hi has anyone got an eprom burner that can take a 2764 chip? I wish to burn a new Rom image after wiping whats on there. It relates to a an Emu Drumulator which is based on a z80 cpu. I have brought the power rails back online and replaced a CA3086 array which puts the ‘reset’ high to the Z80 to get it going. However, its still not working which leads me to suspect that the either the Rom is corrupted or a 2114 may have failed. If anyone can help it would be much appreciated…
I may have, but no idea where it actually is. I’ll see if I can find it at
the weekend.On 4 March 2015 at 12:26, Raj Patel rajahpatel@googlemail.com wrote:

Thanks Ben. If would be awesome if you had one in your possession
sorted and the eprom was scrambled and my drumulator with Z80 Cpu and CTC is working, or at least the digital part. I’m on to solving the Multiplexing just off the DAC.
Well done!
Glad you got it sorted.On 3 April 2015 at 00:30, Raj Patel rajahpatel@googlemail.com wrote:
