The ATX64 board is 24,5mm x 24,5mm and fits into an ATX Micro case. The special thing about this new C64 are the 4 card slots, which are an elegant way to upgrade the C64 fast and easy, as well as to create new cards for it yourself. Currently there is a Soundcard with 8 SID sockets and an I/O card with 128 I/O ports. Furthermore the additional cards of the Modular64 fit.
In the rear part of the board is space for pluggable boards for Ports/Interfaces or additional features. So far there are 2 boards (more boards will follow) for the rear part, which can be stacked on top of each other:
- Video/Audio/Serial (internal Pi1541 Zero pluggable)
The following PCB boards will be delivered (only the unpopulated PCBs, without components):
- Video/Audio/Serial board
- Userport/Tapeport board
