  @2:25 What does it mean "only one bitplane is active at a time?". What do we mean by the word "active"? My guess: Only one bitplane can be read/written by the host at a given time.

• 
  @root424 күн бұрын

  Yes, exactly. You can write to more than one bitplane at once, but not arbitrary values. However this is quite efficient to do fast screen clearing, as up to four pixels (f the same color) can be written at once.

  I never understood why Mode X was set up using mode 13h as the base. In my program, I used the mode 12h 640x480x16 as a base of mode X. In addition to the palette registers, only 3 other registers needed to be modified and minimal modification to the CRTC. - Has been very compatible, the mode and the program run fine on bare metal DOS boot on 6th generation Intel.

• 
  @root424 күн бұрын

  Interesting idea. My guess is that it was assumed that mode 13h has very similar timings and this was more crucial than the bitplanes. But maybe even that is wrong as 640x480 has the same timings as 320x240 except for the pixel clock.

  The emu68 1.0 release has come a long way. When I built my PiStorm 3 years ago, I quickly became disappointed because so many of my favorite games had issues with it. Out of frustration, I then purchased an ACA500+. One of my best buys ever. Even though it ran fine at 42MHz,, shortly after I added an ACA1221 just to have the 020 for the games that specifically supported it (like Ambermoon). Two years ago I digged out the PiStorm again for trying the experimental emu68, and it felt already a lot more compatible than the linux based emulator right from the start. And yesterday, I tried the 1.0 release of emu68 and everything I throw at it just works perfectly. All the compatibility issues I had seem to be gone. Absolutely amazing. The only one thing that PiStorm/emu68 is really missing out on is a way to easily switch the emu68 configuration. Right now, you'd have to prepare and swap SD cards with different configs, which kind of sucks. Especially if you have no LazarusStorm adapter. The ACA500+ is -a lot- more versatile in that regard.

• 
  @root426 күн бұрын

  I would still recommend the ACA500+ for people who want a „plug and play“ solution. It really „just works“. And the optional A1200 accelerators can take it even further. For everyone who is technically inclined and likes to dabble in the configuration the PiStorm or Lazarustorm is a great option. We currently use the ACA500+ exclusively as our daily driver. Makes playing older adventures from harddisk a breeze. And the stealth mode is awesome for compatibility.

  Nice job on the 500! My first Amiga was a 500 back in 1989. I still have it in much butchered shape as I modified the case to fit a standard floppy drive. That camera in the brown case reminds me of my first 35mm camera when I was a kid in the '70s. It was a coupled rangefinder Balda with a Baldanar lens given to me by my grandfather. I still have it kicking around here somewhere, but it hasn't worked in nearly 50 years!

  Having different coloured wires would have been really helpful to both you and the viewers! Also, I note that the modification kit you used did not have a "75R" resistor (?). Mine had this, in addition to the 2.2k and 3.3k resistors, along with the transistor. Might this explain the imperfect video signal? I got my kit on Ali Express.

• 
  @root42Ай бұрын

  The video is literally 5 years old today. It was an eaaarly video. :) I didn’t buy the kit, but used things I already had. I thought about revisiting this mod, but have been using the Atari Jr much more in the past years, using the tfw8b deluxe composite mod instead. So maybe there IS a mod that will result in better video quality. The 75Ohm resistor might be for proper termination.

  I was playing around with developing a new SD card solution that interfaces to one of the VIAs. It is perfect for drives with broken heads. When using it you can get the real heads to move and the real disk to spin but the data comes from the SD card. This way it feels like you are fully using the original drive. Externally you could not tell if the data is coming from the actual disk or the SD card.

  16:49 Twisting the stepper motor more than the distance covered by a siingle step (i.e. a full half-track) is pointless as the next headbump will reset the adjustment. You need to look at and adjust the track-0 head stop instead.
