Connection wise it has a headphone/line out socket, a microphone socket and the external power input socket.
The PMC100 has 100 instrument or "melody" voices, and another 15 "melody and accompaniment" voices.
The keyboard is a membrane similar to the EDP Wasp.
Its based on the Yamaha FM sound chip, was launched in 1986, it had a nine-channel FM synth with a 100 presets, a membrane keyboard, 8k of ram, a built in cassette recorder, and buttons for a strap. It was designed in part by British PC music pioneer Lyndsay Williams, who designed the first ever PC soundcard, for an Olivetti in 1987
I was personally involved in the design and marketing of this product when it was first produced and actually made the mock-up model that was the basis of the layout and design of it. I also co-wrote the user guide at the last minute after the guy who was originally commissioned to do it came up with a load of crap!
Although it may seem pretty basic now, it was extremely innovative at the time and gave rise to similar 'music notebook' type products from Yamaha. The great advantage that the Yamaha products had of course was MIDI which I fought hard to be included on this product but Philips didn't want to pay the extra!"

"1984 - 1985 Vintage Sequential Circuits SIX TRAK synthesizer Model: Prophet 610 in the original box... This 4 octave keyboard comes equipped with midi in and out and when linked to a drum tack machine, combines the multi-timbred ensemble with a programmable rhythm section. Each sequencer (A or B holding six separate traks) allows for an 800 note memory allocation per sequence, and this memory storage can be increased to 4000 notes when combined with a model 64 sequencer. Of course, with midi, the playing field is wide open to many possibilities that go beyond the two I have mentioned. The back panel also includes audio out which can also be used for a head phone jack or a speaker output, and a footswitch controller jack is also present. The foot switch is not provided, but is an inexpensive purchase that can be obtained through any music store. This fun machine also includes a pitch and modulation wheel, polyphonic and unison mode functionality, programmable track speed and volume, track erase, memory – full warning, legato function, voice stacking, a flexible arpeggiator and 100 ready –to-play factory programs."
