IBM 5110 Emulator
|
IBM 5110 | --> | PC |
---|---|---|
ATTN | Esc | |
HOLD | Pause/Break | |
CMD | Ctrl | |
EXECUTE | Enter |
In case of error messages in BASIC, you will not be able to enter anything. You have to press the "ATTN" key ("Escape" on the PC keyboard), first. Then you can correct the entered line or press "ATTN" again to clear your previous input. A backspace key is not there on the 5110 keyboard. Use the "left" key (cursor left on the PC) instead.
Try some BASIC commands like "PRINT 19 + 7", etc.
Get the directory listing of floppy disk 1 by entering "UTIL DIR,D80".
Load the operator training program from disk by entering "LOAD 'INTRO',D80" and run it by entering "RUN".
There are currently the following four floppy disks:
Drive | Disk | |
---|---|---|
1 (D80) | Customer Support Functions | |
2 (D40) | Diagnostic Diskette | |
3 (D20) | Serial I/O Diskette | |
4 (D10) | Empty disk |
To switch from BASIC to APL, press the "APL" switch, and then press the "RESTART" switch. Going back to Basic is the same with the "BASIC" switch first.
For much more read IBM's great manuals at bitsavers.org.
There are also some bugs and still many missing features: The "HOLD" key does not work properly in BASIC mode. The tape and disk drives of the IBM 5110 are not yet emulated. The switch to display the registered is not yet implemented. Some keys might not be mapped corectly (I have only a German keyboard to test it). Etc.
Have fun.
