After the initial release of my plans for an IBM PC/XT to C-64 keyboard converter a few weeks ago, I've been sending out schematics and instructions as the requests come in. The requests have just about died off, and now that I have a little feedback from potential users, I'm posting this little addendum. First: The instuction text fails to mention that ESC is mapped to the back arrow key. Second: MANY OF THE NUMEROUS VARIETIES OF 8748/9s REQUIRE PIN 26 TIED TO Vcc (pin 40). In fact, everybody ought to make this change to their schematic. If you happen to have one of the 8748/9s that needs this pin tied high and you haven't done so, your 8748/9 will sit there like a dead duck. :-) Third: Seems that the original code was bug free. Haha. 8748s work fine. (I finally got some to try the code out on). Fourth: At a user's request, I mapped TAB into Ctrl-I. This ought to be helpful for terminal programs. If you'd like the updated program, send me mail. Fifth: Several people have asked about kits for the thing. At this time, I can make everything except a printed circuit board availiable. I don't yet have enough interested people to make making circuit boards worthwhile. If you're interested, send me mail. That's about it. I hope you're all enjoying the circuit. :-) ---Joel Kolstad kolstad@jomby.cs.wisc.edu
