FILE BROWSER
A file browser is built into the MINI PET BASIC 4.1 ROM images. This is particularly suited to use with the
SD2PET SD card disk drive.
This can be activated by pressing the NMI / MENU button on the bottom right of the keyboard.
The standard BASIC 4 ROM sets also contain the file browser as an option ROM, at 0x9000. To activate those
versions, type
SYS 36864
(or it can be easier to remember to type
SYS 9*4096
).
CONTROLS:

Up / down arrow keys – scroll through the list of files

Left /right arrow keys – scroll up or down one page of files

Return – load the select program change into the selected directory or mount the selected disk image

Clr / Home – Move up one directory, out of a disk image

S – Toggle sorting the list of files alphabetically

D – Cycle through the available drives 8,9,10,11 (if present)

Q – Quit and exit to BASIC

= – toggle font uppercase / lowercase and uppercase / graphics
When a program is selected, the Mini PET will be reset and the program automatically loaded and run.
Alternatively, you can browser to the appropriate folder and / or disk image and then exit to BASIC and load
the program as normal.
When you return to the file browser, the previously selected folder will be preserved or disk image will still be
mounted, to save having to browser back there again.
