Changing the terminator to improve impedance matching for the Virtual 2315 Cartridge Facility

IMPEDANCE FOR SIGNALS IS COMPLICATED IBM engineers the 1130 for 92 ohm impedance on cables, although in practice there are ribbon cables, traces on printed circuits, wire wrap on the backplane, and twisted pair wiring involved in the path between the 1130 and its internal disk drive. However, since the engineering goal was matching 92 ohm impedance, I will use that as a working start. The 2310…
