Identify ][ - Automatic Hardware Detection

Identify ][ is a simple tool that let's you scan and analyse any of the computers of the Apple II family in less than 20 seconds and gain some insight in installed features. Emulators are supported as well.

Thx to Daniel Henderson's and Joel McWilliam's comprehensive beta testing we are able to release the latest version V.2.10 of Identify ][ into the wild.

What's new?

  • V.2.10: New hardware and features

    • Detection of empty slots versus unidentified cards (empty slots in previous versions were displayed as not identified)
    • Separate detection of SLOT AUX versus SLOT 3 on Apple //e or better. Normally SLOT AUX is populated with an 80-column card and hence SLOT 3 ROM space is double assigned - possibly to another card like e.g. a clock card. This version detects if there is an additional card in SLOT 3 besides an 80-column card in SLOT AUX.
    • New tiny tool SLOTSUCKER which reads the ROM space of a card and saves it to a file on disk. Great tool for retrieving ROM information of cards that are not yet identified by ID2! Suck the ROM information to a file on disk and send it to me, so that I can analyze the ROM data and add your card to the next version of ID2! Just type "RUN SLOTSUCKER" from the command line!
    • New hardware:

      • Apple2-IO-RPi Card
      • BOOTi Card
      • RamFactor Card

  • New hardware added (V.2.03):  RamExpress for Apple IIc, Videx 80 column-card
  • BugFix (V.2.02): The Saturn Card detection code lead to an unwanted "flying" disk write on Disk II controllers and connected drives to it. Hence booting the tool from floppy disk lead to a destruction of a disk track and leaving the disk partially unreadable and destroying the program on disk. Other drive types, floppy emulators or emulators itself were not affected only Disk II controller. This bug has been fixed now in V.2.02. Detects now a VidHD-card.


V.2.10: Download a DSK-image (DOS 3.3) or this DSK-image (ProDOS) of the new Identify ][ automatic hardware detection tool for the Apple ][ family of computers.

Hint: Users with an Integer Basic machine should just type "BRUN HWDETECT" after booting and getting an error when trying to run the AppleSoft startup program. The hardware detection tool can be run directly from the command line. Sorry, SLOTSUCKER is not available in Integer Basic yet.


  • Machine detection
  • CPU detection
  • RAM detection (supports: RamWorks and Saturn memory expansion boards as well as Language Card detection)
  • Screen refresh rate detection
  • FastChip //e and ZIPChip detection
  • Emulator detection
  • Joystick detection
  • Z80 detection
  • Slot scanning and identification of known interface cards
  • Empty slot detection
  • AUX RAM and SLOT 3 ROM scanning on Apple //e, //c and IIgs

Known Limitations:

  • No RAM-disk support yet (to be included)
  • No detection of modern video cards or monitors
  • No detection of TransWarp GS and ZIPgsx yet (to be included)
  • A Saturn Card in Slot #0 can mess up correct RAM detection
  • No detection of Apple II clones yet (to be included)
  • And a lot of not yet known side effects and bugs...

If you have any information on how to detect a certain card or if something is missing or not working properly on your setup please let me know!
