Processors - Having somehow received mail from Moscow, I came across an interesting conversation, in my opinion, about the non-ZiLog processor Z8O, which in many respects is superior to its brother from the ZiLoG company...

                                                                
                                    
                                    
                                    
                                    
                                                                
                      ... Conversation ...

   Получив как-то метр почты с Москвы я наткнулся на интересный,
на  мой взгляд разговор, проходивший о не зилоговском процессоре
Z8O,  который по многим параметрам превосходит своего брата фирм
ZiLoG ...  Because  it was too long ago, it will probably be of interest to you

Goldstar is a good processor, it was used even in the old days - when machines
consisted of heaps of crap :) - for machines with a floppy drive specifically
They installed it because it is powerful in terms of tires. And it gets very hot ;)

In what test? What kind of computer do you have? Turbo mode was originally    
implemented on your computer?

I remember these GoldStars. Good guys. Appeared somewhere in 199O  
year. True, a friend has one                                   
it crashed on its own. :) And about disabling your computer... Apparently, this GoldStar      
has an increased load capacity on the buses.

I have been inspired by the Thomson Z8OA for a long time. Has MORE
load capacity and operating range of supply voltage
(+5V), than Z8OB from Zilog. Tested by practice (electronics)
:).  And there were also these Z8OV from Sharp. The best! We worked with him
the most“thick” skeins of MGTF-a (wildly upgraded computer). The percentage itself
~one minute after power was applied to it, it was warming up
so that the finger did not “hold” in the crystal area. :)              
                                                                
This is what I understand - “Powered by Z8O!” :)

That's right, I have a turbo without waita, i.e. RAM accelerates to 7 MHz    
and this, mind you, puts the percentage in even tighter limits in terms of         
time parameters, but it works for me without glitches.         
It really heats up like a stove, so I had to have a fan from the PC         
install, otherwise it would start to glitch as it warmed up... normally

AM> processors - which one is better, more reliable, etc.?????      
The coolest percentage I've ever used is Z8ХCOO1OPEC,    
by Zilog. It is designed for 1 OmHz, but that is what they put in       
General Sound, where it accelerates to 12 MHz, and no glitches :)    
At the same time, it does not heat up at all. Once they worked for me     
I was pleased with two such processors - one in GS, the second in a computer.       
like an elephant :) But one day my pulse signal glitched several times  
power supply (when turned on, instead of 5V, about 7.5V appeared),    
and both processors crashed. I tried to install Z84OOAPS in GS - where -   
it works for half a minute, but then it freezes and goes down      
no longer reacting to reset. In short, it’s lying around now      
GS has been collecting dust for half a year. I can’t do it anywhere in Dnepropetrovsk  
find 1O-megahertz percent. And I’m not looking anymore - I’m tired    
search.                                                         
    In short: in terms of reliability, both Z84OOAPS and Z8ЧCOO1OPEC are at their best,   
but the second one really doesn’t like excess hanpyru power supply.            
                                                                
           See you again! Bye, Anton!                          
                       Dale

I used all three of these processes. About BM3 I will say that it is enough        
buggy. Moreover, it worked on the computer, it was fine, but in     
AOHe froze as soon as nporobapubahe phrases were launched.        
3ato hardly got warm. And the most durable in terms of loads      
I would call GoldStar. If the buffer is brokenput, put          
GoldStar. It's a pity, but I haven't tested it for performance,     
I didn’t have a turbo yet.

Here we goI have such a trick, but not Gold Star                  
it’s not clear at all. SGS (although this can also be goldstar :)))   
I can’t check it now...y me SRI

       Previously it was TTL. And now everything is CMOS...

 Lastly, I can say that in our city in computers by name
'Quorum' usually there are standard Z8O from ZiLoG named:     
ZO8ХOOОЧPSC ...
