My last turbo button switched my 80286 IBM PC-AT clone between 8 and 6 MHz, not always without crashing.
6 Mhz would have been the IBM PC-AT reference speed, but I never bought anything "original": far too expensive!
I'd say there was no "usual" because that used to be IBM's way of doing things.
Which never included anything as simple as a turbo buttons to my knowledge.
On their mainframes it's instead a vast sliding scale, with very painful expenses for every bit of MIPS you'd have to buy on-demand. The hardware usually came with quite a bit of extra capacity and then they'd only charge you for the regular capacity you needed.
Until you needed more and then they'd extract all the cost of over-provisioning as well as an IBM premium, painful enough to give life to PCs.
It was clones for me, right from an Apple ][ clone start.
I still have original IBM PS/2 keyboards, but those I didn't buy: I fished them out of recycling bins and they are the true Steinways of keyboards with an orignal asking price of around $2000.
I still ache at the thought of how many were discarded without rescue, it's like tons of Stradivaris that could have been saved.
Well actually I buy Lenovo original notebooks these days. But aren't Lenovos more like IBM clones, too?
