True, it can be done that way. You save keys but lose useability.

I recently got a "dummy load" board (actually has the same LCD on it) which implements its functions with three buttons. Up, down, and Enter. So to dial up a load of 4321 you hit up once (for the 1) then Enter to move across to the 10s column. Then up twice (for the 2), then Enter and so on. It's a bit tedious but it works.

Yep, in my phi buttons class, I even have auto buttons that get pressed automatically at a fixed interval. Use one of those as up, employ cyclic order on 0-9 and you just need one real button, right/enter to do everything, if you have patience. Ultimate time division multiplexing.

and even books

Hmm. I've done a lot of pitching with various "downsizing" moves. But I might still have some old DEC books around. I really liked working on PDPs, and I'm pretty sure I kept a few things for nostalgic porpoises. Actually, I know I have a PDP-11 architecture handbook, and pretty sure a VAX architecture manual. Whether I can find them is a different question, as most of my books are boxed. I think I still have a Macro-11 programming card, and maybe a VT-100 card too. (Those are 8.5x11 card stock, printed landscape in a tri-fold configuration.) Part of me doesn't want to part with them. Yeah, nostalgia. smiley

Sometimes I wish I had kept one, just one, punched card (to show people).

Also a CRAM card.

I spent very little time with punch cards. But I have read this poem.

How old is old? And what constitutes "computer stuff". I have an HP PocketPC that I believe is in working order but it's from around 2001ish.

Thanks for asking. I believe I referred to era between 1970 and 1999 (let's cut off around PIII-800 smiley) I need them only for my collection and future display so they need not be operational but should look decent. I think an HP PocketPC might be a little new. It has maybe 300-500MHz processor and runs some simple excel, adobe reader etc, right?

Just looked up specs.

It's actually a Toshiba e300, e310 or e330 (can't remember which right now)and not an HP.

Looking it up online it's an intel processor and either 206Mhz or 300 depending on what model.

But yes, it plays music/video, displays pix, takes notes and you can open and edit work and excel docs.

I remember that era. One friend of mine got an HP model and was showing off that he could use some mathematica or else on it. I think I'll pass. I want to concentrate on computer processors, books and computer games. I already reached out to calculators and type writers, with one of them sitting in my car trunk. smiley-sad too much stuff, too little space, who am I joking?!
