Vector digital controller
About the Vector digital controller PCB
Vector digital controller is an open source PCB design by emperor-hadrian, published on GitHub. It is a 2-layer board measuring 428 × 293 mm, with 156 components from 12 distinct parts.
By type, the board carries 137 ICs and 19 resistors.
From the project
Design for a DIY computer
The timing will be completely redone: A single normal clock signal, not the stupid "AB Alternating" I made up for the original. The PC will be incremented and a new instruction fetched during any non-flow-control instructions except when the GPRAM is used and the PC is in the same RAM chip (the RAM chips have 15 address lines each) as whatever is being accessed. The bus timing will also be very flexible and will be faster when possible but still slow when the memory is being accessed twice for example. Bus read/write addresses are both now 5 bits. The WRITE/MOVE instruction formats will…
