Man... I think I got hosed on this one.

Why don't you just take the CPUs out and actually see what you have there?

I'm guessing you missed the part about the heatsinks being adhered to the processors? Why would I make a whole post with photos asking about this if they were easy to take off? 😋

I tried prying in every reasonable way possible without damaging the board, including using a heat gun to soften the adhesive and they do not budge. They are also blocking the levers on the sockets, so if the coolers don't come off I would have to yank them straight out of the locked sockets, which is really a bad idea.

Rather than destroy what is probably a (to me) useless pair of boards and old Pentiums, it makes far more sense to just be able to return them to the seller as-is if they don't match the description. Once I checked the thickness of the ceramic I realized that it was easy to tell they were definitely not K6 processors.

Sorry, I didn't understand that not being able to remove the heatsinks would prevent the removal from the socket as well.

FINALLY a working 286 Octek board with PLCC socket and no acid damage.

Nice, that one looks familiar, like I had one pass through some years ago, be nice if it turns up. Got a suspicion it was the one I left behind in a move that had a 25mhz Harris on though.

"The card was not PCI-E"

I read it with the Stanley Parable voice.

Great score.

What could be the difference between this and the one on the retroweb with the U2 PAL populated?

Heh, yeah, I keep picking up laptops that only need $200 worth of parts to make them worth $100 in great shape. One thing that can work for getting life out of them, is clipping battery voltage from an adjustable supply directly to battery +/- contacts in the battery bay with batt removed.

Not sure what you mean about the 760EL power plug, this is what I am seeing that it needs...

With 16V on it.

Unless you mean the plug into the adapter, which looks like it's going to be a standard "kettle cord" like is used on desktops.

Well most of these laptops needs more work than just battery like some screen replacements, repairs some cosmetics like cracks one tosh has a 40mb drive but it goes to power on and turns off loop so hdd is to to replace. About ibms noo they are using this type of plug 4 pin hexagonal. Anyway i will work on em after finishing current retropc's haul building win95 machine on s7 second on 486 win.3.11 dos and second 486. But Currently i'm wiring a board of 386 from cash terminal with amd 40mhz(have that board from 2 years).

Looking at some of the chips, one board is almost a year older. Could be that stuff was optimized so that one of three PALs could be left out? You could backup them with a programmer, the contents are very hard to come by.

Could be cost optimised too, one year it was considered "workstation"y enough that they thought it better do some protected mode stuff super correctly for Xenix, then next year it's looking like low end budget that ppl only want for DOS and Wordperfect so cut stuff to save a buck.
