Some mothernoard and hard drive questions with pics

Hello folks! I have been tearing into a few older computers and IBM desktops that i recently obtained and have a few questions. Thanks for any help or advice!

Probably a stupid question for some, but after opening a few up, I cannot find a generic looking cpu.



I got all excited when I saw 486 on this cpu, but it is soldered on and does not appear to have "gold legs". Would this board pay differently then other motherboards?



These look to be some pretty big hard drives. They seem to be in most of the older IBM's I have.

Thank you both. I think I try to open one of those hd's up for the fun of it. Nice tutorial Mechanic 688!

That drive marked ST-225 mite be a fun and easy one to open up. That thing is an old MFM 20 Mb Seagate. MFM was one of the standards before IDE came out. It only has 2 platters in it and they are probably orange.

if you do ebay you might find better than scrap on those boards and drives there

I'll check into it, thanks Bear. How about the cpu in the first pic? All i see is a bunch of long cards that you can see going from left to right in the pic. They look like long video cards. Thats what the majority of these boards seem to have on them.

In the first picture I am guess it is a real old computer and the CPU you are looking for is small like this
Pull out the main board and post a picture of that.

I belive picture 2 is another motherboard he has questions about.
Yes it is posible it there is processor on one of the cards. The main board does not look like any backplane I have seen. Looks more like an old XT/AT board.

sometimes you can tell from the outside connector if it's a video card or other, if it has outer connectors. Sometimes you can google numbers of the boards for info. Sometimes it's an extensive search process

The 486 cpu needs to stay on the board or you will hurt the value. There are 2 good size socketed ic chips you can pull off it though.

Sometimes on those old boards the metal around the keyboard connector will be gold plated. If it is i always remove them.
