MPU302 Software Updates
The assembly language software were assembled with EASy68K tool, downloadable from www.easy68k.com
The AMbug monitor, BIOS for CP/M-68k, drive A & B may be updated with the following procedures. Use the “send text file” command of your terminal program to upload. This program will auto-execute when file loading is finished. When program execution is completed it will display “S record execution completed” and prompt for more inputs.
CPM BIOS updates
There are 4 pieces of software for CPM updates: CPM15000, BIOS, utility software to clear memory, and flash programming software to copy CPM15000+BIOS into flash. The software can be uploaded individually as follow:
- Upload clrCPMmem.s68. This program will auto-execute when file loading is finished. When program execution is completed it will display “S record execution completed” and prompt for more inputs. Please note that source & listing are also included in the zip file, only upload the file with .s68 extension
- Upload CPM15000.s68.
Upload MPUBIOS_v2.s68 (note: the source & listing are also included in the zip file, only upload the file with .s68 extension)- Upload MPUBIOS_v2_1.s68 ← this is 12/26/17 update replacing MPUBIOS_v2.S68
- Upload progCPM.s68. This program will auto-execute when file loading is finished. When program execution is completed it will display “S record execution completed” and prompt for more inputs.
Alternatively a combined program, progCPMall.S68, can be uploaded that will do all the above in one upload. This program will auto-execute when file loading is finished.← Do not use this method.
Drive A updates
The available flash memories are split into two drives. Drive A contains the CP/M 68K v1.3 distribution files and drive B contains additional utility files. The drive images were created using cpmtools. The image is first loaded into MPU302 RAM and then programmed into flash memories. Drive A image is larger than MPU302 RAM, so it is split into two parts and uploaded/programmed in two separate steps.
- Part 1 of drive A image. Upload the data file, CPMDSKA1.TXT, first. This is a large file and will take about 15 minutes to load. Next, upload the program file, progdska.s68. It will auto-execute when file loading is finished and copy part 1 of drive A into flash.
- Part 2 of drive A image. Upload the data file, CPMDSKA2.TXT, first. This is a large file and will take about 15 minutes to load. Next, upload the program file, progdskb.s68. It will auto-execute when file loading is finished and copy part 2 of drive A into flash. This will complete the process of updating drive A.
Drive B updates
Drive B is 384K bytes in size and contains additional utilities for CP/M 68K. Upload the data file, CPMDSKB.TXT, first. This is a large file and will take about 10 minutes to load. Next, upload the program file, progdskc.s68. It will auto-execute when file loading is finished and copy the drive B image into flash.
AMbug update
Rev2.07c of AMbug simplifies the hardware handshakes. The file AMbug_prog_010.s68 is used to program primary monitor. The file AMbug_prog_040.s68 is used to program the backup monitor.
Rev 2.07b of AMbug. The file AMbug_prog_010.s68 is used to program itself. The file AMbug_prog_040.s68 is used to program the backup monitor.
