General: The passing of a friend

Peter Hemsley was a good friend of mine who lived in the UK.
I had known him for about thirty-eight years when we both became 'Telecoms Technician Apprentices' in British Telecom (then known as the Post Office as the same company was the national mail carrier)

During this time we both enrolled in an early computing night-class at South-East Derbyshire College of Further Education and rapidly gained skills in BASIC and PDP-8 assembler, both memory-constrained so we learnt to code lean and mean!

Later we both worked at S.E Labs in Sandiacre, Nottingham (which became a branch of Thorn EMI Datatech) in the field of instrument repair specialising in microprocessor-based instruments and analogue and digital multi-channel tape decks.

During this time and subsequently, we formed a business partnership, 'Amber Microsystems' specialising in the development of custom hardware and software. Much of our development work was carried out on Apple ][ machines which were our first (and much loved!) personal computers. I left my half of the company to Pete' when I emigrated to Australia in late 1987.

I didn't normally get a lot of email from this friend although I included him on all the techo' newsletters and occasionally sent him an update on happenings in my life.
For a couple of weeks I had email delivery failure notices from his mailbox provider and on further investigation, his domain seemed to be gone from the internet.
On last Monday (the 23rd Feb') my unease and foreboding prompted me to seek more information on his curent status.

Knowing that he was keen on Amateur Radio, I 'Googled' his name with 'RSGB', that being the body (Radio Society of Great Britain) that 'Ham' clubs are affiliated with in the UK.
Sadly, I found an obituary notice on the site of SNADARC, a club in South Normanton, a village close by his home and one of our old haunts. -

Peter Hemsley
It is with sadness we report that Peter Hemsley has passed away
recently after his brave five month battle with cancer.
A floral tribute was sent on behalf of the club and members were also in attendance at the funeral service at Mansfield Crematorium.

Searching the site for confirmation that this was the same person I found some pictures that indeed seemed to be of my friend and I sent off an email with a picture I took of Peter in April for them to confirm my conclusion.

Sadly, it was indeed my friend Peter that had passed away just before Christmas after a five month battle with cancer.
When I saw him in April he was pretty ill and said that he had Emphysema (bad enough in itself) but perhaps he got re-diagnosed afterwards.
I suppose that his preference for hand-rolled filterless cigarettes may well have caught up with him finally.

He was an elegant coder with a preference for assembly language and had a particular skill with numerical methods and an intuitive grasp of manipulating numbers in binary representation.
There are still several places on the internet archiving his fast and compact PIC microcontroller routines for Square roots and Decimal Input/Output that he originally presented in Everyday and Practical Electronics magazine.
A bit of competitive fun that we both enjoyed was each taking turns trying to improve the speed or reduce the size of a piece of code until no further improvements could be made. I think the score was about even (well, that's my story and I'm sticking with it!).
He was similarly economical when it came to hardware design and contrived some very nifty microprocessor-based designs and single-sided PCB layouts with minimal interconnects.

I will miss him a lot for his sense of humour and steady friendship.

This is the last photograph I took of him as we wandered around Anchor Surplus in Nottingham in April 2008 chatting about how we used to actually work on half the old stuff there in our younger days!
