The Apollo Domain 10000 from Apollo Computer were marketed as
personal supercomputer geared for complex workstation applications like electronic design automation (EDA) and mechanical computer-aided design and engineering (MCAD/MCAE).
The Domain 10000 were designed and sold by Apollo Computer, a technical computing market leader in the 1980s, based on their own PRISM RISC architecture, before HP bought Apollo and integrated it into the HP 9000 lineup.
Apollo Computer was bought by HP at the end of the 1980s, taking over their product lineup with a plan on integrating technical computers (HP 9000 and Apollo) and software ecosystem. The Apollo workstation series was carried on for a few years under HP/Apollo branding; HP integrated Apollo as their workstation business unit with Apollo co-branding on the HP 9000 RISC workstations for a while but Apollo products and technology were phased out soon after and HP concentrated on its own PA-RISC computers and architecture.
Even though the DN10000 and PRISM were soon phased out in HP’s product lineup post-deal, HP was still officially communicating an upgraded PRISM processor and Apollo hardware in 1989.
HP envisaged double the computing power (from 22 to 44 MIPS), increased caches to 512/512 KB, increased memory to 512 MB using 4 Mb DRAMs and up to 18 GB of SCSI storage and called this the
DN10000TX upgrade in 1991 – which apparently never shipped.

The Domain 10000 is based on the Apollo PRISM architecture, centered around a system backplane with central and expension slots. Processors, memory and high-performance graphics are attached to the central X-bus. A central service processor (MC68020) also attaches to the X-bus and controls the VME and ISA I/O buses for devices and peripherals.
- CPUs 1-4 attach to X-bus
- Memory 1-3 attach to X-bus
- FDDI networking attaches to X-bus
- Graphics engine attaches to X-bus
- Service processor attaches to X-bus
- X-bus, processor/memory bus – system backplane with 160 MB/s data rate
- VME main bus for I/O – for disk and network controllers
- ISA (
PC/AT) bus for I/O – graphics and peripherals
- ESDI for storage I/O, SCSI was an option
- Apollo proprietary memory boards that plug into X-bus slots, each taking two slots
- Up to three memory boards with each up to four 64 MB daughter boards
- 16 MB minimum, 128 MB maximum with parity, (704/720 MB theoretically)
- Eight X-bus slots (shared with processor and memory boards)
- 40-plane graphics option for 3D drawing, using one slot (1280x1024)
- 80-plane graphics option for 3D drawing, using two slots (1280x1024)
- FDDI dual attach
- 68020, 12 MHz on Utility board
- Communications controller with 2 X.25 and SNA ports
- Four ISA slots (
- IBM Token Ring card
- Simple 8-plane graphics if configured as workstation (1024x800)
- QIC tape controller: Western Digital WD7000
- Six or five VME slots (depending on VME extension)
- Ethernet card (13837)
- Apollo Token Ring card
- ESDI drive controller: Interphase V/ESDI 4201
- SCSI drive controller (X-ADD-TFC)
- 80286 on ETH802.3_VME
- Up to six networking cards are supported, two of each type
- Up to four disk drives in the system, options:
- 360 MB disk drives: Micropolis 1558 and Maxtor XT-4380E
- 760 MB disk drives: Maxtor XT-8760E
- 1/4" tape drives: Archive 5945C
- Up to two disks on each ESDI controller
- SCSI drives apparently possible in Domain OS SR10.4 with WD7000-ASC
- I/O depends on installed configuration
- 3 RS-232 serial
The only operating system for the Apollo DN10000 servers was Domain/OS, Apollo's own operating system from the 1980s, originally called AEGIS and later rebranded. DN10000s used a special version of it, and were only supported by release SR10 which allowed users a selection of environments to run on top of Domain OS – AEGIS and Unix (BSD or System V). There were no other operating systems available to speak of.
Performance of a single-CPU DN10000 was roughly equivalent to a DECstation 5000/200 and slightly better than a Sun SPARCstation 1+.
