The switches I'm using for feeding multiple Ethernets to Raspberry Pi are Zyxel GS1200 series. Their manuals should be available online to look how they are used.
The other inexpensive switches are pretty similar. Most of them are using chips like the ks8995 from Micrel. There is a pretty good description of the works in the datasheet. The switch devices do not always use all the features of the chips, however.
My 89441A is fine, it's my external 10Base-T adapter that failed, hence the MAU transceiver (AT-210TS) replacement.
Ah. We generally ignore the built-in Ethernet and use Prologix GPIB-Ethernet adapters. We commonly use them with several instruments at once.

I often like to have the VSA control panel on the PC display so prefer to have a real LAN interface to run the X server. The ethernet to GPIB adapters are certainly useful for my other HP kit of that era.
Interesting--I didn't know it could do that. Once I get the PSU fixed I'll have to try it out.

It's alive and well in the industrial world, sadly. The low speed isn't the issue, it's the old garbage computers (embedded ones) that work at those speeds that's the issue. Been working on monitoring/automation with some modbus over ethernet devices, and I'm really having a hard time grasping just how obsolete and insecure this stuff must be.
That while pipeline hack was probably way easier than they hammed it up to be.
Industrial automation machines are expensive pieces of hardware, expected to function for many years, sometimes decennia. The choice to use common of the shelf computers and software to control them is a bad choice, because those computers are garbage even before they hit the market. They're *intended* to be garbage right from the start.

Hah! Turns out sane people are not extinct after all...

SFAIK, all 100Baset and copper GBit PHY interfaces still work with
10Baset.The actual rate is negotiated.
You mean the Pico? A reg'lar RasPi has .... 100Baset? GB? already.
It should be fine but try it first with your kit. IMO, the cheap switches are more likely to work - just plug those into the rest of the network.
Optical can be quite cheap and much more reliable.
