Hi Ben, I should have the currently released interface done tomorrow (if not tonight). Now if you could be so kind as to upload the eprom contents to your data library, I could burn the eprom and give it the smoke test – then hook it up to the printer port and try it out. Sounds like your new circuit will use the same input circuit as the current interface, so I may just share that part of the circuit. Could probably get the 4 Mhz clock from the 6809 if that doesn't load down the oscillator circuitry in the 6809 too much. I will figure out what all I have to order for parts when you finalized the design and released it. Do you think the interfaces would work alright if they had to talk through a CD4066 to get to the Amiga's parallel port? If I use a few of them, I should be able to put all three interfaces in one box and have a selector switch to determine which gets to talk to the Amiga. (Plus route the audio as necessary) Regarding the eprom's data lines – it is where the lines come off the bus and go to the D0-D2 pins of the eprom that they get reversed. You have to look pretty close and trace them out. This wire wrapping isn't going too bad (so far). It's a shame the sockets are so expensive. 73, Kelly
