Did you have a computer with a #Z80 processor?
Mine was a #MSX Philips VG-8020.
I'd love to know what yours was.

I love seeing so many people on Mastodon who had a computer with a #Z80.
Did you have one too, @rc2014 ?
Show threadRC2014Apr 26, 2023
@agonzalez I didn't have one... I had a few!
48k Sinclair Spectrum was my first though, but I've had (and still have) many Sinclair machines, as well as Jupiter Ace, Cambridge Z88, Amstrad PCW9512, MicroProfessor and probably a few more :)

@lopta @agonzalez
If you mean my Z80 thing ? No it's just "a bus I invented" more or less "as the signals were coming out". It has some "extra stuff" as that among things that CPLD does a bit of "Memory mapping" adding 5 more extra AD lines plus has a concept on "On board mem/IO" and "Off board mem/IO" to allow me to address extra memory/IO well over the 64K limit. In fact there are 256K or ram in that board and I can map it in segments.

@agonzalez muy first computer was a #MSX Sony HB-75P, these days I still have a Panasonic FS-A1WSX which had a 220V PSU swap and a 256 KiB RAM upgrade done when it was brought in the 90s to Spain by a professional importer.

@agonzalez this is my current project. A Cifer 1887 which has four (count 'em) Z80A processors. One for the Processor board, one for the Disc Controller, one for the Graphics board and one for the SASI interface. Oh, and there's a Motorola 68000 add-on board too. Is that enough? 🤔😁

Runs CP/M and can (in theory) run Unix System III.

@agonzalez I had 2 MSX: a Canon V-20 and a Spectravideo 738. The Sony F1XD is a recent acquisition.

Also, I have a Sanyo MSX2+, my favorite one, bought when I was in high school.

@agonzalez Good old Spectrum. Learned machine code on it and used to hand assemble my routines. Took an age but they worked. Stood me in good stead for my career in electronics as I used Z8's extensively.

@agonzalez While I started with a ZX Spectrum in 1983 as a kid, my main #Z80 computer is the SAM Coupé - I bought my first in 1993 and immediately started programming on it.

Thirty years on, I still develop for the SAM Coupe having released a wealth of hardware, software and magazines over the years.
