Learnt lots of good life and IT lessons at that job. 20 years ago I jumped to validating my query statements, rather than “beginning at the beginning”
so did you also get a S25 too, how do you like it ?
WTF is an S25? I do have an S-100...
I managed to blow up my linux today being stupid. Also managed to fix it - lesson learned...

you must not of read the entire post he made.
The new phone, a Samsung S25, set up and transferred easily. Winning!
When talking about computers, @Zorba probably won't consider a PHOOOOOONNE as a real computer, and an S25 (25-pin bus) would only be a really wimpy 4-bit backplane. An S-100 bus computer is a real machine, usually Intel 8080 or Z80 based. I was more of a sixer, an SS-50 guy, for 6800 / 6809 processors. But that's all from back when computers burned coal.

The days of iron men and wooden computers! I never messed with SS-50, I actually only ever saw one once. But I wire wrapped a 6808 system, and dearly LOVED the 6809 - my fave 8 bit processor by far. I also wrote a small amount of 4 bit code - 4004/4040. Harvard architecture - very interesting.
Decent enough processor for what it is, but no keyboard, no pointing device, a completely useless tiny tiny tiny screen, and a brain dead operating system takes it out of the "computer" realm and makes it merely a (crippled) "device". My new system, which costs about the same as most people's PHOOOOOONNEs apparently do (~$1K), will blow any PHOOOOOONNE out of the water, will last 10 to 15 years, and can do far more and do it far easier.
With that said, I know of people who are using PHOOOOOONNEs as fantastic embedded controllers for remote science equipment. Install Linux on the thing, it has lots of processing power and memory for such use, is easy on the power budget esp. when the screen is shut off, and in many circumstances can telemeter data back home via the cell MODEM. The small size becomes an asset. Who cares what the screen size is - you're not using it much anyway. SSH into the thing from a real computer, and Bob's your uncle!
Sorry @Zorba - the S25 is a Phooooone...a Galaxy S25. Android kinda sucks, but it's not Apple.
It's useful for taking pictures / astrophotography, and provides internet access for my 2 in1 laptop. SMS is handy to communicate with the spousal unit and the daughters as required.

Thinking about this - it might be possible to use an 8085 on a 25 pin bus as it muxes the lower address with the data lines. Just shooting from the hip, address/data takes 16, leaving 8 for clock, M1, IO/mem*, you could combine the 8085's RD* and WR* into a RD/WR* combination. Of course power and ground are gonna take at least 2 pins, you might be able to get away with leaving reset* off the bus, etc. Maybe you don't need HLD or HLDA... Just a thought exercise...
Yea, Android sucks, and Apple sucks more. I've used my flip as a hotspot a time or two when our main Internet went down. Expensive, but I can make 2 or 3 email runs a day without running the data bill up too much. I turned off SMS, its been ruined by everyone wanting to have lengthy conversations with it, and businesses wanting to conduct business over it which is HIGHLY unprofessional as far as I'm concerned. It was great for short one-off messages like "I'm running late, will arrive at ____", or "Pick up some milk while you're out" - but when idiots wanted to use it to replace email, and I started getting SPAMmed by it, I told my wife "I'm not paying for this bullshit", turned it off and pocketed the savings. I sharply dislike its push style notifications anyway.
I've got a few 8085s laying around. I've almost started to build something with them several times, but it may never happen.
Back when you needed dozens of RAM chips and several ROMs on a separate memory board, you needed all 16 address lines on the bus. But with more modern high density SRAMs, you can use one ROM and one RAM chip on the CPU board, and get by with just a few address lines for the I/O cards on the bus. I built a 6809 system with a 40-pin bus with 26 actual signal lines and the rest for ground and +5V. Some day I'll get the OS finished...
What OS? OS-9? Home grown?
There are several 1 board wonders with various processors on them, an 8080 and an 1802 come to mind, I'm pretty sure there are others. The board is scarcely larger than the processor itself, yet has all the RAM/ROM and I/O already on it. I'm tempted by the 1802, it was one of about two processors from that era that I never touched, the other one being the 8008.
Not to hijack the thread, but I sensed a bit of a nerdgasm happening here and thought you guys might get a kick out of this.
I got on a tear a month or so ago about cleaning out and up my life. From paper files/records, computer files, tools, gun cabinet, linen closet, refrigerator, the garage...you name it, I've torn into it and cleaned out a lot of old shit and unused items. Anyway, was going through a box of computer cables/parts last weekend and found these...
With exception to the 386, all were from workstations I built at one point or another, The Pentium II was actually a dual processor machine. No idea why I kept them but thought it was a cool little stroll down technology lane finding them.
Edit: Actually, I don't think that 486 is from my build...that would have been a 486DX2-66 (with 4MB or RAM - later upgraded to 8 - and a 250MB HDD. Feel the power!). Must have lost that one over the last few decades...

Home-grown OS, mostly ported from a 6803 OS I found online. I had it working pretty well, about 95% complete, when something went awry. I started debugging it, but that's time consuming on an unfinished system, and life got in the way.
I've seen some of those tiny-board machines, but can't really get interested enough to work with those designs. I missed the 1802. Sometimes I think about building one, but there are so many other CPUs that I actually like. Strangely I never built a Z-80 system, but I bought a few new-old ones from China recently.
Wow, you should come here and clean out my junk room. I'm sure you could make an exact duplicate set of processors here. Some are on boards which would actually run in the capacitors aren't shot. When I'm gone, my kids are going to hate me for leaving them so many tons of junk to haul away.

Ah yes, the Capacitor Plague that ran for years.
Ended up costing manufacturers hundreds of millions when they thought they were saving a few cents on capacitors.
Dell and Apple were very hard hit.
All due to a bit of corporate espionage that didn't work out.
And to the oldie stuff, I recently cleaned out some stuff myself and drug out an old box I had built who knows when.
It has an Athlon II X4 630 CPU, so I'm guessing ~2010.
Plugged it in and it fired right up into Linux.
Still a highly secure box since the password was (luckily) written on a discrete sticker.
Yea, the 1802 is kind of odd to someone like me who has never worked with one.
Do you have single step capability on your '09 system?
