Models

The VAX 10000 was essentially a larger configuration of the VAX 7000. Both shared the same System Cabinet, but the VAX 10000 was configured as standard with one Expander Cabinet housing storage devices, and one Battery Cabinet housing a uninterruptible power supply. These were optional for a VAX 7000 system.

VAX 7000

There were three models of the VAX 7000.

Model 6x0

The Model 6x0, code-named "Laser/Neon", was announced on 7 July 1992 in Zurich, Switzerland with the United States announcement on 15 July. It supported one to four 90.91 MHz (11 ns cycle time) NVAX+

(also known as NVAX++) microprocessors, the value of "x" is 1 to 6.

Model 8x0

The Model 8x0, code-named "Laser/Krypton+", supported one to six 170.9 MHz NV5 microprocessors, the value of "x" is 1 to 6.

VAX 10000

There was one model of the VAX 10000 AXP, the Model 6x0. Code-named "Blazer/Neon", it supported one to four 90.91 MHz (11 ns) NVAX+ microprocessors, the value of "x" is 1 to 4.

CPU module

The initial Model 600 used the KA7AA CPU module, which contained a 90.91 MHz (11 ns cycle time) NVAX+

Memory

The VAX 7000/10000 supported a maximum of 3.5 GB of memory. This was a limitation of the VAX architecture, which had 32-bit addressing.
