(XMODEM transfer occurs here...)
Return terminal computer to 9600 baud, then press return:
If the XMODEM transfer must be aborted, first abort the Clone transmission by
raising and releasing the left AUX switch, then stop the receive operation on
the PC end.
4. Change Floppy Description
Use this menu option to change the description of a drive’s content. This can
also be used to “eject” a floppy you’re no longer using by changing the de-
scription to “Scratch Disk” (or any similar description) to indicate the
drive is free to use. From the Altair’s perspective, a floppy disk is still
present in the drive, just consider it a blank or scratch disk.

B. PROM Menu
The PROM menu is used to insert and remove PROMs. Eight slots are provided
for PROM content. Each slot is up to 2K bytes in length. PROM content is up-
loaded from a PC in binary (.bin) or Intel Hex (.hex) format. Once uploaded,
PROM content is non-volatile. PROM content can also be disabled without actu-
ally removing the PROM so that it can later be re-enabled without having to
re-upload the content from a PC.
When the PROM Menu option is chosen from the main menu, the current content
of each PROM slot is displayed as shown below:
