3 Descriptions of Systems

The basic building block for all the 7000 and 10000 systems is a single system cabinet called

the Laser Platform. Most 7000s consist only of this cabinet, although an expander cabinet

can be added. 10000s use the same system cabinet along with 1 or 2 expander cabinets and

1 or 2 battery cabinets. The basic Laser Platform is described ﬁrst.

3.1 Laser Platform

3.1.1 Logic

Refer to Figure 1, Laser Platform BLock Diagram .

The basic system interconnect is called the Laser System bus or LSB. This runs on a 9 slot,

double sided backplane. On the LSB sit CPUs, Memories and the I/O port (IOP). Each CPU

and each memory consists of 1 module and therefore takes up 1 slot. The IOP is also 1

module. The minimum conﬁguration is 1 CPU, 1 memory and 1 IOP. The remaining 6 slots

can contain CPUs, up to a maximum of 6, or memories, up to a maximum of 7.

The IOP has 4 ports (aka. hoses) and each can connect to an XMI or Futurebus+. At present

this can be up to 4 XMIs or up to 3 Futurebuses and 1 XMI. (1 XMI is currently required

for booting). For a description of Futurebus+ see Section 5.

The IOP to XMI interface consists of a single XMI module known as a LAMB. Another slot

in the XMI is taken up by a CLOCK module. This leaves 12 slots for I/O adapters.

The IOP to Futurebus+ interface is a single module known as a FLAG. This occupies 1 slot

in the Futurebus+, leaving 9 for I/O adapters. (LAMB and FLAG? - Sounds like they were

dreamt up in the local pub!)
