A batch file to get the file STARTRK and output it to the card punch
NOS (Network Operating System) is a discontinued operating system with time-sharing capabilities, written by Control Data Corporation in the 1970s.[1]
NOS ran on the 60-bitCDC 6000 series of mainframe computers and their successors. NOS replaced the earlier CDC Kronos operating system of the 1970s. NOS was intended to be the sole operating system for all CDC machines, a fact CDC promoted heavily. NOS was replaced with NOS/VE on the 64-bitCyber-180 systems in the mid-1980s.
Version 1 of NOS continued to be updated until about 1981; NOS version 2 was released early 1982.

› What is Bitcoin Mining? › Bitcoin Mining Software
Now that you already know about the best Bitcoin mining hardware, we’re going to talk about Bitcoin mining software.
What is Bitcoin Mining Software?
Bitcoin mining hardware handles the actual Bitcoin mining process, but:
Bitcoin mining software is equally as important.
- If you are a solo miner: the mining software connects your Bitcoin miner to the blockchain.
- If you mine with a pool: the software will connect you to your mining pool.
- If you are cloud mining: you do not need mining software.
Quick Tip
Mining is not the fastest way to get bitcoins.
Buying bitcoin is the fastest way.

Why Do You Need a Bitcoin Mining Operating System?
Bitcoin mining rigs and systems have come a long way since the beginning. The first Bitcoin miners made do with the tools they had at their disposal and set up various software to control the mining hardware in their rigs.
While these make-shift solutions were better than nothing, they didn’t exactly work efficiently. Not only did that slow down the mining process, but it also made it difficult for newcomers to join in on the fun.
Necessity is the mother of all invention, so along came solutions like Awesome Miner, ethOS, and SimpleMining that streamlined the mining process.
These days, mining operating systems are the standard.
But many users of the existing systems still experience issues with:
- Managing multiple mining devices.
- Maintaining a steady mining performance.
- Fixing spontaneous errors.
- Managing the mining system remotely.
- Maximizing the efficiency of their hardware.
Importance of Bitcoin Mining Software
The main job of the software is to deliver the mining hardware’s work to the rest of the Bitcoin network and to receive the completed work from other miners on the network.
Bitcoin mining software monitors this input and output of your miner while also displaying statistics such as the speed of your miner, hashrate, fan speed and the temperature.
You may also need Bitcoin tax software in order to calculate your taxes owed.
