There are some pieces around which may help him/her get files across, but it'll take a bit of work. First, reading the RX50 media. There's a driver for msdos (RX50.arc on various BBSs) which will read and write (but NOT format) RX50 media on the PC/AT's 1.2 meg diskette drive. That works nicely and will handle media from Rainbows out of the box. However, on a Pro one runs either RT11 or POS, which uses the RSX-11 file structure. In the case of RT11, there are sources around in the CP/M world at least (on simtel20?) that let you read RT11 media under CP/M. These ought not to be TOO hard to hack up. Under RSX, a program called GETRSX is available. It has even appeared somewhere in the DECUS library, though probably on a SIG tape (read those abstracts CAREFULLY). Its purpose in life is to read ODS-1 file structures (which the pro uses) and grab files off them under different OS's. It was written for unix or rt-11 (don't know which), but again since the C sources ARE available, some hacking ought to get it across. You'll need to add ability to use named directory files of up to 9 characters, instead of the numbered 6 character octal directories; P/OS shares with the newer RSX versions the use of named rather than numbered directories. You also may want to figure out something to do with filename and version conflicts; the RSX namespace of 9.3 chars and version numbers introduce problems where you just try to copy things over. These look to me like the most promising approaches. If the pro is still available, of course, I suggest simply Kermiting over whatever is desired. Glenn Everhart Everhart%Arisia.decnet@ge-crd.arpa
