Testing, finding syntax errors, then more testing. They tried lots of more direct methods, even flashing squares on the TV, to send data, and 'floppy records', you could play on a record player. My original partner, before she became ill, worked at the local hospital's patient record...

Mine had a special version of 8K BASIC, and 8K machine code Assembler, all in 1K 2708 eproms. I quite heavily modified both, myself. I don't remember there being a 26 letter variable limit, perhaps it used AA to ZZ? They were the fun, entertaining days of computers, everyone involved was an...

I think, you need to get actual trades in there, to look at the job, and decide just what needs to be done. You, need to be armed with some idea of what the end result is, that you want from the site. Any replies you get on here, are pure speculation.

No, that only applies to the indicated speed, the speedometer. There is no standard I am aware of, for the odometer accuracy. I have access three speedometers in my car - The default analogue dash, a digital version which is direct reading, and the satnav. The analogue dash reading is...

That should be simple enough, given enough information. What voltage, ac or dc, and current is powering the coil of the relay, and what current and voltage does the relay need to switch? Do you perhaps have a circuit diagram, which shows how this relay is installed?

Forward planning, would have made that so easy.

I did think about it, when I sold the Viffer, but its storage space is now occupied by my mobility scooter. Besides, it occupies me enough already, looking after the house, car, caravan, scooter, and tractor.

My mother - a proper, entirely home cooked Sunday dinner, always beginning with Yorkie puds, an occasional evening rabbit stew with homegrown tasty carrots. I've only once had rabbit stew since then and it was horrible. Sometimes, she would make a meat and potato pie. Years later, she would...

Nope, not at all!

Lag only where the pipe heat loss might serve no purpose in warming a space, or where less warmth is needed.

Spot on!

That is similar to my recollection, I remember buying an early Nokia, in around '93, on Orange. The weird Orange TV ads, just mentioned 'The world being Orange', with no explanation of just what was orange :-)

I did similar, except with an 8080, and static ram up to the limit of a massive 64k, but wrote a rather clever word processor, in BASIC. The BASIC, rapidly ran out of ram, so I ended up having to design a 'memory paging system', a sort of precursor to what the BBC eventually made good use of...

To a large extent, yes! The spring pressure, would take up any slack, from the lead deformation, whereas a screw terminal would simply remain lose, until someone came along and tightened it.

Lead, is much more 'fluid', than copper, or brass, both of which are much more resilient to deformation.
