Atari 520ST, 1040ST, Mega 1/2/4, Stacy, 1040STE, MegaSTE, TT and Falcon Computer Diagnostic Loop Test Hardware Test Kit
When Atari set up a new US Atari ST Service Center Dealer, as part of the ST Dealer Service Center package (full set of ST Computer repair Manuals, ST Color and Monochrome Monitor manuals, 520ST/1040ST Diagnostic Cartridge), a new complete 520ST, (later) 520STFM and 1040ST Computers for parts) and this loop back ST Test kit. The new Atari ST Dealer paid for ($,$$$+) for this complete Atari Service Center Hardware Package.
This Atari ST Loop back test hardware is used with the many different Atari ST different Diagnostic Cartridges (520ST/1040ST/Mega, Stacy, 1040STE, MegaSTE, TT or Falcon Diagnostic Cartridges) to fully test all ST computer Internal and External hardware functions. Extra port shorting hardware / plugs required for the 1040STE, MegaSTE, TT and Falcon computers to full run all of the extra Diagnostic Tests / Ports (extra features or different style ports of those model Atari computers).
The two DB-9 black Joystick cables are connected up to the ST Joystick/Mouse ports and back to the Loopback green PCB (most ST computers require you to crisis cross (not one to one) these DB-9 shorting cables back to the loop back PCB to get the proper port diagnostic results). The short black or gray DB-25 Parallel cable is connected to the ST printer port and loop backboard. The short gray ST DB-19 DMA cable is connected to the ST DMA port and the loop backboard. The 5 pin Din shorting cable is connected up to both ST Midi Ports (one end of this Midi cable has a Red LED molded into the translucent connector housing to see the Diagnostic Midi Send and Receive sent signals). The DB-25 Serial port shorting connector is connected to the ST Modem / RS232 external Port.
Depending on the exact version Atari ST Diagnostic Cartridge used with the ST loop back hardware test board, you can choose from the ST Diagnostic display menu to run between different ST Diagnostic tests one at a time or our 27+ year Atari Super Tech’s standard 12 to 24+ hour continues Burn in loop that he tests all ST computers with. Typical Atari ST Diagnostic tests you can run using the different Atari ST Diagnostic Cartridges and Loop back external Hardware, upon boot up displays ST TOS Rev., Total ST / TT Fast Ram, Keyboard I.C. Rev. level., 5 ST Ram Tests, 7 ST internal Chip set timing Tests, if present 14 Blitter chip tests, if present 2 Real Time Clock tests, Audio tests, OS ROM Test, 2 Printer Port I/O Tests, Color and Monochrome ST display tests, 3 Keyboard tests, 5 Mouse and Joystick port tests, 12 RS232 / Serial / Modem I/O port tests, 50 / 60 Hz display toggle, 17 Internal or External Floppy Disk Drives tests, 4 DMA I/O port Tests, 2 Parallel port I/O tests, 5 Midi Send and Receive Tests. The best way to fully test and burn in any unknown condition or repaired Atari ST computer.

Atari Tech Tip on the Loopback ST PCB board. Our Atari Super Tech strongly recommends you tape the anti Static pink bubble bag the Loopback board comes in (or tape a piece of thick and oversized piece of cardboard) to the exposed back side / solder side of the Loopback PCB board, to prevent it from shorting out / damaging the different I.C.’s on the top side of Loop back PCB should the back side of the exposed PCB come in contact with any metal.
