One system, three jobs

MODE 01 // BUY

Inspect the machine

Run a ten-minute seller check, score the condition, price identified repairs, and know when to leave.

  • CompactFlash pin and load test
  • Pad soft-to-hard strike test
  • Controls, outputs, boot and display
MODE 02 // BUILD

Upgrade in order

Fix session-stopping faults before buying a screen, shell, or another part that does not solve the problem.

  • JJOS decision map
  • Parts and budget worksheet
  • Pad, storage and RAM priorities
MODE 03 // TEST

Prove it in sessions

Record what changed, then force the machine through repeatable cold-boot, media, pad, audio, save and reload checks.

  • Bench change record
  • Two session reliability logs
  • Final completion card

FIT CHECK // READ BEFORE PURCHASE

Use it if

  • You are buying a used MPC1000.
  • You own one with an unknown service history.
  • You want a sane JJOS and upgrade decision.
  • You need repeatable proof that a repair worked.

Skip it if

  • You need a full disassembly or board-level service manual.
  • You want an MPC Live, One, X or Key workflow guide.
  • You want fixed marketplace prices that never change.
  • You are looking for a replacement for qualified mains repair.
