My first computer? a ZX81
Posted 29 August 2007 - 06:14 PM
The CPU was Z80 based with 8k of ROM and 1K of RAM upgradeable to 64k - I never could have more than 56k useable though.
I played with this baby so much, modifying or trying to do so, adding RAM replacing the keyboard until one day it died fried.
Today... I'm thinking - if I still had that baby... may be, with a lot of help, hey why not a yoctoXP under 56K

we assembled and soldered together computers by ourselves, and we liked it.
Yep 12 weeks to get the parts, a night to assemble and at least 10min to load from an audio tape and we liked it

Yep , you win!
Allow me to ask whether I can feel as the winner.
I already posted my old friend (1975, still working!) in this forum.
It runs on 4 KB
....but be very aware that there is a VERY FINE line between "expert" or "veteran" and "old".
Unfortunately , it seems like all three of us are walking very near this line, at least when you compare our age with that of Nuno and of a number of other members.....

No problem. If you do not know yet: expert

Mine was a c64, at least that was the one I learned basic on and wrote a few of my own programs, I was just a kid, they were games I think.
I also worked on the trs80 before that.
For many years in the 90s I had no pc though.
Over the past few years I've closed the technology gap I fell into.

I cant found oicture of my real first one. 1kb, assembler, 18 digits display, hexa keyboard.... Great luxe.
After Apple II (http://www.old-compu...r.asp?st=1&c=68) learn BASIC (with lots of GOSUB & GOTO). Yes with long, long, long K7 tape backup, and later large box externel disk 5.25 one side low density....
After this Sinclair Z81 and after Amstrad CPC with integrated tape!!!!
Later AMSTRAD again CPC with 3.25 proprietary floppy and matricial printer (it was hard to get a picture print).
Then IBM PC QWBASIC, PASCAL, 64K, 64 colors.
I lost each of one, but its true I loved to build the first one, I loved learning programming by myself (no book no internet this time)
Well I realise I am not so young.

built my own tape recorder interface into a tobacco box. Added more memory.
Later made my own including all PCBs and it was used as a battery powered data logger for medical research purposes (would not be allowed nowadays due to that famous comedy double act known as Health & Safety!).

Im down, my first computers are in the "museum" section
Anyway I loved these times. Today they are all lost in different and recurrent movings.
I think I can almost remember the Apple II basic manual, which I used to know from first to last line.
There was a sentence saying something like this:
"If you dont succeed (in programing) just rewrite and redo again, it will work one day"
Well; "some things never change"

I kept somewhere a hard disk of this time 5.25 and about 1kg for #10 Mo. Compiling a 100 lines prog was like using winbuilder now make a good coffee drink it and wash all of it.
