    The Apple ][ Plus has a built in joystick port, it's a dip socket in the upper right of the motherboard. There were joysticks that plug directly into this socket, and adapters that convert it to the 9 pin connector used on the later models.

    That's pretty much the Apple ][ setup we had. It was strictly forbidden in our house to put the disks on top of the monitor though!! Glad you addressed this, made me smile.

    Crazy that you can have a system fast enough to bitbang HDMI just as an output for a system with single digit MHz clock.

      The processor on that HDMI output board is fast enough to emulate a Mac 128K and bitbang VGA at the same time.

    So, there isn't actually a card that you plug into the expansion ports to add a joystick to the II or II+, there is a 16 pin DIP socket on the motherboard labelled GAME I/O that the joystick plugs into. You can either try to track down one of the DIP16 type joysticks or buy a 9-pin apple joystick and get a DB9 to DIP16 joystick adapter.

    The fundamental difference between an Apple 2 and an Apple 2+ is Applesoft BASIC in ROM as well as the autostart F8 ROM which causes the machine to auto start/boot disk type devices.
    Regarding Videx 80 column setting. There was a card made by Videx that gave the 2+ the ability to do 80x24 text only video. The card had a totally separate video cont roller chip and RAM, basically it was a terminal (think VT-52) on a card. You would install the board in slot 3 and activate it with a PR#3. Since the card produced it's own video signal you would either manually switch the cable going into your monitor from the connector on the back of the Apple to the one from the Videx card or there was a little board that would wedge in between one of the chips on the motherboard that would do the video signal switching automatically. The board was called the "soft switch".

    Amen with the scanline talk! I'm a firm believer that if you do want to add fake scanlines, 50% black is totally wrong. MAYBE you can get away with 1/4th by scaling the game 4x, but that's still not exactly right. It just sometimes feels like all these filters were made by people who haven't actually seen a CRT, or haven't seen one in decades. They weren't remotely that crappy, the filters are lying to you!

    Dang, I will admit that when the Pico first came out, the RP2040 seemed a bit underwhelming compared to Arduinos/ATMegas, but whoever designed PIO and made it fast enough to output video signals was a genius! The firmware says it can do 720x480@60Hz, and the fact that you can bitbang that high of a resolution out of the PIOs makes the Pico/RP2040 one of the finest retro-accessories ever. (Also shoutout to ZuluSCSI which does SCSI on a Pico)

    You would pick the AppleII. The Plus is the excat dame machine with just some updated ROMs. The Plus has basic in the ROM and can autostart from disks, ehoch the og didn't.
    The IIe is quite a bit different beast, hardware wise.

    Not to mention, short of physical damage, low-density floppies are >really hard< to erase "accidentally". Nobody freaks that there are magnetic motors in the drives directly adjacent to the disk, for example. No way are SSDs going to sit in an attic for 50 years and still boot first try...

    If my memory serves me correctly the Apple 2 plus does not need a game controller card because the controllers plug directly into the motherboard. It's a strange connector that looks like a chip

    Fake scan lines are hard to get right. The only implementation I’ve ever liked is how the latest RetroTink renders scan lines. They implement bloom and allow for a lot of customization so you can dial it in just how you like. Personally though, I only ever use it if I’m up scaling an old game console to a VGA CRT monitor. That way I can have a cheap high quality CRT for old school gaming without shilling out for a PVM

  • @Vaionko

    It's interesting that the cursor seems to blink slower on the HDMI than the composite output. I guess it makes sens sincr the card is essentially a whole new video chip

    • @MacRetroFly-ef8cc
      @MacRetroFly-ef8cc ชั่วโมงที่ผ่านมา

      Yes, the Apple II generates the flashing frequency using a separate NE555 timer circuit, so each machine has a slightly different blinking frequency. And the frequency is also affected by degraded capacitors. (That was actually different with the newer IIe design, which generated the flashing frequency based on the video clock, so used a precise timing source).

  • @phipli
    @phipli 2 ชั่วโมงที่ผ่านมา

    Can you make a controller with a couple of 555s to convert an analogue joystick into a timing signal and then use a 6522 or something... There must be a standard design on that classic solution.

    • @CharlesOttman
      @CharlesOttman 2 ชั่วโมงที่ผ่านมา +3

      The 9 pin is on the //e, //c, or IIgs. The 2+ has a 16 pin socket on the motherboard. Adapters were/are available to convert that 16 pin connector into a 9 pin style which is just so much easier to deal with.

    • @larryk731
      @larryk731 2 ชั่วโมงที่ผ่านมา

      The socket for a joystick is around the right rear part of the motherboard- the joystick connectors are fragile - be careful. Search for a joystick that automatically centers (they were common in the 80s) but in 2024 settle for any apple 2+ joystick that survives

    I'm already impressed, but also curious about its compatibility with the IIc or IIGS. Still, glad to see this, modernizing equipment here is great, and being able to stay on the analog screen is nice for keeping it indiscernible from any other A2.

    • @CharlesOttman
      @CharlesOttman 2 ชั่วโมงที่ผ่านมา +2

      Totally incompatible with the //c since the //c has no slots. It's my understanding that it'll work in a IIgs but only for the old video modes, nothing specific to the IIgs, no 320x200 or 640x200 super hires stuff.

      It's actually a "PICO", not a "Pi". Pico is much smaller, a tiny and very efficient embedded controller, which is NOT running Linux etc, but meant for bare metal applications. But both are designed by the same company - which, confusingly, also calls itself "Raspberry Pi (ltd)".

    Normally I don't have any issues with your presentation, but there are several repugnant youtubers who I "affectionately" call them "talking hands" and down vote their videos because it is so worthless to watch. I can understand 10 seconds max, but using it more than this is vile to watch. I don't care if you were to run b roll and talk over, but to keep moving the hands as if they are talking, it is disgusting to watch. As the talking hands portion is an exception to your usual video presentation I did not downvote.
    Otherwise, interesting how an otherwise worthless piece of technology (the $5 board) into something that brings a vintage computer into the modern world.
