Not sure what you meant but yes, you can cause the display to scroll so that you see the entire number. I'm pretty sure it can do 64 bits but it might be more. Haven't used my HP 16 clone enough to remember how to do it. I believe there is also a setting for how many bits will be used in logic and arithmetic operations.

I own an WP34, HP48GX, HP25, but using a 4.99 DEM calculator I bought 35y back in a supermarket.

..Many old HP calcs go belly-up if you put a charger in them without the battery...

Does Moravia fix both 16 and 15CE bugs?
The first thing I did with my HP25 after I got it I installed the protection zener..

It seems to take up less room on the desk plus the retro aspect. I still bugs me that HP released the 15CE with the bug in it.
The 15CE sold out quickly, you really had to be lucky to get one in the first batch of 10,000, I think it was. I ordered within a minute of the sale opening and I had found that by accident one evening. I paid $99 for it and within a week they were selling for much more unopened. You can get one for that price again sans box. The original 15C is pretty pricey and you have to look hard for one without dents.
The 16C is a great calculator but the hex and binary word sizes are really too small to use effectively. Maybe there is a display digits setting I am overlooking.
If someone gets interested from this thread, The Museum of HP Calculators is the source for information on all things HP calc related.
By the way, I found the overlays to turn the Dm42 into a C47, pretty cool.

Yes, I can see that - they could have picked a better name though.
I used to own a 16C myself. For the price, I was always a little disappointed that they only used a 7 segment display when dot matrix, or at least starburst were available - but of course they were all the same calculator hardware with different coding and overlays.
RAPo:
Yes, a selectable max word size of 64.

I didn't really care whether it was a "collector's edition" or not. The HP15C has been out of production for a long time so prior to this, the only way to replace (or have a backup for) an HP15C as to buy used at a crazy price or buy a clone (like the SwissMicros I have, see above)
Strangely, the HP12C (the financial version) can still be bought new at a reasonable price.
