WTT for Socket 7 or socket 5 CPU

[redrumloa]

I have a SBC with no CPU and no manual. It is a socket 7, so I need a socket 7 or possibly a socket 5 based CPU. It is this model.

I have searched high and low, but cannot find a manual online... Anyhow, with a socket 7 or socket 5 CPU, I can probably figure out the jumper settings. So, anyone have one? Besides a k6-2 50 I have to trade, I have various joysticks and some cheaper Amiga custom chips to offer. I'm thinking maybe an Intel 200 might be best, but open to whatever you have.

I should mention passive cooling or with heatsink would help.

The manual says that it will take a k6, so I assume that it may work fine with the k6-2 that you have. I'd give it a try, as long as you can set the proper voltage there is no risk of damage. If you still want an intel 200, PM me - We're not that far away.

Okay, sorry

pentiums-3 (500+ mhz) are all socket 370, they will not fit or work in a socklet 5/7. socket 7 is backwards compatible with socket 5 - the difference is that socket 7 supports core voltage different that io voltage. socket 7 is used for 200+mhz pentium-1 type chips.

You are correct BTW about socket 7 and it being backwards compatible with socket 5. OTOH I am pretty certain Socket 7 is NOT forward compatible with Super 7 (K6-2).

PM sent!:)

A "super-7" CPU like a K6-2 500 can usually be used in a vanilla socket-7 board. There are two potential issues: if the board doesn't support 100MHz bus speed then you can use a lower bus speed with a higher multiplier ie. 83MHz * 6x (the jumper setting for 2x results in a multiplier of 6x for K6-2/3 CPUs) The other matter is voltage: your CPU probably calls for 2.2 or 2.4V and the board might not go lower than 2.8V. In this case the CPU should be fine with good cooling at 2.8V, but the current draw of the CPU may be higher than what the board can handle (touch the heatsinks on voltage regulators near the CPU socket to check...)

Anyway I have a good collection of CPUs here if you still need one.

Yes it does. Mechanically it will fit. However. bus speeds determine the speeds of the cpu. I have a K6-III 550mhz. you need a motherboard capable of 100mhz FSB to use its full potential.
Actually it is one of the best cpus i have had in my computers.
(taking into consideration, time and the os it ran.. Win98se)

I have some old 233 pentiums... both socket 7 and slot 1.
(i still play around with my PIII (tulatin) 1400... )
I think i have some K6-2 as well...
I am going home this summer for some short vacation.
I will try to look trough my old stuff... If i find one of them I'll ship it to you.

If you can get the voltage down to 2.2 V and the power supply is able to deliver up to 11 A, a K6-2/400 will be the best CPU to run. Got one around here somewhere...

Thanks all for replying and for the offers. I now have a Pentium MMX 200, thanks to joekster. Now to give it a spin...
