|I have now made a card cage to hold the boards and motherboard. This is how it looks :|
The PPMC set takes advantage of the IEEE-1284 hardware signalling protocol, allowing multiple register addresses to be selected and transfers accomplished with minimum CPU overhead, and maximum data transfer rate. This requires a parallel port that can operate in the ECP or EPP mode. It is possible to use any bi-directional parallel port at the cost of additional CPU overhead. Note: You MUST use a cable marked "IEEE-1284 compliant" for this system to work reliably.
Also, if using a PCIe parallel port card, it has been discovered that Startech, SIIG and Rosewill cards with the OXPCIe952 chip will not work. (PCI (not express) cards from SIIG have worked fine for years.) The Saba PCIe card with the NetMos 9900 chip has been verified to work.
An alternative system, for stepper motors only, is the Universal Stepper Controller.
