HP 9000/743i & 744 VME Workstation
4.10 HP 9000/743i & 744 VME Workstation
4.10.1 Overview
The Anole 743i and 744 workstations are VME Single Board Computers (SBCs). The whole system
processing unit (SPU) together with the memory and several I/O controllers sit on a single-height 2U
VME board, which needs to be installed in a fitting VME cage. This cage provides power and an
VME bus connection for routing of I/O to either other VME boards (VME devices) or the so-called P2
connector.
The 743i and 744 SBCs feature a small set of expansion cards, which plug into the available expansion
slots and include GSC-mezzanine (GSC-M) and PCI-mezzanine (PMC) cards. It is also possible to use
an EISA or PCI cage on several of HP’s own systems based on the 743i and 744. Since the board also
features an VME controller it can talk to and control other VME cards on the same VME bus/cage. Of
note is that some of the pins on the P2-VME connector on the rear are used to route GSC bus traffic to
several of the expansion options. VME cages need to be properly jumpered to support this in order to
not interfere with these transfers. Also, it is dangerous to use these boards in a VXI cage since some of
the VXI pins carry voltage which would result in damaged devices on the GSC bus.
The 743i is technically based on the design of the HP 9000/715 workstations, the 744 partially on the
B132L/B160L workstations.
The 743i boards are used in the 748i industrial workstations, the 744 boards in the 745 and 748
industrial workstations.
4.10.2 Internals
CPU
743i/64: PA-7100LC 64MHz with 1KB on-chip I L1 and 256KB off-chip unified I/D L1 cache
743i/100: PA-7100LC 100MHz with 1KB on-chip I L1 and 256KB off-chip unified I/D L1 cache
744/132L: PA-7300LC 132MHz with 64/64KB on-chip I/D L1 cache
744/165L: PA-7300LC 165MHz with 64/64KB on-chip I/D L1 and 512KB off-chip unified I/D
L2 cache
The 1KB on-chip L1 cache on systems with a PA-7100LC is not really a true cache.
