Earlier this year I made a Craigslist purchase for what I thought was going to be a 486 Pentium Overdrive 83MHz (PODP5V83). When I finally met the gentleman, what he had was a Pentium Overdrive 120/133 for a Socket 4 (PODP5V133). The asking price was only $15 so I made out much better than I thought. I have never seen one of these and I know they one the more rare Pentium Overdrive CPUs. I have finally gotten around to being able to use that Pentium Overdrive CPU. I got an AST Adventure! Advantage 6060P.

Here are the initial specs:

Pentium 60@66MHz (Overclocked)
8MB (2x4MB) FPM Memory
540MB IDE Hard Drive
4X IDE CDROM
1.44MB 3.5” Floppy Drive
Cirrus Logic CL-GD5434 1MB Video Card (Integrated)
Sound Blaster 16 CT2800 Sound Card
14.4Kbs US Robotics Fax Modem

Here is what I have changed/upgraded:

Pentium Overdrive 133MHz (PODP5V133)
128MB (32MBx4) FPM Memory
Disabled the onboard video and will replaced it with ET4000/W32 2MB PCI Video Card (The onboard video performance was painfully slow in DOS and Windows 3.11)
Removed 14.4Kbs Fax Modem and replaced it with 3Com 3C509B 10Mbs ISA Network Card
The floppy drive was damaged and I had to replace it with another 1.44MB 3.5” Floppy Drive
Swapped the old AT battery for a new one that I made.

The inside of the case was filthy and I spent several hours getting everything cleaned up. I have installed DOS 6.22 and Windows 3.11 and so far everything is running smoothly.
