If it's like the rest of the Psion line, it has its own language called OPL.

RE: Psion HC 110
Can the processor be addressed directly, if that's the correct terminology, with assembly language?

Hi, you can find the HC programming guide here http://basic.hopto.org/basic/manuales.php
I think than you can also program an app on OPL in any of the other psions pdas in one of the Solid State Disks, mainly series 3 and MX, compile in them and then change the SSD to the HC to run the app. Although I have all this machines, including the HC, never tried.

Just Googled for PSION HC 110, the first pdf was this:
(I hate Google on phone, it can't copy the link of the downloadable stuffz, but the site is: http://oldcomputer.info/index.htm)
UPDATE: http://oldcomputer.info/others/psion/HC-PG.pdf

You can find there:
CHAPTER 2
WRITING SOFTWARE FOR THE HC
Basic programming choices
Choice of programming language
The two main high-level programming languages for the HC are Opl and C.


I have one somewhere, as I can remember it has a DOS (or something DOS-like) on it, I guess as a shell. I never used it and not really liked.

Btw: good luck!

As others have stated, it's OPL Smile

I myself have a Psion Series 3a that's in need of repair which I used many years ago, when I was only about 15 years old or so. I have fond memories of programming graphics algorithms in OPL on that little machine when I was on a road trip Smile

Yes -- it's a custom 8086 chip. But, the OS uses preemptive multitasking with message passing IIRC. The OS is Epoch 16 I think.

RE: Psion HC 110
Thanks all for the additional posts! The HC 110's shape reminds me of the Corvallis-Micro-Technology-MC5GT I used in 1994 on an FDOT project in Palm Beach County, FL. It had an environmental case and an air release valve for those who worked at higher altitudes. I think it was programmable in BASIC. I don't think it ever crashed on me. The attached picture is not the MC5GT I used.
