The Macintosh was Steve's baby in all but the name (Jef Raskin contributed the name).
Steve Jobs joined the Macintosh project when he was forced out of the Lisa team. By that time, the hardware design was pretty much finished. Much of the software was inspired by the Lisa project (at least in what it looked like, but Jobs never wrote any code). The only thing that was purely "Steve" was the case. The Macintosh could have happened without him. To say that Woz was important early on is an understatement. He made the product. You can't start a company without something to sell. He quit Apple in 1987. He doesn't owe them anything.
PWRs are the "tried and tested" technology. 50 years has given us a pretty good understanding of how they work and how to handle them. Pebble bed reactors have had some issues with safety (not to say that PWRs haven't, they just haven't for a while and people have short memories). One of the biggest scares is that if air is allowed into a compromised reactor vessel, graphite pebbles will burn releasing radioactive particles in the smoke. The results of the AVR and THTR-300 reactors in Germany have also dampened interest in PBRs. Most progress will probably come from China. If they come up with a good design it may become more popular elsewhere.

Apple computer happened when Steve Jobs convinced Steve Wozniak that there was a market for his then unnamed 6502 computer with built in terminal. There may have been an Apple Computer without Woz, but it wouldn't be the Apple Computer we know. If that Apple Computer hadn't developed the Lisa, the GUI may have stayed in Xerox's closet for a lot longer. I don't know if C and UNIX would have happened without Dennis Ritchie, but they made a huge impact on the computer industry. Just about anything you do with a computer today involves something pioneered by UNIX and probably directly involves C. I can't imagine what a world without UNIX and C would be like.
They are and were all great men and who is the greatest is completely subjective, but one thing is for certain: the world could have been a lot different without just one of them.
They're using AP1000s. They're a modern form of the old pressurized water reactors developed in the 50's for nuclear submarines. Boring, but cheap and safe.
And this thing is not going to be powerful enough to run a normal web browser.
That's just because "normal" web browsers are abominations. Damn Small Linux can browse the web on a 486 with 16MB of ram. This thing is a monster by comparison.
Yeah, EPROMs are ancient. The only reason I can think to use them is sometimes you can find them cheap as free online. Blank OTP EPROMs are probably impossible to find and if you can find a blank bipolar PROM, donate it to a museum!
True, one socket will cover most (E)EPROMs, but if you really have to program every chip under the sun not messing with adaptors is worth a great deal. Putting a RAMDAC on every pin would be like driving a rocket car to work though. You could get the same functionality from analog multiplexors selecting from 0V, Vlogic, Vcc and Vpp.
The M27W401 is in the programming mode when VPP input is at 12.75V, G is at VIH and E is pulsed to VIL. The data to be programmed is applied to 8 bits in parallel to the data output pins. The levels required for the address and data inputs are TTL.
Ok, make the Vcc pin the same design as the Vpp pin.
Even some modern parts (Atmel AVR MCUs) support high voltage (12V) programming.
The only "high voltage" in AVRs and PICs is on the MCLR/Vpp pin. This is covered by the design of my Vpp pin. The STK500 just uses a fixed 12V.
Grab one of those battery powered closet fluorescent lights, one that takes a 6" tube. One with a DC jack is preferable so you don't go through batteries. I know you have a box full of adaptors somewhere. Find a germicidal UV tube*. If you can't find one at a hardware store you'll probably be able to find one at a plumbing shop, but it'll probably cost more there than here. Buy an egg timer if you don't have one. It should all be less than thirty bucks. Jam the UV tube in the light**. Leave the plastic window off when you put it back together, it might block UV light. Attach the light to to the lid of any old box, probably with the included Velcro stickies. Program an EPROM all zero and throw it in. Pull it out and check it every 5 minutes or so. Multiply the total time it took to erase by 1.5 and write it on your box.
Super ultra cheap bonus design: leave it out in the sun. Disadvantages: For one, the sun's UV intensity is lower than an actual UV bulb, so it takes longer. Expect 12 hour erases. Two: remember to keep checking it and put it away when it's erased. Leaving it out in bright sun for a week might hurt it.
*Warning! UV light is bad for your eyes! Don't turn it on and stare at it.
**Remember to properly recycle your florescent tubes, or like me keep it forever because there's nothing wrong with it.
That thing is like... the Monster Cable of programmers. This is old stuff so high/low will only be 0V and 5V. Slew rate has to be only one thing: faster than the most demanding part. Only one pin needs to source Icc: Vcc, and all it needs is a switch to +5V. Programming pulses are 0.5 or 50 milliseconds for CMOS and NMOS EPROMS. The most difficult pin is Vpp. Amplify a dac to 0 - 30V, buffer it with an emitter follower and switch between that, 5 and 0 volts. Just make sure the voltage is what the datasheet says it should be.
I very much doubt that there is a modern design that can reliably do what you need.
It's trivial to program EEPROMS. Finding an EEPROM programmer that can't reliably program EEPROMS would be like finding a coaster that can't reliably stop a coffee ring. And guess what? Flash is just EEPROM that you can't erase a byte at a time, so the technology isn't obsolete yet.

joocemann thinks fanboys doing "intellectual" battle over something as trivial as what OS your phone runs are pretty funny. I have to agree with him.

Hmmm... If you had a big enough SD card you could slap an PC emulator on it and thrash around. Probably take a month to boot though.

I'd argue that that's six orders of magnitude more hardware than you need.

This looks like what you're looking for: TOP853 Universal Programmer
Supports EPROMs, EEPROMs, some MCUs, PLDs and will even test SRAM for you.

You overestimate how trivial *PROM/PIC/AVR etc programmers are. I designed and built one in an afternoon.
I bought a USB/Serial adaptor on eBay for less than $4 shipped a while ago.
