Citroens still had starting handles in the 1970's (it was a dual purpose wheel-nut spanner). I started my father's one a couple of times with it, but starting handles and modern high compression engines (even in the 1970s) are not a good combination, and I don't think most drivers would have been able to turn the starting handle at all. Wouldn't surprise me if they were responsible for more heart attacks than started engines;-)

The one in which I learned to use a cranking handle to start a car in the '60s and in the '70s was still using the cranking handle to turn the engine round when setting the rocker gaps.

Can you index the indexes?

If you don't want to repair it there are plenty of enthusiasts who will. Many of which will not return the unit however.

Yes, and there are emulations of the old HP 35s, 45s, and others many of which vary in their conformance. Not the same as getting the old hardware working again is it?

For John Larkin:

If you want to find out how much code any EXE file has, do the following commands:

GET FOO.EXE CORE

It should report how many K there is. But this doesn't give the real size when the EXE is running.

Indirect addressing seems to be politically incorrect these days, along with the "execute" instruction.

The seventies (the early seventies) were the peak of octane ratings and compression numbers. Unleaded, low octane fuels means that you will not see an engine with higher than 9.5 to 1 compression these days.

The early seventies was the peak with numbers like 10.5 to 1 and 11.5 to 1. Those days are long gone.

Or just PIP FOO.EXE/L ?

My HP-45 still works - sorta. The power switch is flaky and I haven't gotten around to try to "replace" it. I bought a new set of batteries a couple of years ago and a couple of frame gizmos so I can make my own packs. eBay is useful for something.

I bought one a year and a half ago. I like it, but it's no '45. The function placement just isn't "right".

I'm not sure what that would even mean...

The few cars I've had with adjustable lifters have used a wrench for that...

The worsy thing about the 35s is the erratic power switch, a sliding thing on a pc board that likes to crud up.

I bought a new set of batteries

Yeah. They should have done an exact clone. The newer stuff has too many overloaded buttons, too many functions. On my 32sII's, it's hard to find basic stuff like pi. And nobody needs a programmable calculator any more.

One thing on my to-do-probably-never list is to build a true HP35 clone.

Looks like a good nickname for you.

You can put your own firmware in the new 20B, but the keys suck. (For instance, someone did firmware to simulate an old 45 on the new 20B.)

The latest 12C calcs are using the same CPU as the 20B, so there's a chance for custom firmware. I'd like to emulate a 16C or 15C on it, but the key labels would still be wrong.

Chuckle - good one.

You couldn't do that to the cars I owned back then. I had to use a three foot breaker bar to turn the crankshaft on those old Pontiac V8 engines.

You can\'t have a sense of humor, if you have no sense!

I've never seen a Citroen in the US.

I think the Auto Museum in Saratoga hosted a Citroen convention last year.

unreliability.

They're unusual, but not all that rare. (Maybe you live in a rust-belt state where cars don't last as long as here?)
