And: A reminder that I will be more than happy to help scan the SM's - heck, I'll pay (reasonable) postage to send back and forth.
My personal preference for the associated SN's (but not limited to) are the HP 3663A, 5335A, 5345A, 5245L, 3325A, 5105A, 5110B, 8640B, 8903A, 3456A, 3455A.? Again, while those are on the top of my personal list, I will of course help with any others that anyone wants.
Thank you all again,
Hal
