So it turns out deleting a read-only file from a ramdisk in MS-DOS 6 is almost impossible locally, but can be done over interlnk thanks to what appears to be a bug in DOS
hooray i think
followup: files were not actually removed, of course; they were only deleted from interlnk's FAT cache
(you can use this trick to copy hidden files, though)
