A recent (2014) and intriguing concept for making a small computer that feels like it was made in the past is the PDP-11/Hack, which only uses a DEC J-11 microprocessor, some RAM, and a common UART.

- rbanffy 2y agoI can't imagine these being cheap - those relics are no longer being made.
- JPLeRouzic 2y agoI bought a DEC J-11 for $45 on eBay, the maximum price I saw was around $100: https://www.ebay.com/itm/326186449818 https://www.ebay.com/itm/326186449818
