Which works out just fine for the 2716s being the smallest part my programmer
can handle. :-)

I guess that could be expected.

Forth is definitely one of the other things that I'm looking at, but it's
style is rather putting me off. I have a 68HC11-based board that comes up in
it, and should probably hook it up and play with it one of these days, or
get an emulator going, or something, just to try and get a handle on it.
If you know of any online resources for that language I'd sure like to hear
about them. I did snag two of Leo Brodie's books, for starters, but not a
whole lot else.
