Help Identifying Vintage HP Boards?

Hi all, I'm new to SMF but have lurked around here plenty of times through my scrapping and e-scrapping days! I've decided to get back into it and join up.

I'm hoping some of your resident experts can help me ID these beautiful looking boards I got at a thrift store. I'm hoping some of them might have more than scrap value, but I'm having a helluva time trying to find any info on them. Most of them are heavily populated HP boards with lots of gold. If anyone has any info on them I'd greatly appreciate it! I bought each board for $2 to $3 each hoping in some resale value.

I would upload pics, but it looks like I can't do so as a new member!

I also have a few Parker Digiplan boards that are listed for $150 to $300 each on ebay with no sold listings.

Parker Digiplan UDPS/UIC 44503101 Rev:A DC Drive System Power Supply
Parker Digiplan UD2/UIC-203 Theta Power Amp 44866203 Rev B
Parker Digiplan UD2/UIC-204 Z Power Amp 44866204 Rev D
Parker Digiplan UD2/UIC-201 UIC Transfer Amp 44866201
Any info at all would be greatly, greatly appreciated! I've never had boards like this come in before, as I'm used to buying lots of desktop towers to tear down. Thanks a bunch!
