Genius G540 eprom programmer
« on: November 29, 2010, 11:50:04 AM »
Its cheap, its crappy, it doesnt do everything it claims to do but it does kinda work.
Ive used this to dump and burn a few eproms, program GALs and program a PIC16.
Programming the PIC presented with a problem but I found a way around it, everything else seemed to work ok. The software is written in the finest chinglish but is fairly easy to use.
It claims to be able to test IC's and RAM. It cannot test RAM and the IC test is poor at best.
Got a new all singing all dancing programmer coming tomorrow as a part ex for my Dataman S4 and this isnt needed anymore.

Be wary of AMD 27c128 chips, some need 21V on the programming pin, so you will need to use the power supply for the burner. Also be very careful that you check the voltage that the programmer is going to use matches the chip. Hopefully it will say what it is set to in its GUI, compare this with the chip as the markings on AMD chips tend to be a bit random on the 64 and 128 chips. You can select the exact chip and the programmer will give it 21V when the chip actually wants 11.75 - result is dead eprom. There seemed to be 2 variants in the AMD line, both with the same chip ID but with a killer voltage difference.
