Nasprint 80 is a 2K progam which greatly extends and
simplifies the operation of Nas-Pen.New functions
supplied by Nasprint 80 include:
1 & 2
Output a title in each page
Text formatting with embedded control codes, e.g.
Change line length; change line spacing; change
margins; centre line between margins; new page; output
control codes to printer.
The program contains a parallel printer routine for a
Centronics type interface, specifically designed for the
Epron MX-80,but the program can be used with any
printer, parallel or serial, as the output is routed through
an address in RAM.
The program also facilitates the operation of a printer
with Zeap, Nas-Dis, De-bug, Nas-Sys & ROM Basic; the
software/firmware being used is selected from a menu
and Nasprint 80 then changes the necessary addresses to
produce hard copy output.
The program is supplied in 2x2708’s or in one
2716,together with instructions for fitting 2716’s in the
RAM A card. £14.95
