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.

Hello friend.l have these g540 but you can’t type any chips numbers on it. Do you have any one can do that?
How did you install windows 7 64 bit drivers? Works on 32 bit but not on 64 bit machine.
The driver worked for my Win7 x64 computer but I’ve had the same problem when I tried to install the Programmer on an other computer. I haven’t figured out what’s the reason behind this.
Plase I need drivers to G540 for windows 10 .
Hi, because the interface chip is a C8051F340, you need to install the Silabs USBXpress driver. This works for me.
After reinstalling Windows 10, I do have problems. Trying to figure out why it worked and does not work anymore :-(
bummer! I have not used it with windows 10 yet. If I get to try it I will update my post.
Thx for the feedback
