HAS YOUR COMPUTING AFFECTED YOU"?

One ofthe more interesting threads (that's the term appliedto a series ofonline

messages concerning a specific subject) that I've .seen lately in the Commodore

Usenetgroup(comp.sys.cbm)isonethatasksthequestion, "Whatmadeyouwant

a Commodore 6J/I2Mcomputer?" The responses to thishave been in some cases

typical, but some are rather interesting. Seein the question and the responses

there naturally made mepause to reflect on why (and how) I got involved with

Commodore computers, and even more generally with computers themselves.

Having comefrom a technical background where 1 regularly worked with,

designedandrepairedelectronicdevices, the introduction oflowercostcomputers

wasnaturally ofgreat interest to me. Myown knowledge ofbow they workedfrom

a hardware standpoint was, while incomplete, at least generally sound. Hut my

curiosity about how software andprogramming couldinstruct a limited amount

of hardware to do so many things is what probably drove me to buy my first

computer 'kit'.

I recall the arrival ofmy new purchase being met with much excitement and

anticipation. I'd already begun to play around a little with a single-board

computer(SBC) we hadat the office, butit was extremely limited. Unfortunately,

so too were my own funds, and mv 'kit' consisted oflittle more than an S0H5-

based S-IOO motherboard with very little RAM. and a small OS. But this was a

fullyexpandablesystem, capable accessing awhopping64KofRAM once Icould

affordthat much. Andunlike the SRCfrom theoffice whichhad onlya hexkeypad

andfour 7-segment display modules, my new machine had a keyboard interface

and a CRT text display controller on-board.

Afew hoursofsoldering later, I didhaven working computer, though I had to

take it to afellow engineer's bouse to test it out with his keyboard and monitor.

Hut there is where I caught sight ofan amazing box. owned by the engineer's

son—he called it a Commodore PET. While the display was monochrome, it

actually had graphics, and could do some mighty amazing things.

Ii wasn't long afterwards that Commodore announced the VIC-20. an

inexpensive computerwith color, and Ihadto have one. I abandoned the idea of

expanding that S-100machine Iwhich would have cost over $11100 lo complete).

I.savedandwaitedforprices to drop, and before long I was learning toprogram

on one ofthe hottest new consumer devices around. The natural migration to a

Commodore 64 came a year or so after its release, and by then I had that firm

grasp ofthe concept ofsoftware I'd been looking for.

Looking back. I'd have never guessed that my initial desire to learn about

software would have brought me lo where I am today. Editor ofone ofthe last

bastions ofsupportforthe C-()4. Hut it makes me curious lo know, how hasyour

own involvement with computers affected you?
