Brentarian Posted August 4, 2017 Share Posted August 4, 2017 I found this 8.5"x11" plastic reference sheet that I used in my early Atari days. It was at the bottom of a box at my parent's house. I'm going back this weekend and hoping there are other Atari items I forgot to take with me 25 years ago! 12 Quote Link to comment Share on other sites More sharing options...
Savetz Posted November 6, 2017 Share Posted November 6, 2017 (edited) I made a nice 600 DPI scan of this reference card. https://archive.org/details/ProgrammersAidForAtariComputers [fixed URL] I can find nothing about M-WD, Inc., the publisher of the card. That's a terrible name for a company for searchability. Kevin Edited November 6, 2017 by Savetz 3 Quote Link to comment Share on other sites More sharing options...

kenjennings Posted November 6, 2017 Share Posted November 6, 2017 (edited) What do you think the sheet means by "Free RAM in Page 0" in BASIC v Assembler? (Blue page) Yes, I understand the BASIC cart using much of the second half of page 0 for itself. I thought in Assembly pretty much everything in the second half of page 0 from $80 to $FF was free, but the sheet says it starts at $B0.

(Blue page) Yes, I understand the BASIC cart using much of the second half of page 0 for itself. I thought in Assembly pretty much everything in the second half of page 0 from $80 to $FF was free, but the sheet says it starts at $B0. It is written "Assembler" not assembly. I am not a programmer, but i know for sure that, the debugger part for MAC/65 (DDT) is using RAM from $80 to $AF. Quote: "The DDT manual gives more information on this subject, but as a general guide you must avoid locations $80 through $AF (in zero page) and the memory location located within the bounds displayed by the SIZE command" Page 13, Section 2.5 _DDT Mac-65 with DDT manual Rev 1.2 madi 1 Quote Link to comment Share on other sites More sharing options...

+David_P Posted November 7, 2017 Share Posted November 7, 2017 ON a semi-related note: Years ago, I had copies of a one-page table from ANTIC (I think), with all the ATASCII codes in decimal, hex, ATASCII representation, and the 6502 Opcode that they represent. It got lost several moves ago; anyone able to steer me to a copy? Thanks. Quote Link to comment Share on other sites More sharing options...

+MrFish Posted November 7, 2017 Share Posted November 7, 2017 Here's another version of the Analog Pocket Ref that was done. I'm considering doing my own version too. 2 Quote Link to comment Share on other sites More sharing options...
+David_P Posted November 8, 2017 Share Posted November 8, 2017 Found the Antic version. It fits nicely on a single 8 1/2 x 11 page. http://www.atarimagazines.com/v3n9/OP_CODE_FINDER.html 2 Quote Link to comment Share on other sites More sharing options...
