i belive it was some kinda of copier, justhat Dave Helm made his own verion.
He burned it onto eprom and stuck into a Plus 4 cartridge,which i sent him, he took out the chip that was already inside the case and place it with the one he made.. here what i found on the Maverick.
Maverick was a follow-up to Renegade, and included a versatile Parameter Copier for dealing with copy protection.
But it was much more than that - disk editor, file viewer, GCR editor, disk menu creator, RAM/REU tester... Look for V5 which has the most "stuff".
So it may be the same as this, it may not be, one other peson had one sent to him, which was Peter Hanson a Keen Plus 4 user known as the Plus+4 king.
Peter i knew well we was alway on the phone to each otherwe even meett a couple of times, he was a good friend but an idiot sometime.lol we also met Robert Bernardo, a CBM collector from ThE USA, he runs a CBM club monthly in the states..
http://videocam.net.au/fcug/ this is his site,, coz i lost contact with rob a few years ago i tried calling him this morning around 2:30am, as it was around 8:15pm in the states, but i had no answer, i would of asked him for peters number so i could ask phim more info on the maverick cartridge.
So just to let you know Maverick was never realy release on the Plus 4, only a couple Beta Test Carts was made by Dave helm, and me myself and peter hanson was the only ones to get them that i know... So these are going to be the rarest Carts for the C+4,and gota be worth somethink.
coz thewre was no way putting the cartridge name on the cartridge i just wrote it on some paper and stuck it on.lol here an image of it.
so any intrest herefor the C+4 maverick Cart make me an offer befor i put on Ebay. it must be worth somethink like i said as thiswas never release to the international public that i know of it Dave Helm own project that he only gave to 2-3 people. To be honest i never realy used it i just got it to add to my collection of commodore stuff.lol i sold the C+4 ages ago i just kepted the more inportant stuff, and stuff that maybe collectorable in the future.
Oh i asked Rob Bernardo in an email if he could find out how much a new OS/chip would be for my CMD 40-meg Hard Drive i wait his return email will let ya know if i hear anythink, so i wont advertis the CMD Drive just yet.
