Wanted: DEC Rxxx module photos

Hi, Today I have finished documenting the Rxxx "flipchip" modules in my possession. These are the modules from which most straight-8 and PDP-8/S gear was constructed: http://www.so-much-stuff.com/pdp8/flipchip/flipchip.php http://www.so-much-stuff.com/pdp8/flipchip/Rxxx.htm The Rxxx modules are a smallish subset of the larger DEC modules space: http://www.so-much-stuff.com/pdp8/flipchip/modules.htm Unfortunately, there are several Rxxx modules for which I have neither example or picture: Module Versions Description R211 K* L* MB, PC, MA, (PDP8) R212 A* J* MQ (PDP8), 2 FFs, SR, SL, Read-in, Clear R220 F* L* 3-Bit SR, Parallel Read-in, Diodes out for detecting all 0s in R111 node R284 A* Quadraflop, PDP8, 4 stable states R450 D* E* Clock for use with TTY, first pulse comes 1/2 period late R451 E* Teletype Clock, for faster teletype think R450 R601 B* F* H* Pulse Amplifier, 6 DCD Gates, 100 or 400 ns pulses R613 B* R603 that cannot be triggered from output, with 5 mA loads R650 E* Bus Driver, 2 circuits, 2 Inputs & Node (* just means I don't have a board drawing for it yet) There are also some more exotic modules for which I lack even a schematic: R012, R1110, R1130, R152, R200, R406, R407, R408, R623 and I don't expect to be able to locate or do much about those. Anyway, what I'm looking for is some help with the former list. If anyone has examples of these, would it be possible to photograph the component and solder sides with decent resolution and forward the photos to me? (You are welcome to forward the whole module, but I don't expect that :-).) The version information just refers to versions that I have schematics for. Any version you have is fine. I am particularly interested in the R2xx, as those are key modules for the straight-8. Thanks in advance for any help anyone can provide. (Meanwhile, I'll start drawing Sxxx modules.)
