About the PET-PCG-2024 PCB
PET-PCG-2024 is an open source PCB design by cbmuser, published on GitHub. It is a 2-layer board measuring 53.9 × 136.3 mm, with 15 components from 13 distinct parts.
Other key parts include the 74LS257, CHARROM SOCKET, IDT7130, CHARROM and 7400. By type, the board carries 6 ICs, 3 connectors, 3 resistors, 2 capacitors and 1 jumper.
From the project
All to the successor of the HAL PCG 6500
It's also possible to rebuild the original hardware: https://github.com/InsaneDruid/PCG-6500 for the early BASIC1-machines. There you'll find also other usefull stuff for your PET.
My version fits into the newer dynamic PET-board (CBM 2001/3001) and uses DMA-access at $a000 or $9000 for transfering the chars. There is no CB2-sound, I want to combine this in the future with a joystick-adapter at the userport. You can use a IDT7130 in DIP or PLCC52. You only need one of them ! The actual hardware is not tested in all cases (on/off function). Basically it works and new software is under…
