Notes

Diagram 104B, above, illustrates HP 4Si. This diagram is almost identical to the HP IIISi version (Diagram 104A). The difference is that the pan assembly which houses the formatter board has been improved to accommodate two MIO cards. In addition there is a permanent Centronics parallel interface connector.

Item 9 was revised and slightly improved with some additional high-voltage capacitance in the AC line filtering circuit. All newer NX printers came with the newer part (higher numbered assemblies) and all older printers came with the older assemblies (lower numbered). In applications where the AC power isn't very clean and has switching spikes the newer version may be a bit more fault tolerant. For most people who have clean AC power in their buildings, there will not be any performance difference.
