+====== MPU302 Software Updates ======
+The assembly language software were assembled with EASy68K tool, downloadable from [[http://www.easy68k.com|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 [[https://retrobrewcomputers.org/lib/exe/fetch.php?media=boards:sbc:mpu302:clrcpmmem.zip|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 [[https://retrobrewcomputers.org/lib/exe/fetch.php?media=boards:sbc:mpu302:cpm15000.zip|CPM15000.s68]].
+<del>Upload [[https://retrobrewcomputers.org/lib/exe/fetch.php?media=boards:sbc:mpu302:mpubios_v2.zip|MPUBIOS_v2.s68]] (note: the source & listing are also included in the zip file, only upload the file with .s68 extension)</del>
+Upload [[https://retrobrewcomputers.org/lib/exe/fetch.php?media=boards:sbc:mpu302:mpubios_v2_1.zip|MPUBIOS_v2_1.s68]] ← this is 12/26/17 update replacing MPUBIOS_v2.S68
+Upload [[https://retrobrewcomputers.org/lib/exe/fetch.php?media=boards:sbc:mpu302:progcpm.zip|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.
+<del>Alternatively a combined program, [[https://retrobrewcomputers.org/lib/exe/fetch.php?media=boards:sbc:mpu302:progcpmall.zip|progCPMall.S68]], can be uploaded that will do all the above in one upload. This program will auto-execute when file loading is finished.</del>← 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, [[https://retrobrewcomputers.org/lib/exe/fetch.php?media=boards:sbc:mpu302:cpmdskb.txt|CPMDSKB.TXT]], first. This is a large file and will take about 10 minutes to load. Next, upload the program file, [[https://retrobrewcomputers.org/lib/exe/fetch.php?media=boards:sbc:mpu302:progdskc.zip|progdskc.s68]]. It will auto-execute when file loading is finished and copy the drive B image into flash.
+===== AMbug update =====
+[[https://retrobrewcomputers.org/lib/exe/fetch.php?media=boards:sbc:mpu302:ambug207c.zip|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.
+<del>[[https://retrobrewcomputers.org/lib/exe/fetch.php?media=boards:sbc:mpu302:ambug207b.zip|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.</del>
