Maybe I'm just daft, but I don't get it... so I've created the massively complex m/c routine:
DUMP 1,0 ORG 32768 LD A,6 OUT (254),A RET I then assemble this (F11) and then run SimCoupe (F9). 1. starting SimCoupe starts it without the object.mgt disk being opened. 2. so open it manually and boot1 The object binary is 15 bytes - it should only be 5 bytes based on the source above. Viewing the contents of the binary shows that it contains some leading and trailing rubbish: 32768: 0 32769: 0 32770: 5 32771: 0 32772: 1 32773: 62 <- here's LD A, 32774: 6 ... 32777: 201 32778: 0 32779: 0 What's going on? Regards, Stefan (using Windows Vista x64 just in case it matters).
