Because Commodore did not include HD's as standard equipment, unlike the competition. And to upgrade your A500 to have a HD was cost prohibitive. Case certainly was never designed for one anyway. Had 2.5" drives been affordable and there was a place to install one internally without having to get a Shuffleboard and removing your internal floppy, that might have been different. But just as the argument of having certain capabilities built-in, the practically "unexpandable" A500 was doomed from the start that way. Just as the big boxes were, thanks to them being overpriced by early 90's standards
The A500 was hard to upgrade because thats not what it was designed for! You were meant to use it, and when it could no longer keep up with the modern software you meant to get an A1200. If you chose not to do that, AND still wanted to rum modern software, then you had to accept it was going to be awkward and expensive. Instead people just went:"How do i get an AGA upgrade for my A500?" Buy an A1200, thats how!
I disagree with this because, by that time, it was already too late. Software houses had already seen the writing on the wall. And ultimately, it was C= fault for not knowing how to market their system(s).
It was too late because not enough bothered to ditch their A500 and get an A1200, choose the hard drive option AT THE TIME OF PURCHASE and get a RAM upgrade later on. The users killed the potential that AGA had as much as Commodore did. Commodore was a victim of its own success, the A500 was so far ahead of its time, people expected it to be start of the art for ever!
I was an early A1200 adopter and guess what I had to do in order to add an affordable HD to my system? Purchase an ugly external box that housed a 3.5" HD w/ external power supply, with a bare naked IDE ribbon cable coming out the back of my system. Yeah, that was great. Didn't look half-assed at all (sarcasm). 2.5" drives were simply cost prohibitive. Was I being cheap? No. I was trying to be practical. By the time I ended my spending spree... I had nearly $1400 (before monitor) wrapped up in the stupid thing. Little wonder I bought 386 and then a 486 shortly after. Course now, the Windoze platform and its chinsey hardware isn't allowed in the house at all, but I digress. lol
Most A1200's I've seen had a 40 mb hard drive. The Commodore card box they came in had tick box for models with hard drive and those without, some with 60 meg, so they definately were available with hard drive from Commodore.
You didn't NEED that box, but I bet you chose to do it that way beacsue a big 3.5 inch HD was cheaper and faster-but the A1200 was never meant for big 3.5 inch drives, it was a compact all-in-one home computer, not a pro machine, thats what the A4000 was for, but A1200 users wanted pro-level machines for game console prices. this is exactly how Apple markets is computers today: hard to expand iMacs for home users with lower specs, Mac pro for everyone else. But Mac users are different; they accept that, Amiga users didn't.
I did the external tower thing as well, but that was to get a CDROM drive going, and Commodore was dead by the time CDROM was essential. CDROM at the time of Commodore was bloody expensive, so if people were too tight to ditch the A500, why would Commodore push CDROM?
