I see, so it is similar to the trigger system of my DSO. Only that this has a pre-defined TV trigger that detext VSYNC and HSYNC and then counts HSYNC signals. It's also capable to recognize interlace. Still, for me it will be more work to write the little programs and anyways my programming style is very interactive so I had to take my C16 or C116 to the DSO anyway. BTW, shit, I just tested the new 7501 CPU I got as a replacement and it is dead! Really time to construct the 6502 adaptor :-( Only one working CPU left. > It has somewhere around 40 channels, and can record up to 1024 states. > That's enough to watch every interesting signal for a couple of character > lines worth of time.

The first thing I built for my C64 was an IEEE488 interface. Okay, before that I built the kernal replacement for it ;-) Ah, that reminds me of the first printer I had for my C64: A CBM 3022, the worst printer you can imagine! Somewhat similar logic to the MPS802, i.e. only one bitmapped character per line, only that the matrix is only 5x7 instead of 8x8! I actually wrote a basic program to print C64 bitmaps on it and it took about one hour to print. I'm not sure if the printer or the program was the limiting factor. Since the printer was only borrowed I had to give it back after a year or so. But about a week ago I bought one again ;-) What shall I say, it's as bad as I remembered it ;-) So why I'm I telling this story? I got a IEEE488 interface for the C64 with it, pretty well working with BASIC4 and other additional commands, but it uses EXROM and therefore is very incompatible with existing applications. Oh, and it has only German docs. I'd be willing to give it away, for some approporate compensation. The hardware is pretty simple and maybe even crippled, it has only an EPROM, 6821 and what looks like resistor networks on an expansion port card. No proper driver chips. Maybe the most useful thing I got from this deal is the PET to Centronics IEEE cable. Nicolas - This message was sent through the cbm-hackers mailing list.
