External PCM indicates that the sound is taken from the 'jack' in the
back part of turbo R.
Internal PCM uses built-in microphone of turbo R.

Each second takes 150Kb (in 10 frames mode). So each frame takes up 30
sectors.

Well, that is not the reason. The reason is that CD drive 'is not fast
enough' using the same read system that in HDD. EVA player read byte by
byte with a SCSI command, and CDs are not fast enough in that way.
Anyway, you can play EVAs from CD with a modified EVA player made by
Trunks (sorry, I don't remember the URL). But don't expect too much, it just
show frame by frame (with sound) but not in the right time. It is slow.
Furthermore, with this program you can see EVA on a turbo R without
MegaSCSI, because it uses MSXDOS2 file handle system.

Ok... more news; Okei is trying to modify EVA program to digitize more
than 32MB on MSX.
