- To Whom it may concern:
-
- This disk contains a recently developed BIOS and support routines
- for CP/M (Copyright Digital Research). The BIOS was developed from rou-
- tines retrieved from the CPMUG, Tarbell Electronics, DR's CP/M 2.0 and
- J. S. Singer. It is meant to operate as a full blown BIOS under CP/M 2.0.
- In particular, it was developed to give the full disk capabilities that
- CP/M 2.0 and DFOCO, a disk utility by S. J. Singer, provide. It supports
- single and double density disks with 128, 256, 512 or 1024 sector sizes.
- The non-disk drivers fully support the virtual re-assignments allowed via
- the IOBYTE. Also, special utilities are provided to give the user quick
- access to the new functions being supported.
-
- The BIOS may be as large as 2.75k. Currently, it is limited to
- .75k by the way its stored on the diskette. To provide more room, I put
- the CCP on the disk as a regular disk file. For warm or cold starts, I
- merely open it as a regular file and read it in. Unfortunately, this
- takes more time than I really like due to required system overhead (I.E.
- System Reset, Disk Select, etc.). In the future, I plan to change it so
- that 3 tracks are used for system tracks instead of two.
-
- To generate the system, follow the instructions given in the BIOS.
- You will use files, 21BIOS.ASM and 21BOOT.ASM. The system generation is
- almost the same as if you were doing it for any old CP/M. To regenerate
- the system under itself, you MUST use the NPGEN.ASM file instead of SYSGEN
- and 21BOOT.ASM. These instructions can be found in the front of NPGEN.ASM.
- Please insure that you are familiar with system generations before tackling
- this one. Also, always keep a backup of your old system. This thing can
- become tricky!
-
- I look forward to any constructive comments and suggestions.
-
- Respectfully,

- 1. It may seem that some the files on this tape are repeats of old ones.
- Be advised that ALL files have been updated. That is, they are dif-
- ferent from the old ones. Please don't try to interchange them.
-
- 2. System generations may be hazardous to the health of your current sys-
- tem if you don't back it up. Always do so! Also, generate the new
- system 16k smaller than your current one. Then to check out problems
- with DDT, you can re-boot your current system and look at the new BIOS's
- areas.
-
- 3. All programs on this disk require MAC, the macro assembler distributed
- by Digital Research.
-
- SCRAMBLE is a command used to encode a CP/M file.
-
- The format of the command is:
- SCRAMBLE filename.type password
- where "password" is an 8 character password made of characters
- perissible in a file name (i.e. no ".", etc). To obtain a good
- "initial seed" for the scrambling process, no character in the
- password may appear more than twice.
-
- The requested file is scrambled, and re-written in place.
- To un-scramble the file, the IDENTICAL command is issued,
- i.e. SCRAMBLE filename.type password. This is because
- SCRAMBLE does an "exclusive-or" type modification to the file,
- and doing two identical exclusive-or's to data result
- in the same data being retuned.
-
- I feel a scrambled file is quite secure. Given that a file
- was scrambled and the password forgotten, I know of no way to
- determine what the original file was. Even a file which
- is all binary-0's, is sufficiently scrambled to defy finding
- out what the password or original data was. ...But I assume
- no responsibility for the "security" of files scrambled
- with SCRAMBLE as I am not a "student of cryptology".
-
- Note also, that if an attempt is made to unscramble a scrambled
- file, using the WRONG password, then the file is technically
- "double scrambled" and SCRAMBLE would then have to be executed
- TWICE, once with the original password, and once with the
- erroniously-used password. Because of the exclusive or-ing
- process, either password may be used either time.

- SORTV.DOC (vevised 1/14/81)
- Brief commentary on the use of SORTV
- by Ward Christensen
-
- SORTV is a "simple" sort program for variable length (CR/LF
- terminated) record files, i.e. the typical CP/M file of
- lists of things. It defaults to sorting from the 1st char
- in the line, but can skip past any particular characters
- that occur in the file. The file being sorted must fit
- in memory. You may write back to the input file, or to
- another. /// A typical use would be to sort a list of
- filenames into filetype sequence, i.e. names.sub from FMAP.
- Some examples: If you want to sort "files.nam" into se-
- quence: SORTV FILES.NAM; To sort a list of names (as pro-
- duced by FMAP *.* Q, for example) by filetype:
- SORTV NAMES.SUB @. The "@" means to sort "at", and the "."
- means at the period. Note EACH line must have the skip-
- character specified. To sort a file skipping a period,
- a comma, and 2 spaces: "SORTV NAME @., " where you put 2
- spaces after the ",".
-
-
- Here's the general way to execute SORTV -
-
- To write back to file in place: SORTV name
-
- To write to another: SORTV inputname outputname
-
- If you should want to use a tab as a skip character, you
- must either specify an output filename, or use a single
- "." for the output name (causes input to be overlaid with
- output) This is because CP/M doesn't like having a con-
- trol character in a place it considers to be a filename
- (one of its two it may take on a command). Thus to skip
- a tab, a period, and another tab, writing "FILE" back to
- itself: SORTV FILE . @^I.^I where "^I" means you pressed
- the "tab" key. If you typed: SORTV FILE @^I.^I CP/M would
- reject the command because it thinks you are putting a
- tab into the second (output) filename. P.S. bug: file must
- end with cr/lf. Enjoy.
