I had some requests for those versions, which I have finally got around to checking and uploading (along with 'mvall', which for some reason V6 didn't have). I've added them to a couple of my V6 pages: http://www.chiappa.net/~jnc/tech/V6Unix.html#mvall http://www.chiappa.net/~jnc/tech/ImprovingV6.html#FileWrite Note (per the page) that the latter group all require the smdate() system call, which was commented out in 'vanilla' V6 (because using it confused the backup system); the page gives instructions on how to turn it back on.
