Just thought I would throw out what I have came up with for the specific "fastest" Intel CPU for each year of 1990-2000 for the spreadsheet. 1990 - 486 DX-33 1991 - 486 DX-50 1992 - 486 DX2-66 1993 - Pentium 66 1994 - Pentium 100 1995 - Pentium 133 1996 - Pentium 200 1997 - Pentium II 300 1998 - …

Which caps are the best for such a task? What about using all tantalum capacitors... overkill/bullshit or feasible?

Spend a good 6 hours finding the source of the LS486E behaving strangely as two unfortunate circumstances happened - a PCI soundblaster and a misplaced jumper on the multiplier pins. When the cache was turned off the graphics and sound card worked, when it was active "extened functionality"(like dma …

Nice looking board! FPM should be fine in any case... seems that it only supports FPM anyways. What size of stick(s) are you using? The sheet you provided does not tell which size "assemblies" are valid... although by having only two slots it shouldn't be that complicated. Use one stick and go from …

Very nice! Abrash was most likely one of the more famous fellas working on this.
Re: Can anyone explain what is TAG RAM?
Posted on 2017-11-11, 21:16
Up until 512K you can get away with a 16Kx8 sram as a tag chip BUT there could be boards that do not accept a chip less than 32K in size(or other than 8K at a speific cache size) as a tag. As stated before, peek into the manual but don't take it as gospel. Why would you take the gamble then? Because …

Really dig the older stuff... the SV2G_4 seems to be a top notch, if not, the top notch board. Any of the cpus you mentioned can be run at 3.45 or 3.6 Volt. I have an AM5x86-133 running at 4 Volt. I'm not aware of a board that just outputs 3V - the HOT433 for example provides 3.3-, 3.45-, 3.6-, 4.0- …
Re: Dudes it is time to make a MOTHERBOARD, i know it wil cost dearly, but i will buy it!

Kits are an awesome venue - just like in the ZX8x days, with the exception that the thing you're building is much more sophisticated. Really cool!

A custom board would be the absolute proof that "love" knows no bounds. I guess a price of up to 1000$ per board could be adequate as the retro-collector is usually an animal of passion. Practicability(snarky spouses aside) and reason would of course cap the price to about 200-450$ though. The real …

Re: dis mobo, 486

So, where would that awful "16bit-ness" occur? Not really sold on the momentum of the 16 bit "slowdown" - more like good ol' marketing blabber. Reminds me of how some magazines tried to paint the PentiumPro in a bad light compared to the older Pentium classic although former was a great performer …

The 486 has lots of potential which overclocking and late era boards can unleash. The Pentium's efficiency can't be denied though and the 486s writing was on the wall as soon as '93. Few days ago I tested a DX60(Overclocked DX50 on a LS486E@60mhz fsb(ram fastest settings/cache one notch below at …

Blood source release would be awesome to finally get a proper release. Maybe Lucius will one day finish his LX variant. Carmack, in more ways than one, did the "right thing", so to speak.
Re: How to detect if cache is real or not?

Well done. Sucks, that not both banks support 32pin chips... although 256KB cache in total is mostly sufficient.

Nice cpu haul! It would be interesting how fast the 85C461 shipset is. I had a board with its successor and performance was pretty good.

Bought some cache and a Riva128 PCI from a local market. Unfortunately the card does not work in the machine it was intended for... the P66. Any idea why it doesn't work? Does it need Pentium 2 and/or MMX maybe? The card has two notches so it should support both voltages... it's old enough. Can't …

At long last, the cache configuration on the SI5PI AIO is complete now - all settings fastest and passed the "required" tests(memtest/Windows/Quake/Doom). Each bank of eight 32K-15ns srams has the same production date as I wasn't able to get 16 "identical" chips though. The tag/dirty ram are 16K- …
