A comment on 80286 ATX mainboard based on the IBM 5170 AT PC. Parent comment
An FPGA is planned for the remaining AT controllers, which are now hard to source:
- the 2x 8237 DMA controller
- the 2x 8259 Interrupt controller
- the 8254 System timer
This will allow anyone to build a modern AT, like this was done for the XT.
