Early PA-RISC Systems 825, 835 and 850: NS-1 (NMOS)
Maximum RAM of 112MB (7×16MB), 96MB (6×16MB) with graphics adapter
Seven shared I/O (CIO) and memory slots
Performance of about 9 MIPS
Price of about US $42,500 at time of introduction
Also sold with graphics hardware (825CHX included 2D adapter, 825SRX up to 24-bit 3D graph-
ics)
HP 9000/835 TopGun (also HP 9000/835S):
30MHz NS-1 processor (Not completely clear if the 835 is really based on a NS-1 performance
figures (MIPS) and clock speed (all NS-2 have a maximum of 27.5MHz while the 835 has a CPU
speed of 30MHz) point to a NS-1 while system diagrams point to a NS-2)
128KB cache
4096-entry TLB
CTBs run at 10MHz (their maximum)
Maximum RAM of 112MB (7×16MB), 96MB (6×16MB) with graphics adapter
Seven shared I/O (CIO) and memory slots
Performance of about 14 MIPS
Price of about US $45,000 at time of introduction
Also sold with graphics hardware (835CHX included 2D adapter, 835SRX up to 24-bit 3D graph-
ics)
The 9000/834 was the same as a standard 835 however with a two-user limit
The 9000/835SE is a high-end version with integrated CIO expander
Server version (without graphics) shortly sold as 9000/635SV
A port of early PA-RISC HPBSD ran on 834 and 835, as did an (unreleased) Mach 3.0 port (not
the Mach 4/Lites for 700s workstations) from the University of Utah
A in-progress port of the Chorus operating system (v3.3 nucleus kernel and v3.2 MiX the
operating system personality on top) was ported in 1990-1991 to the 834
HP 9000/850 Cheetah (also HP 9000/850S):
27.5MHz NS-1 processor
128KB cache (combined I/D)
4096-entry TLB
CTBs run at 9.16MHz
CIO I/O bus
Maximum RAM of 128MB with one memory controller (MC0) and 256MB with two memory
controllers (MC0, MC1) [it could be the 256MB/two MCs were only supported on the HP 3000
equivalents]
Performance of about 14 MIPS
