I have a 800XL with a 1050 drive w/U.S. Doubler installed. I made the following changes to the program to allow it to work with one drive: 840 POKE 4881,DOUBLE:X=USR(ADR(DINT$)) ^ 880 XIO 254,#1,0,0,"D1:*.*" ^^^ ^ 980 OPEN #2,WRT,0,"D1:DOS.SYS" ^ 990 CLOSE #2:END ^^^^ (The '#1' in line 880 is necessary Atari BASIC syntax). These changes should have created a double density disk with a DOS.SYS on it. Rather than using gets/puts to copy DUP.SYS, I simply went to DOS and used the 'O' option to copy it over. (I don't know if I would have been able to do this if the program actually worked). What I got was a single density disk with a DOS that still did not support double density. The U.S Doubler in my 1050 is supposedly compatible with other double density drives on the market. Any help from the Net would be most appreciated. Thanks in advance. -- Eric Sharakan, Thinking Machines Corporation, Cambridge, Ma., 02142 AT&T, et. al.: (617) 876-1111 ARPA: SHARAKAN@THINK.COM UUCP: ...!{ihnp4,seismo,...}!think!sharakan
