Buying a G540 programmer
I have been collecting old EPROM chips for many years. Now I was curious what data these hold exactly. I am not looking for program data but more for character maps, hidden “Easter eggs” . Something like this Hack a day ((Hack a day on hidden photographs in old Mac ROM chips )) post.
So I went to ebay an bought one of this widespread available “Genius G540 ((G540 programmer on ebay))” EPROM programmers.
It came in a cardboard box and this were the contents
Of course I could not resist and opened the programmer.
Too bad I noticed the seal of warranty only after screwing the programmer back together.
Now to the software installation process.
I refrained from using the drivers from the CD-R and instead downloaded them from the stg51 website ((Driver & Software download page on the stg51 website))
The installation instruction is awful but it gets to the point and I had no problem installing the software. There were even (unsigned of course) x64 drivers for Windows.
Testing the programmer (reading an EPROM)
To test the programmer I picked an 512 kbit EPROM from an Auerswald PBX.
