Just ordered mine. Probably won't get it on time, but it looks like fun.
Great job Jonathan.

Nothing like getting something done right before the due date, eh? Work has
been crazy and, fortunately or unfortunately, due to a possible coronavirus
exposure we self-quarantined for the last two weeks and I was able to
finally wrap up the user manual and assembly guide for the 2020 VCF East
This year's kit was intended to fit in with the overall 6502 theme of VCF
East 2020; however, I didn't want to do a 6502 SBC since there's a lot of
good ones already available, and I felt like we needed something more
unique. I happened to have some Rockwell R6501Q "single-chip microcomputer"
processors, which are a 6502 core with some changes in a funky "QUIP-64"
package -- if the plastic Motorla 68000 is the "Texas cockroach," this is
the chip package version of a house centipede :)
The R6501Q is 6502 core but adds a few instructions, and has I/O and
control registers in zero page. Stack also lives in zero page. This
provides a little bit of a challenge in porting existing 6502 code. The
EEPROMs included in the parts kit are loaded with the Enhanced Woz monitor,
Steve Wozniak's 6502 monitor from the Apple 1 days. We're working on ports
of EhBASIC and Tiny BASIC as well. They're not done yet -- EhBASIC is going
to be a much larger project, but Tiny BASIC is very nearly done and should
be available for testing this week. Both can be loaded in over the serial
port without reprogramming the EEPROM.
Anyway, check out the Tindie listing for more information, links to source
code, and a link to the PDF manual (which has schematics, of course). We're
going to try and livestream something during Virtual VCF East this weekend.
