Emax

I'm curious, but maybe not THAT curious.  I can't find those chips anywhere either.  It's only an 8 pin DIP though, so I have plenty of those sockets lying around from various projects.  It's only a 16 x 16 bit array... seems like it wouldn't be able to hold too much information.  I guess they are just placeholders for options installed?  I'll check my programmer for support.  I just have one of those universal SIVAVA boards.

You will need to desolder this chip to read in your burner and then you will need to resolder it back onto the main board. I suggest soldering an 8 pin DIP socket in its place and then just inserting the EEPROM into the socket rather than resoldering it direct to the board.

You run the risk of damaging the EEPROM and then your Emax II may no longer recognise the full memory or the stereo sampling. It is also possible you could damage something else on the Emax main board during removal or reinsertion of the chip. Also check whether your EPROM burner actually supports 9306 series EEPROMs, some EPROM burners may not.

I have an EPROM burner so I would be able to produce a bin file for an 8MB machine.  Let me know which one is needed and if there is a risk of this disabling my machine.

If anyone has a 6 or 8 meg machine, and can read the eeprom, send me the .bin file, I have a spare 9306 I can reprogram, to test in my machine. If it works, I'll see if I can get a bunch of eeproms, and program them for 4/6/8 meg machines.
