KElly, I honestly don't know if you could tap the 6809's crystal taps; I bet you can, IF you use a cmos buffer… nice idea, if it workes… heh heh. Upload the EPROM? Ech! That means I'll have to connect the eprom programmer to the system…. hmmmm… Or, it means I'll have to type in the code and assemble it in here, which is kind of a waste of time. On the other hand, if I connect the programmer to the system, then I'll have to write an interface program for it…. which would NOT be a waste of time. On the other hand, I don't _have_ any time! <grin> I would MUCH rather send you one – is that alright with you? Hope so. The new circuit does NOT use the same type of input circuit… that is, it uses all 8 data lines and the PC flag (whatever they called it on the parallel port, I dunno right off) as well as (of course) lot's of grounds. I wouldn't use 4066's, I think – no drive capability. We are currently planning to make the thing a pass-thru device; it uses the parallel port to get data into the system, and it uses an audio channel to get it back out again (transmit AFSK). There will be a button (10-pole switch) that makes the thing a pass thru, then you can just plug your regular stuff into the rear of it. I'll look at the EPROM. Thanks again! BY the way – I have the interface here; I think it may be done. Works outragously on black and white sstv and fax…. working on color now. –Ben–
