How to access other floppy drives from CP/M

Post by Deoxys357 »

I was wondering if anyone knows how to access the other 2 floppy drives ("Extra Floppy" and "Altair DOS") from CP/M. When I type "b:" I get a bad sector.

Those disks are for use with Altair-written software only they aren't in a format that CP/M can read. The Altair DOS disk must be the boot disk if used. You can then create blank disks in Altair format.

Which disk are you calling Extra Floppy? I don't see one in the list of disks that come with the 8800 emulator:

00001) DISK01.DSK: CP/M (63k)
00010) DISK02.DSK: ALTAIR DOS 1.0
00011) DISK03.DSK: ALTAIR Disk Basic
00100) DISK04.DSK: ALTAIR Disk Basic programs
00101) DISK05.DSK: Games (CP/M programs)
00110) DISK06.DSK: SuperCalc II (CP/M program)
00111) DISK07.DSK: WordStar (CP/M program)
01000) DISK08.DSK: Zork (CP/M game)
01001) DISK09.DSK: Time Sharing Basic V1.1
01010) DISK0A.DSK: Time Sharing Basic V2
01011) DISK0B.DSK: Time Sharing Basic V2 programs
01100) DISK0C.DSK: Altair Mini-Disk Basic
01101) DISK0D.DSK: Altair Mini-Disk Basic programs
01110) DISK0E.DSK: Altair Mini-Disk DOS
01111) DISK0F.DSK: Altair Mini-Disk DOS programs
10000) DISK10.DSK: Dazzler programs (boots CP/M)
10001) DISK11.DSK: VDM-1 programs (boots CP/M)
10010) DISK12.DSK: IMP modem executive (CP/M)
10011) DISK13.DSK: CP/M 3.0 disk 1 (boot)
10100) DISK14.DSK: CP/M 3.0 disk 2 (utilities)
10101) DISK15.DSK: Felix animation system for Dazzler
10110) DISK16.DSK: CP/M 2.2 MITS+Tarbell

As shipped, the Altair Clone has Altair DOS on the 2nd drive and Altair Disk BASIC on the third drive. These are not compatible with CP/M. You can certainly load CP/M disk images into the 2nd and 3rd drives if you want all three drives to be usable under CP/M.

Not that the list of disk images Tom provided is for the Altair Duino, not the Altair Clone. For the Altair Clone, you upload any disk images you want into the Altair drives from your PC.

Quite correct. I use the same disk images on the Clone, the AltairDuino and the Windows Altair32 emulator. Very handy, indeed!
