Radio Shack's "TRS-80 Micro Computer Technical Reference Handbook" RS Part# 26-2103 was scanned and converted to a text based Word 97 document using OCR software. All the graphics, figures and tables were preserved and the document has been formatted identical to the original manual, with the following exceptions:

• Foldout diagrams were re-formatted to fit on 8.5" x 11" pages for easier viewing & printing.
• Some pages were re-formatted to improve readability.
• Schematic foldout pages (Page 107 & 109) were formatted to 33" x 9" page format. This makes viewing easier but may cause problems printing (seperate images available for printing).

The .PDF format file is available for download.

Model 1 Schematic diagrams (521k)

The schematic diagrams are 300dpi lineart images in .PCX format. The images are provided to allow you to cut the images into smaller pieces for printing on inkjet and laser printers. These images are already in the .PDF file so need not be downloaded, except for editing or printing.
