3. HP17B/17BII/19BII/27S/28S/42S: emu42

(current desktop and Pocket PC version: 1.09 and 1.08, respectively; note that the page at hp42s.com lists OLD versions. HERE is the manual.)

As with later calculators (the above-introduced emu48 and the HP38/39/40/48/49), there is an all-in-one emulator for the HP 17B, 17BII, 27S, 28S (1988, semi-graphical: 137*32), 42s (weaker Wiki page HERE; released in 1989; still WAY worse than the TI-89 – for example, no real graphing).

It uses exactly the same approach to KML files / skinning as emu48; that is, if you do read the emu48-related first chapter, then, you won’t have problems deploying for example new, additional skins from the homepage (for example, the VGA 42S skin, SKN42SMV - since version 1.02, it also supports VGA resolution). Fortunately, as opposed to Emu48, it requires no tricks when installing – no need to manually copying KML files etc.

Note that, unlike with Emu48CE, you must download the ROM’s from your calculators manually – they aren’t available on the Web (don’t even try to run a Web search for the ROM names in the KML files.) If this is a problem and you need to emulate the 42s, I have some great news for you: there is another 42s emulator, Free42, which does not require a ROM image.

4. HP42s: Free42 1.4.36.

As has already been mentioned, as opposed to Emu42 discussed in the previous chapter, this emulator does not require a ROM image and may be used even if you aren’t a rightful owner of the original emulator.

There are two versions of the emulator: decimal and binary. The latter is much faster but, because of the internal representation differences, may not work with some legacy applications. If this is not a problem, install the binary version (copy and execute it there to install). Also see the section “What's the deal with the "Decimal" and "Binary"?” in the README.txt coming enclosed in the ZIP archive. The two versions can co-exist without problems on the same machine and, therefore, you can always go back to the decimal version, should a given application refuse running.

(the same with the “realistic” skin, which is pretty blurred because of the low resolution)

Note that, as with the ROM’s, the original, official manual of the 42s isn’t available on the Web either (as opposed to the 39G/40G (CAS)/41C/48G/49G+ series with manuals online); however, there’s an unofficial ‘fan’ manual HERE. The latter manual is very easy to understand – actually, I’ve found it much easier to comprehend than HP’s official manual.

Compatibility-wise, you can use the numeric keys of devices with built-in keyboard. It’s not compatible with the Landscape mode. It’s capable of importing / exporting programs. And, finally, good news for QVGA Smartphone users: if you copy the executable file(s) (after manually extracting it/them from the CAB file(s)) to your phone, it’ll run flawlessly. The numeric (phone) keys will work OK; for the rest of the keys to access, you’ll need a cursor emulator like SPHelper. Example screenshot or it, running on my HTC Vox / s710 (the cursor is that of SPHelper):

Of course, this only applies to QVGA Smartphones - traditional (176*220) models will only show part of the skin and are, consequently, useless.

5. HP-16C

This calculator, mainly meant for computer programmers needing for example binary / hexa conversions, was manufactured between 1982 and 1989. Also see THIS for an intro to this model. It only has one emulator, CP16 (direct download links HERE); the current version is 0.326.

Installing and using this emulator is pretty easy: you download the above-linked ZIP file, extract cp16_ppc.exe from it, transfer it to your Windows Mobile device and start it from File Explorer (you can, of course, put a link to it into \Windows\Start Menu\Programs).

Compatibility-wise, it’s not Smartphone-compliant. It has built-in support for Landscape (View / Landscape); for it to work, you must start the calculator in Portrait mode because the emulator only rotates the GUI for itself, not on the OS level. This also means you won’t be able to use it in left-handed Landscape mode (the native mode for the Universal, Wizard, TyTN / Hermes and all other Pocket PC’s with a slide-out keyboard) unless you use a third-party hack to rotate the Portrait screen with 180 degrees before starting.
