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.
