I think I saw this on a catalog but I can't remember which product was it. Is there such thing as an ISA card where I can mount a socket 7 pentium processor and RAM so that it will override the 386s processor and ram. Use the processor and ram from the card instead of the processor and ram it has on the motherboard, don't wanna throw it away before I find out if I can still give it some use.
yes, i saw that too. it was on the same site that was selling swamp land in florida for real cheap. i believe the brooklin bridge was also up for sale.

If you want Pentium performance, it probably makes more sense to buy a Pentium motherboard and put in your 386 case. Here's a site for upgrading PC's: http://www.sopot.net/pc/index.htm

To the guy from the first response, why dont you do something usefull with your life and stop wasting peoples time.

I think the guy was trying to tell you that it's not a good buy.
At this point, putting any noney into such an old machine is not going to be cost effective. You might consider replacing the motherboard with new, but frankly I would replace the entire system.

There were upgrade chips that could turn
your 386 into a 486.They can still be found
from time to time on EBAY.

That's complete and utter bullsh!t - you can't use an expansion card to upgrade a 386 to a Pentium.
-ISA cards run at WAYYYY below the bus speed of any Pentium.
-ISA cards can address only 16 megs of memory (24 bits). Pentiums need to address 64 bits.
-ISA cards have, what, less than 100 pins? Socket 7 has 321. How are they going to deal with that? All 321 pins need to be directly linked with the motherboard's bus.Upgrading a 386 mobo to a Pentium can be done, provided that it will fit, and 386s can be upgraded to 486s somewhat easily.

Just FYI,
There were overdrive chips that would change your 486 (to clarify: 486 not 386) into a pentium (I think the fastest they went were Pentium 100 Mhz). They were made by a company named Evergreen (although I am sure other companies manufactured them too). Perhaps that's what you were thinking of? Also there were expansions cards were you could add memory to your system in case the built in slots were full. I have never heard of a CPU chip on a expansion card that you are referring to, but that does not mean it wasn't done. I am sick and tired of people posting "something can't be done", only to see in the very next post that indeed it can be, and has been, done. Some people need to think before they post with their negative comments.

Back in the days of 386 and 486 computers Promise Technology had a hard drive controller card that could take up to 16 Megabytes of memory. I do not think it replaced the processor but acted as a hard drive cache that took the load off the CPU. However these controllers had an on board
CPU. The CPU was not a pentium and is the closest thing I remember to what you describe.

you actually can get an isa card with a pentium chip on it, and it does plug into a ISA slot on a 486 or 386, ill have to scan the article - it had onboard ram and serial connections and just used the devices on the isa bus since they are all connected together -
