Hi!
Below is a proposal for a JoyNet cable for the PC parallel port. I already
built one and it works well.
It can be used for transferring files between PC and MSX, for debugging (PC
logging everything which the MSXes send), by emulators that want to
implement JoyNet functionality etc.
Please tell me if this design is good. If it is generally accepted, it
should be added to the standard.
