Development Simulators.

This is a working copy of my Burroughs B5500, Dec KA10, KI10, IBM 360 and IBM7000 series simulators for SimH.

Burroughs B5500

This is the same version as in the current simH source tree. It is working correctly as far as I am able to tell. It will currently run MCP XIII and XV.

Dec KA10 & KI10

These are still in the testing stages. Please report any issues that you find in them.

The KA10 sim has successfully run Tops 10 5.03 and Tops 10 6.03.
The KI10 sim has successfully run Tops 10 6.03
The KA10 sim has successfully run ITS.
Support for BBN pager (untested).

Disk

• RC10 RD10/RM10
• RP10 RP01/RP02/RP03
• RH10 RP04/RP06/RP07 (RP07 not supported under 6.03).
• RH10 RS04

Tape

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

Paper Tape

• Punch
• Reader

DC10E terminal mux.

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.

Possibly add in support for KL10A. (No extended addressing).

To do:

• Add support for PMP IBM 3330 drive to run Waits.
• Add support for DC76 for ITS.
• Add support for SA10 for Tymcom-X under KI.

ICL 1900 simulator.

This is a new simulator. It will not quite pass instruction test. Divide does not work also Floating point instructions are not complete.

IBM 360 simulator.

This is a new simulator. There is still much work and testing that needs to be done. The goal is to have it run TOS, DOS and OS/360. If there is interest I might try early versions of MTS, and possibly add in 370 paging support.

It supports the following units:

DASD (Disk)
* 2301, 2302, 2303, 2305, 2311, 2314, 3330.

Tape
* 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 2741 or 1050. (Todo).

IBM 7000 simulators.

Latest status for I7000 Cpus:

i701

• Largely untested.

i704

• SAP works.
• Fort2 unfinished.

i7010

• PR155 works.
• PR108 works.
• Most Diags appear to pass without serious error.
• Protection mode has some errors left.
• Protection mode does not handle setting H or L to 0.

i7070

• Will load Diags, need to remember how to run them to run
• tests on machine.

i7080

• Sort of working.

• RWW, ECB untested.

• TLx instructions implimented, untested, see 8SE

• Will boot from card.

• 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.

• Signifigence mode Not tested, Test Code Needed.
