Timeline for Do AT motherboards (286, 386, 486) really need -5V (besides redirecting it to ISA connectors)?

| Aug 22, 2019 at 15:45 | comment | added | Dan Is Fiddling By Firelight | @J... I've occasionally looked out of curiosity and haven't seen any. Modern chipsets still use the LPC bus](en.wikipedia.org/wiki/Low_Pin_Count) for some odds and ends (eg PS2, BIOS, fan monitors) which should be easy to convert back to a standard 16-bit ISA port, so it doesn't seem like it should be too hard to create a newer generation if needed. | |

| Aug 22, 2019 at 14:50 | comment | added | Dan Is Fiddling By Firelight | @J... the only thing that surprises me is that the number of legacy ISA controlled industrial/medical/scientific/etc machines has finally dwindled low enough that the specialty board makers haven't released a newer ISA slot board since gen 3. | |
| Aug 22, 2019 at 13:21 | comment | added | J... | @mcleod_ideafix -5V was removed from the ATX requirement in 2002 and, indeed, it was only used to service the -5V requirement for the ISA bus. See : Related. The "custom applications" they refer to are mostly niche industrial motherboards (we have some such 2nd and 3rd generation Core i7/i5 systems, for example, on motherboards that also include legacy ISA and PCI slots, if you can believe it.) | |
