Wanted hp-11c
Hello,
Anyone willing to offer a hp-11c and ship it to Spain?

I'm looking for a scientific traveller series calc to replace my tired hp25. Of course a 15c could fit also if the price is affordable.
I'm not a collector, so manuals or other material but the slip case aren't required.
I know some of these can be found regularly in the auction site, but I'd prefer to buy to any trusted member here if possible.

Thanks in advance
J. Alonso

Hi, if you not a collector you could consider the DM11L or DM15L from Swissmicros.com.

Quality is great, prices are surprisingly low. These are using the original OS running on emulated hardware.

It ain't OVER 'till it's 2 PICK

Thank you HP67.
I really appreciate your advice. I'm not a collector, sure, but I'm an old style hp calculators feel and touch lover. Of course I know about swissmicros replicas (mainly thanks to this forum) and recognise the effort done, but still would prefer the pleasure of owning an original well cared original hp if possible.

RE: Wanted hp-11c
Sure, I understand. In most cases it's expensive to get the models we want in good shape. I have several Swissmicros and gave several as gifts. They are the next best thing to "real" HP calculators and in some ways are better. So get both if you can!

The fullsize Swissmicros models have titanium cases and have a great solid feel. Much better than I expected.

The full-sized DM-1xL models' case is actually made from stainless steel; the early small models were titanium, and I think they changed to steel as well, but am not sure.

And I agree, they are delightful and satisfying in every way, with the exception of not being genuine HP machines (but if they were, they would not be 20 times faster, have USB ports, etc. Smile )

Only 20x faster ?

The DM42 is 50x (battery) or 130x (USB power) faster than the HP-42S, and any original HP Voyager series calcs are much slower than an original 42S so any SwissMicros offering would be expected to be relatively much faster than only 20x.

Are you sure of that lowly figure ?

Good catch Valentin! I was referring specifically to SM's Voyager models, but '20 times' is admittedly a rectal-pluck. A quick check of an original 1985 12C compared to a DM12L, doing a simple loop adding 1 for 1 minute, reveals a factor of about 23 times faster. I'm actually surprised my guess was as close as it was, it was really just an attempt to convey a whole bunch faster.

I suspect the NUT CPU emulation layer on the DM1xL models uses a lot of extra cycles to execute the original HP code. The DM42 is running native Free42 HP-42S simulator code compiled for the
ST32L476 controller with no emulation layer. The DM42 ST32L476 controller also runs at almost twice the clock speed as the LPC1115 CPU used on the DM1xL models.

They still show the 16L as having a titanium case IIRC. I have a 15L also, and I did not notice any steel cases nor was I aware of this change. Hmmm, the plot thickens!

You (and the website) are quite right. The SM machines have cases made as follows:

CC-Size Voyager have a Ti bottom case (though none are currently available)
Full-Size Voyager have a Ti bottom case and Ti LCD bezel
DM4x: Stainless Steel back and stainless Steel key bezel (painted)

When the DM4x models switched to SS, I thought the Voyagers did as well, but that's not the case. Sorry for the bad info.

Hi,
Thank you all for the advice given.
I've locally found a 85' 11C in very good working and aesthetic condition. More than happy with it...

RE: Wanted hp-11c
I'm glad you found a local source. My HP-11C was a dumpster find! (And in great condition, with manual).

Try CC41!
