Built-in Machine Language Monitor—over 12 commands
So…13 commands then?
Regardless, it’s welcome. For a little tutorial I gave last year I had to write my own sort-of-monitor in BASIC, and that reminded me in no uncertain way that BASIC is a truly terrible programming language. The only reason my subroutines didn’t stomp on my global variables even more often than they did was because I couldn’t remember the line numbers of the subroutines half the time.
I got to play with a Plus/4 (as the C264 became) a few months ago because I have a friend who owns one or two. The design is even nicer in person, and the keyboard is better than the C64, with a couple of exceptions.
First, replacing the RESTORE key with another CONTROL key is a dead loss. If you’re a technical geek, it’s really nice to be able so easily to generate an NMI.
Second, while I approve of moving from two arrow keys to four, not making them real keys (and not using a “T” layout) was not such a good move. It’s kind of a toss-up which is worse.
