    I'm building myself a 6502-based single-board computer, with the aim of
running it off a 4.8V NiMH or NiCad battery pack. But I've got a problem. I
need a programming language for it. Aparrently there were many BASIC
interpreters sold for the Synertek SYM-1 (aka SY-VIM-1), MOS KIM-1 and
Rockwell AIM-65. Anyone know what happened to the companies that produced
these? Ideally I'd like the source code for a 6502 BASIC interpreter, but
binary code would be OK too. The SBC will communicate via a small LCD panel,
RS232 (so I can hook it up to a "dumb terminal") and will have a hexadecimal
keypad and an optional hard drive, too. Anyone care to make any suggestions
(or submit some code)?

BTW, I also need some info on the Intel 8271 disk controller - I've got two
of these little devils and Intel's datasheet makes absolutely no sense at
all. I've also got a Western Digital WD1770-PH 00-02 that I might be able to
use instead. First of all, which is the better controller? The 8271 or the
1770? Also, is it possible to overclock a 1770 or an 8271 like you can a
I'd love some schematics and/or some source code. I really don't fancy
disassembling Acorn's 8271 DFS and Watford Electronics' 1770 DFS...
