UNIXcoffee928 Posted February 12, 2015 Share Posted February 12, 2015 (edited) I have added Bit3 Emulation to Atari800. That's great news! Which version, 3.1.0? Can you provide a link to the documentation for the feature? Does it fully support everything in the manual, including changing the contents of the font EPROM? Can it open a secondary virtual 80 column screen? (You can have a 40 column and an 80 Column running simultaneously, with the hardware, as an configuration option, with two physical screens, where the 80 column card displays different information than the 40 column screen.). Thanks! Edited February 12, 2015 by UNIXcoffee928 Quote Link to comment Share on other sites More sharing options...
perry_m Posted February 12, 2015 Share Posted February 12, 2015 It's in CVS. Only one screen can be shown at once. It does support software switching and manual switching (you can use alt-shift-x to switch.) The font rom is loaded from software so it could be modified. What is described in the manual seems to work. I do not have much to test it with. The bit3.com dos xl program worked. Quote Link to comment Share on other sites More sharing options...

peteym5 Posted January 4, 2019 Share Posted January 4, 2019 Any screen shots of what the display looks like? Quote Link to comment Share on other sites More sharing options...
Curt Vendel Posted February 19, 2019 Share Posted February 19, 2019 The 9007 was used in the MIO 80 column card. Bob Also on the Austin Franklin 80 board 1 Quote Link to comment Share on other sites More sharing options...
Curt Vendel Posted February 19, 2019 Share Posted February 19, 2019 That's a nice 8021 based design, for sure. It is definitely a simpler design to manage on a card that size, than, say, a 6845 based design. Why both the 8021 and the 6545... the 6545 should be able to work on its own without the 8021, its just an attributes chip, so is it just producing the blinking cursor and maybe inversed video? Just curious. Quote Link to comment Share on other sites More sharing options...
+slx Posted February 20, 2019 Share Posted February 20, 2019 Interesting. I now own board with serial 312437.Wonder if they started with 310000, otherwise one would expect to find some of the other 312436 in practically any old 800. It's not a prime either, briefly thought they might have used primes as serials to arrive at such high numbers. 1 Quote Link to comment Share on other sites More sharing options...

It's not a prime either, briefly thought they might have used primes as serials to arrive at such high numbers. I would definitely agree. I could believe their were perhaps 2500 of these made, certainly not 31,000 on top of that. 1 Quote Link to comment Share on other sites More sharing options...

+DrVenkman Posted March 16, 2019 Share Posted March 16, 2019 I was about a 1/4 of a beer from hitting the But It Now button - I've got an 800 that already has a 32K board in one of the slots, leaving the third slot free. 1 Quote Link to comment Share on other sites More sharing options...
