I would suggest that it has max fsb of 100 and max multiplier of 8, and they just listed every option that allows for, rather than thinking 800 MHz Katmai was likely.

I seem to remember there are slotkets that have their own voltage jumpers etc - would that be likely to make a 700 or 800Mhz Coppermine work? (Or is BIOS support for the CPU likely to be a barrier?)

Apart from one very very expensive slotket, slotkets that "set voltages" are really just setting 4 VID pins compliant with the VRM 8.4 spec to tell the motherboard which voltage to supply the CPU (overriding what the CPU would otherwise send on its VID pins). If the motherboard doesn't support the voltage requested, the slotket can't do anything about it.

There were a few Slotkets that could do voltage clamping too, IIRC you could feed it 2.0v and it would clamp it to 1.75v which was typical Coppermine core voltage.
Slotkets that can do this are even harder to find than normal ones and are only suited for slot1 motherboards that cant handle voltages below 2.0v which is a lot of the earlier pre coppermine boards.

I have personally only ever seen one that could do this according to its spec sheet, but the seller wanted far too much for it, but I was seriously tempted. Would have made for an interesting reverse engineering project to see if it could be easily replicated or adapted for non clamping Slotkets.

Did not buy this myself, but I still need the world to know:

Someone snatched this Voodoo 4 4500 for 14.90€ (buy it now offer). The seller obviously didn't know what he had, this card usually goes for 300-350€.

Kinda how I got mine 🤣

Had this AT case sent over from the US. Same case I had in ‘91, think this one was put in service in ‘93 based on the chips on the setup inside - VLB motherboard with 486SX. Doesn’t seem to be much battery damage but will tear it down soon to inspect.

Amazed it arrived in good condition though - seller put in two flattened cereal boxes and a torn up clothing catalog as “padding”.

That's a lot of floppy drives...

I noticed this OEM ASUS Socket 423 board. Green is the superior PCB color so if regular ASUS bios can be crossflashed, it's better than the "real" product.
I've already got one from Fujitsu that works but requires recapping and this happened to cost only as much as the new caps.

Picked up a Lian Li PC-70 last night for my growing collection of Lian Li cases (this makes 7 in total - three PC-60 variants, two PC-7 variants, a PC-A05, and the PC-70). I'm very pleased to get this one since it's exactly the same as I bought myself in 2001 after earning a bit of money with a summer job.

And also today a Creative Labs GeForce 256 DDR arrived. Not quite the same as I had when they launched, but close enough. I did find an ELSA Erazor X2 on eBay once but it was sealed in box and silly expensive for something I'd immediately unbox and play games on! Running some benchmarks on this one right now 😀

Will the third floppy be assigned as D: ?

There is one wellknown slotket type that has the necessary onboard VRM parts to produce voltages independant of the motherboard and that is the Powerleap => PL-iP3 (for Coppermine) and PL-iP3/T (for Tualatin).
The early generation (Pentium 2) slot 1 motherboards was designed following Intel's VRM 8.1 guideline and delivered 1.8volt through 3.5volt.

1.8volt is only a slight overvoltage for Coppermine cpu's and a lot of people on this forum have been successful running Coppermine cpu's on early generation motherboards with Coppermine supporting slotkets via voltage jumpers and/or 'auto voltage settings'.
The only aspect that is important when deciding on what type of slotket is required for this sort of project is whether or not the slotket does support Coppermine cpu's.
Older slotkets that do not support Coppermine cpu's need to be modified (which is a relatively simple task)

I am puzzled by the Trident MT600ST with Cyber9385T chipset - with what looks like VGA in as well as out.

I also find that interesting. It feels well build card unlike so many S3 cards from that time. I have no idea how the Cyber9385T performs. And shouldn't Cyber be mobile chip? When I have time, I'll definitely compare this one against S3 cards from that time. I hope it will be fast and compatible 2D card for DOS with good image quality. But that remains to be seen.

Here is some info on the Trident Cyber 9388:

Trident 9388 and DOS games

I have bought this Belinea 14" flat panel from 2001, which allows me to keep my P200@225 setup "period correct" (mobo and CPU from 1999)...

Overall quality is quite good. Could not test the built-in speakers though, I am missing the male-male cable.

At a thrift store I got a Brother MFC-7420 laser printer, thinking it should be a good emergency backup for my DCP-7020. They seem to be essentially the same printer.
Turns out the linux driver is different and broken with the 7420. Guess if I need to swap the printers I'll have to boot Windows to use it.

I need another USB keyboard and a power strip. That should have been easy.
Not in central FL. The stores here seem to hate electronics. They only keep monitors, and kitchenware. One store had printers.
I did buy some DVDs to convert for the file server anyway.

I was about to buy a few mobos. Guy accepted my offer but because it was lower than expected (after 2 years of seeing them around I made one - acceptable), but stated "I won't wrap them nor put any padding, just in a box".
Why?

Got another working Zip100. I'm gonna give it to a friend. Christmas is nigh 😀

I've always wondered if running a virtual machine with an older operating system that tunnels the parallel port for a vintage printer, to share it across the network, is viable. Maybe this is worth trying?

Can Linux work with printers shared from Windows?

Because he likes refunding buyers for damaged parts.

Just brought on EBAY, a Pentium Pro 200Mhz 256KB cache with fan for 75EUR which is the final part needed for my PPro LPX build. Once it working will probably get a Voodoo for it. Also brought a bunch of big box PC games as my birthday/Christmas present to play over the holidays.
Also a new PSVITA screen to fix my one.
Pics when they arrive.

What do you plan on using it for? Do you have a setup where you can still use a dialup modem?

My guess is that it was all broken and he knew it. He also wanted to have shipping paid more than necessary.
A scam. At least it's out of my sight.

I had one of those, at least same shell, and it was surprisingly fast. By that I mean it had MNP5 and ran up to 9600 baud, getting throughput equivalent to some non-optimised, non-compressed or maybe unsupported at diallin head end 14.4 modems. I mean you wouldn't want to use it now you can get 56k which will at least do 33.6 unoptimised, for free or a buck or two. May possibly be okay for some pre 95 modem compatible games though.

I found out about the surprising performance of mine kinda by accident, I was home sick from college with flu and needed to check my college email, the amstrad modem I just had for some reason, "real" modems were $100 or so still, I mean within the "modern" expectations of the time, 14.4 for ordinary ppl 28.8 for biz critical or deep pockets... anyhoo, so I had that, and a "first month free" internet disk, so I hooked it up, dialled in and was kinda wowed that I was getting a kilobit a second, sometimes 1.1 on a lot of text. Which was fast enough to online browse text sites with images turned off (Not very image heavy then anyway, and html code wasn't all that complex either.) It only got one or two "emergency" uses, but I'd had the taste and in coming months managed to score a "white box" 14.4 Zoltrix for $30ish I think it was at a fair.
