I have been having a lot of fun with Graham's Emulator. I believe that it is close to brilliant. The Emulator 28 pin pod simply plugs straight into your 6805P3 circuit and you drive the device via a PC serial port. I needed a single chip micro for a special project and feel the 6805 could be the answer. I just hope that it's cost effective in the long run.
Prices seem to vary dramatically at the moment.
Well at least, they are available at retail outlets. They have no stock of my immediate needs, and don't seem very interested in selling anything. I had trouble buying a P3 manual. I had to push my case a little before service was forthcoming. I thought there was a recession.
