HP 86

The 86 was an even more modular 80 Series machine than the 83. The 86 had no built in printer, mass storage or display. The 86A came standard with two interfaces for 9130 floppy drives and a parallel (Centronics type) printer interface. The 86 had an output port for composite video. It was commonly connected to the 82912A (9 inch) or 82913A (12 inch) monitor. The 86A came standard with 64K RAM. The 86B replaced the 86A in 1983. The 86B ommitted the two disc drive interfaces and parallel printer interface in favor of a single HP-IB interface. The 86B also came standard with 128K RAM, and had built in Electronic DISC ROM.
