Well my first computer (1981!) was (I still have it) a Commodore VC-20 (3583 Bytes RAM) I wrote some small BASIC games on it. Later I bought an 16MB Memory extension card for about 200€
@-)
Amiga 500, Amos Basic and Amiga E language 
Doing my sister’s university homework on Python (nice app called PyScripter), if you dont count me and my dad messing around in some ancient program (I wasn’t in control then, I was about 5-6). I think it might have been delphi…
A Sharp programmable calculator with 128 bytes in 1975, and I somehow fitted Mastermind onto it
My first was one of (can’t remember which), I also may have been mucking about on the mainframes my dad looked after at that time as well.

or
Dick Smith VZ200 http://www.old-computers.com/museum/computer.asp?st=1&c=979 which was an antipodian spectrum ish machine.
I went from there through Vic-20, BBC Micro, IBM XT & AT clones…
A worthy mention is the luggable Sanyo MBC 775 XT which had 2!! floppy drives http://www.1000bit.it/scheda.asp?id=1154
Commodore PET and then the ZX81 (Yup, I’m THAT old!) 
I am pretty young so my first technical thing was a HP computer with windows XP. I do not remember the computer specs but it was stationary.
Tandy TRS80, with 4ko (yes, taht much) RAM, and a tape recorder. wiiiiii…iiiiiii…iiiiiii…
My first computer (that I owned) was an iPad… :-"
Texas Instruments SR 56 programmable calculator. It has a 100 step program memory. I still have it and it still works. After that it was an Apple II with a tape recorder to save the program.
Windows 7 Home Premium 32-bit laptop, with 3GB RAM. XML on a website called Playcrafter. I still use that laptop, and all of my projects are on it. :))
Haha you can clearly see whos been sticking around for a while working with computers, while other newcomers (like me) get really nice gear as first machine.
Texas Ti-80 calculator I believe it was in the mid 90’s. I use to spend class writing little apps to make the homework easier then distribute it amoung the class. Everyone started aceing the classes and the teacher caught me. Gave me a huge congrats and told me if I know it well enought to write the apps it was fine but I was not allowed to share them. Also made text based games and graphical games using the graphing features.
When I started working, the company I worked for all old dos applications for their billing software. I decided to learn windows programming in c/c++. I re wrote their software thats still used to this day.
KayPro 2 (using Basic) when I was really young, the TI-?? calculator in high school (also Basic), then GameBoy Color on imported korean bootleg hardware. Then I got a job making GBA games
TI 99/4 (not the 99/4A – that came later) in 1979. And I was no kid when I did it.
Yup, I’m ancient.

A hackintosh made completely from parts on Freecycle.
IBM 7094 Feb,1963 first computer class at University of Illinois, Urbana, Illinois, USA
They taught us assembly language then FORTRAN. Doing matrix multiplication in ASM on a machine with one’s complement subtractive index registers taught us how the machine really worked. Then we did the same problem in FORTRAN! SO MUCH EASIER!
First paid programming job Oct,1963 on a CDC 1604.
The newbies learning programing using CODEA and Lua on an iPad will not have as much stuff to unlearn and will be much more productive much quicker on a system that I hope will be around as long as they are.
I don’t know if this counts, but going back before my programmable calculator, I was programming on an IBM 402 accounting maching and other data processing equipment. Here is a link showing the control panel for the 402 without wires, and then one with wires to control what it did. Each hole had a specific function, so depending on where you put a wire you could do calculations and print out reports, http://www.columbia.edu/cu/computinghistory/plugboard.html
It was an Atari 400 and it was basic. There was this cool 3rd party language called Action Compiler I mesed around with for a bit.
Amstrad CPC 6128 (white & green screen) , 1985.
I was trying to make a game with the BASIC language manual , O:-)
