The B5500 simulator supports the following peripherals. Two CPUs with between 4K and 32K of memory. The second CPU can be enabled with "set cpu1 enable". "set cpu1 disable" disables the second CPU. Up to 4 floating IO channels. Individual channels can be enabled with "set io# enable", or "set io# disable". There are two card readers. The second reader is disabled by default. There is one Card Punch. The Card reader and Card Punch support the following options: set cr format= auto - will automatically determine the format based on the text it recieves. text Text based cards. Tabs are converted to the correct number of spaces. A record of ~raw octal will enter a binary card. ~eor will enter a 7/8/9 punch in column 1. ~eof will enter a 6/7/9 punch in column 1. ~eoi will enter a 6/7/8/9 punch in column 1. ~~ will enter a ~ as the first character. bin Binary Card format: Each record 160 characters. First characters 6789---- Second character 21012345 111 Top 4 bits of second character are 0. It is unlikely that any other format could look like this. bcd BCD Format: Each record variable length (80 chars or less). Record mark has bit 7 set. Bit 6 is even parity. Bits 5-0 are character. cbn CBN Format: Each record 160 charaters. First char has bit 7 set. Rest set to 0. Bit 6 is odd parity. Bit 5-0 of first character are top 6 bits of card. Bit 5-0 of second character are lower 6 bits of card. For punch format of auto if the card can't be converted to text it is output as a raw record. There are two line printers, the second one is disabled by default. The LP supports the option "set lp# linesperpage=#" which determines when the printer will force out a page break. There are up to 16 mag tape drives, the format is controlled by the standard simh format control for tapes. These are 6 bit tapes, 1 character per record with parity. Units 8-16 are disabled by default. There are up to two drum units DR0 and DR1. These can either be attached to a file or set to AUXMEM. Setting to AUXMEM causes them to exist only during the given simh run. Setting back to DRUM will clear whatever was stored on the drum. To enable use of DRUM on XV the following options should be turned on "DRA,DRB,CODEOLAY,DATAOLAY". MCP will then use the drum as a overlay device instead of the disk system. Disks can be attached to the various ESU's, ESU0-9 are on DKA by default, ESU10-19 are on DKB. If "set dk1 dfx" is set, then ESU10-19 are not used and the disks are shared by both DKA and DKB. To use more then 10 ESU's in a non shared mode, a new version of MCP must be created. MCP must be compiled with DFX option set to false. For MCP XV DKBNODFX must also be set to true. ESU units can be set to MODI or MODIB. MODIB will double the size of the drive. The DTC can be attached to a telnet port with "attach dtc #" to enable dialup access to the sim. The loader card for the card reader is: ~raw0104441100204231524012004000004444550211002041317700000000000024045303040243 00050000006501004131011041310055005500000062005042310000006600304231000000720010 42310000007675610165001002310010413100040107202500440106202533554061256520252265 20251765202514655355536117650000004401062025155522610165225572610465044101160500 4131 This card should be all in one line.

This is the standard card reader.
|
||
This is the standard card punch.
|
||
|
||
Input formats are accepted in a variaty of formats:
|
||
Standard ASCII: one record per line.
|
||
returns are ignored.
|
||
tabs are expanded to modules 8 characters.
|
||
~ in first column is treated as a EOF.
|
||
|
||
Binary Card format:
|
||
Each record 160 characters.
|
||
First character 21012345
|
||
111
|
||
Second characters 6789----
|
||
Top 4 bits of second character are 0.
|
||
It is unlikely that ascii text or BCD format
|
||
text could produce similar profile.
|
||
|
||
BCD Format:
|
||
Each record variable length (80 chars or less).
|
||
Record mark has bit 7 set.
|
||
Bit 6 is even parity.
|
||
Bits 5-0 are character.
|
||
|
||
CBN Format:
|
||
Each record 160 charaters.
|
||
First char has bit 7 set. Rest set to 0.
|
||
Bit 6 is odd parity.
|
||
Bit 5-0 of first character are top 6 bits
|
||
of card.
|
||
Bit 5-0 of second character are lower 6 bits
|
||
of card.
|
||
|
||
For autodetection of BCD card format, there can be no parity errors.
|
||
All undeterminate formats are treated as ASCII.
|
||
|
||
Auto output format is ASCII if card has only printable characters
|
||
or card format binary.
