This is known as the 'TAAC-1 Application Accelerator' p/n 501-1383 and 
501-1447 (later rev.) It looks to be a graphics co-processor type-card.

It is supposed to show up as /dev/taac0 under SunOS. 

FWIW from the notes in the last FE Handbook for Sun4 parts it says:

1.Do not disassemble the two-board assembly. 
2.The TAAC-1 is not supported with the Sun-2 Color Frame Buffer. 
3.The TAAC-1 is not supported with the CG9 Color Frame Buffer. 
4.Jumpers JB201-JB204 are hardwired for 16K x 4K RAM. 
5.TAAC-1 is not supported under Solaris 2.x (SunOS 5.x). 

These originally shipped with the 2/130 and 2/160 and were also found in
the 4/260/280/360/370/380/390/470/490s

>From what I can gather on various Field notices you'd run your graphics
output from your framebuffer (CG3/CG6, the p/n 501-1447 support CG9s)
through this card and then to your monitor. The field notices I found
explain that when people upgraded monitors and such they needed a new
set of cables (because of the move from BNC->13w3.) 

This is all 'book knowledge'-- has anyone used them hands-on?
