /PGM high and to readget the address on the bus and bring down /CE and /OE. The documentation doesnot specify what the difference between these two signals is or what happens ifI tie them together and just bring them down at the same time. It also does notmention if these inputs are high (or low) if not connected (or HiZ); I wouldimagine that they would be high.
Any pointers on where I can find reading material to learnmore about these ships is appreciated. In the meantime I'll continue looking. Thanks! Salvador
