Some questions about the 715/50
Here's a few choice entries from the inventory scan on my lovable 715/50:
2. Scorpio Core BA (11) at 0xf082f000, versions 0x7, 0x0, 0x70, 0x0, 0x0
3. Scorpio Core SCSI (10) at 0xf0825000, versions 0x7, 0x0, 0x71, 0x0, 0x0
4. Scorpio Core LAN (802.3) (10) at 0xf0826000, versions 0x7, 0x0, 0x72, 0x0, 00
5. Scorpio Core HIL (10) at 0xf0821000, versions 0x7, 0x0, 0x73, 0x0, 0x0
6. Scorpio Core RS-232 (10) at 0xf0823000, versions 0x7, 0x0, 0x75, 0x0, 0x0
...
9. Scorpio Audio (10) at 0xf1000000, versions 0x7, 0x0, 0x7b, 0x0, 0x0
10. Scorpio EISA BA (11) at 0xfc000000, versions 0x7, 0x0, 0x76, 0x0, 0x0
Scorpio's a 715/old, and has two IO chips in it: WAX and Lasi. Scorpio Jr. (715/33) and Scorpio Sr. (715/75) are identical.
My questions:
a. The docs say that WAX's HIL on a GSC (not GSC+) is at 0xf0201000, but the HIL reported above is clearly in the ASP range. Is there actually a HIL controller on ASP? More importantly, how are the interrupts routed?
b. What on earth is that sound chip at 0xf1000000? Is that Cherry?

uh, no, it has Wax and Asp. Lasi was a later chip. It's very similar to Lasi though.

The HIL controller is definitely on Asp. The interrupt `just worked' when i first stole phil blundell's hil driver he'd written for the hp300.

I actually meant to type ASP, but the letters L-A-S-I came out of my fingers.

So that's interesting... the LASI ERS says nothing about there being a HIL controller, so the HIL controller must have been dropped in the ASP->Lasi transition.
So here's the keyboard and serial situation on older machines:
Model IO Chips Keyboard Serial
==========================================================
712 Gecko Lasi PS/2 on Lasi 1 on Lasi 715/old Scorpio ASP, Wax HIL on ASP 2 on ASP 725 Spectra ASP, Wax HIL on ASP 2 on ASP 715/new Mirage Lasi, Wax HIL on Wax 1 on Lasi, 1 on Wax
I'm not sure how much Wax stuff is actually running for HIL or Serial.
