Retroprogramming sux video:www.youtube.com/watch?v=X9E5CXbjlzk This is my first try to learn how to code on TRS-80 Model I. I tired of stupid EDtasm interface, so CMD has been created at SJasm+ Manuals very differ from System/80 version, if you want to try, do one: -download disk image:http://www.classic-computers.org.nz/system-80/disks-NEWDOS-2.0.htm - mount to emulator(Real80 or trs80gp:http://members.shaw.ca/gp2000/trs80gp.html), you don't need to lurk .ROMs.huh? - type "DIR 0" to view listing or "EDTASM" for launch. for EDTASM next commands available: *I100,10 (* - is a command prompt) - start to numerate program from 100 number with step 1, hit Esc(Break for TRS-80) to stop D100:101 - delete lines from 100 to 101 W D=LIST/MAC:0 - writes listing on drive 0 with LIST.MAC L D=LIST/MAC:0 - opens file LIST.MAC from drive 0 to assemble listing type A/WE object file specification is PROG/CMD:0 TRS32 allow to copy/paste text, if you do not want to type code what's it. about sjasm+ source - I still not sure about program format.
