It would be great to have support for a tape drive. ams added on 2020-10-05 14:23:25: (text/x-markdown) The tape drive used on the CADR was interfaced using a Western Peripherals TC-131 Controller (see SYS: LMTAPE; TAPE LISP from System 78). The following addresses seem to have been used: ``` (defvar *TAPE-STATUS-REGISTER* #O772520) (defvar *TAPE-COMMAND-REGISTER* #O772522) (defvar *TAPE-MTCMA* #O772526) (defvar *TAPE-MTBRC* #O772524) ``` System 98 and 99 also use this register set, and it seems from a quick glance that the same type of controller is used. ams added on 2020-10-05 14:30:22: (text/x-markdown) The following document exist at Bitsavers on the TC-131: - [Hardware Manual](http://bitsavers.org/pdf/westernPeripherals/TC131_hardware_Apr81.pdf) * [Logic Manual (Rev. A)](http://bitsavers.org/pdf/westernPeripherals/TC131_logic_Mar81.pdf) * [Logic Manual (Rev. B)](http://bitsavers.org/pdf/westernPeripherals/TC131_logic_Mar85.pdf) ams added on 2020-10-05 14:38:05: (text/x-markdown) System 99 added support for the (Ciprico?) Tapemaster. ams added on 2020-10-05 14:41:02: (text/x-markdown) From SYS: TAPE; NEW; WEUNIT LISP (System 99): ``` ;;; Flavors defined in other files: ;;; WEUNIT: WESPERCO-UNIT (used on the CADR, Unibus) ;;; TMUNIT: TAPEMASTER-UNIT (used on the Lambda, multibus) ;;; RMUNIT: RM-UNIT (remote protocol, seems to be CHAOS-independent) ``` ams added on 2024-02-15 19:19:00: (text/x-markdown) BV is working on this. | ||||
