Real computers ~~have~~ require wheels...

Removable Drives

CD ROM Drive. CD clips onto spin motor just like a laptop CD drive.

Note the 2.8 Mb floppy drive

Provided Digial Unix CDs

Boards

Board Cage Closed

and Opened. Here is where the CPU and RAM boards live.

Top side

and bottom of my EV5 CPU board

CPU board. Possibly an EV4

Memory board. Machine supports one or two. This one appears to be soldered.

Memory board. This one has 32 simms of 16 Megabytes each for 512 Mb

Drives

Random photo of SBB caddy

Label under an SBB caddy Note the unbroken warranty label :)

Front

Where the caddy connects to the drive inside. This shows a 68 pin drive, but other caddies have a 50 pin interface internally

Caddy connector to back plane

Inside of caddy

An external SBB rack.

Inside case, where the drive caddies connect to the SCSI backplane. Note the extra connector and cable for the second SCSI controller.

I am continually amazed at the levels to which trademe users both rise and sink. A trademe user contacted me and offered this drive backplane for nothing. It has three 2Gb drives and three 1Gb drives. I'm going to add this item to the auction.

Front and

Rear.

The sucessful bidder could simply keep it as spares, or with a bit of thought could connect this to the qlogic SCSI controller and have some more drives. You would need to connect the SCSI bus and the power connector, and probably a very good idea to protect the rear of the unit too.

Other

Small display on front. I think its so you can identify different nodes if you have more than one (expensive stickey label!) and so that a user can see the POST testing before the monitor starts. See below for a recording of that (30 Mb)

Keyboard/serial/parallel connectors.

View down into the machine.

Standard generic PCI NIC demonstrates that the PCI is standard, and the linux driver Just Worked.

PSU was Made In Austria

NCR SCSI host adapter. This optional second SCSI controller allows the drives to be connected to two hosts, accelerating disk/host transfers by decreasing bus contention. (buzzword city there!)

Specifications

This is the hardware:

CPU: 64 bit Alpha 21064 EV5 at 291 MHz returning 1162 bogoMIPs (one CPU), SPECweb96 rating of 570 (one CPU)
RAM: 512 Mb in 32 x 16 Mb 72 pin simms
SCSI: two on-board NCR controllers based on the NCR53C810 chipset. Work perfectly with ncr53c8xx module.
HDD: 7x2 Gb and one 1Gb SCSI drive, a variety of DEC RZ26, RZ28, DSP3210S, RZ28B
CDROM: DEC RRD43 SCSI cdrom drive - a "laptop" format with the lens in the tray.
Tape: DEC TLZ07 SCSI tape drive. Never used it at all.
FDD: 2.8 Mb drive. Never used it at all.
Weight: 25-30 kilograms estimated.

Not Working Yet

These are the niggles I haven't fixed yet... Always work in progress

Strange dmesg errors I periodically get this error message
```
XXX Todo
```
The message seems to appear more often when the machine is under load, but has never caused any problems that I've noticed.

Audio

This is a server and has no audio hardware. However one could add an ISA, EISA or PCI sound card like any normal linux box.

USB

USB does not exist on this machine.

This machine does not run X itself, however I run various X applications like xterm and xload to a remote machine.

Other Interesting Stuff

Windows NT ?

I heard this unit can run Microsoft Windows NT? You heard correctly. However the various Unix options and the Windows option are mutually exclusive, and depend on totally different boot loader.

Display

That wee green display shows a user-programmable string while machine is running. It is most useful at boot time because it displays all sorts of stuff about the POST tests. Here's a recording of the machine booting.

29 Mb MPG

The first message is from elsewhere in the boot process.
