Heathkit H-11

S/N 1286/01

The Heathkit H-11 has a LSI-11 bus (Q-Bus) based PDP 11/03 16 bit CPU board manufactured by Digital Equipment Corporation. The entire chassis was manufactured by Heathkit. The backplane is a little unusual because the boards are installed with the components facing downward. Heathkit was later acquired by Zenith. After the acquisition, H19s became available with Zenith's branding as the Z19 in 1979. The Heathkit H27 RX01 compatible dual floppy drive has a switch on it and special software so it can format RX01 diskettes.
