My mistake was quickly browsing the Digikey catalog and seeing the PICmaster WITH Pro-mateII for $3400 or so. I see that Digi has the emulator alone for $2500, which I can beat down through the distributor, and also in light of the fact that there were no other comments on the question, I see that my mind is pretty much made up. Just an aside to you, I have a nagging problem that I should have an answer to by tomorow, but it has hounded me for a long time. You previously answered the vague question months ago with 'must be the code'. When I start an A/D conversion on a 73A, and I am still in an int routine while the A/D finishes and thus the interrupt doesn't get serviced right away, I get +-2 bits of noise on my A/D result. As soon as I cut other chunks of code out, it goes back to rock steady readings. My problem has been that I can't just cut the code out and run. I have a real juggling nightmare of interrupts, and can't do that. Tech in Arizona has no answer to the problem, and I presume it is an undocumented eratta. I am awful close to the answer and will get back to you. Christopher Eddy, PE Pioneer Microsystems, Inc. Pgh, PA
