I think it must be a derivative of the PC-Jr design. With no disk in the
drives, it boots up into a 40-col screen with IBM PC Jr BASIC Version J1.00
copyright IBM with 42646 bytes free, all white letters on black background.
The initial boot screen is a multi-colour rainbow affair with 64K written at
the bottom left.

The system box has plugs at the back for keyboard, monitor, RS-232, 2
joysticks, printer, audio, cassette and light pen.

My unit has a white 5.25" drive with "360K" written on it in pen - so I
guess this is only a 360K drive, but is probably a replacement as I doubt
IBM would have clashed the colour scheme with the rest of the black system.
