What is a PVK11-G/02 ????

While pawing thru the piles of scrap boards at the local junk emporium, I came across two identical boards marked "PVK11-G/02". They have the standard double high/double wide QBUS form factor and dark brown/black module handles. The only other identification I could find printed on the boards was "Made in Australia" - no manufacturer or module number. Each board contains a 6809 (!) chip, an Intel FDC chip, a CRTC chip, a row of DRAMs, a couple of EPROMS, and some other miscellaneous logic. Now, of course, the question is "What do I have"??? A quick web search for PVK11 turned up nothing. Thanks! Bob Armstrong P.S. If you can, please cc me directly with your reply - I read this list in digest form and I can't wait a whole day to find out!!!
