- For North Star CP/M version 1.1.0 only.
-
- ***THROW AWAY PREVIOUS VERSIONS OF ALTFORM***
- ***AND THE FORMAT & COPY PROGRAMS BELOW. ***
- ***ALWAYS USE THE NEW FORMAT & COPY PROGRAMS*
- ***AND RETIRE THE ORIGINALS TO THE ARCHIVES**
-
- See next to last paragraph regarding NEWFORM which adds the two new
- formats to your distribution version of North Star CP/M.
-
-
-
- VERSION 1.1 OF NEWFORM IS FIXED SO THAT WHEN ACCESSING FILES ON
- A QUAD FORMATTED DISKETTE WITH THE ALTERNATE 80 TRACK FORMAT BUT
- WITH THE DISKETTE MOUNTED IN AN OCTAL DRIVE, CORRECT READING IS
- DONE FOR ALL 80 TRACKS. FIX IS MADE IN GENUSR45 ALSO. 11/3/82

-
- GENUSR45 is new version as of 11/3/82. If anyone picked up a copy
- of this program prior to this date, it is strongly recommended that
- you start over with this new version. GENSYS41 has been changed,
- and must be used instead of previous versions.
-
- GENUSR45 supports an alternate format for 96 tpi drives when using
- North Star CP/M version 1.1.0. The format byte is now D2H and gives
- a block size of 2kb instead of the 4kb in the North Star release.
- Both 96 tpi formats are supported. So your system can read and write
- disks with either format. (As well as other defined formats in the
- N* release) The block shift factor in the additional format is 4
- instead of the 5 skew factor in the N* format (F2H).
-
- GENUSR45 also now supports an additional format for Quad drives that
- permits using 40 tracks per side. This has been done in such a way
- as to retain the 35 track per side format and to provide complete
- compatibility between the two formats. You do not have to make all
- of your Quad disks either 35 or 40 track/side but can freely intermix
- them. The format byte is D0H.
-
- You will need a formatter that will generate the necessary formatting.
- See NEWFRMAT.COM for a formatter that will do this. Also get a copy
- of NEWCOPY.COM from my system for a copy program that will tolerate
- the D0/D2H format bytes. You can also put these additional formats into
- the distribution version of your CP/M system with NEWFORM.ASM without
- all of the other features of GENUSR. It's a good idea to do this
- because your distribution version will not be able to read disks
- that you have written with these alternate formats otherwise.
-
- For general information on GENUSR, see GENDOC30.DOC that accompanies
- GENUSR37 which is for the Lifeboat bios version of CP/M.
