Here's the Hackaday link to the project Z80-MBC2: 4ICs homemade Z80 computer | Hackaday.io[^].
Quote: The MCU Atmega32A is used as universal I/O subsystem, as Eeprom, and as reset and 4/8MHz clock generator for the Z80 CPU.
Inside the Atmega32A it is flashed an Arduino bootloader taken from here, and it is possible to use the Board Manager of the Arduino IDE to "import" it.

I bought the board and am soldering components, a lot of the are on order so it will be a while before I can update.
raddevus wrote: Is it just a serial interface?
There is a community that offers other boards for this chip/board but I'm at an early stage so if I can get it running on serial I'll be happy and then go from there.
raddevus wrote: Is there a hardware programmer with USB interface?
I have a hardware programmer to program the ATMega32A, I work with Atmel devices a lot. I use an USBTiny programmer but clones are very cheap on Fleabay. USBTiny USBtinyISP AVR ISP programmer for Arduino bootloader Meag2560 uno r3 711331264374 | eBay[^]

If you really need it, and can find an old 8" floppy drive somewhere, I can hook you up with a PL/I compiler for CP/M.

Thanks, appreciate it I'll keep that in mind!
It's been 6 months since I joined the gym and there's been no progress. I'm going there tomorrow in person to find out what's really going on!

Worked with it some when I first started computing, back in the dark ages.
I loved programming them back then and thought it would be fun to do some assembly and maybe even (shudder) some basic.

I'm more a 6502 type, the Z80 powered the Sinclair line of home PC's I was more a Commodore type...
Played with 6502 assembler back in college. Went from there to PIC...

Got the Commodore in early 80s, loved that machine. Wrote a sprite editor in assembler.
Had a lot of problems with the tape drive, could never get it to work reliably.

I guessed you would be a US native, this side O' the pond you were either a Sinclair or a Commodore they had big battle for the bedrooms. I went '64 as most of friends had one. The tape drive was an art form all it's own

Thanks for the recommendation! I bought and finished the ebook. I didn't know Bob Noyce of Intel, together with Jack Kilby, was the integrated circuit inventor.
I was also from electronics school. All my classmates were reluctant in it because their grades did not meet the cutoff points of their choice course. I enrolled in electronics because I wanted to be an inventor like Thomas Edison. That was before I knew of his bad reputation. I was not good on hands-on activities like soldering and wiring, so I transitioned to a software development job in the end.
Good that George Boole and Claude Shannon are mentioned. It makes me want to learn boolean algebra and information theory.
I was the one who gave you a 5 for this recommendation.

Glad you enjoyed the book. I am really enjoying the book too -- almost done.

I'm not great at it either but I really like working on electronics projects for something different (than software).

I'm like that too. I read about something and an author makes it sound interesting and off I go to read about the other thing.
There's a really great (recent) book on Claude Shannon: A Mind at Play: How Claude Shannon Invented the Information Age, Jimmy Soni, Rob Goodman, eBook - Amazon.com[^]
It's another really well-written and interesting book.

Any bullets? Fortunately I got only few.
Hellboy - I was one more random fan expected to see Hellboy 3. It didn't happen. But instead got this 
Glass - Split was good. It increased unbreakable expectations & forced me to watch this. Disappointed
Rambo: Last Blood - This one actually expected bullet. It was only available movie at that showtime during our unplanned visit to nearby mall. I liked the previous movie(Rambo) for action sequences.

Yeah it didn't look very appealing. Really like Judy Dench (sp.) though.

Mr. Cage survived being shot down in a prisoner transport plane, and then survived a terrorist organization on, "The Rock." Give the man a break; he's had it rough.

Per the immediately previous post[^] I have by way of contrast:
Yesterday I went into the yard to do some electrical work. The sun was shining as brightly as it can this time of year for this latitude (NYC area). I found it too warm and proceeded to work shirtless. Almost mid-January, too. Quite amazing.

Florida? If I didn't know better, and perhaps I don't, I would almost imagine you were gloating.
