The “Personal Digital Assistants”, devices which dominated the 1990s and early 00s with their portable computing capabilities. A large variety of architectures and OSes are found in this realm. MIPS, ARM, and m68k are just some of the architectures found here, with OSes ranging from PalmOS, Linux, Windows Mobile, and more.

It is possible to telnet, FTP, and make remote X connections to the device.

One of the first, if not THE first Linux-based PDA. Since it supported Linux natively, it’s not surprising to see various EOPs available for it, such as games and typical PDA software.

runs with Newton OS 2.0/2.1 on a MP120, MP130 or MP2000; It also should run with a MP2100

Supports GIFs, and covers various OS versions across a few models. Unsure if it still works.

Many PsPC machines are used by the developers for active development

Quite like the NetBSD port to MIPS-based WinCE PDAs, the NetBSD port for the ARM-based WinCE PDAs is both robust and concise. This port is still supported as “Tier 1”.

Not working: - Keyboard

Just one hack done for this thing, which is a weird smartphone/PDA hybrid from the mid-late 00s. Normally runs Windows Mobile/CE (unsure of right term), but Linux was hacked onto it, complete with X.Org support.

I started porting to the PV-S1600 platform a Web Browser (the Adam Dunkel's Contiki project

The most impressive part of this one is that it has the web browser. Not sure if it can actually get to the internet, though. May not be a full Contiki port.

OS - roll out own. I started work on one and I am now reverse engineering the bootloader

Unsure if this even got ported onto the Classic, but there are actual files made for it. Even if it isn’t ported, there’s a lot of information at the dbzoo wiki page.

There is not enough RAM and flash to run Linux (at least not on the classic)

Postulations, seemingly not possible. Some useful talk about TCP/IP stacks, though.

enter commands on the keyboard, read the results on the screen via a framebuffer console

Successful operating system port, serving more as an example of what is possible. Slow, but works.

It seems that many Zaurus programs that depend on X11 can be made to work on the iPAQ. YMMV

Since it works on X-Window , iPAQ has introduced it so far

Almost certainly based off the Zaurus port’s sources, as they both depend on using X11. Thus, this port of Basilisk II requires X11 + Linux to run on the iPAQ.

This device runs an operating system which is known to emulate various devices with EOPs. See the Classic Mac OS page.

Familiar GNU/Linux distribution is made up of packages that can be downloaded and installed

The baseline port for a significant fraction of EOPs for this device, but not all. Details and level of function are a bit hazy, but it is capable of running programs. However, it may not be possible for it to remain permanently on the device, ie. it will have to be loaded on upon every restart.

Because of the hardware platforms it supports, NetBSD/hpcmips is an ideal platform to use

Appears to be the most concise port for these devices. Many processors and machines are supported, to the point where listing them all individually would be pointless. Check the page for device specifics and information.

Various ports of uCLinux to various Palm OS handhelds. Many support framebuffer, boot, and shell, while others fail in some capacity.

Whether these emulators support operating systems for these computers is unknown; it must be looked into further. PCs without meaningful OSes are not included.

Don't dream about completely replacing winCE with linux

Ported to various devices, such as the Velo 1. All ports appear to be dependent on the Windows CE subsystem, but they still will run on these devices.

The easiest way for now is to use the Flash Tool from official flashing guide

This device, being a modern take on the PDA (a phone without cellular and with a keyboard), understandably runs postmarket. Of course, with it’s keyboard and practical function not found in typical devices, it’s worth listing. Not everything runs perfectly, like the Wi-Fi.

https://wiki.postmarketos.org/wiki/Planet_Computers_Gemini_PDA_(planet-geminipda)

Similar to the PlanetComputers Gemini. It runs something, and it came out only in 2021. Details are minimal for now.

primarily the Series 5(CL PS-711x), Series 5mx(Windermere) and Series 7(StrongARM)

An experimental port that requires a custom executable meant for the OS, which appears to be available online. While the original EPOC OS for these devices is based off of an ancient Debian version, this NetBSD port is supported up to the most recent NetBSD version. Not all PSION devices are supported, and the touch screen + sound do not function yet.

https://www.reddit.com/r/NetBSD/comments/e3iuri/epoc32_loader/

Many kinds of H/PC, H/PC Pro, and PsPC systems are supported by NetBSD/hpcsh

Similar to both the ARM and MIPS ports for WinCE PDAs, this NetBSD port is concise and supports a large group of PDAs with this architecture. More details are on the linked page.

I have kept both bin files incase Basilisk II 1.0 breaks something that 0.9 ran

One of the most functional PC operating system emulators for the Zaurus. Confirmed to run OSes, thus it is given a separate listing.

Whether these emulators support operating systems for these consoles is unknown; it must be looked into further. Consoles without meaningful OSes are not included.

SL-Axxx, SL-Bxxx, SL-5×00, and SL-6000 series are not supported

Still in existence, this port of NetBSD appears to support all SL-C Zaurus models, and no others. Most peripherals work, with a few hardware features non-working.

http://wiki.netbsd.org/ports/zaurus/

The OpenBSD/zaurus port was discontinued after the 6.0 release.

Stable, functional, with internet, X, touchscreen, and much more. One of the smaller SSH capable machines at the time of porting.

This is a handheld computer from the modern age that can run postmarketOS, alongside (presumably) a ton of other OSes. You just put it on the SD card and boot!
