The 7936 and 7937 were the next generation of HP system discs to replace the "washtub" discs of the 793X range. The 7936 had a capacity of 371 MB and the 7937 had a capacity of 571 MB. Seek time was 20ms with a burst transfer rate of 2.35 MB/s. The initial models (7936H and 7937H) came with an HP-IB interface. The 7936XP and 7937XP offered an addition 2 MB cache. The subsequent 7937F offered a fibre optic interface.
The 7936/37 used the CS/80 command set.
Given their size and age, these discs are still surprisingly reliable. As of 2013, six of the ten units at the museum were functional.^ TOP
