Fairchild 93C46 serial eprom burn problem
Posted: 14 Nov 2011 16:44
Hi
I have connected a fairchild 93C46 serial eprom to the S4, using the Amtel 93c46 prom support, it reads the data out just fine, but i cannot seem to be able to program the device with a change of data in any location, the s4 just says ram = ?? rom =xx and of course the numbers dont match as it wont program the device.
I stuiply pressed function burn and erase? came up to which i brainlessley pressed ok, the device erased and is now empty (FF), but i cannot load data back into the device! so i now have a blank device with no way of getting data back into it
any ideas as i am stuck and need the data back in the device!!
cheers
