The '''CR11 Controller''' was a [[UNIBUS]] [[device controller]] for the [[CR11 Card Readers]]. It was a [[DEC card form factor|quad]] format card (M8290), and used an [[Small Peripheral Controller|SPC]] slot; it used [[programmed I/O]].

==Registers==

The device has three control and [[buffer]] [[register]]s, which can be configured to any three sequential [[word]] locations in the I/O page; it is normally configured to [[address]]es 777160-777164:

{| border=1
! Register !! Abbreviation !! Address
|-
|Status Register || CRS || 777160
|-
|Data Buffer Register || CRB1 || 777162
|-
|Data Buffer Register Encoded Output || CRB2 || 777164
|}

In the register contents (below), bits which are read/write or unused are shown in normal font, those which are read-only are in ''italics'', and write-only in '''bold'''.

===Status Register (CRS)===
{{16bit-header}}
| ''ERR'' || ''CARD DONE'' || ''SUPP ERR''|| ''RDR CHECK'' || ''TIM ERR'' || ''RDR ONL'' || ''BUSY'' || ''RDR RDY'' || ''COL RDY'' || INT ENB || colspan=4 | Unused || EJECT || '''READ'''
{{16bit-bitout}}

===Data Buffer Register (CRB1)===
{{16bit-header}}
| colspan=4 | Unused || colspan=3 | ''Zones 12-10'' || colspan=9 | ''Zones 1-9''
{{16bit-bitout}}

===Data Buffer Register - Encoded Output (CRB2)===
{{16bit-header}}
| colspan=8 | Unused || colspan=5 | ''Zones 12-8'' || colspan=3 | ''Encoded Zones 1-7''
{{16bit-bitout}}

The first buffer register is 12-[[bit]] raw data from the card, the second is the compressed Hollerith code (zones 1-7 can have only a single punch, which is encoded in octal in 3 bits; a '0' means 'no punch in any of these').

 The '''CR11 Controller''' was a [[UNIBUS]] [[device controller]] for the [[CR11 Card Readers]]. It could also be used with the GDI 100M Optical Mark Reader, which read 12-row 40-column marked cards; in such use, the complete sub-system was called the '''CM11 Card Reader System'''.

 The original version was the M829, a [[DEC card form factor|dual]] format card, which was mounted in an [[Small Peripheral Controller|SPC]] slot; it was used with an [[M105 Address Selector]] and an [[M782 Interrupt Control]] (both tall singles).

 Later versions were the M8290 and M8291 quad format cards, also mounted in an SPC slot. The difference between the two is not yet known. All the card versions are [[program compatible]].
