It's a weird Top Trumps set, but here goes my audio list:
Cart Machines (Sonifex)
Dolby A in a 3U rackmount which you had to lug from area to area because we could only afford one*, and worked in a room with but never had to use SR
Technics SLP1200B which in its ASC modified version (fader start) was without doubt the 'Rolls Royce' of CD players at the time
Whatever those skookum Gram decks were that the Beeb put into nice wooden cabinets with rotary fader start - EMT, I think
Studer B67 (the little one)
Revox PR99 (the plastic one)
Done tape edits with a razor blade and sticky tape.
Nagra T and Sony APR5000 timecode lockable 1/4" machines
Otari MTR99 24 track
Sony PCM-7030(?) DAT machine with timecode lock
Sony CDP-something CD player
A brief dalliance with the AMS AudioFile, which we won't talk about
...and I didn't even work in Sound - so don't get me started on video and film...
"Do notte buye Betamacks"
Professionals never listen to advice, so the world used Beta formats (Beta SP, DigiBeta, SX, HDCAM, HDCAM SR) until the death of tape, and there are still HDCAM SR and DigiBeta machines at work for archive use.
Oh, and I have a laser disc at work with the Sony BVH-2000 maintenance course on it, but no means of playing it.
*Dolby A was almost always required when transferring record company promo videos, which arrived on "G-Spools" - tiny plastic 1" VT spools with about 6 minutes of tape on them. They were so light that you had to put a weighted flange onto the machine with it, or the machine would either sulk or tear the tape into little tiny shreds trying to sort its tensions out.
