first words

-----------



This program is a rewrite of the great MDC from Wolfgang Bertsch.
But now completely written in C99 and assembly language.

The MDC supports SCSI harddisks, ZIP drives and normal disks.


.CE 1
!!!! Becarefull !!!!

There are two versions of the MDC:
MDCM1 is for Mechatronic Gram card and MDCH1 is for the HSGPL card.   

If you use the Mechatronic version with the HSGPL card, the HSGPL card surely
will be deleted!



The CRU adresses of both cards should be >1B00 !
.SP 5

hardware configuration

---------------------- 



absolutely necessary is the following hardware:

- TI-99/4A

- 32K RAM

- 80Z card (z.B. EVPC, Mechatronic, Dijit)

- SCSI card wit  ZIP drives or Harddisks 

- Diskcontroller with diskdrives



further supported are:

- Mechatronic Gramcard

- HSGPL card of M. Becker

- Gram-Modul without special CRU bits

- printer 

- TI thermoprinter
- mouse on the color bus

.SP 5

limits:^^^^^^^^^^^^^^^^^^127 files in one directory

^^^^^^^^^^^^^^^^^^^^^^^^^114 subdirectories in one directory

 

pathlength:^^^^^^^^^^^^^^30 characters





memory:^^^^^^^^^^^^^^^^^^about 28k CPU-RAM and 48k VDP-RAM

handling

--------



On the bottom there is a functionline. Pressing any responding function key
will process a function. The process is always active on the active window.

The active window is the window with the red cursorline.

In the inputfields there are the standard TI function keys active. You finish
the input with the ENTER key.



SPACE

Pressing the SPACE key will mark or unmark the files.



CURSOR keys

Moving the red cursorline..



F1>del

Deleting all marked files.
If a marked subdir is full it won't be deleted. The MDC controlls if there are
files in the subdir.



F2>ren

Renameing the file on the position of the cursorline.


F3>mov

Copying files to the opposite. After the copy process the program asks to
delete the files.



F4>shw

Showing all marked files. If program files are marked there will be an error
prompt.



F5>all

Marking all files.



F6>cpy

Copying all marked files to the opposite window. Subdirs won't be copied.
You may stop the process by pressing F4>BREAK. 



F7>dir

Make a subdirectory.



F8>pat

Input the pathname. A point at the end of the path is not necessary. 



F9>u/p

Protect or unprotect the marked files.



F10>./.

Go one step back on the path.



F11>QUIT

Jumps to the TI title screen.



CTRL E

One page upwards in the catalog.



CTRL X

One page forwards in the catalog.



G

Load GRAM programs. All marked files will be tried to load into GRAM memory.
You should only mark always the first program file.  All necessary files will
be loaded automaticly. The next program needs a new GRAM base adress. E.g. the
Mechatronic card needs the following adresses >9800, >9808, >9810 ...  

 
The MDC uses the 4 Byte header format of the HSGPL card.



R

Load and start a program. With this option you may start programs in the
Editor/Assembler option 5 format.



ENTER

Tries to change to a subdirectory. 



P

Printing the actual catalog.

.SP 5

customizing

-----------



Like all C programs the MDC needs a characterset file CHAR@@3.
If it doesn't find this file it jumps to the TI title screen! The path and
filename may be changed. Use e.g. the program Diskreview, examine the first
program file of the MDC and change the path
"DSK5.CHAR@@3". Becareful the byte before the pathname is the length of the
name. You must change it. You also may change the starting path of the
catalogs and the printer name. These both names have no byte for length but
they need a NULL byte after the last character.
