Subject:  RE: SEDT USERS - HOW MANY
From:     BOB FULLER

I use SEDT and find it extremely helpful.  For example, when I inport
text files between programs, I find SEDT helps me find and erase
control characters that don't show up using the program, but do effect
the program's operation.

From:     BOB FULLER

  Here are some solutions that may work in recovering the SELECT files

  1. Recopy both the text and program files.

  2. Using the flopies and the hard drive, CREATE a new document
from the original file.

  3. Using the original flopies and the RDCPM program, copy the CPM
files to MS-DOS.  FREESTYLE will automaticly change the document so it
can be used with FREESTYLE.  It will also make ASCII files.

  4. Using the original flopies and the RDCPM program. copy the CPM
files to MS-DOS.  Edit out the control characters using SEDT and
re-edit using WordPerfect or another word processor.

  Good luck.

Bob

Subject:  CACHE PROGRAM
From:     MARK BUDA

I have been looking for a cheap cache program that I can run on my rainbow.
SS used to sell a cache program, but of course they seem to have moved on.

If anyone has information, please let me know.  This would be used on
my BBS,  to speed up processing of mail.

        Thanks,

Addressing the "HD" part of your question, it refers to HIGH DENSITY,
which is IBM'ese for 96tpi. But the fly in the ointment is that the
coercivity is twice as high as the 48tpi (xxDD) disks, 600 for HD and
300 for the DD.
This is an expression of the strength of the magnetic field required
to change the orientation of the magnetic media on the disk. While the
HD disks have a track density comparable to that of the RX50, the
RX50's coercivity is more in line with that of the 48tpi disks.
In conversations with Chuck Guzis of SYDEX (author of RainDos, the
RX50 formatting, reading & writing utility for use on PC-AT's), I was
advised EMPHATICALLY to transfer all data off of HD disks, since the
disks were written with a head that did not have enought field
strength to overcome the coercivity of the disk. He predicted that
there would, over time, be some data dropouts. This was true, as the
copy command repeatedly came back with read errors.
I have been using no-name, Sony, TDK, Maxell, Fuji and a few other
DSDD 48tpi disks. I have over 300 disks in my library. Damn few
problems with them, once they were formatted with the "/i" option. I
really don't understand what your concerns are about using these
disks. Would you feel more secure with REAL RX50's from DEC?

It comes down to a choice of DS/DD diskettes or ones designed
specifically for DEC computers (either RX50, or RX180K if you can find them).
I have found the 3M and Memorex DS/DD diskettes to be highly reliable.
Maxell is the only brand I can single out as not suitable for use  on the 'bow.

Generally, it seems that if a diskette passes the format & verify
process on the 'bow, it will thereafter operate reliably.

DS/HD (HD = High Density) diskettes, designed for the IBM 1.2MB drive,
have a coating with a higher coercivity than that of the DS/DD drives;
I tried some and found they wouldn't work, but others have reported
some success with them.

Is Sprint a markup language or a WYSIWYG word processor?

It is *not* technically possible to read or write an IBM 360K floppy
on the Rainbow, for the simple reason that 360K requires two read/
write heads and the Rainbow has only one.

The best you can do is format single-sided on the PC (/1), which when
operated in the MEDIACHK ON mode on Rainbow will give you approx.
180KB.

Kermit is the bargain terminal program you are looking for.
