Good for you Happyrat1.........
Amazingly, I still sometimes use my very small AC/DC 1990 Yamaha PSS 680 which was ground breaking for that time, and some of the programmable voices/styles/manual drumpads can even be effective now.
The 680 has a 5 octave mini keyboard, 32 sampled drum sounds, a set of drum pads below the keyboard with 3 fill pads, a sync/intro/outro pad and start/stop pad. There is also a pitch bend wheel and a MIDI Thru port in addition to the MIDI In and MIDI Out ports with 16 midi channels. Stereo built in speakers and 2 x jack output plus aux in.
The synthesizer section can play up to 12 voices at once, which also translates into 12 part multi-timbral plus drums. It has 5 memories for your own custom synthesized sounds, 5 recordable tracks for song sequences and 5 memories for chord progressions. There are 100 pre-set voices, 100 drum track styles, multi digital effects, portamento, arpeggiator and a synthesizer editing section, keyboard tuning, transpose and some MIDI function buttons. At that time, many of these functions could only be found on ToL very expensive synthesizers.
At 77cm x 30cm and weighing 3.7k you can tuck this mini powerhouse under your arm and take it off to the beach - a happy very portable board!
