The problem we are now facing is that this all requires some logistical problems to be solved. The most important one of which is that there are not one hundred thousand 1802 microprocessor chips on planet Earth. So we are working with a Chinese electronics manufacturing company who already has ties to Intersil to re-produce the CDP1802. This is good news for all 1802 hobbyists, because the chips will now be readily available at very affordable prices. (yes, customers will eventually see the savings reflected in product prices) And the good news on top of that is that, whilst we are re-producing the 1802, we are also going to re-produce the rarer than hens' teeth, Unobtainium CDP1861 Pixie display chip, and the other CDP18XX display and sound chips, so now those will also be available again. Also at very affordable prices. Expect new products to be available soon that will use these new-old chips. (no more pseudo-1861s) So the good news keeps getting better.
Jurassic Park is in Australia? They probably found mosquitos in amber, which had bitten CDP18XX chips and plan to extract the DNA? I will patiently wait to see where this goes. I think you can still order the CDP1802 as a high reliability processor at a horrendous price of about 200 bucks each, but that would probably be a little too expensive. If it must be an imitation, it should be a good one. White ceramic packages[^] and golden contacts. And you guys will get none of mine!
I have lived with several Zen masters - all of them were cats. His last invention was an evil Lasagna. It didn't kill anyone, and it actually tasted pretty good.

I never programmed the 1802, but I sort of long back to the days when you could follow every bit inside the machine, know where it was flowing, and why. You had full control. You knew what was happening. I started computer studies when 16-bit minis were the norm. The student lab got hold of a retired Nord-10 computer for our hobby projects, with super-fancy interrupt system, advanced memory management. We had full source listing of the OS; it was an interactive multiuser, real time OS, a full file system, yet only about 60K source lines. We could trace every system call. When I had something not working as explected, a fellow student asked in dead earnest: Have you single stepped through the microcode to trace what goes on? That was fully possible, but I think he was the only one doing it. Or: For a few weeks, during heavy construction work, disks had to be turned off at nighttime; they couldn't handle the vibrations. That didn't stop one student group developing a game: They loaded all their stuff into memory before the "Turn off disk" alarm went off, and replaced the interrupt handlers of the OS with their own, mimicking all the system services that their game required for running, so they could run a full memory resident system with disks turned off. Those were the days... Try to get anything even close to similar fingertip control with a latest-generation IA64 CPU. Not even with Linux will you know everything that is going on in the OS (oh, Linux guys will claim that it is poosible, but that is only in theory!); with Windows it is completely impossible. For a period, about 6-8 years ago, again I got the feeling of total control, when I programmed 8051 chips, with no OS support. (We made our own monitor.) When we switched to ARM chips, programming did become a lot easier, but it was the first move to again loose control. The monitor became far more complex; none of the developers can explain in detail more than their little corner of it. Now it is being replaced by a fullblown OS, mostly developed by others. For my hobby activities, I strive to reduce complexity, to keep control as much as possible. I won't go as far back as to the 1802, but playing around with Arduinos gives more satisfaction than fighting to understand WPF event routing. :-) So I can very well undertstand those who take the KISS principle literally, and go for 1802. Bonus chatter: When I was a boy, I din't pick apart alarm clocks, but (cheap) cameras. Then, $10 Instamatic 126-format cameras (which was all a ten year o

That sounds a lot like Chris' description of the CodeProject server cluster I read over 20 years ago. In fact, it sounds like someone is planning an upgrade!

CP turns 19 on 15-11-2018 Western Hemisphere dates, of course here the the more futuristic Eastern Hemisphere we're a day advanced. CP was born on my (Eastern Hemisphere date) 31st birthday. So a bits a maths should tell you how old I am in 20 days when our birthdays come around again.

I rounded up - so shoot me! ;P It still sounds like the original description of the server, though I think we were using obsolete palm pads or some such. The 1802s ought to be a huge improvement.
