A2000-Motherboard im E-ATX-Formfaktor: Tests des Amiga-2000-ATX-Prototypen
After developer 'jasonsbeer' received the commissioned prototype of his replica of the A2000 motherboard in ATX form factor, 'Amiga-2000-ATX', a few days ago, he is now testing it for functionality and possible bugs. He writes:

"Over the last two days, I have been able to confirm that the Zorro 2 bus and coprocessor slot are working. I am currently using a Supra Wordsync SCSI card, a Commodore A2630 accelerator and a Pi HDMI video card. AIBB is on the screen. I have run the Amiga 2000 EATX for several hours without a single problem. I have tested both an Amiga floppy drive and a Gotek floppy emulator with great success. The keyboard is connected and works fine (with a tweak). The mouse and joystick connections work as expected. The only things left to test are the parallel port and the real-time clock.

As a side note, there is an error in the schematics of the Amiga 2000 that relates to the pin numbers of the keyboard ports. They are mirrored on the schematics of the A2000 and A3000, hence my workaround for solving this keyboard problem." (dr)
