HP 9000/705 and HP 9000/710 were the first small PA-RISC workstations, released in 1992. They are simplified versions of the Snakes 720, 730 and 750 workstations in a small case.

The basic HP 9000 technical workstation design was taken over with few changes:

Smaller instruction and data caches on the processor
Lower CPU clock rate
Different memory architecture
Integration of graphics, SCSI, Ethernet subsystem onto a single mainboard
Reduced expansion options
First audio capable Series 700 workstation

HP 9000 705 and 710 were marketed to compete in the early 1990s low-end workstation market. The competition between $5,000 and $10,000 were lower cost Sun Sparcstation IPX and from IBM RS/6000 220 for Unix.

HP 9000 705 were introduced in 1992 for $8,990
HP 9000 710 were introduced in 1992 for $12,490

HP introduced another pizzabox-sized workstation a few years later in 1994 with the HP 9000 712 workstation, based on newer 32-bit PA-7100LC processors.

Chipset

HP ASP chipset, a custom HP RISC design
HP Viper memory and I/O controller, low-cost version implemented in two chips
NCR 53C700 8-bit single-ended SCSI-2
Intel 82596DX 10 Mbit Ethernet controller
Audio 8-bit mono PSB2160 CODEC
Other I/O (serial, parallel, i8042)
HP Stinger (?) CRX graphics, 8-bit

System buses

PBus processor/memory bus, 200 MB/s at 50 MHz (710), 140 MB/s at 35 MHz (705)
VSC main system bus, 100 MB/s at 25 MHz (710), 70 MB/s at 17.5 MHz (705)
GSC system-level I/O bus
SCSI-2 narrow single-ended bus

Memory

HP-proprietary 72-pin SIMMs
Eight sockets
16 MB (4×4) minimum, 64 MB maximum

Memory has to installed in quartets:
first in the even slots (0, 2, 4, 6), then in the odd slots (1, 3, 5, 7):

Benchmarks

System	CPU	SPEC92 int	SPEC92 fp	SPEC95 int	SPEC95 fp
HP 9000 705	PA-7000 35 MHz	21.9	33.0
HP 9000 710	PA-7000 50 MHz	31.6	47.6	0.99	1.44

Comparison to SPEC benchmark data from other contemporary Unix workstations. HP 9000 705 and 710 were slightly slower than a higher-clocked Intel 486DX2 but much faster in floating point, even beating an Intel Pentium.
