Siemens PC-X: 1984's 8MHz 80186 UNIX workstation with 1MB RAM
Siemens PC-X (2015)
The Siemens PC-X, an 8MHz 80186-based workstation from 1984, ran SINIX, Siemens' XENIX-based UNIX, with just 1MB RAM and a 10-20MB hard drive. Its non-standard graphics and expansion bus limited its career, but its keyboard survives car runs. The author shares ROM images for MESS emulation and a root-access hack.
You can run over it with your car, it'll still works – like an IBM Type M.
