arias-mu, pretty much all my retro systems aren't used much. They reside in the closet until I have some idea I want to test out on them.
The VLB SCSI system could easily take an Am486 DX4-120, but I'm intersted in the fastest it can go. I am not using solid state on the VLB SCSI system, just a standard SCSI HDD. I would like to play around with SCSI2SD V6 for use in 386 and 486 systems.
I don't know how, I missed the email telling me of the last 2 replies
It seems like if Vogons sends an email update about a thread, and you don't view the updated thread, then you will not be udpated about the next several replies until you check that thread. So if you manage to miss one update to a thread, then say 5 months go by and someone posts a response, you still won't get an update. The site sort of unsubscribes you until you check the thread again. With the old Vogons website, you'd still get an email after that 5 months saying there was an update. So people, myself included, tend to miss a lot of thread updates this way.
aries-mu: I mention with photos how to modify the MB8433-UUD for 1024K in the PDF manual I provided. I've also produced a jumpered board which lets you select between 256, 512, and 1024K double-banked without needing to solder again. I've been meaning to update the manual again with these photos and the process, but haven't had the time or will power. Working on computers means I loose sleep, which in essence probably shortens my lifespan.
Aries-mu: The manual also mentions how to do 66 MHz. The mod to the VRM may also be in the manual, but it is also located here in more detail: Modifying your motherboard's voltage regulator for overclocking
Aries-mu: Those specific register settings are only for the Cyrix 5x86. They will not work on other CPUs, except for the Cyrix MediaGX. I suggest reading the two links in detail if you are interested: Cyrix 5x86 Register Enhancements Revealed and Register settings for various CPUs
Aries-mU: Yes, the Biostar
Aries-mu: 40 MHz is probably the oscillator on the card. You'll need to look up the Adaptec information for more detail.
Aries-mu: I don't use GoTek floppy emulators. I want the classic feel of suffering thru floppy drives. Also, the bezel colour of the floppy emulator is always off. The white/beige never seems to match.
WOW THANKS so much for the super-thorough info!!!!

Though I fully understand where you're coming from, and I do like your way of looking at it and presenting yourself with a new challenge...the naming of these CPUs was (like has been mentioned before by some Vogoners already) often largely just for marketing reasons. Kinda similar to how Katmai was officially a PIII, but in reality it would have been more fitting to name it a Pemtium II+ and start naming it PIII from the Coppermine core.
The AMD 5x86 was basically just a DX4 unit with 4x multiplier (but with the 16kb cache that only some of their 486 chips had). The Cyrix one is a bit of another story, as is the POD.
In the end I basically ended up accepting a limit of what I could put into the CPU socket and still consider it kinda native to that socket.
What's in a name?

Lol guys! sunaiac that's what always happens eh? And I maybe will keep going back... 386... 286.... 🤣! just kidding.
TETRIUM: wow, your name would be suitable for 486 chips, or maybe those advanced pseudo486 chips named 5x86 or similar...
I see your point, and, if it was merely a mechanical thing, I'd agree totally.
The problem is when emotional aspects come in the way. As a kid using the family 286 for years, and dreaming a 486 for years, as the 486 had been the top PC CPU for years... hoping to get a 386, but dreaming a 486 as forbidden dream.... dreaming and imagining to read that "486" text when turning on the PC, like the boot screen, in the various system info utils, etc..... and then... I got a 486, just a "moderate" DX-33 ISA-only PC, then the kid grew up, the market changed... got a Pentium 60 after a while... things changed... the world changed... everything got so fast..... that "486" text remained in the old memories emotions. So, the dream to have a 486 and assemble it to make it the fastest 486 computer on the planet... and then turning it on and actually READ:
80486
something like that, is unique. It's a feeling. It doesn't care that the AMD 5x86 is the same thing just renamed for marketing. It shows up as a 5x86, not as a 486. In my dreams as a kid the 486 dream got printed deeply, not the 5x86... 😁
So that's the thing....
One thing I'd totally replace, on the contrary, is the mobo: if even a super-modern current mobo (just to say an absurdity) could run the old desired components (486 CPU, FPM 60ns RAM, Diamond S3 or Cirrus Logic or even Ati Mach 32 or 64 SVGAs, etc.), I'd totally go with the super modern mobo. I have no affections whatsoever to any motherboard model or name or code in particular. As long as it had a couple of better than ISA/EISA slots (VLB and/or PCI), better than 30 pin RAM [even 168 pin DIMM ram would be okay (I know, just saying)], pre-SATA drives, and an old-fashioned beige case, it'll be great.
Ah, of course, no HDD. I learned to hate them. Only Solid State Stuff via converters on EIDE/Ultra ATA or even better (even more dreamy as a kid!!!): SCSI UW to some kind of Solid State Stuff!!! Oh man on CACHING CONTROLLER!!!!!
Man, if 486 was a dream, caching controller was a dream made while sleeping in zero gravity in a starship in an alternate universe when I was a kid 🤣
And plenty, PLENTY PLENTY of RAM in which also configure a generous RAMDRIVE!!!!!!! oh man!
I have some stuff, close to this (just no scsi), but it's a DX2 66, still GREAT!
