Zilog could get a bigger market share.
Still remember those times programming in Z80 machine code. It was much more flexible and convenient versus 8080.
You can find Zilog in embedded systems, they are not dead at all.
A few issues with DIY Alarm system to think about:
- no ESD (high voltage impulse) protection
- reliable power source
- compatibility with external centralized security systems protocols
I guess in every country any kind of monopoly leads to inflated prices and stagnation. We also have so many outdated and cost ineffective security systems here.
From the grid? See below. On the inputs? No, you're right.
> reliable power source
Not included in this post, because I'm not done with it yet, is the backup battery. The entire system runs on a 7.2Ah leaf-acid battery, which is connected to an electronic charger. So the alarm system power is isolated from the mains. I'm going to document this later in the series, when I'm all done :)
> compatibility with external centralized security systems protocols
I didn't really consider this, but it's easy to add if needed. Any examples?
This document specifies a new URI scheme called http+srv which uses a DNS SRV lookup to locate a HTTP server. The http+srv scheme operates in the same way as an http scheme but instead of the normal DNS A record lookup that a http scheme would use, it uses an DNS SRV lookup. This memo also defines a https+srv scheme that operates in the same was a an https URI but uses DNS SRV lookups.
