Adding a vintage ISA bus slot to a modern computer #VintageComputing #Retrocomputing @rasteri

Andy on Twitter and YouTube has demonstrated the dISAppointment board. It’s a 16 bit ISA slot (which were in old computers from the PC inception to the 1990s). How can a fairly modern computer be interfaced with an ISA card?

In 1996 the Low Pin Count (LPC) bus was formed to interface slow peripherals to PC processors. This is through a chip typically referred to as the PC Southbridge (where ISA circuitry still exists). While the LPC is not usually available on a connector to interface to, it can easily be accessed by using a socket added for a trusted platform module (TPM), which many desktop motherboards of recent vintage have.

In the video below, Andy demonstrates using an ISA sound card in Doom on an i5 motherboard, amazing.
