Hi,
I'm trying to track down a copy of the NEC V20 Hardware Manual. I've
managed to find a PDF version of the Software (programming) Manual, but the
Hardware Manual (which, typically, is filled with the info I need to get
this thing running) is a pain in the neck to find, especially now the V20 is
classified as obsolete by NEC.
I'm also after a copy of the schematics for the original IBM PC-AT and
PC-XT. Anyone got a set they can scan or photocopy for me?
Thanks.

There's a datasheet for the V20 (uPD70108) on partminer.com that
has dc/ac characteristics, timing diagrams, pinouts, etc. Sorry,
I can't help on the actual hardware manual. Can you get by with
docs for the 8088? I thought it was a drop-in replacement.
Where did you find the software manual?

I might be able to use

work properly in PCs when the 8088 was swapped with a V20.

Not that I know off.
The V20 did behave exactly like an 8088.
At some point I did use them on every PC and XT I could. The
additional speed was quite cheap. The only time I couldn't
use a V30 was in the Siemens PC-MX, a small 8086 Unix box.

Well, that's eactly the 186 behaviour. Now considering that the
timeing was also exactly like 186 (or real mode 286), and the
instruction set is the same, I still think NEC just used the
186 (188) core as template for the V20/V30 - Considering that
V40/50 where like the 186 with integrated perhipherals, you
may considere it as a two step knock off...

I have to step back here. I always thought the 186 had this already
fixed. Maybe I'm mixing up these two CPUs.
Didn't the 80C86/88 also have the double prefix bug fixed ?

It had all the 186 extensions, especialy Enter, Leave, Pusha Popa,

that on a V20 (but I did on the 186).
Furtermore the V20 did include a bunch of new, nice instructions
(if in 86 mode). Just I know of no software to use them. For example,
A bunch of operations for 4 Bit values - aka BCD and Bitoperations.

Excuse me ? AFAIR that's the way to check if you had a 286 or

is the decremented value, while 286 and above push the original
value, and the test (at least as I did it) was:
PUSH SP
POP AX
CMP AX,SP
Equal -> 286 or above,
Not Equal -> 186 or below.
To test for 186/88 vs 86/88 (and V20/30) was using the shift
operation. starting with th 186, the shift value was anded
by 1Fh. So you would load any value except Zero into AX and
load CL with 32, execute a shift. If the resulting AX was
Zero, it was an 86/88 (of V20/30), if not it was a 186 or
above.

I think that your memories of those details are a lot clearer than mine.
It's been a long time, and I never did much of anything with the 186/188,
so never really got the hang of where it fit into the sequence. I don't
have my files handy, and the few reference materials that are handy
(such as the MASM 5.1 instruction set reference) are unreliable and
very inconsistent. Between your knowledge and what it says, I'd be far
more inclined to trust you.

I've registered with Partminer, or rather their
other site
freetradezone.com. I tried to find a datasheet and it threw up a
"Distributor Access Only" error. A quick request for a CAPS Advisor 14-day
trial sorted that out. Needless to say, I now have full data on 95% of the
ICs in my junk box.

That would be great - thanks. Does the Techref
cover the uPD765 floppy disc
controller as well? (did IBM use that chip in the original PC?) Speaking of
disc controllers, I need a few uPD765s. Disc controllers and SuperI/O chips
are like hen's teeth around here. I've got a Holtek HT6552IR in unknown
condition with no data. Holtek did send me the datasheet, but my PC suffered
a hard drive failure (yes, current hard drives are still afflicted by the
age old problem of sticktion).
Someone also mentioned a copy of the IBM PC schematics was included with
Microcornucopia magazine? If this is/was true, I'd love a copy.
A memory map would also be useful. I do have source code for a PC/XT BIOS
(from programmersheaven.com iirc) so I don't need the BIOS sources scanning.
Now I wonder if IBM still have any Techrefs in stock...
And while I'm on the subject of PCs, I've tracked down a really nice Dell
keyboard. It seems like it uses a buckling-spring mechanism. This is based
on the fact that it makes a very loud click when a key goes down. It also
makes a "boing" type noise akin to a spring popping out and flying into a
wall. It's Dell P/N 093GDJ, FCC ID GYUM90SK.

I did the same, but to more efficiently run CP/M programs under an emulator
for MS-DOS. With better instruction-set compatibility with older
processors, the V20 had to do less emulation and could run more straight
code.
The target application? Scott Adams adventures for CP/M. :-)
I still have a V20 and a V30 left over from old C= stock from the local

I know it was highly compatible, if not completely. The DEC Rainbow could
take a V20 replacement for its 8088. The only other required change was to
the boot PROM, because the V20 completed a loop faster than the 8088 and
would cause trouble (not successfully boot) in the original PROM. The
putatative reason to make the switch was for an (approx., off the top of my
head) 5-10% speedup in execution.
I (think I) can supply details, including the change to the PROM, if anyone
is interested. I have not, however, tried the change myself.

The IBM Technical Reference Manual(s) included the schematics. But they
were broken up into a lot of pages. Dave Thompson ("Microcornucopia"
magazine) took the XT manual and a CAD program, and put the XT ones
together into a single large poster.

Hi,

Hi,
I'm trying to track down a copy of the NEC V20 Hardware Manual. I've
managed to find a PDF version of the Software (programming) Manual, but the
Hardware Manual (which, typically, is filled with the info I need to get
this thing running) is a pain in the neck to find, especially now the V20 is
classified as obsolete by NEC.
I'm also after a copy of the schematics for the original IBM PC-AT and
PC-XT. Anyone got a set they can scan or photocopy for me?
I can't help you with either of those, but I have a V20 if you need one.

What package and speed grade?
Better yet, can you tell me what the full part number of the chip and the
asking price is?
Thanks.
