thanks for the information, i followed up with innosilicon, as it looks like support for this model has been removed from their site. guess we will see what happens. would hate to part this out if it could be restored easily.

Hey Dave, thanks for the reply. Nothing special about the PI, the daughter board is unlabeled aside from basics such as fan 1, fan 2, atx 1, and mode connections nothing i can see regarding version or MFG date). honestly it looks pretty rough as glue or resin has been used to secure the connections from cable creep. as for the asic PCBs, I see 1T25 v1.2 printed clearly on the board 1412 is printed on the opposite corner and one of the easiest IC's to read shows STM32F103. VET6. x.  HPAKU. 93.  KOR. HP.  407  looks like thats an ARM CHIP.... most everything else is obscured by heat syncs

Hello, i was given an older mining rig by a friend who didn't know much about it. It has no identification on the chassis, at all, but inside I see it has a raspberry pi connected via GPIO to an unbranded / PCB that communicates with 6 1T25 v1.2 boards (guessing these are some sort of asic). There is no SD in the PI, i'm hoping to get some information on where to go for an OS so i can boot this up and investigate it. does any one know where I can find an OS for this? Or can anyone identify it? Almost seems like an old Dragon miner setup from the research i have done.
