I had two 486dlc one a 40Mhz other either 25 or 33MHz. The 486dlc40
was used for several years as a firewall, only 8MB ram and NetBSD
1.5x through various updates to 1.6x. I think at least one may have
been isa+vesa+pci. That and a 486dx33 firewall ran reliably 24/7 for
periods up to near 200days between the occasional updates.
I still may have some backups with dmesg but chances are there was a
fpu of some kind. From a quick search I can't locate any dmesg but
var/log/messages if anyone is interested:
cpu0: Cyrix 486DLC (486-class)
no indication of cpu speed or features though.
I wasn't able to get either to run reliably on either FreeBSD or
NetBSD 2.0 and up and both the 486dlc systems died in the process.
