INMC80-5, page 20. In my review of the Econographics for the N1, where I say "is not acceptable", please substitute "is not unacceptable". The Econographics unit gives a very slight line between solid blocks of white, but it is not objectional. I am also informed by Nascom that the faulty piece of artwork for the track patterns has been withdrawn, and profuse apologies have

been expressed for any inconvenience. With any luck, any Econographics units around will now be from the correct track pattern. INMC80-5, page 58. For microprocessor, read macroprocessor. This is

obviously a computer error (GROANS and slow handclap!)


This is an OCR’d version of the scanned page and likely contains recognition errors.
