Hi all,
I have just bought a bunch of Chips from a local guy who was going to scrap them.
There are quite a few nice and some rare chips amongst the lot including this Intel A80486DX4100 SK101
I find it interesting that the bottom has no makings at all on it.
Is this usual for later production models of Intel 486 Chips?

If someone could answer my question in the above post that would be great thanks.
This Synertek 6502A Ceramic was also in the lot of Chips I bought and I think it may be quite a rare one as I have only seen these in plastic before.
Have not cleaned these chips up yet but should look much better when they are

All of my late production 486s do not have anything printed on the underside.

By all means, you are most welcome to do so, however I am going to try, carefully, to clean it up some and will then retake some photo's of it.
pm me with your email address and I will send you some photos direct.
Cheers
