| I love this G-Pascal package. Thank you. Well done.
I have a 2.8"x4.0" G-Pascal compatible PCB design with 64K RAM and optional 28C256 or 39SF010A ROM. A Nano is fitted on-board and provides a 1, 2, 4, or 8 MHz clock, an econo' reset function, and in-circuit ROM programming. If you build the board without the ROM the Nano will load the G-Pascal image into 64K RAM at start-up.
Is there a way to post pictures/drawings here?

| I took this screenshot because I was geeked to see G-Pascal running with an 8-MHz clock and 38400 baud bit-banged serial after replacing the Rockwell CPU and VIA with WDC parts.

Here's another board photo. The only part I haven't found on-the-shelf at distributors is the 'skinny' 64K RAM but they seem plentiful and relatively inexpensive from an AliExpress vendor (5 for $3.36, including shipping to USA).
