Ah right, I vaguely remember getting the 512KB memory extension back in the day. So 512k basic setup from the A500 plus the 512kb extension adding up to the total memory. I will look into those further memory upgrades, sounds like a good idea.
As for the disk drive - I checked it again. Not a single word, label or sign on it. Really odd, must have been a super shitty white label one, haha. It does not make any sound, no clicking (the search sound), no light flashing and regardless of the position of the 2 switches at the back it does not affect the drive it seems. Looks like it might simply be dead.
My goal is to get a hard drive anyway, then I assume secondary external disk drives become more or less obsolete anyway.
