The full source code is available in these archives (it will not compile unless you get the correct assembler and stuff):

The subversion tree can be obtained like this (you may not have access to this repository; contact UBC); 

svn checkout svn://e-mode.phas.ubc.ca/arc_pci

It is laid out roughly as follows: 

/trunk       main line of development
/releases    tagged versions of code 
/tools       debugging tools
/clash       stuff for making CLAS work with wine and linux
/docs        useful (though maybe not to you) notes

Firmware version notes

U0106 (2011-11-21): Recommended version

  • Backward compatible with U0104 and U0105.
  • Fixes bug introduced in U0105 that prevented handling of some PCI bus errors.
  • Introduction of command to update PCI burst size.

U0105 (2009-06-08): Stable version

  • Backward compatible with U0104.
  • Support for MCE STOP commands and commands-on-the-fly.
  • Accelerated MCE command code (along with Quiet-RP this increases commanding rate to ~6 kHz).
  • Quiet-RP simplifies the protocol for MCE reply handling.
  • Low-level improvements:
    • CON is done as PCI burst
    • Fibre-optic FIFO is emptied with timed read instead of polling.
    • Hand-shaking for interrupts instead of host command to clear INTA and HC3.
    • Non-interrupt context code disables interrupts when performing PCI transactions.
    • Host vector interrupts are otherwise enabled, so PC doesn't have to force with HNMI bit.

U0104: First version with non-realtime linux support

  • Implements quiet transfer mode! Remains backwards compatible with A1.4.
  • Fixes the 64k boundary crossing issue
  • Moves parameters that enter via interrupt out of registers and into variables
  • Version reporting tag-along to RDM command (sending 'VER' to RDM's vector address returns the code version).
  • Maximum burst length is reduced to 64 bytes, and is configurable.
  • Reset (RST) clears the fibre fifo

U0103: Oldest UBC release

  • Minor modifications of SCUBA2's A1.4 firmware, to improve PCI stability.
  • Not compatible with non-realtime systems.
