Greg Holmes and his Fairlight studio, mid 1980s.
All of this equipment (except for amp rack, speakers, and TV) could be, and often was, relocated to recording studios on a moments notice. Not portable, but at least transportable!
Left to right: 1/2" 8-track reel-to-reel, 1/4" 4-track reel-to-reel, amp rack on wheels (with phono and pro VCR on top, and cassette tape, tuner, surround room simulator, power amps), Fairlight CMI Series II CPU, Fairlight keyboards and monitor, amber PC-compatible monitor and keyboard, road-case rack unit (top to bottom: Korg MS-10 mono analog synth, MIDI routers [Roland MPU-103/104/105], Roland SDE2500 digital delay, Yamaha REV 7 digital reverb, Dynafex D-2B noise reduction unit, rack-mount PC-compatible XT computer behind grey faceplate, Yamaha TX 816 FM tone generator [equivalent to eight DX-7 sound modules], two Ashly SC-50 peak limiter compressors, patchbay), A-frame keyboard stand (top row: Roland SBX-80 Sync Box, Roland TR-707 drum machine, middle row: Yamaha DX-7 direct from Japan, bottom row: Tascam M-216 16-channel mixer, MP180 8-channel mixer). On the shelf in the background are Bose speakers and a large JVC TV/video monitor.
Note the light grey flight cases for the Fairlight under the desk and keyboard stand.
