In resurrecting abandoned projects

Or, where the heck have you been?

Once I began analyzing some of the routines internal to PROMAL ages ago, I found myself fascinated and then obsessed with the simple elegance that the system is written with.  I’ve been working on commenting a full disassembly of the program but haven’t yet decided to officially relase it.

Therein comes a challenge for myself.  I’d like to document the steps I used to reverse the language’s concepts, internal variables, and machine code here.  However it will take some effort to refresh my memory as the initial disassembly was performed nearly two years ago, and I’m a bit stuck for time.

Let’s just provide a screenie of the title page for entertainment purposes, as well as a shout-out to the venerable COMPUTE! Books series that covered many CBM systems including drives and computers.

Hopefully life will be a bit more generous with spare time and inspiration so I can complete the work as well as get some serious documentation about the process posted here.

By the way, that font was HARD to find.  Still not an exact match for the one COMPUTE! used, but it’s close enough to pass. 🙂

[Edit: Found an attempted escape : q and removed it.  Meh.]
