Top of head thoughts, Compulytic = Computer Grade Electrolytic ?
32D - sounds like a type reference ? 4500 - 150 DC = 4500 uF 150V DC ? Strange though as 4700 uF is the usual value and 100V or 200V are the usual nearby voltage ratings. 7230L - maybe the part number ? 0180-1839 - maybe the HP stock number ? My guess is that Sprague supplied these as "specials" to a HP spec. This sort of thing happened a lot when I was with RCA. 73 and good luck, Geoff.
