restoring old asic

[NTMining]

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.

I *think* it's an Innosilicon A2BOX Scrypt Miner So it's for altcoin mining not BTC mining.
Looking here it looks a lot like this:
https://cryptomining-blog.com/2913-review-of-the-86-mhs-a2box-innosilicon-a2-based-scrypt-asic-miner/

BUT BEFORE THE MODS MOVE THIS....
A lot of the older Innosilicon stuff looks very very similar since they made 1 case and ran with it for a lot of their miners. There were a ton in the China market.

I know they had a BTC miner that was in the *exact same case* As my LTC miner I had both. Side by side you could not tell which was which. There was no external difference between the BTC miner and the LTC miner.
Are there any markings at all on the boards?

Edit to add: Either way, it's so old unless you have free power it's going to loose you money to run it.

@Dave, small fix.

It's actually A2 Terminator, the first scrypt ASIC miner Innosilicon has manufactured.
Here is some guide from Eastshore (which is a reseller company, still alive today):

Also maybe Innosilicon personnel still know things about it.
I don't know if they still answer questions about it.
Maybe they could send you a manual .pdf if they have one.
www.innosilicon.com is their web site.

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 https://lh3.googleusercontent.com/pw/AM-JKLW6MOaJcZcU2GJbBDJwh0KvVxr6q9aAZyy0UNTZhvG0tjzht7bKL5oAAFOR1GS0hezlP2zwSMVXt4ri66iP0Siq-H7tu6GwM4StTro-qZqAVqhYmAWrJ_8B6HIz1oxv0MScl6B5W54sS1HHNOqLhCjvhQ=w1266-h1688-no?authuser=0

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.

You can take a look here for a new / custom firmware: https://bitcointalk.org/index.php?topic=672969.0
Some of the links to mega do work. I might have an old one buried someplace but it would require digging thought some old drives to find so it might take a while....
