This month we will be welcoming Clive Semmens as our guest speaker, who will be talking about his 30 years of working and playing with ARM processors.

Starting from when he purchased an Archimedes computer for a classroom in Stornoway, all the way up to the present day still using them in retirement, writing programs for RISC OS such as his Draw to SVG converter, and now a regular contributor on the RISC OS Open forums.

In the middle of that long period, Clive spent ten years working at ARM, where he was the senior technical author on the ARM ARM, that is the ARM Architecture Reference Manual. Clive is happy to answer questions about this and any other aspects of his 30 years up in ARMs!

Entry to ROUGOL meetings is free, food & drink plentiful (but not free), and all are welcome.

Question for Clive:
When you worked for ARM, was there any people there who wanted to help RISC OS improve? All water under the bridge now, but just curious.

Probably a few, but I don’t know. I knew a couple of other people who used it, but I don’t know of any concern about improving it. I wasn’t the only person who had a RISC PC alongside my PC under my desk, but as far as I know we were all running old software and original Acorn-era RISC OS.

I didn’t do anything beyond that until the Pi came along myself.

This was my set-up until the Pi arrived: http://clive.semmens.org.uk/Photos.php?Assortment%2FRiscPCs

Forgot to say, there are some photos from the meeting and a copy of Clive’s words and pictures up on the website:

Words and pictures also available at: http://clive.semmens.org.uk/RISCOS/index.php?ThirtyYears – now working satisfactorily on NetSurf (I think – do let me know if there are issues, apart from the title frame getting duplicated on NetSurf. Don’t know why that happens – it doesn’t on any other browser.)

I’ve been looking at that title frame duplication problem. I’m pretty sure it’s an error in the way NetSurf handles framesets – but those really should be obsolete anyway.

Fixed. NetSurf interprets the target=“_parent” attribute differently from everyone else. In these particular cases I can use target=“_top” instead, which NetSurf interprets normally.
