## Project Status
-### Revision 2.2 is the current production board.
-This revision adds a TICK header with three options for generating a TICK signal.
-
-**Hardware Supported**: All Amiga 2000 specific and Amiga general hardware is supported. The only exception would be external video hardware that would rely on signals not supplied on the HD15 video connection (see [Video](#video)). Here is a list of hardware tested and known to work:
-1. A2630 68030 CPU Card
-2. Supra WordSYNC SCSI Controller
-3. A2090 SCSI Controller
-4. Vampire V2+
-5. PiStorm
-6. RGB2HDMI
-7. BuddhaIDE
-8. GottaGoFastRam2000
-9. Wireless keyboard adapter
-10. A2286AT Bridgeboard (on ISA: SnarkBarker (soundblaster clone), XT-CF Lite and TsengLabs ET4000AX)
