The graphics and a lot of design : ║ ideas were put forward by Rogue (grafix artist) and Void (musician). ∙ │ Because WE knew want we wanted out of a music development package, RAD · ║ has evolved into something we are very happy to use for developing our │ productions. We hope you dudez also discover how to be RADical...! │ | · : RAD woz Kiwi-coded in 100% assembler by SHAYDE . ∙ : · RAD's graphics were Oz-drawn in 100% ANSI by ROGUE and VOID. │ | Documentation by SHAYDE, Doc-Ansi by ROGUE. │ │ If you'd like to send us any of your quality tunes made with RAD, ║ please do so, and we'll include them in the next release pack! │ (Our contact address can be found within RAD) ║ ║ L8'er dudes! │ ║ ║ ║ · ∙ ─ ─- ── ─────┤ REALITY PRODUCTIONS - April 1995 ├─ ─ ── ───═─══─═══─══╝
