[comp.sys.mac.hypercard] Need to use IBM-PC CD-ROM Disk Data, how with Hypercard?

hlt@iapic (Harold L. Trammel) (12/01/90)

I have a CD-ROM disk intended for use with an IBM-PC program.  The
program accesses the first 100+ blocks to get the offset values
for the data to be displayed on screen.  The data is basically
acsii (I think). 

I have read that Hypercard is the best way to access CD-ROM data
but it apparently needs more than 1.2.5 is documented to have.
My Chinon CD-ROM drive has the drivers to show the single ~500MB file 
I can bring it up in MS-WORD (more than ascii shows up, hmmm).  I
cannot figure out how to go get a sector/block of the CD-ROM with
Hypercard.

Any suggestions, pointers, XCMD/XFCN locations (FTP, please) would
be greatly appreciated.  I supposedly have Hypercard 2.0 on the
way but I would like to work on this sooner than the stated ETA of
HC 2.0.

Thanks in advance,
