I am interested in finding some way to use software that is for the IBM and use it on the DEC Rainbow (or visa-versa). If anyone has any information, I would appreciate it if you could mail me some.

I think you might try first formatting your IBM disk on the IBM using the "1" (single-sided) and "8" (8 as opposed to the 9 by default sectoring) options ... format a:/1/8 Copy the software to the disk and then try running it on the Rainbow under MS-DOS. I've had considerable success doing this with non-hardware specific software, such as a C compiler and a well known Pascal compiler. Good Luck!

<> For the guy who wanted to swap stuff between the IBM PC and the Rainbow, there's this neat little program for the Rainbow called MEDIA MASTER. It allows the Rainbow not only to read but also to format and write disks for at least 24 different systems including the IBM pc. The only significant restriction is that only single-sided, double density formats are available. You can get yours from MDG and Associates, 4573 Heatherglen Court, Moorpark, Ca. 93201.

Ok, folks, here's the scoop on Rainbow <==> IBM file transfer. 1. Reading IBM diskettes on the Rainbow This works fine as long as you format the IBM disk (on the IBM) using the command "format drv:/1". This makes the disk a PCDOS 2.0, 9-sector, single-sided, 180 kbyte format. The Rainbow will read these fine as long as the MEDIACHK function is on (the de- fault). A disk formatted in this way may be read and written on the Rainbow. Once written on the Rainbow, however, it is no longer readable on the IBM, hence ... 2. Reading Rainbow diskettes on the IBM The problem here is that the Rainbow's 96 tpi drive has a head narrower than the PC's 48 tpi drive. If you format on the IBM, the Rainbow will only rewrite part of the track. Then the IBM sees only gibberish. The Rainbow's utilities do not permit formatting a disk in IBM PC format. You need to get a program called "Media Master" (MDG Associates, 4573 Heatherglen Ct., Moorpark, CA 93021, 805 529-5073). This is a CP/M-80 package that will format, read and write disks in about 25 different formats. Now, having to copy all your disks under CP/M is a pain if you use MSDOS, BUT ... it turns out that if you take a brand new unformatted diskette (i.e. NOT a preformatted RX50), format it in PCDOS 2.0 format using Media Master, you can write that disk under Rainbow MSDOS and it will read on a PC 99% of the time. So all you do is crank up Media Master, format yourself a bunch of disks, and use these for transfer. Beware: you cannot write these disks successfully on a PC. 3. So ... What you end up with is two sets of disks: formatted and written on the PC, NOT TO BE WRITTEN ON THE RAINBOW; and formatted and written on the Rainbow, NOT TO BE WRITTEN ON THE PC. Works fine, it's just a little tedious. 4. Software for the IBMPC almost never runs on the Rainbow unless it's really just generic MSDOS. Tony Movshon uucp: ... {ihnp4|seismo|allegra}!cmcl2!hipl!tony

Tony Movshon notes in <152@ur-cvsvax.UUCP> that you can take "a brand new unformatted diskette" and format it on the 96 tpi drive of the Rainbow. You may also be interested to know that you can readily convert any old diskette to "brand new unformatted" condition using one of those inexpensive ($15) bulk tape/diskette erasers available as such places as Radio Shack. I have 96 tpi drives on my IBM PC, and I use this technique to create 48tpi formatted diskettes that I can then read on a typical 48tpi drive. I have never had any difficulty doing this, even though the format of the track must be much narrower than the 48tpi drive would normally create. -- Tom Putnam {decvax|harpo|ihnp4|inuxc|seismo|ucbvax}!pur-ee!pucc-h:ac4
