For me with the V2 shifter adaptor its a working product have been using it in anger playing games and other desktop app stuff.
Using V1 Shifter Board:
ST Model | Revision | Resetting | Shimmering without cap | Shimmering with 22pF | Comments |
520 STM | C070243 REV. E | Yes | No | No | Rock solid display can be seen if you can get it past resetting and playing a game. Setting PSU to 4.3V and the ST boots and doesn't reset but there isn't enough power to supply floppy but I could get Gigafile to operate |
520 STFM | C070789-001 REV. C | No | Yes | No | Shimmering even present playing a game. Adding 22pF cap stops the shimmering |
1024 STFM | C070789-001 REV. C | No | Yes | No | Shimmering even present playing a game. Adding 22pF cap stops the shimmering |
520 STFM | C103253 REV. 3 (C103088 REV. 5) | No | Yes | No | Shimmering even present playing a game. Adding 22pF cap stops the shimmering. Quite often starts with colours out of phase |
STF Remake | C070789-001 REV. F | Yes | No | No | Revision is from the donor STFM that gave the remake most of its parts. Seems to exhibit same behaviour as 520ST including dropping the voltage. |

1024 STFM | C070789-001 REV. C | No | No | Perfect no resets or shimmers |
520 STFM | C103253 REV. 3 (C103088 REV. 5) | No | No | Perfect no resets or shimmers |
