After 27 years, there are still some surprises with Series 5mx. It turns out that the Psion Series 5mx PRO BootLoader contains an easter egg with credits. It seems no one knew about it (excluding the authors) for these years. To call this window, just type 'about' while BootLoader waits for a CF card or YMODEM transmission.

In a review of all of the CF cards I have been buying to try and find some that will work with my hp100lx. I have found that I have only gotten two that actually work. The other ones say not detected and don't work in my system.

When I use a disc partitioning utility on a modern Windows computer I don't see any difference that shines a light on why there's a problem.

Do any of you have experience on what might be different inside these compact flash cards? Does it come down to the controller? Or does it come down to some sort of formatting?

For those looking at the pictures the only ones that work are the two on the left that have the labels on them. All of the other ones are not detected no matter what hoops I try and jump through.

I was buying CF cards from all over to try and find a 256MB CF card for my HP 100lx

Today I received from AliExpress a 256MB card that does not require an additional drive to function.

It was detected by fdisk100 with no need to wipe or any other tricks from a modern computer.

I'm super happy with my find.

What storage solutions are you proud of for your retro systems?

I've just this Psion thingy from the flea market and it works if I plug it to power It runs Symbian. I quite like it. I plan to replace the battery and carry it around but I don't know german... Also, can you recomend me some software and games for it?

I had an old Motorola i930 and decided to get it working again. I have an old T-Mobile sim (Pre-9260), but the phone was locked to Nextel/Sprint and wanted a subsidy code. I was able to find a bunch of resources online and after extensive use of the wayback machine to download old zip files, I was able to De-cert the phone in order to be able to install regular unsigned Windows Mobile applications, there was also a subsidy unlock program that I found that, once the phone is De-certed, you can just plug in the phone and it will read the code and tell you what the code is, so that you can input it once you put in the other carrier sim. I also found the utility that allows you to install Java apps on the phone using the computer, as it is a different method from installing windows mobile apps. I also applied some registry hacks to change what ambient light level the keyboard backlight turns on at (hence why its off in the pictures), move IE temporary files and MMS/email messages to the SD card, loop alarms so they don't automatically turn off, and other small changes. I also found a utility that can update the firmware to the latest version, but mine was already on the newest version so I didn't need it (Be cautious with this one though, it requires a special serial flash cable but there is a way you can get it to work with the normal USB cable but if done wrong it will brick the phone). There is another tool to subsidy unlock the phone called GeminiUnlock but it requires you to put the phone in flash mode and I was going to de-cert the phone anyway, so I found it easier to just use the subsidy unlock program because you can just read it while the phone is on in normal operation. I don't know how to upload zip files to Reddit so you can just message me if you want the files, I also have some programs like J2ME discord, J2ME weather, Opera Windows Mobile, SP TaskManager, Wordpad, Stopwatch, etc. Im also looking for more useful Windows Mobile 2003 Smartphone apps, so if anyone has any that they know of, please tell me. I also can't figure out how to install .NET compact framework 3.5, as some apps I tried wanted a newer .NET version, but the install keeps failing.

I had to setup a DNS server and do a bunch of screwery to get it to connect to the NINA servers, but it works!
