7. TxBASIC Notes Before installing PicoDOSS into your TT8 you need to be aware of considerations that are unique to the TxBASIC environment 1 TxBASIC is the startup program that will run in your TT8 s onboard flash memory so you cannot automatically run the PicoDOS8 com mand shell nor do you normally see the TOM8 gt monitor prompt which is where you need to be to load programs 2 The TxTools communications window does not know the shortcuts that CrossCut and MotoCross use to quickly load TT8 programs so you have to perform additional steps and the program loads work at 9600 baud instead of 57600 baud and therefore take quite a bit longer 3 The order in which you install TxBASIC and PicoDOSS8 does not matter though it may change the startup behavior and what you see in your communications window which can be confusing when you re trying to follow step by step instal lation instructions Installing PicoDOS8 into your TT8 for TxBASIC Development 1 If you are running TxTOOLS and already see the TOM8 gt monitor prompt then skip the next step which forces TxBASIC to enter the TOM8 monitor 2 If instead you are seeing the TxB prompt you will need to force TxBASIC to enter the TOM8 monitor by typing a CTRL X then replying Y to the confirmation prompt You should now see the TOM8 gt monitor prompt ISTOR ents Ine 9 o g 3 GSG 2 2002 3 Type LO lt enter gt into the TxTools communica tion
