TRS-80 Model III and Holmes VID-80 Schematics / Technical Reference

[Neil Breeden]

Hi,

  I'm looking for a Technical Reference manual / schematics for a TRS-80
Model III and the Holmes VID-80 add-on board. 

  I've found a fair amount on the model I and 4 via Google however there
seems to be nothing on the Model III.
