OK that didn’t work …..

Digging deeper it seems this is an 8050 format disk but under DOS 2.7 …. from what i can glean dos2.7 can handle or/9 ‘rel' files differently (larger sizes are possible and this one is formatted as 120 tracks instead of 77) which is possibly the cause of why i cannot do anything with this disk.

In Vice what is the DOS version for 8050 drives ?
