Main processor(s)- seems the main processOr is made by Texas Instruments but does have Williams Electronics on it. 5410-12862-00
Only other notable processor is Texas Instruments TMS34010FNL-50 Use is still unknown due to lack of Schematics.
The 5410-12862-00 chip was used in other Williams boards and is listed in the T Unit CPU Addendum as being a DMA2 (Direct Memory Access) controller.
If you look at the T unit schematics on page 3-14, CPU Sheet 8/22, or page 50/74 as listed in Adobe Acrobat, you'll see the pinout for the chip.
I have had a board on my bench with graphic corruption which was caused by popped solder connections on the pins of this DMA2 controller. It did not cause any crashes.
Also, check page 43/74, CPU Sheet 1/22, to see how they used the 34010 chip on the T unit. Data sheets on the TMS34010 can be found out at http://www.datasheetarchive.com
