hello,

ive just won an auction for a standard dual power willem programmer on ebay, it will arrive within a couple of weeks....

the reason ive bought it is to program a new firmware upgrade for a drum machine i own, the manufacturer has sent me the hex32 file and instructions.....

"2 chips 27C512 100ns (any manufacturer) or faster 16bit split mode Hi/Lo byte are required.
The splitting is on even/odd bytes to obtain Hi/Low byte from this intel HEX32 file.
Lo byte comes into the upper socket, Hi byte into the lower socket."

i dont really understand any of this info apart from the eprom type

is this too complex for a beginner to try?

can anyone point me in the direction of the kind of software required (and any help files/walkthroughs) to program these chips using win xp or dos

thanks

It seems the hex data file you got is in 16bit word format. Since each word consist 2 byte data. So, each word has a "hi" byte and a "lo" byte.

You need extract all "Hi" byte from Hex32 and write into a 27C512 EPROM. Also, you need extract all "Lo" byte from Hex32 and write into another 27C512 EPROM.

There are two EPROM socket on the PCB. The "Hi" byte EPROM goes lower one and "Lo" byte EPROM goes to upper socket.

Yes. It is data usage I never see.
