I bought this one on ebay (I'm still waiting for it to arrive):

Datasheet:

I'm not very good at Japanese(?), but it seams like it is a 5V
component with TTL compatible outputs. I have drawn a small adapter
PCB that I will try to make this weekend. I'll post pictures of it if
anybody is interested.

Ok, I got the parts and putted the things together. Replaced the
broken integrated oscillator on the RL8A and putted the controller
back in. Managed to load a cartridge and the "READY" illuminated after
the disk spun up! Success!

Now I will try to run the test programs for the controller and the disk.
