Pulsar Little Big Board 8" TurboDOS disk images - ChickenMan - 31-03-2023
Thanks to grahaml who tirelessly imaged 500+ 8" disks that he acquired with a Pulsar LBB system, all imaging with a Greaseweazle. Approx 1/3rd had major errors, another 1/3 were not Pulsar disks with the rest a mixture of Pulsar CP/M 2.2 and Pulsar TurboDOS disks. The CP/M disks have been released already, these are the TurboDOS disks. The other disks were in standard IBM single sided, VesaFloppy, JADE DD both single and double sided, Positronics or a few unknown formats which Graham will release to archive.org.
There were 32 TurboDOS disks recovered and were supplied in HFE format. These are included here to allow them to be written back to a 8" disk or to a 5.25" 77/80 track drive with a Greaseweazle. The HFE files were converted with the latest HxCFloppyEmulator to a IMG (raw sector file format) image. The disks structure had little resemblence to the CP/M disk, so a new CPMTools (NOT for the modified/patched CPMTools) diskdef entry to extract/add files was written for these 8" IMG images. Add this to your un-patched CPMTools diskdef file if you wish to extract/add files or just get a directory of a IMG file -
# Pulsar LBB - TurboDOS 8" DS DD 77Tr (8" DS DD 77Tr 9 s/t 1024b/s )
diskdef lbb_77turbo
seclen 1024
tracks 154
sectrk 18
heads 2
blocksize 2048
maxdir 256
skew 0
datarate DD
boottrk 1
os 2.2
end
So all the files were extracted from each disk, zipped and attached here also. Use this in cpmtools to get a list of files in the disk IMG image -
cpmls -F -f lbb_77turbo -T raw filename.img
He also provided a very detailed Excel Index file of all the disks, this I cut down for only Pulsar TurboDOS disks and it includes a directory of each disks file contents. Too big to post but attached here, so read one of the Pulsar_TurboDOS_Index files for a directory of the files on each disk image. Many disk contain no files in User 0 but are in other User areas and some disks contain only one small data file as well. TurboDOS v1.3 is for 8 bit systems while v1.43 is for 16bit systems. Pulsar TurboDOS Manuals will follow when scanned. The disk labels indicates some of the contents of each disk -

So in the Vintage Repository in the Pulsar\Disks\TurboDOS_8inch folder we placed
The above 32 disk numbers in HFE and extracted Files in ZIP files as -
Pulsar_TurboDOS_xxx_files.zip
Pulsar_TurboDOS_xxx_hfe.zip
Pulsar_TurboDOS_Index.ods
Pulsar_TurboDOS_Index.xls
