My finished project: A1200 Digital Edition
I haven't owned any real Amiga hardware for 15 years, since I very regretably sold my A1200 modded with DVD drive. Since then, the world has mostly moved on from physical media; my new gaming PC has no mechanical drives and is entirely solid state, as are my two PS5 Digital Editions, both with expanded SSD storage. So inspired by this, I decided that my new A1200 project for 2023 was to create an A1200 Digital Edition.
My 6 goals were:
On the second attached photo: 1. ATX cable soldered to power supply pins on underside of A1200 motherboard, keeping original power socket intact and working (as a backup). 2. External power socket for PicoPSU (takes a 2.5/5.5mm connector from a standard 12v laptop charger). Deliberately placed above legacy power socket to avoid accidentally using both! 3. Power switch (rocker switch) for PicoPSU 4. 16GB compact flash card (non-WHDLoad games) 5. Gayle adapter for 4 way clockport expander 6. 4 way clockport expander 7. A1200 real-time clock 8. Kickstart 3.2.1 ROMs (redundant, system uses 3.2.2 ROM flashed to Vampire V2 V1200 core) 9. 32GB compact flash card (AmigaOS 3.2.2, programs, WHDLoad games, music, videos, demos) 10. Indivision AGA Mk3 mainboard 11. Indivision AGA Mk3 keyboard adapter 12. New longer keyboard ribbon cable going to new hard keyboard membrane 13. HDMI connector bolted to case through shielding, for Indivision AGA Mk3 output 14. PicoPSU-90 internal power supply (90W max) 15. HDMI cable 16. Subway 2021 USB card 17. Vampire V2 V1200 (85Mhz 68080 accelerator with 128MB Fast RAM and RTG) flashed with 2.16 Gold x12 core 18. Vampire ethernet module 19. SD card slot extension cable 20. Flat HDMI extender 21. Floppy drive terminator 22. USB 2.0 Pin Header cable 23. OmniPort Vampire 2 multiport (2x USB, Ethernet, and HDMI output for Vampire V2 V1200) 24. SD card slot (in space of floppy eject button) 25. Indivision AGA Mk3 HDMI/VGA connector The "problem" of two HDMI outputs (RTG and AGA) is easily solved with a HDMI switch. For a joypad, I use a PS4 controller with mouSTer adapter. And last but definitely not least, the motherboard has had a full polymer recap. I realise it's not to everybody's tastes, but hope you like it or it inspires you to do your own project. |

I have the same hardware setup in a black case with black keyboard, except i don't use a picoPSU but the CA-PSU from IComp, and i have the Gayle adapter for a second clockport without the clockport expander. I don't call it my A1200 Digital Edition, but my Blackmiga 1200

There's a neat little solution that involves attaching a wire to either your CIA (iirc) or pin 13 of your parallel port from the HDMI switch internally. Then a small software stub sends a signal to the switch to automatically switch from RTG to RGB and back.
I have one in my 1200, it's wonderful. |

I updated my build a couple of weeks ago. Some people may have already seen it on one of the main Amiga Facebook groups. I had the opportunity to get a black A1200.net case and key caps and couldn't resist, and I've also added and changed a few other things such as a PiStorm32 Lite with Pi 4b, a PicoPSU adapter, and replacement LEDs:
I now call it my A1200 Midnight Edition:

https://www.amazon.co.uk/gp/product/B09LVDP7FL Then you open it up and solder a wire from pin 13 of your parallel port - I used a plug rather than solder directly to the Amiga - to a pin on the switch of the HDMI switcher: and another user who has also made one: Then grab the software from here: https://drive.google.com/file/d/16ok...ew?usp=sharing and use the external version, in your startup-sequence. (if you're on a PiStorm you don't need the software, the P96 card driver will do it for you). Boot with the switch set to RGB mode and when the RTG workbench activates it switches immediately to the correct input.
