My last desktop machine had an ASUS Pentium-3 (no ISA slots), USB1
only. It has outlived the original hard drive, CDROM, and power supply,
but I think it makes more sense these days to throw these systems out
rather than "future-proof" them, especially if a fanless SoC could be
less power-hungry and noisy. It seems to me that people who want to
get more life out 10yr old hardware need to be part of some sort of
trimmed down "LegacyBSD" project that caters to their special needs.
You all know more than I do about the orgs that are following the
stable-6 or stable-7 branches, but are they using ancient CDROMS with a
limited life span?

mcd and scd are ISA-only devices ... They were important for the

on x86, I'm guessing there aren't too many 486 SX/DX machines
running 8.x.
486 were the last for which ISA was the primary bus, but ISA was
still present (bridged from PCI) on most Pentium systems and common
at least as recently as Pentium-II. (I don't have a disassembled
P-III handy to check whether it has an ISA slot.)
Most Pentium II and newer systems had IDE connectors on the motherboard. Many
of the Pentium I ones did too. Only if you didn't have IDE connectors on mobo
would you be likely to consider one of these CD's. Also, I think they topped
out at 4x or 8x speed since they had a custom interface.
