"If you collect extreemly rare keyboards and synthisizers this is it !
This is a mint.. like new, ( 1985 ) never used Armonyx 8000 system ! The keyboard alone weighs over 32 lbs. The keyboard is made with extreem quality. It uses a light pen to draw your waveform and the light pen must use an RGB graphics card with light pen port on it. Yes that's right, we're talking XT DOS systems.
What a beautiful collectors item... for personal collectors or musems.
I'm sure it all functions fine, but am selling "as is "... no returns.. the box is too big to shuffle around much. I'll double box it which will take some time.
The software should be good... but setting that many years in a box, I don't know if the sofware is still good on not. ( should be. )
Installation Requirments:
IBM-PC hardware and software compatibility.
At least 256K system RAM
IBM-PC color graphics adaptor or compatible.
1 5 1/4" floppy drive
10" X 4 1/4" minimum board space.
Dos 2.0 or higher
It notes that if you own a Tandy 1000 computer.. that it has a light pen port on the back of the computer. Other wise, you'll have to make sure your RGB card supports light pen port.
