Load with screen enabled, but cleaner output?

[modeler]

I wanted to make a tape loader with the screen enabled, so I removed the two lines from gyrospeed-header.asm:

SetupAndWaitForTurboPilot:
lda #$07
sta $01 // Start the datasette motor
//lda #$1b
//sta $d011 // Disable the screen

This results in the below:

It's close to what I want, but I have been trying to find a way to suppress the READY. prompt at the end. I just wanted to to show "LOADING" with no further output from BASIC.

Back in the day, I used to end short routines with JMP $A483 rather than RTS to return to BASIC without printing READY.

In gyrospeed-boot.asm, I see there is already an indirect jump to this routine (default vector being $A483 anyway I undersand):

JumpToBasicIdle: jmp ($0302)

So the prompt must be triggered elsewhere? Any help would be much appreciated, this is a very nit-picky issue I know, but it would be nice to figure it out as it's been bugging me for ages.

Thanks!
