Historical Documentation for Sun Sparc Hardware

• FOSS Open Hardware Documentation
• Manual for Force CPU-8VT describes a sun4m like machine
• Good Manuals for the Sparcbook 3gx a SparcStation 5 clone (grab 3gx.pdf)

I/O Programming

All early SparcStations used the Z8530 serial chip as well as the Ultra 1. Ultra 5 and 10 use the SAB82532.

As qemu emulates mostly early SparcStations at this point it may be best to start there.

Serial chips specific documentation

• Scanned Zilog 8530 Technical Manual (15Mb pdf)
• Newer Z8530 PDF ~1.3MB

Note that on SparcStations, the Z8530 is controlled through a an Sbus to Ebus bridge via the slave I/O controller and is not programmed directly refer to the system manuals. EBus is a slow 8 bit peripheral bus.

The Slavio chip controls serial, nvram, TOD clock etc.

• Slave IO Documentation

The Macio chip controls Onboard Ethernet, SCSI , and

• Macio Documentatino

Note/TODO

WANTED: "NCR SBus I/O Chipset Data Manual" as it should provide more complete documetation of these Macio/Slavio chips

The System technical manuals often include some detailed information about programming the perpherials the Force computer and 3gx manuals look to be good references.

QEMU by default emualtes a sparcstation 5 so a system almost exactly like the sparcbook 3 with the exception of the graphics card being different TCX or GX Note that QEMU only emulates the TCX graphics adapter at the moment. The 8bit GX adapter is probably the most common on real hardware however with several variations some with more video memory.
