Hi,
I've got a SparcStation Voyager. It's currently running Linux. Sadly,
Linux does not have a driver for the STP4020 Sbus<->PCMCIA bridge, AKA
Nell. Happily, NetBSD does have a driver. The solution, you're probably
thinking, is obviously to run NetBSD on it. However, for the project I'm
using this machine for, I already have a bit of Linux custom kernel code
written so I'm hesitant to migrate and have to rewrite it. I thought I'd
give a whack at porting the NetBSD Nell driver to Linux.
Surprise, surprise, it is turning out to be harder than I originally
thought, largely because I can't find the chip datasheet. There is a link
to it on Sun's web site, but the link is broken. I found references to it
in old Sunsite mirrors, but couldn't find the actual file.
Does anyone have a copy of the programmer's guide for this chip? (I found
the pin-level datasheet, but no register-level information...)
It used to live at www.sun.com/microelectronics/datasheet/stp4020 .
Thanks much!
