The 1620 was later resurrected in the Forbin Project movie as Colossus. I was hooked on computing (hardware) after I discovered the well hidden secret drawer under the console desk where the admin's hid all the manuals and paperwork. >>My >>first calculator was basically a mechanical "adding machine". >> >>I eventually ended up with an HP-35 RPN calculator and loved it.

I'm lazy. For anything complicated or highly repetitive, I use Google search to find a web app or dedicated calculator for whatever I'm trying to calculate. It will probably be written in Javascript. I can usually find a suitable online calculator for almost all the electronic calculations I might need. If I need something obscure or can't find anything, I'll scribble something for the occasion. I'm currently dabbling with AI code generators. I'm a rather bad programmer, so learning will take some time. >My first and only HP calculator is a HP 200LX, still working fine. I had an HP95, HP 100LX, and a HP200LX. I still have the HP100-LX, but the others were sold long ago. Trying to find PCMCIA cards with small amounts of memory, is what forced me to stop using them. They were really "cool" in their day. >I >lost one of the tiny case screws, decades ago, replacing the CR2032 now >and then is still awkward.

I'll look for a screw and mail it to you. Otherwise, there seem to be some available online: I removed one screw from my HP 100LX to check the size. I would guess(tm) it's 2-56, but without a gauge or a 2-56 nut, I can't be sure. However, I can't find my thread gauges and my microscope threading graticule is in use. So this will need to wait. Please remind me if I forget. >Getting back to cycling ... :-) Sorry. I need to get back to house cleaning and firewood hauling. I'll read through the rest of your posting and write something, hopefully in a few days. -- Jeff Liebermann jeffl@cruzio.com PO Box 272 http://www.LearnByDestroying.com Ben Lomond CA 95005-0272 Skype: JeffLiebermann AE6KS 831-336-2558
