ThinkPad Power Series 820

#1 Post by karotlopj » Thu Apr 22, 2021 8:47 pm

Rummaging about in my loft I came across an old IBM ThinkPad Power Series 820 which hasn't been used for 20 years.

Anyone know anything about them?

Yup. It's a PowerPC (RISC) CPU. It runs AIX 4.1 - 4.2.3 or special versions of old Sun Solaris, and NT 3.5.

Also going to point out it has some significant value. I had one about 5 or 6 years ago that worked except for the screen but put out to an external monitor. Regret selling it. Still have the replacement screen I bought.

I found the power supply and switched on but you need to enter a password to do anything. I was hoping to boot from a CD but can't find any way of doing it. Is there any way to reset/unset the password? Maybe there is some sort of keyboard shortcut to break into the BIOS...

Its a bit of an odd beast. Not Windows obviously not even an x86 processor. The Manual is still available I believe in the legacy files here. I will look for it and try to send you a link.

Legacy files at the above address. Looks like some boot floppies.

I found some interesting links:-

And a YouTube video:-

but unless I can unlock the BIOS I have a very heavy brick - it's really chunky for such a small thing,

A fascinating curiosity, and NT3.51PM was interesting with sleep and hibernation way before NT4.0 got it, although contemporary AIX had even better hardware support for the PowerPC portables.

What's the going rate for one of these? It's not even been out of its box for at least five years, perhaps time to send it on to a new home...?
