I'm using MOCA here in my house, it's been a game changer. Beats wifi

If all you've got is coaxial cable and you really can't change it (such as if you're renting ... and your name isn't Cameron Gray) then MoCA gets the job done. I used it for a few months at this house when we first moved in, just to get the home office plugged in until I could pull ethernet. Wifi was pretty unusable as a daily driver.

MOCA works extremely well. especially if you already have coax in all your bedrooms (old houses).

It does, and as I mentioned earlier I think the people who make the hardware missed an opportunity by not making MoCA adapters that attach directly to the computer without Ethernet in between. Now that wireless has taken over everything and home Ethernet is pretty much the domain of the hardcore, that opportunity has probably come and gone.

They did.  But never saw them outside of a few targeted markets.

We used them at Ford in the plants.

Speaking of moca i have it running from my computer room to my "closet"  ( mentioned it before. Last year upgraded speeds. I cant use a WiFi bridge reliably due to interference, plus i cant get 1G wifi.. ).

This morning, noticed both changed IP addresses..   how odd.   Even during power outages they have never done that.

Cool. Now that Zilog is killing off the Z80 after a couple of centuries ( ok, exaggerating, slightly )  there is a project to release an open source version, on silicon. A 1:1 pin compatible replacement.  Using a 'seed studio' like place, except they do chips, not boards.  

Long live the Z80!

Cool. Has this project been blessed by Zilog or are they going to sueball it out of existence?

I sure do wish I had known just a little more about Z80 assembly when I was mucking about with my S-100 system back in the mid 1980s.

Not been blessed.  But, they have not sued any other z80 FPGA or emulation project..  I doubt they will this.    Besides patents run out after a couple of decades, so that angle is over anyway.  They could force a name change.. but that wont kill the project. "we renamed to Zeta80"

Assembly is where i started. With blinking lights and slide switches.  ( slide as they were cheaper than toggle.. i was a kid.. )

And speaking of old architectures, i loved the 8031 series.   It separated program space from data memory, in hardware.  Just made sense to me.

I still have the last board i built with it on there, well never finished it but was mostly done.   useless in the bigger picture but it still means something to me. 

Back when i was still into that sort of thing, i was designing CPU architectures.  Would use the boards to 'emulate' the processor, and the pin layout of a real thing so it was 'like it was real'. Never expected to be able to build it, but liked designing that stuff, and was hoping someday perhaps id get to work in that field when i grew up.    Did a few in discrete logic. then realized i could use EEprom's to reduce the parts count *dramatically*. Most logic is just a 'Karnaugh map' anyway, so its easily reproducible in a ROM..  Perhaps not as fast as real gates, but the tradeoff was more than acceptable. Reduced chip count AND easy to fix, or change.    Sort of an early FPGA, in a way. But then after that "why not do it in code and use the i/o ports like they were the real thing.... "

And since its 'pix or it didnt happen', the last board, 1987 ish..:

Mostly wired, ( other 1/2 is on the back side of the board ) but is missing the serial port driver chip.  And yes, i stacked those 2 chips ( 32k ). Another short cut. Id find chips with the same pin out, piggyback them other than the chip select. Tho often times id use a socket on top, so could easily remove the EEProm and reprogram it )  Which one was active is driven off those 2 smaller TTL gates, based on address decoding. Didn't do piggyback if i was doing an official PCB to put out in the plant or something.  This was just for dev work.

 

 

Fun times.  Different world today.

8031s ( and their siblings ) were hugely popular embedded chips and all over the place back then. Much like the ESP32 is today.

Grr make that Eprom not EEprom.  typo.

I dont think EEproms existed yet. We still had to use ultraviolet light to erase them.    ( i might even have my eraser around in a box somewhere..   donno )
