I just bought one of these fancy gadgets from ebay, and I was wondering what the word on the street is about these things. Are there any incompatibilities concerning the 1kb cache on the TI486 chip? Also, I understand that they are not compatible with the 287 chips, but has anybody tried to use one in combination with a Cyrix FasMath or Intel 287XL coprocessor? I'm really not in the mood to invest in a new math coprocessor.

You could get 4 nice P1 systems for that price.

Yeah, but it wouldn't be the same as running a souped-up '386.

So that part is a 486 chip in a 386 socket?

If you want a fast 386 snag one like I have, 386DX/40 AMD with a 40Mhz coprocessor on a motherboard with 8x30 pin SIMM slots (easy to load up 32MB of RAM) and the motherboard has 256K cache.

It's a hundred dollars though!
That is a lot of money for antiquated stuff that isn't even vintage.:oha:

If it is a production environment with hard- and software that is not compatible with other computer setups than the one they have, and the previous 486 upgrade processor either is broken or is likely to go bad, $100 is not much money to ensure the company can keep running.

Strictly as an 'interesting collectible', $100.00 is quite steep.

I found that Unidec is an electronic repair service, specialized in industrial automation, OEM support and much more. Either they're having a customer that needs the particular CPU or looking to fill the stock just in case a such customer comes in. As I wrote, for a company that relies on a particular old computer to make business or not, $100 is peanut money, probably three hours or less worth of consultants that would re-engineer the computer system to use more common, newer parts.

Edit: On the other hand, a Make-It 286 to 486 upgrade kit was sold on eBay just two weeks ago, final bid $6..
