A long time a go, in another universe it seems, I was using Sintran on an ND-100 at our electronics/computer school. We configured and ran the machine after we inherited it.

These days I am a Cloud Architect, Developer and Geek - and the last years I have been spending an unhealty amount of time writing emulators. You can read how this crazy journey started here [1]

I have successfully (with some help) created an ND-100 emulator in .NET/C# with peripherals such as TeleType, Floppy and HardDrive. (I have to admit I have borrowed some of the thinking and logic from the nd100em emulator)

The emulator contains a debugger, dissasembler and code tracer in addition to logic to mount different floppy-image, loading BPUN and PROG files directly.

I have successfully dumped and booted SINTRAN version H in ND-100 mode, although there are still some bugs to iron out.

I have tried booting SINTRAN K and L. Requires ND-110 it seems. Dumping to HDD works great, but I havent successfully managed to boot SINTRAN from HD with 22! Probably because my MMS-2 isn't behaving correctly (see below) and after a while I end up looping on Page Fault during FETCH on the same address over and over.

I am looking for the following

• Images of SINTRAN J floppies. The source code that has been scanned is SINTRAN J - And it would help immensely in debugging the emulator if I could boot and debug version J.
• Explanation on how MMS-2 is different from MMS-1, especially in regards to Trap
• Documentation on the ND-100 register ACTL (Active Level). Its 3 bits, and its not PIL.
• Other binary images (Tape, PaperTape, HDD, Floppy,+++) All SINTRAN III versions are of interrest.
• ROM's with Microcode for ND-100, ND-110
• Documentation on device and register usage for all peripherals, especially Ethernet
• Access to a REAL ND-100/ND-110 to run som test programs to compare with my emulator.
• Source Code. Any source code. Especially test programs and IO drivers.
• Documentation and Source code for test-program "PAGING-C00:TEST" => "PAGING - Version: C00 - 1986-10-16"
• Documentation on Date/Time format/calculation for file/timestamps

Things I am working on

• I am focusing on getting the ND-10/ND-100 opcodes working 100%.
• Implementing the (semi)missing opcodes

• • Floating point 48 bits (doing 32 bits "buggy" now)
  • «Commercial Extended» (CE) option
  • ND-110 Specific opcodes (Stack, Segment,)
• Focusing on getting SINTRAN H work 100% flawlessly (could be opcodes, but at the moment all my trouble is inside MON 131 ABSTR)
• Test programs that validates the opcodes so far
  • ONE—CHECK, TWO—CHECK, THREE—CHECK, FOUR—CHECK (some bugs here still)
  • INSTRUCTION-B.BPUN (PROGRAM NUMBER: 204384B DATE ISSUED  : 83.11.01)
  • PAGING-B.BPUN (PROGRAM NUMBER: 203098B 1982)
  • FLOPPY-FU-1986F (All tests work except Test 2 "Format Decoder Test" on my PIO floppy driver)
  • Test programs on floppy "210523E00-XX-01D"
    • INSTRUCTION - Version: C00 - 1986-10-30
      • Failing on "32 BITS FLOATING INSTRUCTIONS" (NLZ, FMU,FDV, FAD,FSB)
      • Failing on "INTERNAL INTERRUPTS" (Expected IIC value:5, Found IIC value: 2)
    • PAGING - Version: C00 - 1986-10-16 (Detected MMS-1 in ND-100 mode)
      • Test 5 fails on "RING VIOLATION interrupt". Refers to read NOTE 5. Have debugged intense, and don't understand why this fails.
      • Test 1-4,6-11 OK
    • PAGING - Version: C00 - 1986-10-16 (Detected MMS-2 in ND-110 mode)
      • Fails almost all tests, loops with "Page Fault" during FETCH. MMS-2 must be different from MMS-1 on Trap
