Agreed. It shouldn't be the only place it is kept, but archive.org is necessary since so many personal sites have disappeared suddenly over the years.
The two versions of the Technical Notes I knew about before were clearly from the same scan as they cut off the same text. They differed greatly visually, but neither was better quality. The web8201 version was very low resolution while the 1000bit version had 1-bit color. I suspected they both were reduced size versions of some scan I couldn't find online. That's why it occurred to me to try averaging them together to get something more reasonable. Since Stephen's file is so much larger, I wonder if it could be the lost version? --b9 On October 10, 2026 5:40:05 AM PDT, [email protected] wrote: >Hi, > > > >Put it up on Archive.org so everybody in the world can find it and have access >to it. > > > >Every manual for everything vintage needs to be added to Archive.org. > > > > > > > > > >============================================================================================== >C U L8r, °|° Walt Perko °|° "Kids ... teach them the good stuff, and >they still learn the bad stuff on their own." > >http://www.R2Pv1.com/ RoboGuts™ Intelligent content for 3D printing making >S.T.E.A.M. education better, easier and more affordable > > > >Experiments to learn how to use various Electronic Components, Structured >Computer Programming, Phonemes for Speech &Song in any language, and Art. > > > "The World Needs a New Economic Model" >============================================================================================== > > > > Sent from the Cyber7 > > > > > >From: M100 <[email protected]> On Behalf Of Stephen Adolph >Sent: Saturday, October 10, 2026 4:13 AM >To: [email protected] >Subject: Re: [M100] NEC PC-8201A technical reference > > > >I have a copy of PC8200_TechNotes.pdf. > > > >where can I send it? 69MB > > > >On Sat, Oct 10, 2026 at 12:33 AM B 9 <[email protected] ><mailto:[email protected]> > wrote: > >The Technical Manual - First Edition exists online ><https://www.web8201.net/Files/LIBRARY_web8201/NEC8201A-TechRef.pdf> and I >believe it is what John needs. but the scan is spotty in places and the low >resolution is particularly noticeable on diagrams, such as page 238. > > > > The Service Manual also exists > <https://web8201.net/default.asp?content=/Files/LIBRARY_web8201/NEC8201A-SvcManual.pdf> > .
