I am losing my mind and missing something stupidly obvious?
I'm trying to get a 486 VLB build going. Everything goes fine, except I can't get a damn serial mouse working.
- Tried two different ATX power supplies (with an AT converter), and measured all voltages fine in both cases including -12V (one gives only -11.25, but the other gives -11.90 and same problem)
- Tried two different Socket3 VLB motherboards (QDI 486VP3 and Soyo-025K)
- Tried with a DX25 and a DX33, with both 25 and 33 bus speeds
- Tried VLB WS 0 and 1
- Tried 3 different VLB IO + 1 ISA controllers
- Tried 2 different known working Logitech mice
- AMIBIOS "summary" table during boot shows Serial: 3F8
Cutemouse 1.9 gives me:
Installed at COM1 (03F8h/IRQ4) in Mouse Systems mode
...and the mouse doesn't work. Also tried to change the jumpers on the IO cards for other COM ports, other base addresses and IRQ, etc..
Logitech 6.00 and 6.50 say the mouse is not responding. Microsoft Mouse says no mouse found. Sigma, similarly to Cutemouse, says it initiated mouse on COM1/3F8 but it still doesn't work.
I have other VLB builds working with a Logitech serial mouse, as and never had that issue before, at this point it feels like I've swapped every possible element and thoroughly tested everything 1 by 1 and can't make any sense of it.
I'm all out of ideas and need to take a break. Please help my sanity 😀 cheers
