Don't know, but I have a "Precision 466i" (I think 486DX-66), and another "Dimension 466" (I think 386+387) boxes sat in the corner which were offloaded to me in the past for something aparently useful that I did back when... Will check what their 'vital statistics' later or tomorrow. I was told the 386+387 was a 386+387, however it might not be.

Dell marketing iirc, went something like this:

Precision (CAD variant)
XPS (Performance variant?)
Dimension (not quite XPS, but apparently substantial enough to be called something else)

I've wondered what this "466" model number represents every time a spot them in the corner. o.0
Any info would be appreciated.

I have a Dell Dimension XPS 466DV, and I believe this is what it means:

D: "DX" CPU
V: VLB motherboard (mine)
4: 80486 class CPU
66: 66MHz, or possibly the motherboard can handle up to a 66MHz CPU.

OMG, that site you linked is awesome. May be just a diagram, but i've never seen a 486 poweredge. You've made a dell fanboy very happy.

Also now I know I can upgrade to a DX4 as well 😀

I'd love to see pics of that 466i. Btw, that's spot on marketing-wise. I'm wondering if they pulled any badge tricks like later models. I've got an xps M1710, or was it a precision M90, or an inspiron 9200, LMAO. I do know i'm getting a number nine GXE with the XPS, but it looks like the soundblaster is missing.

Was taking a look at some of the systems on that archive site and spotted something interesting. The OptiPlex 4xx/MXe has what looks like an ATX PSU connector. Not sure if it actually is ATX (or if it even supports soft-off for that matter), but it sure looks like a 20 pin ATX connector. That would be a first for a 486.

Sure...

Dell 466i precision & 466i dimension.

It was the first time I opened them, and was greeted by these thingys...

CT1740 & CT1810

Can't see the "466i" models listed 🙁. Both machines had 486DX66 CPU (despite the dimension having an SX33 labelled heatsink?) so your assumption is probably correct.

Apart from the ram and expansion cards present, machines look identical, have same mobo's/risers, same PSU... pretty much everything the same. Lots of dates of 1993 and 1994 dotted around on components so I would place the 466i after 94, but before 96 since I cannot find reference on the '96 Dell website? Or am I going blind o.0

Yeah, the 4xx means 486, and the x66 means 66 MHz, but i'm not sure what the "i" is for.

Does this look like your board? It was listed under "4xx/P, 4xxs/P, V4xx/i, V4xxs/i - NP"

Thanks, yes layout looks about the same.

Apologies should have taken some more piccys of the internals. Will do when I get the chance.

If so, I noticed some neat VRAM sockets there you might wanna check out. I should be getting my XPS tomorrow. I'll post pics when it arrives.

I want to explore this more.

I have a Dell OptiPlex 466 Le (DX2-66) and noticed that ATX-style PSU right away. The power switch is a soft switch, not like the traditional hard toggle switches we know AT-style PSUs require.

Is it proprietary? This is the first time I've seen a soft switch on a 486 PC.

Can you upload pics?

I'm really enjoying the spike in 486 OEM system photos which has emerged on Vogons as of late. Does yours have a PS/2 mouse port?

I would have loved a standards-built 486, but I couldn't turn down a fully functioning OEM machine. Yes, it does have a PS/2 port. I'll have to take pictures when I get home (and remember to, 🤣).

In the mean time, it looks something like this (Googled for images):
