What are some lower hash rate models for scrypt algo. Besides A4, L3 and titans.  Was there a 30/60 MHash/s A2?

The A2 had 2 varients that I know of, an 85MHs and a 110 MHs. Both rock solid rigs.
Not sure of others on the market except for the Gridseeds.

gridseed had a 25Mh/s miner

the gridseed g-black.

but can't seem to locate one... i've got one sitting on my shelf.   
around 400 watts i think

Ive gotta think the Zeus/GAW miners are probably not even gonna cover their electric expense.
The A2 is marginal return with electric factored in.
I think the Gridseed is still profitable, but just barely.

So, 30 Mhs @ 300W vs 250 Mhs @ 400W...
Think ill hold out for the L3...

What are some lower hash rate models for scrypt algo. Besides A4, L3 and titans.  Was there a 30/60 MHash/s A2?

Thanx!

 A2 "official" models were the 88 Mh/s and the 110 Mh/s - both rock solid except for the "original" 1100 watt PS being very marginal at best for the 110 Mhs models.
 The Seasonic X1250 Gold (and presumably the X1200 Platinum) is a VERY good replacement for a 110 with a dead PS, it fits nearly perfectly in place of the original PS and has plenty of power capasity.
 I have 1 of the 88 and 4 of the 110.

 There were 30 and 60 Mh/s A2 models, none of them were official from Innosilicon as I recall but appear to have been "cut down" from A2 88Mhs models presuming using spare controller interface boards from Innosilicon and usually in a custom case.

 There was also the "Farm Boy" model that WAS official from Innosilicon, but I do not remember the details on that one.
 Efficiency would be the same as the A2 as it used A2 chips.

 There was the Alcheminer, but that was 250 MH/s at near identical to A2 efficiency - there were also "OEM label" versions like the MAT of that one.

 Anything else that was lower hashrate than the 2 "main" A2 models was quite a bit lower efficiency than the A2 and is likely unprofitable unless you have VERY VERY cheap electric.

 Gridseeds are NOT profitable any more even at 3c/KWH electric - I've got some of those and did the calculation last week.
 They ALL used the same GC3355 chip, just different board configurations and similar efficiencies.

What you'll mostly see are gridseed miners from the old days- those all ran the GC3355 chip and were profitable up to this year. Pretty good considering how long ago they were designed. They can be found on a lot of sites like aliexpress but can also be found on the forum he if you're looking for a small setup.

 At 3c electric the GC3355 units were still profitable right up to about the turn of the year, when the diff exploded out of the 50-60k range.

 They'd STILL be profitable and might even ROI if you get them cheap enough, don't overclock them enough to kill the power regulator stuff, and have FREE electric.

Those A 2 were called farm boys, it  is three 33 MH A2  your right it was Innosilicon made my bad, it's not hard to make one, some one is Selling working PCB A2 boards on ebay, i forget the price . and claimed he has parts to make one . he based in Russia ....'

I also have a working Alcheminer ruining five boards with the firm ware fix ....using BFG ...with a custom controller.

The Alcheminer ran about the same as the A2 with more hash per board/blade. I mean is one Alcheminer blade does what two A2 blades do with about the same power usage ..to bad the Alcheminer 2 never happen it would have matched the L3 or close but the company went bankrupt after MAT miners ripped off a lot of people ..

 No, the 30 Mh/s and 60 MH/s units I was referencing PREdated the Farm Boy by quite a bit - they were around from various dealers (MAT and ZoomHash come immediately to mind) very shortly after Innosilicon released the original 88 Mh/s unit but BEFORE Innosilicon released the "Mega" 110 Mh/s unit.


 The "Farm boy" units were some sort of  a crossbreed between Zeus and Innosilicon, using A2 chips on a Zeus framework of some sort IIRC, and didn't show up 'till after Innosilicon was almost out of the 110 Mh/s units to sell.
