I have the above subject P1 board. It has VGA output connector, RCA out, PS2 mouse and keyboard. Headphone jack. Additionally a small breadboard area. A header to access P0-P7, VDO, VSS, 5V. Barreljack for 6-9 volts (must have that powered to code it)
I fail to find documentation for it on the old Parallax website. Any leads are appreciated.
Thanks.

On the bottom you should find the Parallax SKU for that board. Use that to search on the old Parallax web site for documentation.
There are no numbers on the bottom (underside). Only an oval sticker "QC PASSED". What else would help?
Nothing official, but here are some links that might help...

The part number for this board is 32100. I still have not found any other info. This says datasheet but it's just a catalog. https://datasheet.octopart.com/32100-Parallax-datasheet-60137.pdf
Edit: schematic at the end of this document: https://datasheet.octopart.com/32300-Parallax-datasheet-13538341.pdf
Gold! Thank you!
Also Gold. Thank you!
I've attached a zip package containing the schematic and Test Code files for the 32100 board.
Appreciated!
I looked at the 32K EEPROM, it doesn't look like I can upgrade it. The 64K EEPROM of the QuickStart board (as an example) doesn't seem to match the solder pads of this Demo board.
If anyone is interested, I made a MIDI shield for the Demo board.
yes please! Schematics and details?
3.3v (220 Ω) to red dot, GND to Green dot, Pin 6 (220 Ω) to Purple dot. Top 2 not used.
(I just happen to use pin 6, pins 0-7 work equally well)
Understand this is MIDI out only. MIDI in by convention protects the circuit with an optocoupler.
I am using Tachyon FORTH to send byte info to a MIDI device.
BAUD for MIDI is 31250.
Most of the soldering in the picture is for stability, not for electrical connections.
Some circuits may not have the resistor on the data line. I have chosen to include it.
