CAD (1985)(Voltmace)

Post by sixxie »

Program dated 1984, tape dated 1985

Requires the Voltmace interface, I think, hence the FC ERRORs

This is interesting!

It seems we don’t have any information on the Voltmace interface in our wiki. Can someone shed some light about it?

Delta14b (14 button) Handset/Joystick

http://www.colorcomputerarchive.com/coc ... 201985.pdf

delta 14b handset.
The complete Dragon joystick system Voltmace,
the UK's largest computer joystick manufacturer has done it again ...
The delta 14b handset and interface for the Dragon 32 or 64 microcomputers.
Voltmace's well known delta shaped joysticks can now be found with more buttons,
11 more buttons, individually programmable for more action, control, more glory.
These additions have not however let us lose sight of why we are the UK's largest manu­
facturer, our design. Super sensitive fingertip control .with fast, centre sprung
return action, means you always know where you are.
Tough, solid steel shaft, encased in a smooth nylon sleeve, handles even the roughest treatment
and ensures hours of easy, fatigue free use. New analogue potentiometers give
corner to corner control, and total compatibility with all software currently available on the market.
Switch joysticks as the word suggests can either be 'on' or 'off and therefore cannot be used with programs
that require analogue control, like flight simulators and computer aided design programs (C.A.D. 32).
Connection of the delta l4b handset to your Dragon micro­computer is made via the delta l4d interface.
This plugs into the cartridge port of the Dragon with an external lead running to one of the joystick ports.
No soldering or special technical knowledge is needed to install either the handset or interface as everything simply
plugs in.
Utilise the full potential of your delta 14b, (14 button handset),
with our superb C.A.D.. 32 program,
using HiRes graphics draw: lines; circles; ellipses; boxes;
fill in areas in four shades; scroll up and down (using joy­stick);
get and put, to move or repeat shapes; plus two sizes of text graphics.
Unlike ordinary computer aided design programs C.A.D. 32 is really easy to use.
The program is supplied on cassette with a printed overlay card for the 14b handset.
Because the design functions are labelled and controlled from the handset,
there is no requirement for an on-screen menu which allows full use of the screen area for design work,
you can now sit back and relax while your Dragon. does the hard work.
The screen dumps shown here were all produced with C.A.D. 32 using the delta 14b handset and interface.
(Project X was designed and produced within 90 minutes).
Finished or part finished designs can be saved to tape or disk and reloaded for printing or amendment.
.
There is insufficient space here to describe fully everything C.A.D. 32 can do, so why not come along to the next
6809 show and see it for yourself.

That’s great, thank you!

It would be nice to know how the interface works.

I suspect that it’s just sending the joystick signals through the external lead and maybe making the buttons appear as keypresses, which would make cad32 work with a regular joystick and the keyboard.

Of course they could just use another i/o port for the keypresses so that you need the interface...

Pretty sure it must map some new IO, as the BASIC programs PEEK an address for their input...

I don't have one though - and I don't really remember how I got this tape!
