It was an Amstrad, and it came with a
(This was about the size and weight of two reams of heavy A4 paper short edge to short edge, 8MHz 8086-clone CPU, 640k RAM, twin 3.5" 720k floppies, small black and white LCD screen with no back light making it Somewhat Difficult to read unless you had a good light source behind you, and CGA graphics = 80x25 characters or 320x200 in four ugly colours, or 640x200 in black and white. Eight or ten D size batteries would run it for about an hour when disconnected from the mains.)
Doing it this way was, for a while, the cheapest way to get a 2400 modem! Some people bought one, attached their 'real' PC to the PPC's serial port and ran a small program on the PPC so their PC would think it was directly connected to the modem.
They cost about £800 new. I paid about £250 for a second hand one, less than a year after the launch.
