The thread is too long now to read every single line but it looks like most of you started with one of the Sinclair offerings. Shows just how much Mr Clive has affected our lives, where is he now?
It's not that long. A quick scan does not support your assertion. Probably just as well, the quality of Clive's products left a lot to be desired. Best "built to a price" computer kit until the Pi Zero, though.
I (pre) ordered a ZX80 but it was going to take far too long than an impatient twenty-ger was prepared to wait so I cancelled it and got the OHIO Superboard 2 (Challenger II P) instead, I must have spent more hours programming than I spent playing Space invaders later..

Programing was a slim version of Basic, then Machine code could be used by poking data in to the Memory locations one at a time, there was no way back so any mistakes meant starting from the beginning... Grrr..

It still lives in my loft and worked at last outing a few years ago, much modified by now of course.
After learning to program on the local college (Merton Tech) mainframe (they allowed access to local schools), I bough a UK101 kit (Ohio Superboard 2, IIIRC) SBC around 1980. Luxury kit with 2K "Monitor" (OS), 8K Basic in ROM, 8K static RAM and 1K video memory. Program storage on cassette, 6502 processor running at 1MHz. Still got it somewhere.... though now with 32K dynamic RAM (again IIRC), 2K video (48 char x 32 lines), and RS232 with proper +/-5V switching and multiple baud rates. I'm not sure I'd risk switching it on -- chunky electrolytics now almost 40 years old :shock:

PS the kit cost £219 +vat!

Pretty much all of the above modifications to mine too, add on PCB for memory, cassette baud rate doubled and video doubled, then rewrote some of the OS to clear it all at startup.

I put a speech synthesizer PCB on it too and bought a Colour graphics PCB but never got round to fitting that.. one day I might. :lol:

A Commodore Vic-20, saved up my paper round money for 15 months and bought it in 1982. Then spent as much on an afron interface, which was a case the Vic-20 sat in and had a built in power supply and 8 slots for cartridges, was able then to get it from a 3.5k machine to 59.5k. did my programming O'level on a Commodore PET and my Vic-20..

Went on to having a C64, Amiga, Amiga 128, Spectrum 128, IBM AT, IBM XT, Pentium 2 etc etc, gone are the heady days of working out fuel / mileage consumption for a fleet of vehicles using lotus 123 running on an AT PC (circa 1986).

As a newbie to the Raspberry Pi and as I hit 50 this year I decided that the Pi would be a great place to get back into coding and to have a cost effective tool that I should not be able to break.

I have setup a Pi ZeroW running OSMC as a media centre with a terabyte drive all powered and LED lit from a USB Hub, case still to be completed. I also need to figure how to get the stuff onto the drive without removing it and plugging into my PC.

Am busy working my way through the CamJam EduKit 1, and am attempting to write code that would output what I type directly as morse code ( my thoughts are that as i hit return the pi would then output that line typed) still a work in progress. Any ideas anyone?

I worked For DEC field service In Canada starting in 1970. Initially in Toronto then later in Ottawa. I serviced PDP 8 and 8i in the Toronto area. In Ottawa I did regional support for all of Canada for these products. I got to visit all of Canada. I later worked in manufacturing for DEC in Puerto Rico as QC supervisor. I Spoke Spanish from previous Job. This was for two Years. This was where DEC was building there PC compatible computer. Then back to Toronto as supervisor for the LCG ie Dec 10/20 family out of Toronto. Next I was Manager for Field Service Training in Canada till I retired. I still own a Micro Vax and a PRO 380. It is a shame because bad decisions by upper managers the PRO family based on the PDP 11 could have been the Personal Computer "PC" rather them the Intel based computer and maybe DEC would exist today. DEC to Compaq to HP is what happened to the company. The Company had good products but Ken Olson believed that time-share was the way to go and not Personal Computers and DEC Personal Computer was not completely compatible to the IBM PC. Software written for the PC had to be modified to run on the DEC PC. Companies would buy one or two large computers but many of hundreds of the PC's

mine was the Apple 2. I remember there was a pinball game, a space station game, a Where in the world is carden sandiego game. I got some good childhood memories of that thing.

Mine was a Commodore 128, though i generally ran it is 64 mode. I remember my first look at a 3D game, Super Huey 2, and was amazed at the quality of the graphics and sound. but compared to current computer offerings, what used to pass as quality 3D, now is laughable. :lol:

I think i may even have it still kicking around somewhere, though the floppy drive is toast. i think the PSU may be toast too.

A Sharp MZ80K in about 1981 when I was at college. Not very good for games, as it had very blocky graphics and a black & white monitor, although I wasn't really interested in games for it anyway. It had the monitor, keyboard & tape player inbuilt in the steel case, very much a Japanese version of a Commodore PET, although with a Z80 instead of a 6502.

Came in handy for college Z80 programming and hardware courses though - easy to hack around the discrete logic chips on the motherboard.

The first machine I actually used was an ICL 2904 mainframe via a remote teletype and paper tape from school.

The first computer I owned I had to build myself in 1982 or so. It was a small single board computer using a Motorola 6809 processor. It had a 2716 EPROM and about 2K orso of RAM. The user interface was a hex keypad and 6 digit seven segment display.

It was a circuit published in some magazine, Wireless World or such. Sadly I can't find any info on it or links now.

My very first computer is a Asus 14inch, I spent most of my university life with it, it ran very cool and powerful. I'm still using it now just in case my Macbook gets problem :)).

VIC-20 with 256kB of RAM, some 128MB of EPROM, floppy, teletype, modem, hardisk, printers, 2-crystal-rtg-spectrometer,
Another boards were Micro-Professr with Z80 and NOVA-RAM
After these I got Dragon-64 and some computers, which I buIlt from components.
During the years I have built tens of computers and written some OS and other programs.

My first computer was DEC-10
