advice on listing a 'vintage' mb..

model 486 uE-U intel i486 DX proc. I pulled outta a box of boards Ipicked up from a guy that thought he was going to get into "getting the GOLD" out of 'um. I see "some" are selling for $100 'n up at auction. I've researched and not had much luck finding the same exact board. I ran numbers off of the 8 sticks of RAM (??) without finding satisfaction as well.
Any help identifieing them, or advice on if I have something worth more than scrap.

To identify motherboards, usually the chips on it will not help identify. I see a sticker on it in picture 4744, that should yield some info. Also, sometimes the board info is marked into the solder mask. Most of the time however, at least on newer ones, this just identifies the bare board itself, and not the final product.

Also, you would need to test this board before selling...ones that aren't working don't sell for much, if anything.

I wouldn't pretend to know how to hook it up n test it... If it were still in the machine, maybe So the only way to determine what the memory sticks are, would be to check the system info once I have the board hooked up??

Nice pics good quality, good work! I also have a few of identical boards, with the i486 cpu. High grade stuff, keeping them for now.

No, you can still figure out what size the chips are. I agree with JKBINDY, that it's probably a total of 8 MB for all the sticks together. I am not super well informed about these 30 pin sticks, but this is how I have determined them in the past before I had a RAM checking device:

In picture 4747, there are two different chips. I search for those part numbers, and you can usually find the memory size in them. It's usually listed in bits, not bytes. There are 8 bits in one byte. So, megabyte size is 1/8 what is shown.

bp41c1000a-6 size - 1Mx4
4c4001jdj-6 size - 1Mx1

First two chips are 1Mx4 which is one megabit four bits wide. So, 512kilobytes, or 0.5megabytes. Two chips = 1 megabyte.
The third chip works out to 0.125megabytes.

This is where I get confused with my lack of knowledge because the total size doesn't make sense. But it would work out to 1.125MB ram chip.

WoW! thanks fer the math lesson too
