I have several IBM Ps/1 and have upgrade them to the Max with CPU’s and Cache and RAM.
I will say that save your MONEY.
For best value performance just change the jumper to 33mhz bus and install a 486dx-66 in Overdrive socket.
Add 256mb of cache.
The Intel Overdrive 486dx4-100 will only get you about a 10% performance boost over the 486dx2-66Either way the game play performance is not going to change so don’t bother with it.
There is better game play performance in going from a 486dx-50 to a 486dx-66So I would max out with the 486dx-66 and 256mb of cache if you can.
But if you are looking for best DOS game play performance then get a Pentium 100 thru Pentium MMX 233.
I like the Pentium MMX 233.
The Pentium MMX 233 runs like Cadillac and plays most DOS games and apps flawlessly in good performance.
Use a BX440 motherboard and 32mb of EDO ram.That IBM PS/1 is just a collectors item. Not really great at playing DOS games.
Just restore it with what ever hardware will work and leave it at that.
But definitely install the original image software which you can find online.What jumper? thats what we are trying to find , it doesn´t have 33mhz jumper.
What model # does the back label of your IBM PS/1 read ?
Something like 5155Okay, I see from the photos that this motherboard is capable of accepting the Intel 486dx2-66 CPU
And 256kb of cache.
And 16mb of ramThat is what you will needed to get the best value performance out of this computer.
So not to spend too much money on it that really will not improve game performance.Just change the jumper to 33mhz.
for the past 10 post we have been talking about that there is no 33mhz jumper on this motherboard
