Can you post one or two pictures of the ET4000 please?
I'd like to look at the traces to the OLB connector in detail.
If it is just one (or 2 or 3) slot it is very likely NOT EISA. Next hint would be the sticker on the BIOS chip, then the chipset itself.
I could have a look later, but I know full well it's not EISA:
- it has "Local bus" printed on the PCB
- it works in a motherboard with a single "UMC Local Bus" slot, which is identical to OPTi Local Bus
(I wasn't 100% sure of the latter, but I know this card is an OPTi Local Bus card and it works without smoke & flames in the ULB slot)

that card is 110% SPECIAL SNOWFLAKE - it only works in that exact slot, on that exact board.
Not that extreme, there were quite a few boards with OPTi local bus. This is the only one I know with UMC local bus though.
Now the ECS Local Bus, that's more of a snowflake. Only used on one or two boards, 100% physically identical to VLB, but most definitely not electrically. I found that out the hard way. Magic smoke was emitted 🙁

Got, for free, 124 ram sticks:

- 72p (37)

How do I test 30p? Does 72p work with Memtest?
Memtest works with x86 CPUs. If you have a version of memtest that will run on a board wth 30p SIMM slots, it can test it.
It is better to memtest with one stick at a time or just go all sockets?
Elimination.
Test with the largest number you can at the same time (8x 30p SIMM was fairly common at one point).
- If that passes, they're all good. Proceed to next batch.
- If it fails, test with half the SIMMs. Pass? They're good, the error is in the other lot.
- If that fails, you're down to four (=1 bank with 32b CPU); swap out two with the known-good SIMMs. Pass? They're good, one of the other two are bad.
- If that fails, swap one of the two remaining originals with known good. Pass? It was the other one...
- Fail? You found the dead one.
Always re-test the other half just in case, you may have more than one dead SIMM.
