wtb: books,manuals etc on older microprocessor 6502,z80 etc

[mc]

hi after any books manuals etc any printed material on older type
microprocessors eg 6502, sc/mp,z80,8080,8085,6800,68000,etc. If you have
any of the books on processors or their interfacing ..and happy to part
with them .. let me know of what you have and how much .. also after any
older style early development boards utilizing early microprocessors ..

Ladies and gentlemen,
bought the Jaycar modules (QC3590) etc, downloaded the .pdf, but it
fails to give the actual antenna connections! Any clues before I start
to rip the sheilded package apart?

Hi,
from the pics in the pdf file it looks like there is a small PCB protusion
form the case. This would appear to be your antenna conections. the centre
track for the centre of your coax and the outer for the screen.

Hope that helps
Greg

oh, yeh forgot to ask, why is this here under the op?

Why fork out good money for them?
Motorola has all their manuals on their site in PDF format so go there and
get them for free.
Then go to Zilog's site and send them an email asking for a Z80 manual for a
"prototype" and they will post you their Z80 manual for free.
Note that the 8080 is the predecessor to the Z80. It was made by the same
guys when they worked for Intel. the Z80 is a majorly enhanced version but
still compatible.

Hello Greg,
Not quite sure what you mean by the op?
Am using Agent, posted only to aus.electronics and posted as a new
thread (according to my headers)
Am curious
Grant R
PS the info about the connection of course makes sense- many thanks

Hi Grant,
well perhaps it's my ISP again. Your message is threaded as a reply to mc's
post on old micro books.
Good luck with the 2.4 Ghz stuff. There is another mob that sells that type
of equipment that may be worth looking at, try http://www.allthings.com.au
located in WA. I've bought cameras and transmitters etc from them in the
past.

Cheers
Greg

Hello Greg,
Yes I've used stuff from allthings before- just thought I'd give these
ones a go. You know, sort of striving for perfection and attempting to
do it for nothing!
Cheers
Grant

Wasn't the V20 just NEC's version of the 286?

: hay, don't forget the V20 chip that ran both z80 code and 8088 code. i
: think it also ran code for soemthing else too, but i cant rmemeber
anymore.

'Just'?? Man, that thing was *fast*! I think it came out as an 8MHz beast!

It was (still is!) compatible with the 8088, drop-in replacement. A
popular device to speed up your machine back in the old PC days. Lower
power too, so was popular in laptops.
And yeah, I think it was also Z80 compatible somehow...
NEC had a whole range of the V series chips. The V30 was the 8086
compatible version from memory.

and what about those super fast 80bit IIT math co-processors!

Geeze that brings back memories...

Yes Enjoy Dialup I also still have sentimental feelings about
Microbees too. In fact I have about 30 Microbees and related
manuals, documentation etc, about 25 green and/or orange
monitors and 1/2 dozens dot matrix and daisy wheels printers in
my shed that I just don't have the heart to throw out or give
away...yet. Doubtless the day after I throw them out they will
become valuable collectables.

Oh and I have also got dozens of 300 and 1200 baud modems.
Can't see them ever becoming collectables though.

 

[mc]

if you have 30 of them you be able to sell few then ..

No I had a V20 chip in an XT motherboard I think it ran at 2.8Mhz... no
it was not a 286

Hazey memories here...

I vaguely recall the V20 & V30 chips from NEC were far more capable than the
8086 & 8088 chips they emulated. I thought they both ran a 16 bit
architecture, but the restriction was more in the peripherals available that
could run with them? At the same time, I thought the 8086 was a 16-bit
internal architecture, running 8-bit access to the outside world, and the
8088 was simply 8-bit inside & out.

I remember seeing a Microbyte PC running on a V30 chip, and being blown away
by how advanced they were for the time. Intelligent fan speed, upgradeable
bios via floppy disk, built-in scsi, built-in game port, video port, etc,
etc, etc.

Our microwave is probably more intelligent now....sigh.

Here's a good reference:
http://grafi.ii.pw.edu.pl/gbm/x86/16bit.html

Takes me back a while - I recall writing a video driver routine which needed
to recognise CPU and video chip, amongst other things. Man I am so glad I
don't do that any more!

Cheers.

thats it. it ran 8086 code too.... three cpu's in one!

I didn't think there was any difference in code between the 8088 and
8086? Both were functionally identical except that the 8086 accessed
through a 16bit bus. The 8088 came out after the 8086 to allow the use
of cheaper 8 bit interface components.

Then there was that briliently designed GUI with a true multitasking kernal
OS/2 which M$ refused to develop. It took M$ 5 years to catch up with the
elegance and stability of OS/2.

OS2 - Probably the best operating system we never had.
