When the emulator starts, it reads the file “cyber.ini” which configures the emulation environment. The file typically contains multiple sections of the following form:
[SectionName] ; comment line keyword1=value1 ; trailing comment keyword2=value2
A typical “cyber.ini” might look like this:
[cyber] model=173 deadstart=deadstart.nos13 equipment=equipment.nos13 clock=3 memory=1000000 ecsbanks=4 pps=12 channels=40 telnetport=6600 telnetconns=4 trace=0 [equipment.nos13] ; eq=type,unitNo,channel 01=DD844,0,01,dd884_1_0_nos13x 02=DD844,0,02,dd884_2_0_nos13x 10=CO6612,0,10 05=CR405,0,11 07=LP501 ,7,07 50=MT669,0,13,nos13.tap 51=MT669,1,13 32=MUX6676,0,05 [deadstart.nos13] 7513 ; DCN 13 3007 ; LDD 07 3415 ; STD 15 1500 ; LCN 00 0000 ; PSN 00 7713 ; FNC 13,0260 0260 ; ... 7413 ; ACN 13 7113 ; IAM 13,6400 6400 ; 0011 ; wxxy w=libdeck, x=cmrdeck, y=dsopts 0000 ; rpss r=recovery, p=-cej,-cpu1,-cpu0, ss=sysondevbits
Each section header is followed by a number of lines specifying parameters to the emulator. By default you need to have the section [cyber]. This can be overridden by a command line parameter when starting the emulator.
The first section is typically named [cyber]. It defines some basic emulation parameters such as central memory size, what deadstart panel and equipment sections to use. It has the following parameters:
| Keyword | Values | Description |
|---|---|---|
| model | 6600 or 173 | Chippewa OS needs 6600, everything else needs 173 |
| equipment | string | Section name containing the equipment definitions. |
| deadstart | string | Name of the section containing the deadstart panel settings. |
| clock | 1 - 10 | Clock multiplier used to match real time clock to wall clock. |
| memory | octal number | Central memory size (1000000 is a good value). |
| ecsbanks | 0, 1, 2, 4, 8 or 16 | Number of ECS banks. |
| pps | 12 | Number of PPUs (must be 12 in this version) |
| channels | 40 | Number of I/O channels (must be 40 in this version) |
| telnetport | decimal number | TCP port number for terminal mux connections. |
| telnetconns | 1 - 16 | Maximum number of TCP connections supported. |
The section named by the “equipment” keyword in section “[cyber]” defines the attachment of peripheral equipment to channels, their unit number and in some cases file names. The following shows the general syntax of an entry:
<est ordinal>=<devtype>,<unit no>,<channel no>[,<optional file name>]
| Device Type | Description |
|---|---|
| CO6612 | Console: unit 0 on channel 10 - no file name allowed |
| MT607 | 7-track tape: normally on channel 5 - file name IS allowed |
| MT669 | 9-track tape: normally on channel 13 - file name IS allowed |
| DD6603 | Model 6603 disk drive - file name IS allowed |
| DD844 | Model 844 disk drive - file name IS allowed |
| CR405 | Model 405 card reader - no file name is allowed |
| LP1612 | Model 1612 line printer - no file name is allowed |
| LP501 | Model 501 printer - no file name is allowed |
| LP512 | Model 512 printer - no file name is allowed |
| MUX6676 | Model 6676 terminal multiplexer - no file name is allowed |
The section named by the deadstart keyword in section [cyber] defines the Cyber deadstart panel settings used to load PPU 0 with a short bootstrap routine. The deadstart panel settings are up to 16 octal values (one per line) representing the deadstart switch settings.
