  • Tape system appear to be working.

  • 8CU10B errors:
    410, 412, 413, 414, 418, 419, 420-427 error becuase storage is not parity checked.
    440 divide not producing correct sign on error.

i7090

  • Working with exceptions.

  • Known bugs:

    • DFDP/DFMP Sometimes off by +/-1 or 2 in least signifigant part of result.
    • EAD +n + -n should be -0 is +0
    • Not all channel skips working for 9P01C.
    • HTx Not sure what problems are, does not quite work.
    • DKx Sometimes fails diagnostics with missing inhibit of interrupt.
  • CTSS works.

  • IBSYS works.

  • Stand alone assembler works.

  • Lisp 1.5 works.

  • Signifigance mode Not tested, Test Code Needed.

Burroughs B5500

Emulates a dual CPU B5500 with up to 32K of memory. I can support either DFX disks or dual disks up to 20 units. Up to 16 magnetic tapes drives is support. 2 Card readers a card punch and a pair of line printers. Will run MCP XIII and XV.

  • Up to either 10 disks with DFX support or 20 disks without.
  • Up to 16 magnetic tape drives.
  • Dual card reader.
  • Dual Line printer.
  • Single card punch.
  • Up to 32 terminal lines.

Dec PDP6

The PDP6 simulator is part of the KA/KI simulator. The PDP6 devices can be built into the KA10 simulator if desired.

The PDP6 runs TOPS 10 4.5 off Dectape.

Disk

  • 270 Disk

Tape

  • 551 Tape
  • 555 Dectape.

Paper Tape

  • Punch
  • Reader

Type 630 Terminal mux.

Type 340 graphics display.

Dec KA10 & KI10 & KL10

The KA10 sim has successfully run Tops 10 4.5, 5.03 and 6.03, ITS and WAITS.
The KI10 sim has successfully run Tops 10 6.03 with VMSER.
The KL10 sim has successfully run Tops 10 6.03-7.03, ITS and Tops 20 V2-V7.

Disk

  • RC10 RD10/RM10
  • RP10 RP01/RP02/RP03
  • RH10/RH20 RP04/RP06/RP07 (RP07 not supported under 6.03).
  • RH10/RH20 RS04
  • PMP (P. PETIT'S IBM CHANNEL)
  • System Concepts DC-10 IBM 2314

Tape

  • TM10A or B
  • RH10/RH20 TM03/TU16
  • TD10 Dectape

Paper Tape

  • Punch

  • Reader

  • DC10E terminal mux.

  • Morton tty Mux for ITS.

  • Knight Kludge mux for ITS.

  • Terminals on KL10 Front End.

  • LP10 Line printer.

  • LP20 Line printer on KL10 Front End.

  • IMP networking support for ITS and TENEX.

  • NIA20 networking support for KL10.

  • CH10 networking support for ITS.

  • 340 Display Station support.

  • III Display support for WAITS.

  • Optional support for PDP6 devices (standard if WAITS included).

The RP10 supports boot (actual hardware did not), by reading in Blocks 4-7 and transfering to the loaded value. RC10, RH10, TM10 support readin mode.

ICL 1900 simulator.

This is a new simulator. Will pass 1904E/1905E CPU diagnostics (FLIT). Will boot paper tape executive E4BM and tape executive E6RM. Still need to add more devices and test with Goerge 2 and 3.

The CPU can be configured for model A, B or C type system. Or models 1901 throgh 1909. Paging is currently not supported. Both standard interface and older non-standard interface are supported on most device.

IBM 360 simulator.

Currently will run TOS/360, DOS/360, OS/360. IBM 360/67 support added for MTS early versions. IBM 370 support will currently run VM/370, MVS, TSS. Support for the following units:

DASD (Disk) Up to 4 devices of 8.
* 2301, 2302, 2303, 2305, 2311, 2314, 3330, 3340, 3350.

Tape, 8 devices.
* 2400 (7 track and 9 track).

Unit record
* 2540 Card reader
* 2540 Card punch
* 1403 Line Priner
* 1050 Console

Communications
* 2703 with 16 lines of 1050.

SEL32 Development Simulator

This is a working simulator for the SEL Concept/32 line of computers. The current test version is for the SEL 32/27, 32/67, 32/87, 32/97, V6, and V9 computers. Support for 32/55, and 32/75 computers may be added in the future. This simulator is co-authors with James C. Bevier. I did the initial parts of the simulator, James took it to a working simulator, I am assisting him in maintaining and enhancing the simulator. This simulator is running a test version of MPX-32 1.5F. It is capable of creating a disk image of the O/S from a SDT tape. The disk image can be booted, initialized, and run many of the MPX utilities; including OPCOM & TSM. Eight terminals can be used to access TSM via Telnet port 4747. Initial support has been added for excess 64 floating point arithmetic. More testing is still required. The sim32disk.gz can be uncompressed and booted with the sel32.27.sim32.disk.ini initialization file. The sim32sdt.tap.gz file can also be uncompressed and started with the sel32.27.sim32.tape.ini initialization file to install from tape.

The current version can also install and run UTX 2.1A from an install tape. It is the SEL version of System V Unix and BSD Unix ported to the V6 and V9 processors. It can run in single or multi user mode. UTX utilizes the basemode instruction set and a virtual memory system provided by the V6 & V9 CPUs. There are still some random halts and panics. The system needs further testing to solidify the SEL32 simulator code.

You can’t perform that action at this time.
