As far as I can tell, the drives in a uvax II are the standard rx50's -- high density, single sided. I've seen Verbatim floppys of the same sort for sale; there are probably others too. I seem to remember that when the Rainbow first came out there wasn't a format program, but that one appeared later. Can't vouche for that, though, since I've never dealt with Rainbows that much. I've heard of people formatting disks on a Rainbow and using them on uvaxes, though. If you really want to, you could use the double sided, high density floppies, ie., ones for an AT/RT drive just fine, since they're certified for the same density, and on both sides too. I don't know about the possibilities of flippys, though. Fly to the sky on GI-GI_________ and shout to -------

I use single or double sided floppies double density floppies in my rainbow. We use a rainbow to format floppies for the micro vax. DEC claims that hub rings cause problems but to date have had no problems with hub rings. Latest batch of floppies were 29 cents per floppy (quantity 100) from some where in Ohio. No problems. To format them on the microvax requires a program that DEC only provides with the onsite maintenance programs (extra money) - Arthur T.

In a lab I used to work in we had an 11/73 with the same type of floppies. We used non-DEC floppies formatted on a Rainbow and had no problems at all with the disks. If you can find a Rainbow and the formatting program, give it a shot. --ted Ted Ede ted@mitre-bedford.arpa

"Finding" the formatting program shouldn't be hard -- it's on the MS-DOS distribution diskette. No, in the bad old days of DOS 2.01 it wasn't included, but DEC was quickly flamed into submission and included it on the 2.05 and 2.11 distributions. If you only have 2.01 you should upgrade for lots of other reasons too -- the 2.01 BIOS stinks. If you have a Rainbow under maintenance DEC will send you the latest version of DOS for the asking. -- Larry Campbell The Boston Software Works, Inc.

As I understand it, the Rainbow MS-DOS format program will NOT produce RX50's. You need to use the Rainbow CP/M format utility. It is supplied with CP/M V2.10 (I don't know about previous versions). With this program you can "make" RX50's from any (soft-sectored) SS-DD diskette. You can use DS-DD disks, but the second side will not by used by DEC equipment. DEC recommends you use disks without hub-rings; though I haven't had any problems (yet) with hub-rings. -- Erik A. Abers -- 501 N. 36th.
