ND-250247 — ND-5000 Test Microprograms

Status: DIRECTORY LISTING ONLY — no floppy image located

Field	Value
ND article number	ND-250247
Directory name	250247A00-XX-01D (revision A00, one diskette)
Product name	ND-5000 Test Microprograms
Functional category	Hardware test / diagnostics for the ND-5000 (SAMSON) CPU

What is known

The diskette's own directory listing survives — see ND-250247A-Software-Library-Diskette-Listing.md. It holds 20 files using 263 of 610 reserved pages, owned by FLOPPY-USER:

• TPF-MON-100-A04 (PROG) — the test program monitor that runs on the ND-100 side
• SEMICS-1-A00 (TEST) plus SEMICS-2-A00 / SEMICS-3-A00 (NEXT continuation files)
• Per-block EXT tests, which map one-to-one onto the SAMSON block diagram: ALU-VERIFY, ALU-CARD, MIC-REGISTER, MIC-SEQUENCE, CACHE-TEST, IAC-TEST, DAC-TEST, IDU-REGISTER, IDA-VERIFY, DMM-REGISTER, IMM-REGISTER, MM-VERIFY, AAP1-2-TEST, AAP2-VERIFY
• Two MODE install files: INST-SEMICS-A00, INST-EXT-A00

The block abbreviations (IAC, DAC, DMM, IMM, MIC, AAP, ...) are the ones defined in the SAMSON design document — see ../../../Reference-Manuals/500/ND-SAMSON-1-EN SAMSON Expected Behaviour.md.

What is NOT known

• No floppy image for this article number has been located, so the programs themselves are absent.
• The install procedure is not documented here; it lives in the two MODE files on the diskette.
