The EPROM may be for an extension BIOS, which is useful for adding netboot or large disk support. PALs could be anything.

That was my assumption, but what kind I don't know. SMC probably didn't specify and it was up to the user. The PALs I think were for address decoding for the EPROM.

All my ancient stuff is long gone ancient history by now (multiple cross country moves tends to do that), but the early networking cards did bring up some good memories of my teen years in the 90s when I had gotten my hands on some surplus ARCnet twisted pair cards, and proceeded to wire up the house for networking...not because I needed to, just because I could...or so I thought :-DD Turned out that using regular ol' telephone wire didn't work out all that well... :-//
I got pretty dang good at hiding cabling though, so that Dad wouldn't figure out that I was drilling holes all over the house to run this stuff through the basement. It wasn't until they sold the house years later, long after I moved out on my own, and they sold the house that I got a call from Dad - "You know anything about all this telephone wire in the house all over the basement, but not connected to the other phone lines???"
"Maaaaaaybeeee" :-DD

Hi,
My contribution is a pair of ISA cards from a product called a "386Gold" from a company called "Logicraft" which you can read about here;
https://en.wikipedia.org/wiki/Logicraft
Not shown in the photos is a 286-NEAT chipset based motherboard with a number of 8 and 16 bit ISA slots. The first card I've photo'd enables the motherboard to talk to an Ethernet port, floppy disk and a proprietary Status Display. I have a floppy disk containing an operating system and (what looks like) all the software to enable the system to boot.
The second photo shows one of four 386 based PC's on a card which (I think) all run MS-DOS.
If you have a DEC PDP-11 (or maybe other later DEC machines) with appropriate software, the 386Gold system will allow terminal users to run MS-DOS applications (like text mode spreadsheets) on the 386 cards as if they were connected directly to the terminal.

I don't remember now. It might have just been off the internet. But I do have VGA capture devices that I use from time to time.
