HP 9000/715
Overview
Project names:
- 715/33: Scorpio Junior
- 715/50: Scorpio
- 715/64: Mirage Junior
- 715/75: Scorpio Senior
- 715/80: Mirage

Time of introduction:
715/33, 715/50: 1992
The HP 9000/715 range of computers can be divided into two different series:
- The 715/33, 715/50 and 715/75 were the first 715 series, they feature a PA-7100 processor and are build around an older chipset/mainbus combination. Prices started at time of introduction from $4,995 (715/33) and $11,895 (715/50).
- The 715/64, 715/80, 715/100 and 715/100 are a bit younger and technically identical to the successful 712 workstation.
Internals
CPU
- 715/33: PA-7100 33MHz with 64/64KB off-chip L1 I/D cache
- 715/50: PA-7100 50MHz with 64/64KB off-chip L1 I/D cache
- 715/64: PA-7100LC 64MHz with 1KB on-chip I L1 and 256KB off-chip unified I/D L1 cache
- 715/75: PA-7100 75MHz with 256/256KB off-chip L1 I/D cache
- 715/80: PA-7100LC 80MHz with 1KB on-chip I L1 and 256KB off-chip unified I/D L1 cache
- 715/100: PA-7100LC 100MHz with 1KB on-chip I L1 and 256KB off-chip unified I/D L1 cache
- 715/100XC : PA-7100LC 100MHz with 1KB on-chip I L1 and 1024KB off-chip unified I/D L1 cache
The 1KB on-chip L1 cache is not really a true cache.

Buses
- GSC system level I/O bus
- EISA additional expansion I/O bus
- SCSI-2 single-ended narrow bus
- 715/33, 715/50, 715/75: VSC memory/CPU bus
- 715/33, 715/50, 715/75: SGC expansion of the mainbus to the SGC expansion card
Memory
- 72-pin ECC SIMMs
- Takes 8-32MB modules
- Eight memory sockets
- 715/33: 6 memory sockets
- 16MB (2×8) minimum, 192MB (6×32) or 256MB (8×32) maximum
Expansion
- 715/33, 715/50, 715/75: One SGC (EISA formfactor) expansion-slot

ROM update
There is a firmware update available for the 715/64, 715/80 and 715/100. This however does not work on a 715/100XC.
- C7X50016.text has details about the contents and installation of the patch.
- C7X50016.frm contains the new firmware.
