trs-80 JV3 format added to third party tool Disk-Utilities

Post by magore » Thu Feb 11, 2016 5:11 pm

FYI trs-80 users
Support for trs-80 JV3 (writing only) has just been added to the third party Disk-Utilities by Keir Fraser
(If you have questions I contributed the updates)
This lets you convert Kryoflux CT stream into JV3 format supported by many trs-80 emulators such as sdltrs
(and by TRStools by Matthew Reed which can extract files from the jv3 container)
This updates adds new trs80 FM and MFM format types that understand about the extra directory marks used by the trs-80 dos and ldos formats.
References: https://github.com/keirf/Disk-Utilities (Edit: Feb17 I have sent new updates to Keir that help filter out tracks partly recorded due to cross talk - 40 track disk in 80 track drive - should be available on Keir's site by the weekend or so)

Testing I have done so far
Case 1:
80 track, double sided, 18 sector, MFM
"double density" TRS80 disk from 1982
Kryoflux read on FD-55GRF 80 track drive
# Read from Kryoflux
dtc -d1 -p -fdisk/disk -i0 -i2
# Convert to CT format
dtc -m1 -p -fdisk/disk -i0 -fdisk_trs80_dd.ct -i2 -l0
# Convert to JV3 format
disk-analyse -v -f trs80 disk_trs80_dd.ct disk_trs80_dd.jv3
Case 2:
35 track, single sided, 10 sector, FM
"single density" TRS80 disk from 1982
Kryoflux read on FD-55GRF 80 track drive
# Read from Kryoflux
dtc -d1 -p -fdisk/disk -i0 -i2
# Convert to CT format
dtc -m1 -p -fdisk/disk -i0 -fdisk_trs80_sd.ct -i2 -l0
# Convert to JV3 format
disk-analyse -v -f trs80 disk_trs80_sd.ct disk_trs80_sd.jv3
