Default Re: Early EPROM programmer.

The softy 2 has an in circuit emulation option to be the EPROM to test it. - that is rare today I think as it is so quick to flash a new test - the flash even configures the FPGA hardware! I think I posted before that this EPROM simulation was a function that Sandy White used to create Ant Attack for the Spectrum.

It seem the 8080 code I wrote blind has allowed Ian to get the Triton programmer - it has a board connected to the 8255 PIO that supplies the programming voltage and a timing monostable so is a half way house system to burn 2708's.
