Dear Customer, This disk contains useful public-domain (can be copied) CP/M compatible software. CBIOS24.ASM - Standard input/output system for Tarbell CP/M and Tarbell Floppy Disk Interface (FDI). Notice that there is now a VDM-1 driver in it, which may be activated by setting the proper EQU's. SBOOT24.ASM - Source for the standard Tarbell FDI coldstart loader program, set up for 24k. COPY.COM, COPY.ASM - Command and source files for a copy program from the CP/M user's group, which has been modified to work with the Tarbell FDI. To use it, type "COPY ALL", "COPY SYSTEM", or "COPY DATA". After typing in the command, it will come back and wait for a carriage-return so you can put your master and fresh disks in. The first form copies the whole disk, track by track, from A to B. The second form copies just the first two tracks, and the third copies all but the first two tracks. After it comes back with the ending message, a carriage-return will do a warm boot, and an ampersand (&) followed by a carriage-return will repeat the operation. TAPELIB.COM, TAPELIB.DOC are the command file and documentation packages for an extensive Tarbell Cassette Interface-CP/M tape library system, written by Sam Singer. It provides capabilities similar to the new PIP, only for cassette tape. For example, you can dump all the files, or all the .ASM files to cassette. DSKCAS.ASM, CASDSK.ASM - These are the sources for simple Tarbell Cassette-CP/M transfers. They are somewhat inefficient compared to those of TAPELIB, since they use only 128-byte buffers. They are used by typing: DSKCAS filename , or CASDSK filename. Of course they have to be assembled first. FORMAT.ASM - This program, written by Dick Culbertson, allows you to completely format a blank or crashed disk. It wipes out whatever is on the disk, so be sure you have all the information off the disk that you need. Also be sure to remove the disk you have in drive A and only have the one you want reformatted in there, when it comes up with it's opening message. This program also needs assembling before use. FBIOS24.ASM - This is the assembly-language source for the dual PerSci version of the Basic Input/Output System. It is usually the same as the standard version, except for the DUAL and FAST EQU statements. Notice that it also contains a VDM driver. Follow the procedure in the CP/M operating system notes entitled "Making Changes in the CP/M System" in order to integrate this module into your system. FBOOT24.ASM - This is the assembly-language source for the dual PerSci version of the coldstart loader program. BASIC.COM, RUN.COM - These are the command modules for the BASIC-E compiler and run-time interpreter, written by Gordon Eubanks, Jr. DISKTEST.ASM - THIS PROGRAM READS THE ENTIRE DISK AND CHECKS IT FOR ERRORS. BE SURE TO EDIT THE SOURCE AND CHANGE THE EQU'S FOR "FAST" AND "DUAL" TO TRUE IF YOU INTEND TO RUN IT ON A DUAL PERSCI DRIVE. SEE THE SOURCE LISTING FOR MORE INFORMATION. STRIP.COM - This program strips a PRN FILE back into an ASM FILE. Command sequence is as follows: STRIP Where is the PRN FILE and is the name of the ASM file you want. The extension .PRN is not needed for , nor is the extension .ASM needed for , as it is assumed that it is a PRN file you are stripping, and it is an ASM file you are building. The STRIP.ASM file is included for academic reasons and requires CP/M's MACRO assembler to assemble it.
