| 7 | Revision History:\r |
| 8 | \r |
| 9 | 2004.10.22 - Removed stub for xio_1134_papertape as it's now a supported device\r |
| 10 | \r |
| 11 | 2003.11.23 - Fixed bug in new routine "quotefix" that made sim crash\r |
| 12 | for all non-Windows builds :(\r |
| 13 | \r |
| 14 | 2003.06.15 - added output translation code to accomodate APL font\r |
| 15 | added input translation feature to assist emulation of 1130 console keyboard for APL\r |
| 16 | changes to console input and output IO emulation, fixed bugs exposed by APL interpreter\r |
| 17 | \r |
| 18 | 2002.09.13 - pulled 1132 printer out of this file into ibm1130_prt.c\r |

| 28 | *\r |
| 29 | * Notes about overstrike mapping:\r |
| 30 | * The 1130 console printer used a Selectric typewriter element. The APL interpreter\r |
| 31 | * used overprinting to construct some APL symbols, for example, a round O overstruck]\r |
| 32 | * with | to get the greek phi. This doesn't accomodate a glass terminal! Instead,\r |
| 33 | * modern APL fonts have separate character codes for the complex characters. \r |
| 34 | * To have APL\1130 output appear correctly, we have to do three things:\r |
| 35 | *\r |
| 36 | * use simh's telnet feature to connect to the 1130 console stream\r |
| 37 | * have the telnet program use an APL font\r |
| 38 | * detect combinations of overstruck symbols, and generate the approrpiate alternate codes.\r |
| 39 | *\r |
| 40 | * There is a built-in table of font mappings and overstrike mappings, for the APLPLUS.TTF\r |
| 41 | * truetype font widely available on the Internet. An font descriptor file can be used\r |
| 42 | * to specify alternate mappings.\r |
| 43 | *\r |
| 44 | * The APL font codes and overstrike mapping can be enabled with the simh command\r |
| 45 | *\r |
| 46 | * set tto apl\r |
| 47 | *\r |
| 48 | * and disabled with\r |
| 49 | *\r |
| 50 | * set tto ascii (this is the default)\r |
| 51 | *\r |
| 52 | * APL also uses the red and black ribbon selection. The emulator will output\r |
| 53 | * ansi red/black foreground commands with the setting\r |
| 54 | *\r |
| 55 | * set tto ansi\r |
| 56 | *\r |
| 57 | * The codes can be disabled with\r |
| 58 | *\r |
| 59 | * set tto noansi (this is the default)\r |
| 60 | *\r |
| 61 | * Finally, when APL mode is active, the emulator does some input key translations\r |
| 62 | * to let the standard ASCII keyboard more closely match the physical layout of the\r |
| 63 | * 1130 console keyboard. The numeric and punctuation key don't have their\r |
| 64 | * traditional meaning under APL. The input mapping lets you use the APL keyboard\r |
| 65 | * layout shown in the APL documentation.\r |
| 66 | *\r |
| 67 | * The translations are:\r |
| 68 | * FROM\r |
| 69 | * ASCII Position on keyboard To 1130 Key APL interpretation\r |
