Logic Tempo/Datum Turntable query

[Rare Bird]

Hi Susan
Only just noticed this. I'm puzzled by your topic opener as that doesnt look like a Logic 'Tempo'! It is a 'Datum II' arm tho

Indeed early Tempo's had a glass platter. The 2 motor Gemini had a black moulded 1" thick platter and I'm wondering if they also used that on later Tempo's (Tempi?)

What puzzled me Guy, i can't even see the alloy Armboard dish!!. the 'C1' also had that platter aswell as the 'Gemini' but the 'C1' was more like a rega plinth..Looks like the twin motor 'Gemini' to me..

'Tempo' below

If it is a Gemini its a rare beast.

Any chance of more pics of the deck & perhaps one with the platter removed?

what of the 'Gemini' (I think) of susans or the 'Tempo' above of mine Guy?

I had a 'Gemini' last year with 'Datum S' can tell you the 'Gemini' had two airpax motors one at the front, one at the back. the platter has it's sub platter all moulded in one.. simular to the Logic 'C1'...

I was close(ish) to the Gemini as it came about (doing the Voyd at the same time) so am quite familiar with what it involved. There were issues with using those airpax motors and particularly with putting one near to the arc the cartridge travelled through.

The pictured deck has its speed controls over to the left. All the Tempos had controls centre right so I don't think it is a Tempo. I only vaguely remember the C1 but would be surprised if it had electronic speed control.

I'd like to see the plinth & motor(s) under the platter. That platter was a neat thing. I wonder what became of the tooling for it.

Logic were struggling by the time they launched the Gemini (85/86) I don't think they realised the potential of the design fully.
