Nasprint 80

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

Centre title

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

operation of the chip, detailed advice on the interfacing to

various microprocessors, and comprehensive

explanations on the generation of music and sound

effects. £2.25 (no vat)

separate modes may be selected. Direct mode allows

values to be entered into the chip registers via the

a rapid appreciation of the chip’s potential. The second

mode turns the keyboard into a 7 octave ‘piano’,

displaying the notes being played as well as the values in

the registers. £5.95
