Matt Boytim was kind enough to provide a scan of the Multi-Pen Plotter Service Manual (Catalog 26-1191) Cover. Thank you Matt!
Pascal Holdry has completed development of the 26-1126 High Resolution Graphics Kit for the TRS-80 Model 4 and 4P. The mechanics and electronics are compatible with the kit 26-1126 and it is compatible with the programs developed for the 26-1126. More information can be found here.
Ian Mavric is now making an improved version of the Grafyx Solution 5.1 board which fits inside the 4P, so now all of the Model 4 computers are covered.
Check out the installation video for the 4P

Pascal has advised that work on the Model III/4 NEWCLOCK/80 is complete. You can download schematics and Gerbers from http://www.prof-80.fr/newclock-m3-m4/prototype-newclock-80-m3-4.
He asks that if anyone has a a Model I NEWCLOCK/80 to please contact him at pascal dot holdry at wanadoo dot fr.
Pete Cetinski has let me know that his Wikipedia client for the TRS-80 Model I, called TRSWiki, has been released. Since this would require both high-res and an internet connection, this would be for those people who have purchased the MISE (Model I System Expander). For those interested in learning more, please visit http://pski.net/trswiki/.
Pascal Holdry continues to reverse engineer popular TRS-80 hardware add-ons. If anyone has a NEWCLOCK-80 for the Model I, and can send High-Res pictures of the solder side, it would greatly assist his efforts.
