The first handheld calculator was a 1967 prototype called Cal Tech, whose development was led by Jack Kilby at Texas Instruments in a research project to produce a portable calculator.
John Blankenbaker's Kenbak-1 was the first personal computer. Designed in 1971, before microprocessors were invented, the Kenbak-1 had 256 bytes of memory and featured small and medium scale integrated circuits on a single circuit board.
@ChrisLuxembourg I received a letter from Clive when I was about 12, I wrote to him saying the C5 should have some sort of regenerative drive system to charge the batteries
There is already an answer used over many cities worldwide... it's called the bicycle, made to the standard diamond shape frame. If he had simply made a power assisted bicycle with improved battery technology and motors he would probably have cleaned up. The reason there aren't many recumbent bicycles on the road are due to stability, practicality, and/or visibility.
The C5 was a bad design from the start. It had no seat adjustment for tall or short people and only a single gear. I like the looks, but it just wasn't practical. The X-1 looks promising if they've corrected the mistakes of the C5 program. I'd like to get one. I hope he restarts the project.
+TrueBlogge777 I am surprised a genius like Clive can't see the obvious fact this invention NEEDS to be 3 wheel, and good luck if one of those tiny little tires hits a medium size pot hole (yuck). This idea would be another flop if he released it to market without some serious re-designs.
I love his gadgets, pitty he no longer makes computers, i'm still hoping one day his company will release a ZX Spectrum type gadget that plugs into a HDMI socket of a TV and its got 200 of the speccys most poular games stored inside. That would be a dream come true.
unfortunately for sinclair the c5 was waaaay to ahead of it's time. He was thinking 10 years ahead of everyone else. It just wasn't going to fly back when gas was cheap and the car was now overpopulating the roads as much. But now this is a very ideal form of transportation.
people's problems are not the bike , it's there's not good enough infrastructure , and unfortunately till we have that , you won't get people out there cars .
+TrueBlogge777 Wrong the smaller the wheels the less torque it takes to turn them + hot electric motors are inefficient and suck more amps. Wrong because the radius of gyration is raised to the power 3 so the larger the wheel the more energy it takes to turn it from 2x2x2=8 3x3x3=27 so the bigger it gets the worse things become as far as energy consumption goes. Emotions and preconceived ideas will always clash with inventions that are based on mathematics sadly the majority of humans are emotional and uneducated so getting them on board is always a huge, almost impossible, task.
R.I.P Sir, and thanks for bringing us the Sinclair Spectrum 128k... my first ever computer which started my love affair with gaming.
This is this first time I have seen the x1, I had known of the triwheel, which needed the top of x1, damn always ahead of time! Nice Sinclair!
I would not mind having ether the C5 or the X1.

sir clive this is great can't wait till there out

this what the world needs,clean,fun,economical and we can stay in shape.

@Azreal911
The C5 was 30 years ahead of its time and it may not be time for it yet.
Is a C5 (or an X1 for that matter) road legal in Britain?
ah - ahead of his time - RIP Sir Clive Sinclair (30 July 1940 - 16 September 2021)

Still waiting for the x1 to be launched...
I would really like one of those!
R.I.P.
Still not out :l
Somebody needs to start a kickstarter campaign for the sort of vehicle you are on about. :)

Info structure , and education ,
Semi enclosed recumbent bicycles have been around for years
Too many 'firsts' are being erroneously attributed to Sir Clive.
When can I get one in Vancouver, B.C. Canada ?
Yes, that was the whole point.
Man, if anyone has a C5 that they don't want, please contact me: I'll gladly take it (Only London Please)

Good news . Spectrum Vega is here

a c5 is, you dont even need a license! not sure about the x-1 though
people's problems are not the bike , it's there's not good enough infrastructure , and unfortunately till we have that , you won't get people out there cars .
why they have small wheels. just put normal bike wheels and make it bigger

The C5 was NEVER ahead of its time, it was a stupid, horrible idea at any time...Why not just buy an electric bike?
One word would have help the, MARKET RESEARCH, LOL
That's two words... so you're not getting hired! ;)
