Prototype 128D with 3.5 inch Drive



    image





I have disassembled the unit to clean and photograph it's components.


Let's start with the power supply.

Not sure what to make of the date.
Year is 85, that clear, but the 031 is
not so clear. There is only 52 weeks
in a year, so no need for three digits
in the number.

Here is Commodore's serial number
for this unit. The 31'st week of the
year is in August, so maybe the 031
is the week. I'll talk more about what
I think the origin of the unit is a little later.

The bottom of the lower case half. The case is a standard European plastic 128D. These cases hold the keyboard in the bottom half.

The serial on the case bottom, and a name; "KENTRON". Did Commodore name their early samples?


image



Inside of the lower half of the case.

I have to wonder what Commodore
was thinking. Handles, a place for
the keyboard, and something to wrap cords around on a desktop computer. Where does one attach the monitor?

These plates level out the bottom of the case, on the inside.

Ready for the motherboard
and power supply.
