!!!Basic XL by OSS [Basic XL/BASIC_XL.png] !!ROM * [Basic XL/OSSBasicXL103.rom] latest rom image from OSS !!ATR-Image * [BASIC XL Toolkit Disk-Side A.atr] including AUTORUN maker * [BASIC XL Toolkit Disk-Side B.atr] including EXTEND (BASIC XL is enlarged with 4K additional code!) On Side B the suffix BXE is used. Don't get confused, it is Basic XL, OSS just used the suffix BXE for that disk. According to Alfred from AtariAge, there is a problem with EXTEND: Wrong is that the MOVE $0570,$C4,4 statement doesn't work. $0570 is loaded with the proper values, but the cart command doesn't actually move the four bytes. If you deposit the proper values in $C4 and $C6 then the extension works. Therefore please use: MOVE $0570,$C4,-4 to install the extension. Thank you very much Alfred, we really appreciate your help. !!Manuals * [30 Days to Understanding BASIC XL-Bill Wilkinson and Diane Goldstein.pdf] 180 pages, OCR, tera thanks to low.blow from AtariAge, he will never be forgotten! * [OSS BASIC XL-Reference Manual-1st Edition 1983.pdf] 143 pages, OCR, tera thanks to low.blow from AtariAge, he will never be forgotten! * [Basic XL/BASIC_XL_Manual.pdf] 158 pages, OCR, reprint * [OSS-The Basic XL Toolkit-Including the BASIC XL Runtime Package-Reference Manual.pdf] 42 double-pages, OCR !!Source Code for OSS Basic XL version 1.02 from February 5th, 1985: * [BASICXL102.zip] ; thank you so much for your help in this bob1200xl from AtariAge, that is such a great contribution, we really appreciate your help in that case.
