most economic & convienient & easiest way of testing

[hugo929]

Hi folks

I am longing for a board or fascility to test my 8080 processors.
The bigest wishes is to test my 5G8080 series.
What is the most economic & convienient & easiest way for the testing?

I saw some 8080 board on ebay, but expensive and status unknown.
thanks

not on my short list of things to do.. but I have been trying to track down plans for a 8080 SBC to build

The board really isnt the issue.. more the software coding for testing the 8080s while on the board

Two questions.. probably only one you can answer
1) do you know if the pinout of the Chinese clone the same as i8080
2) is the pin spacing same as Western chips or is like Russian chips?

thought of a 3rd question.. do you have any info confirm it is clone of i8080 and not actually clone of Am9080?

Best way to check 8080's would be an
early home computer I think. Preferable
with socketed CPU of course but most are
socketed I suspect. If you get a coursor
on the screen and if you can type in some
text it is very likely the CPU is ok.
If the computer has a BASIC- or else
interpreter you can write a small program,
e.g. a loop and it is just great "to see"
the antique processor working!
Only problem is that most of those early
home computers are pretty rare and expensive -
but furtunately way less exensive than an
Imsai Altair! Indata's DAI was one of the few home
computers with a 8080-CPU!

thanks stu for so many questions. I am still not ready to find an answer.
thanks doccy for the guide.
I will get back to this thread when I get some update.
Currently I have no time on this. lots of work to be done

I have a single board computer with 8080 on it. It's school property but they don't care about it as they did 30 years ago. If I could locate some documentation about it, I could test my NS 8080 on it.

hugo, have you looked around your area for, say colleges and or high schools lately? I know the Chinese are quick at dumping old computers once they think they are old but in case some of these college training computers still survive, you may be able to get one.

BTW, when I was in junior high, the university dumped all its apple clones (HKC 8800, weird, I can't find any info on it, any luck on Chinese forum maybe?) to the high school when going with PC's. When I graduated from college, the university probably dumped most of the 486 and pentium in favor of PII and the new PIII. I bet if I go back now, they don't have anything older than P4. Older computers get sent to villages

not sure if you saw my post Hugo.. but there are still "cheaper" options that still come up for 8080 test boards

http://www.ebay.com/itm/320830430944?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649#ht_500wt_1066

will still cost me me in the end around $230 by the time I ship it here
but thats about 10% of going rate for most setups

Good thing.. even if there is a issue.. it comes with original schematics to sort any issues due to age

[Neon_WA]

the next cheapest option for testing 8080As

http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&_trksid=p4340.l2557&item=130661260270&nma=true&rt=nc&si=MtYony2gO7i%252F0xLjYjhFmtpFwBg%253D&sspagename=STRK%3AMEWAX%3AIT&orig_cvip=true&rt=nc#ht_500wt_1076

and about one of the only ones that use a screen
