Introduction
Intro Eproms Hardware Software
Time ago
a friend gave me an old TNC2 clone (RF modem) with a Packet Node Eprom on board;
Also having a friend (TNX Pino, I7YTD) who can program 27Cxx eproms, I started
researching informations about eprom on the web for building an eprom programmer
(it was Christmas time so a lot of free time);
After building two different programmers found on the web with negative results
(but I've understand later it was a bad eprom), I decided to project and build
a new one, writing also a WIN9x based software in Visual Basic; here are results:
a programmer for Eproms (27C16 - 27C32 - 27C128 - 27C256 - 27C512 - 27C1001 -
27C2001 - 27C4001 ecc.) wich is cheap, easy-to-build and easy to adapt for other
devices.
But before building the programmer let's learn something more about Eproms.
