  1. The 400 was this poor college student's ticket to the wonderland of 6502/ANTIC/CTIA/POKEY programming and Star Raiders gaming in 1980. The membrane keyboard was well done, with raised edges and speaker clicks which you could feel and hear. It served me well for two years until the 800 became affordable.
  2. Not true. It's not OmniView. Not true. It's about twice as fast as the OS 40 column mode, because scrolling shuffles a few display list pointers instead of shifting all the character data. Maybe try the software before you criticize it.
  3. So, when did the underscore become correct English punctuation?
  4. Yes, software 80 columns using ANTIC mode F. DT80 is the dumb terminal version for use with the ATR-8000. ACE80 is the right cart version for the 800. ACE80-XL is the left cart version for any Atari. They replace the OS E: device so they work with BASIC, DOS, etc. There are patches for the 80 columns versions of Letter Perfect and Data Perfect. The carts have switched ROM so they don't displace any RAM. They do use over 12K of RAM for display, character buffer, character set, and resident code. This old thread has details, including my first ever post to these forums:
  5. Many other good presentations there. A few commodore guys getting the history wrong. Surprise.
  6. Kay Savetz showed cool Twitter bots which run BASIC code within a tweet.
  7. If they are big square pins, then the sockets might be stretched so they might not hold regular chips very well. If it's working, why not leave it in?
  8. This weekend! http://vcfed.org/wp/festivals/vintage-computer-festival-east/
  9. HALT is used in the 130XE to determine whether ANTIC or SALLY is accessing RAM. So the switch defeats that separate ANTIC RAM access mode which the "PD" upgrade doesn't support (shame on the designer! ).
  10. I've migrated the list to Google Sheets for easier maintenance. See post #1. https://atariage.com/forums/topic/176199-calling-all-400s/ Please check your entries for accuracy, in case I made errors in transcription or copy/paste. For those of you with ??/?? dates, please try to find the 3-digit date code, either stamped in ink on a label or imprinted in the plastic case, rear underside. Please post any corrections/additions here.
  11. Sounds like the show was mostly about the ST. Around that time I was getting out of the ST hobby, which I never got as deep into as I had the 8-bits anyway. I sold my ST while it still had resale value, to help fund my newer hobby, aviation. My log book shows that, during the 3 days of the MAGIC Show, I made 4 flights in rented aircraft. The next weekend, I bought a plane.
  12. Do you remember where it was held? I don't think I went.
