I want to transfer files from the 8" disks of a CPT 7800 word
processor system to a VAX 750.  I was planning to do this via
my CP/M system since I have a program which will write VAX
readable files from CP/M and I am sufficiently familiar with my
BIOS to create the disk tables needed to read foreign format disks.
However, there is one small stumbling block.  I don't have
sufficient information about the CPT format to accomplish this.
My controller seems to think that it is formatted in 256 byte
sectors, but I have not been able to log a CPT disk on to look
at it with DU.

Does anyone have the information I need to solve this problem or
to convince me that it is unsolvable?  Alternatively, does any one
know how to go from the CPT to the VAX (and vice versa) directly?

Thanks,
