Description

The MSX PC is an ISA adapter, developed by Philips. Philips had been developing the adapter for several years, and by 1990 had stopped their MSX activities. The Philips Thuiscomputer Club (Philips Homecomputer Club) in the Netherlands had close connections to Philips and was able to offer the card to their members for 599,- Dutch Guilders.

The ISA card is a MSX2 which you plug into a PC, it comes with MSX2 BASIC, and can be started from MS-DOS through an 'MSX.EXE' executable. With a 'SETMSX.EXE' MS-DOS executable you can also configure to share the host PC disk drives, parallel port and serial port. It also supports using a PC serial mouse for the MSX.

For video there are two options, you either connect a separate TV to the MSX PC adapter, or you could connect the CGA output from the host PC to the MSX PC adapter and connect that to a TV. This would cause both the PC and the MSX video to be displayed on the TV.

The card is reported to have timing issues when used on a PC XT, so a PC AT or better is recommended.
