Early Compaq turbo speed keyboard combination

[jrmymllr]

Does anyone know if early Compaqs, specifically the Prolinea 3/25, had a keyboard combination that could switch between normal clock speed and a reduced speed? I don't know if this Prolinea allowed this, but I would assume Compaq didn't employ many different methods of this just to keep consistent.

Someone in another forum mentioned they could change the speed with the keyboard, but didn't say how, and won't answer questions about it.

Ctrl Alt + / Ctrl Alt - seemed pretty common on clones BITD - not sure if that applies to Compaqs, but can't hurt to try.

You can try this key combo. There is also a special mode command if using the Compaq MS-DOS that was added to the regular mode command.

That was the first I tried. Of course it didn't work.

Nice! This is the most information I've ever gotten in response to this question and I've posted it elsewhere. I'm thinking perhaps I should be using Compaq DOS instead of MS.

Terribly sorry. I'm not psychic.

Sorry, I didn't mean it that way. I said "Of course it didn't work" because nothing I initially try seems to work.

One small favor: could you just let me know what is on tables 5-3 through 5-6 for the Prolinea 3/25s or 3/25zs, if it has it?

Unfortunately I think the manual I’m using is older that those products.

Here is what I have:

Anyone notice the typo in Table 5-4a?

The "6 MHz 386"? Ha ha that made me stop and doubt myself for a second. But now I see the speeds listed on the tables below that and it's more obvious now.
