Have you checked the DESKTHORITY WIKI for pointers

Smallest one I have is this Viglen branded Datacomp DFK2020 which I've used on AT & PS/2 systems

Cherry G80-1800 might be an option.

Not a standard layout but its easy to get used to. I have used one as a work/office keyboard the last ten years and its great to use.

Mine seems to be from 1989 so they are quite durable 😀

Might be an idea to post a pic (or even a drawing) of exactly what you're looking for. By your description almost any mid 1990s rubber dome keyboard (and quite a few mechanicals, like the Datacomp that PC Hoarder Patrol linked to) would be suitable. The fact you're having trouble finding one makes me suspect you might be after something a tad more exotic (96-key layout maybe?).

I can't find a pic of that old keyboard. I may draw one. All I can say is that I think the F keys were round, it had an AT din, and the frame hugged the keys and contoured around the numeric keypad. After conducting more research, I found that a 96% keyboard may suit my purposes, -if- I can find one in beige or white and if it can be connected to a PS/2 port directly or with an adapter. The problem has been finding one that looks old school and not over a hundred dollars.

I'm using one with MX black switches on my main PC currently. Can't complain about it.👍

No idea what keyboard specifically matches the one you describe using back then, but as far as other options for small footprint keyboards go with PS/2 connector ... I'm a big fan of IBM M2 Keyboards. Pretty compact for a full keyboard layout. But not without it's share of issues. Any M2 keyboard you could buy these days will almost certainly need the two capacitors inside replaced. If you don't care about buckling spring, you can grab one of the cheaper rubber dome models by Lexmark (which otherwise physically look the same from the outside). I went through this process with one I bought from eBay and it works perfectly now. But needing to replace capacitors might be more of a headache then you'd be willing to deal with (which I would understand)

I cannot remember the names of any of them, but I also believe there are some Dell keyboards that are beige and also pretty small footprint-wise.

I have a black Dell keyboard that would be perfect, except that it is black and thus fails to match the beige set up. It is a model SK-8115. If I could find compatible keys in beige, I would spray paint the frame.

From what you wrote it sounds like you're more concerned about depth than you are with width. Is that correct?
I had a Sony PCVA-KB1P/UB up until recently that was noticeably narrower than usual, but I didn't measure it, and from pictures I think the depth might still be pretty normal.
It's also gray, not beige. No idea if they made other colors.
If by chance it does appeal to you then they are cheap. When I moved I didn't bother selling mine because they weren't worth more than the cost of shipping.

One of my favorites is the Siig Minitouch. It comes in AT and PS/2. However, the numpad is accessed with the function key. It has white Alps clone switches or blue Alps clone switches (both clicky) depending on the model. It definitely saves space, and is roughly the same as most 60-65% mechanical keyboards.

That looks cool, though unfortunately, it wouldn't fit between the speakers and the edge of the desk. I found an old beige/white KB that is standard yet minimal, and I pulled my desk away from the wall and the 19" monitor is hanging off of the back by about an inch or so.
