Bosch Diagnostics / Bosch KTS diagnostic testers
A period ESI[tronic] installation manual says that a PC could use a KTS 500 board and lists free ISA slots among the recommended PC requirements. The board is a PC-hosted diagnostic arrangement, distinct from the complete portable KTS 500 tester.
An owner advertisement describes an ISA-to-PCMCIA carrier for KTS 500 and includes photographs. Treat the exact card and board combination as an observed example, not a universal pinout or a verified release chronology. Collect clear photographs of both sides, part numbers, PC card and diagnostic lead before identifying a unit.
ISA describes the computer expansion bus. No evidence found here establishes that this PC board predates the 1988 KTS 300.
