[net.micro.cpm] commodore128 disk format

shawn@ACC.ARPA (07/22/86)

No, I didn't buy one, I have received a call from someone who would like
to use the Commodore-128 in its CP/M Mode, and wants to use some of our KAYPRO
public domain software. First, can anyone tell me which disk formats it will
read? and second, does it emulate any specific terminal (amd3a, vt52, or ?)
would appreciate a reply either to me, shawn@acc.arpa, or to info-cpm.
Thanks in advance

	I do not know whether the new drives for the 128 support standard
	formats,  the older drives (1541) essentially contained the DOS in
	ROM inside the drive,  you were stuck with a fixed file structure.
	It also used group coding,  which does not follow standard FM and
	MFM formats (group coding is also used by Apple,  and was used by
	the VICTOR 9000 to achieve high storage densities).  The 1541 also
	uses varying rotational rates for different tracks.  In other words,
	standard drives cannot create disks for the commodore standard.
