If that's a PCB that covers the top side of that
module,
Yes.
Do you have a cable with a white (nylon?) edge connector to fit onto the
front edge of this PCB? If not, you need to make one.
Maybe the odd
cable or connector is missing, but you have the main
parts.
Souns good. When I get the H745 and H7441 PSU bricks working I will try
to build a minimal setup to see if the CPU and RAM is alive. Then add
the peripheral controllers ... Unfortunately SMPSUs are not my friends.=20
Actually, these bricks are relatively friendly in that there are no
lethal voltages in them (they runn form a 20-30V AC input, which comes
from the big transformer and is isolated from the
mains). The maximum
current that will flow in the event of a short circuit is not
that high
either (10's of amps), although it is enough to make small signal
transistors explode (that's from experience!).
And if the machine works there is the next task: Rebuild the rusty RK07.
I bought an RK07 that was full of water (seriously, it poured out of the
hollow baseplate...). After drying it out, cleaning the heads,
connectors, etc, it worked fine...
