The Personal TBC I is a single channel, infinite window time base corrector which plugs into an ISA slot. It doesn't require active ISA slots (eg via a Bridgeboard) as it only uses them for power. The card supports daisy chaining up to four TBCs and a vector scope wave monitor so that all units can be controlled via the serial connection. The card has a BNC Video Out connector, BNC Video In, VNC Timing Out, BNC Timing In and a phone jack style serial connector. The card was usually supplied with software simply called TBC with V4.0 being the latest. An external remote controller, and an external enclosure were also available for this TBC. This card is probably NTSC only.
ID (1-4): Sets the unique ID if multiple cards are daisy chained.
