Sticking a 100MHz 486 OverDrive in the LGR Woodgrain PC

Unboxing and upgrading (er, sidegrading?) the Woodgrain 486 with an actual 486 processor again. No more Pentium. This CPU is the venerable DX4-100, new old stock!

LGR-viewing veterans will know my Steve1989MREInfo references go back a ways 😁

The one thing i do NOT miss from those days is configuring jumpers

It’s like Clint read my mind. He said accessory packet and I immediately thought of Steve… nice.

I remember getting a Pentium 63Mhz Overdrive Processor for my IBM PS/2, upgrading from a 486/66. It actually didn't work initially, we fortunately lived near a Microcenter and one of the associates informed us that we needed a new bios for the new cpu to work. $10 and 1 new eprom later and I was rocking Command And Conquer Red Alert like it was my job. How I miss the good old days.

If I remember correctly, the Pentium overdrive was the same basic performance as a 486 dx4 100 (as seen here) but it included the additional instruction set of the Pentium. So if for some reason, software really required a Pentium cpu to work, that was your solution. A lot of people bought the Pentium over drive thinking it was better than the 486 and it was not.

I keep imaging duke nukeem saying "overdrive" whenever this boots up.

"Don't see any coffee instant type 2" .... nice.

[SparksNZeros]

lets get this out onto a motherboard..nice.

Clint! teach me things from my past that we couldn't afford as geek kids!

A LOOOONG time ago, I had a 486-DX50 that I could overclock to 66MHz on an older VL-BUS mobo. I had to physically replace the oscillator to do so. So front side, processor bus AND cache ran AT 66MHz. It smoked my DX4-120 in most CAD and math operations. It's amazing how, back in the day, FSB was KING! I had CAD customers who insisted on using PentiumPro 233MHz even after the PII-400's came out. The PII's used 66MHz cache bus, whereas the PPro's used native FSB for the cache clock. They really slayed!

Shame no coffee instant type 2. Steve would be disappointed 😔

[dvdemon]

I will always fondly remember the very first time I fired up Quake and watched in awe the dark goodness of the Necropolis demo in all its glory on my 166MHz Cyrix system back in 1998 after unpacking 17 pirated ARJ-compressed diskettes.

Aaah, good times!

I think the fault lies with the ISA bus speed or the Chipset used, Shelby from Tech Tangents ran into a similar issue with the same 486 chip.

[dreammfyre]

I bought one of these as a 13-year old, over optimistic kid and then proceeded to try to install it in the wrong socket, bending the outside pins. Lucky for me the store owner was good sports about it and was able to bend them back and gave me a full refund.

I know this is Blerbs but your skill of filming CRTs never ceases to amaze me. It's beautiful and truly appreciated.

[psychorabbitt]

4:11 that MRE reference was pretty... nice.

[peterg.]

I love that LGR’s MRE is an Intel Overdrive!

[shards-of-glass-man]

It feels so weird to see a new and sealed 486 box, my brain has started to see the processors of that era as archeological artefacts for some reason

[Kawa-oneechan]

I love how that SCSISelect™ line just straight-up lifts the curtain on how they did the graphical logos.
