    I was a Commodore PET / VIC20 / 64 / 128 user, but I'll admit that those Apple II drives were SNOT FAST.

    POP QUIZ if you were at the monitor prompt (*), what would you type instead to get the disk going?

    >>19934630

    Didn't you guys have some cartridge or something you had to plug in before you'd get acceptable disk performance?

    Apple IIs used to fill me with dread: What do you mean you need to boot from a disk? You mean there's no ROM that will take me automatically to BASIC when I power up? Eeeck!

    That's because commie 1541 drives were basically "round tape" and were the worst drives on the fucking market.

    In grade school, we had a big lab full of Apple IIs. The power all ran through a master switch in the room. When you flipped the switch, they'd make all those wonderful booting noises in unison. It sounded awesome.

    Uh, there was. Just hit Reset after you power up and you're instantly at a BASIC prompt. What the fuck dude.

    Yeah, they were called FastLoader cartridges, and they turned disk access from serial to parallel. I never used them because:
    - The advertising for these cartridges never really explained how they were supposed to work
    - There were stories that certain copy protected games would fail if you used them because they threw off the drive's timing
    - You had to open your hardware to make the change and my family was too poor to get a new computer if I ruined ours

    BZZZZZT nope

    (hint: the only reason you type PR#6 at the Basic prompt is because the disk drive controller is in slot 6)

    I don't remember this. BASIC was loaded from disk.

    You could switch between the monitor and BASIC. 'CALL -151' at the BASIC prompt would drop you into the monitor; Ctrl-B at the monitor prompt would put you back into BASIC.

    No, *DOS* was loaded from disk. *BASIC* was baked into ROM. Applesoft BASIC for II+ and higher, Integer BASIC for original II.

    Back in the day, these were super high tech. I remember thinking "Wow! How can people know where all those traces go?"

    Now you can send out your PCB design files to any number of rapid prototyping houses and make your own for a few hundred bucks. (Now if only I had a project worth doing! I was thinking of creating my own CP/M machine using some Z80 variant, but really, other than getting it to boot, I'd have no use for it and it would just gather dust.)

    Shit, I had to know that recently. See the transistor and resistor I have circled here? That's the "color killer" which strips out color from text so you see as pure white-on-black, instead of white-with-bleeding-colors-on-black. It wasn't working anymore, so I bopped on down to Radio Shack, picked up the components (I couldn't believe Radio Shack even still sold this shit), soldered them in, and bam, good as new!
