Well.. the HP33's have arrived from Bert. Once again - thanks so very much Bert!
I've just dismantled the 33C and refurbished it inside and out. It's clean as a whistle (down to the last key) and works wonderfully on 1.5v AA's. I'll go down to Jaycar tomorrow and buy some new 1.2v NiCd batteries for it and the 33E, which I'm just repairing (re-rivetting and soldering) the spring contacts on before it'll go too.
The 33E is a fair whack heavier than the 33C which surprises me. It's of totally different construction internally, with removable LED array and steel-encased logic. Looks like they really revamped their construction techniques on the 33C and made them lighter and I dare say more cost effectively.
The museum collection has started, and Bert - they've come to a good home.
Cheers
Chris
