Overview
The HP 9000/705 and HP 9000/710 were the first small PA-RISC workstations and miniaturized versions of the Snakes
720, 730 and 750.
The technical architecture was taken over taken over with some significant changes:
- Smaller I/D caches
- Lower CPU clock rate
- Different connection to the memory subsystem
- Integration of graphics, SCSI, Ethernet subsystem onto a single mainboard
- Reduced expansion possibilities
The HP 9000 710 workstation was introduced by HP in 1992 for a list price of $7,490.
Internals

- Memory has to installed in quartets:
first in theeven
slots (0, 2, 4, 6), then in theodd
slots (1, 3, 5, 7):front .~~~~~~~~~~~~~~~~~~~~~~~~~~. | ext. int. ###| | drive drive ###| | ###| | ###| | ###| | 3 x-----x 7 x-----x ###| | 2 x-----x 6 x-----x ###| | 1 x-----x 5 x-----x ###| | 0 x-----x 4 x-----x ###| ~~~~~~~~~~~~~~~~~~~~~~~~~~ back
