Printer manufacturers tried this several years ago with chips in ink cartridges. The supreme court ruled it was ok to reverse engineer the code on these chips if it was required to allow other companies to make make compatible cartidges. I would think the same would apply to cars and after market parts and upgrades.

The video produced by the Apple II is not interlaced at all. Many video devices used to mix and overlay video in studios had trouble with this fact. True the video memory is not sequential but that's not the same thing as interlacing. Way back in 1983 I had lunch with Woz and a half dozen or so mostly game developers at the Independent Developrs conference. I asked him if he would want to change anything about the design of the II. He said he might add the two chips needed to make the video memory map sequential. Several of us including myself said that most of us would still use a lookup tables for updating video memory anyway (it was faster) and that didn't really matter much. In the end he agreed.

As far as the 6502 being the shittiest processor of it's generation I would have to disagree. True it has fewer registers and instructions (RISC?) than most even older designs like the 8080, but it did have some unique adressing modes that made it the perfect processor for the graphics the Apple did. This coupled with the fact you can use the 256 bytes of zero page much faster and much like processor registers (indexed memory referencing) made it one neat machine.

I bought a bunch of model M's a few years ago at the Miami Hamfest. Payed $3 each for them. Still have about 8 of them. Been using them ever since. My wife Lesley who is a touch typest at around 70/80 words per minute loves hers. Newer machine require a USB adapter thats cost around $5 but they all still work great. I play CounterStrike, TF2 and Mech Warrior Online with mine.

It's true that my system has been somewhat upgraded. The GPU is faster than anything I could have gotten in 2006 (maybe twice the speed). Still that a basic system could still be viable after 8 years is unprecidented. I would have been nuts to be using a computer built in 1986 (386 16MHz) in 1994 (486 100MHz) or a system bult in 1996 (Pentium 133MHz) in 2004 (2.4GHz P4). These improvements have been on the order of 10X or more over 8 years. Performance gains since then have maybe been double, a big slowdown.

I'm not sure where all these extra transistors are being used but it doesn't seem to have enhanced overall system performnace to nearly the degree it did in the past.

I have been in computers since the very early 80's starting with an Apple II. From then to about 2008 I have aquired or upgraded my computer about every 3 years or less. I am currently using a machine that is over 8 years old. Quad core Dell Precision 390. Still performs well enough to play modern game titles like Mech Warrior online. At no previous time could I say I would be satisfied using an 8 year old computer. Moores law has slowed to a crawl compared to what it was doing in the 90's. So a 12 years old computer today is closer to modern perfomance that at any time I can remember.

Plenty of companies do. This is standard Operating procedure for ISP's and online services. Google, Facebook, Ebay all do. If your server needs to be accessible from the public Internet then yes. Firewalls are overrated as a protection measure. If you can run them from behind a firewall then I see no reason not to unless you have to open a bunch of ports to allow access to the server in which case the firewall won't help much. This is usually port 80 and it's where most of your attacks will come from anyway.

If only a select group of people will be accessing this server from the Internet then the safest way may be to make it accessible only via VPN. Users would have to log into the VPN first. Much stronger protection than a server behind a firewall with ports open.
