Default Re: ICE Speedmaster 1000 Eprom programmer

Still waiting for the step down transformer ...so in the meantime I retrofitted this VIC20 pcb with bases on all the chips even the 555 timer.
You can see just how bulky the replacement rom/eproms are needing special pin convertors for 27c64 eproms.
Yes these work just fine but I wanted to fit pin compatible eproms which dont need the conversion bases.
Hence my interest in the programmer..
