I made a simple block write script so I can write blocks of data to video memory to make it easier for me to find shorted/floating bit lines etc. The weird thing is, as soon as execute it and it finishes I can no longer write to video memory. For example, if reset a given PCB, see garbage on the screen and execute my scrip, writing all 0's to video memory, the screen is wiped clean. (As expected) Then if I try to write values to video mem to place a sprite at a given location ... no luck. Leave the game on.. reset the fluke... and try the same write again, and it works. So something in the script is putting the Fluke into a weird state. Any idea what could be causing this? Here's the script: SETUP TRAP ACTIVE FORCE LINE NO TRAP ACTIVE INTERRUPT NO PROGRAM MAIN DPY-# DPY-BLOCK WRITE PROGRAM EX DELAY ! Get start and end addresses DPY-START ADDRESS = /1 DPY-END ADDRESS = /2 DPY-DATA = /3 DPY-WRITING DATA# WRITE @ REG1 = REG3 WLOOP: WRITE @ REGF INC = REG3 ! DPY-WRITING $3 AT $F ! EX DELAY IF REG2 > REGF GOTO WLOOP DPY-END OF PROGRAM# !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! ! DELAY ROUTINE PROGRAM DELAY REG1=40 0: DEC REG1 IF REG1 >0 GOTO 0 Thanks for any insight, -- -Adam "Please don't judge my God by my inability to follow him" - Chris Mollins =============== www.onecircuit.com www.youtube.com/user/ajcrm125 =============== _______________________________________________ Techtoolslist mailing list Techtoolslist@flippers.com http://seven.pairlist.net/mailman/listinfo/techtoolslist FTP site is: ftp://ftp.flippers.com/TTL/TestEquipment Archive site: http://seven.pairlist.net/pipermail/techtoolslist/
