  1. Time is an illusion. Lunchtime doubly so. - Douglas Adams
  2. A friend of mine in high school wrote a bootable loader that ran out of the stack. There were very few games that it couldn't load - it's been over three decades, but as far as I can remember, it only choked on one or two titles. He called it the Batillac, after Batfink's car. It only worked on Atari DOS formatted disks, not SpartaDOS, but it had the capability to read a new directory by hitting space (so you could launch games from another disk) as well as writing itself onto another floppy. IIRC, I think it took something like 7 sectors.
  3. OT: Every time I see this thread title, this is what pops into my head:
  4. I never realized just how much smaller the 400's keyboard was, but this pic really shows the difference!
  5. Ooooh, Algebra! W=L and R=W, therefore, R=L. Exactly what one would expect on a non-stereo, 1979 mono system! 😁
  6. I replied in your other thread. Here is my reply, copied from it: That looks like your joystick thinks that it is always pointing down. Does it do this with no joystick plugged in? The down pin on the joystick port is pin 2, which is connected to pin 3 on the PIA chip. The PIA is seeing this pin as grounded. If you pull out the PIA chip, and test pin 3 of the socket without the PIA plugged in, is it connected to ground? If so, there is some short to ground somewhere on your board. If pin 3 of the PIA socket is not grounded, then the issue is with the PIA chip itself, as it thinks it is grounded. One test you could do is to bend up pin 3 of the PIA before you put the chip back into the socket. That way, it is completely disconnected to anything. Then, if you run your joystick test, does it still show 13? If so, then it is definitely a bad PIA. If it shows 15, then you could use a wire to ground the pin that is sticking out and then it should show 13. If so, then your PIA chip works properly (at least for this pin).

  8. What does the built-in self-test report for ROM & RAM?
  9. Set your drive to D1, but leave it off. After booting up with RespeQt at D1, clear slot D1 on it and power up your drive to test it as D1.
  10. A Sticker! Doh! Sometimes we get so enthralled with the new technology that we forget about the older, simpler solutions!
  11. Counterpoint: The 800 was designed for upgrades with the "personality board" in a user-accessible slot, as well as the RAM. The CPU board is also in a slot, though not directly accessible to the user. Early advertisements even called out this expandability as a great feature to ensure that the system never went out of date.
  12. That would be awesome, and is very generous of you. I still would like to source a working adapter so that I can go between the Incognito & the Side3 on my 320XE, but this would help me to verify that my Incognito is fully functional and let me actually get back to some 8-bit development productivity (it's been 9 months since I've worked on the game I started writing to use the driving controller). I have also been putting off doing the light-guide ATR swap button mod until I am sure that the Incognito works right.
  13. What about doing the letters as cutouts in the back piece, exposing the back of the PCB? You couldn't do the overlapped checkmark, but could have it as SYS✔️. Or, to keep the overlap, the checkmark could be done as a dotted outline or have breaks in the outline 'stencil-style'.
  14. So it does seem like it is one of the "fake" adapters that @lotharek shows in the above video. I was able to take a microSD card that did not work in the adapter, put it in a micro-to-full-size SD card adapter and into a Side3, and then I was able to run FDISK on it and set up a bunch of partitions which could then be read by my 320XE with the Side3 plugged into it. When I moved the properly configured microSD card back into the CF adapter and put it back into the Incognito, I could not see the directories and I could not see it in FDISK. So, case closed...? I would still like to be able to get a properly working SD-to-CF adapter, though, as 1) I have a lot of SD cards, 2) my laptop has an SD card slot, and 3) I don't have a CF reader for my laptop.
  15. Nice! The grip ridges are a nice touch, too!
