+====== Getting Started with Simple80 ======
+===== Introduction =====
+This is a guide for setting up Simple80 after assembly is completed and the board is fully populated. The assembly instruction for Simple80 is [[builderpages:plasmo:simple80:step_by_stem_assembly|here]].
+===== Program the EPROM =====
+Simple80's EPROM socket can accept both 28-pin EPROM device such as 27C512 or 32-pin EPROM device such as AT49F040. Two EPROM programming files are supplied in the [[builderpages:plasmo:simple80|Software section]]: Simple80_Monitor and SCMonitor_for_Simple80. Only one of the file should be selected depending on user application. To run CP/M2.2, Simple80_Monitor needs to be programmed in the EPROM. The remaining document assumes Simple80_Monitor is programmed in the EPROM.
+===== Power up Simple80 =====
+Simple80 requires 5V power at a minimum of 250mA. The power comes in through a 2.1mm X 5.5mm power plug with center lead as 5V and barrel as ground. A CP2102 6-pin USB-to-serial adapter can be plugged directly in P2. A serial emulator such as TeraTerm is needed to interface to Simple80. The serial port setting are 115200 N-8-1.
+Insert a CF disk in the CF adapter prior to powering up.
+Apply 5V power, the power consumption should be around 60-80mA and the terminal should display this log on message:
+//>Simple80 Monitor v0.6 7/2/19//
+Type 'h' to display help menu.
+Type 't' follow by carriage return to do memory test. It should print 'OK' every second or so. type carriage return to stop memory test
+===== Prepare CF disk for CP/M2.2 =====
+Format the CF disk by type 'x' follow by drive letters 'A', 'B', 'C', 'D' in **upper case.** Please note this will erase whatever files that was in the CF disk.
+Send [[https://www.retrobrewcomputers.org/lib/exe/fetch.php?media=builderpages:plasmo:simple80:simple80_cpm22_release.zip|cpm22all.hex]] to Simple80. In TeraTerm 'send' means File → Send file… → pick the file in drop down menu.
+Once send is completed, type 'c2' followed by carriage return to save cpm22all in CF disk.
+Once cpm22all is saved in CF disk, it can be invoked by type 'b2' followed by carriage return. The CP/M sign on message will display
+//Copyright 1979 © by Digital Research\\
+CP/M 2.2 for Simple80 Rev 0.2 IOByte & JmpTbl 7/2/19//
+//a>//
+Once in CP/M environment, press reset button to return to Simple80 monitor.
+In Simple80 monitor, send [[https://www.retrobrewcomputers.org/lib/exe/fetch.php?media=builderpages:plasmo:simple80:simple80_cpm:xmodem.hex|xmodem.hex]].
+Once send is completed, type 'b2' to enter CP/M2.2. At CP/M command prompt, type 'save 17 xmodem.com' to save RAM image as xmodem.com. This will create the first file on the new CF disk.
+xmodem is used to transfer all subsequent files to the new CF disk. The command is “xmodem filename /r”. Start xmodem transfer in TeraTerm: File→Transfer→XMODEM→Send and pick the file to send.
+File file to transfer via xmodem is [[https://www.retrobrewcomputers.org/lib/exe/fetch.php?media=builderpages:plasmo:zz80cf:unarj.zip|unarj.com]] ← please note this file needs to be unzipped first into unarj.com
+Second file to transfer is [[https://www.retrobrewcomputers.org/lib/exe/fetch.php?media=builderpages:plasmo:zz80cf:cpm22dri.zip|cpm22dri.arj]] ← please note this file needs to be unzipped first into cpm22dri.arj
+cpm22dri.arj is compressed CP/M22 distribution. To uncompress it, type 'unarj e cpm22dri'. Once the decompression is done, CP/M2.2 is ready to run!
