Tested in Oracle Virtual Box 5.0 on Linux Mint 17.2 and Windows 7. The CTOS III.vdi contains the following software: OS & Standard Software: 1) CTOS III, vStnd s1.3.5 (Standalone OS, no cluster support) 2) Standard Software R12.3.128 (Standard commands and Utilities) 3) Software Development Utilities (Linker, Librarian, Assembler, CTOS libs, etc) 4) System Build Utilities (SBU) for CTOS III R1.1. The System Build Utilities provide all the files needed to build (SysGen) a customized CTOS operating system. This release of the System Build Utilities includes a new system utility, the Mini Customizer, that allows the administrator to modify certain sysgen parameters without linking the operating system. Additional System Software: Context Manager s5.1.3 GPS (Generic Print System) s2.7.7 ISAM II s1.2.6 Environment Service Read, Write, Dir MSDOS floppies (or floppy images) Compilers: BASIC Compiler 6.1.2 C Compiler s1.2.2 Pascal Cpmpiler s7.0.11 PLM Compiler V2.386 Applications: Art Designer 1.0 (does not work, thinks there is no graphics controller installed) Multiplan 3.1 (Spredsheet) OFIS Document Designer R3.1.100 (Word Processor) OFIS Organizer 2.1.0 (Calendar, notes, scheduler, Calc, etc.) Database: RBase 5000 1.2 (Database, requires ISAM) Utilities: IFM (Informed File Manager, 3rd party app) Zip, Unzip and other CTOS compression Utils CTOS Tool Kit 1.0 (UNIX like commands, grep, awk, etc.) Notes: 1) The keyboard has been remapped to be more CTOS-like. Specifically, the "<" and ">" keys are swapped with the "{" and "}" keys to make it more convienient to enter [vol] paths. The Functin keys have been remapped as in the example below: ------------------ ----------------------- ---------------- | | | || | | | || | | | |Redraw|Undo|Set Up||Files|Print|Views|Tools||Cancel|Clear|Go | | | | || | | | || | | | ------------------ ----------------------- ---------------- | /|\ | | | | | | /|\ | | / | \ | | | | | | / | \ | F1 F2 F3 F4 F5 F6 F7 F8 F9 F10 F11 F12 2) Key Mapping (with Num Lock on): CTOS -> PC ACTION - HOME (on the numeric keypad) ACTION-GO - SYSREQ/Print Screen BOUND - DEL (on the numeric keypad) CANCEL - ESC CODE - CTRL COPY - Page Down (on the numeric keypad) FINISH - Page Up (on the numeric keypad) GO - ENTER (on the numeric keypad) HELP - ALT-F1 JUMP - Note: not available. (reports indicate that CODE-J might work). MARK - INS (on the numeric keypad) MOVE - END (on the numeric keypad) NEXT - (on the numeric keypad) NEXT PAGE - Page Down OVERTYPE - INSERT PREV PAGE - Page Up REDO - F1 RETURN - ENTER SCROLL DOWN - (on the numeric keypad) SCROLL UP - (on the numeric keypad) Problems: 1) Keyboard handler is a little flaky, especially using the Editor. Note: to inspect files use the IFM program. 2) No support for additional addapters, like Ethernet and possibly Comm ports.
