- If you want a copy of the Microsoft F80 and M80 programs as well as
- their support software and you want to get them with free updates for a
- year and be a legal user read on. While not free, Heathkit sells these
- programs, doctored up so they only run on Heath systems, at a discount.
- The discount is quite steep and the free updates are attractive. You
- will need to know about DDT and SAVE to fix them so you can use them.
-
- The following programs which are configured to run on Heath equipment
- can be altered to run on other computers by making the changes as
- follows:
-
- MBASIC.COM 5.21
-
- Change address 5F08 to JMP 5F5C
-
- OBASIC.COM 4.83 (On Disk w/MBASIC 5.21)
-
- Change address 4D3A to JMP 4D8E
-
- COBOL-80.COM 4.01
-
- Change address 6199 to JMP 61F0
-
- BASCOM.COM 5.23 (The M80.COM supplied with this disk is ok as is.)
-
- Change address 40F9 to JMP 4151
-
- FORTRAN F80.COM
-
- Change address 2C38 to JMP 2C90
- Exit from DDT and do a SAVE 107 F80.COM
-
- M80.COM (Fortran and Cobol Disks)
-
- Change address 4392 to JMP 43EA
- Exit from DDT and do a SAVE 75 M80.COM
-
- LINK80.COM (Needs no changes ok as is.)
-
- Use DDT with the "S" command and save the proper number of pages. You
- now have programs that will run on computers other than the HEATH.
-
-
- You now own legal copies of both programs suitable for use on your CP/M
- 1.4 or 2.2 system.
-
- This patch bypasses the vendor code check in the CP/M serial number and
- also bypasses some I/O twitching that must be important for Heath
- systems. The other system programs distibuted on the disk do not need
- patching these programs (LIB, L80 XREF etc) assume if you got to use
- them you must be ok.
