How could you forget "Industry Standard Architecture", the bane of my youth?
I once had an old 266 MHz pentium with an ISA network card that was just an absolute nightmare. This was when PCI was dominant and AGP graphics cards had not yet become mainstream, and I guess the ISA drivers just weren't being maintained for Win 98.
I had to go into Control Panel and disable/re-enable the Ethernet adapter about three times an hour, because the connection would simply drop and that was the only rectification that I was savvy enough to attempt.
Right of course! I forgot it since its been so long, but I’ve certainly read about ISA, thought I think it was obsolete by thr time I was working inside computers.
Especially when the headline poses a counterfactual/impossible question they should help as much as possible.
