First here's a couple pictures of the front of the system.
This is a MicroVAX II in a BA123-A enclosure. Note the TK50 tape drive (95MB) and control panel door.
Here's what the control panel looks like, the lights indicate
system and drive status and the buttons allow me to halt the
system and set the drives as read-only (at the hardware level!)
Here's what the front looks like naked, the BA123-A enclosure
has room for five full height 5.25 inch drives.
Here's what the back of the system looks like,
the only thing of interest is the IO panel door
which opens up. The card near the upper-right
corner is the original Digital service card,
complete with system serial number and the number
of the support center. (Perhaps I should try calling
if I have trouble getting NetBSD up and running?)
Here's whats behind the IO panel door, note the 16 serial
ports. Other things of interest are the power and
Ethernet connectors and the CPU panel which has
the console port with its associated hardware (baud
and operation mode controls) plus an LED which shows
system status during bootup.
The only interesting thing on the left side are the
power connectors and the backside of the front panel.
There are also warning signs that indicate in several
languages that there are numerous things behind the
power supply cover that will kill you, and that you'd
be stupid to open it up.
Expect to see pictures of the inside of the power supply here soon.
The right side is where the interesting stuff lives.
In this picture you can see the drive bays up front
and the IO panel door flopping open. The system's
guts lay behind the center panel.
In this picture I've swung open the center panel
to reveal the system boards and controllers.
Hopefully I'll include more on this later, but this
system has the processor board, two memory boards
(8MB of memory on each), plus various drive, tape
and serial controllers.
