Amiga Ranger chipset
« on: March 25, 2018, 12:14:30 AM »
Was looking at the AA+ Wikipedia article linked in another thread, and clicked the associated link for the Amiga Ranger chipset article here:

https://en.wikipedia.org/wiki/Amiga_Ranger_Chipset

It says this:
Quote
Jay Miner made sure that the Ranger chipset was completed and fully tested before he left Commodore in hope that one day the company would release it. But at that time, VRAM was considered expensive compared to DRAM, so Commodore refused to release Ranger for its high price which was unsuitable for the low-end systems like Amiga 500 to cover its costs. Dale Luck is in possession of a Ranger system prototype, but it's unknown in what state it is.


I call BS.  Jay Miner told me that a 128 color chipset did not exist many years ago in a BBS chat.

Does anyone know where the info that a Ranger chipset was complete came from?  

I know a supposed Ranger prototype was in the possession of Dale Luck, but that was a system design prototype and not a chipset.

Considering the number of eyes at Dale's garage for Amiga 30 I would have thought something about this would have turned up. Never know, though.

I believe the prototype Ranger was found and shown at Amiga 30, but it was a very early prototype for a new overall system not a new chipset.

What that states is that the chipset was designed and tested, it doesn't say it was produced.
When Lorraine was first shown, it wasn't an integrated chipset yet, just a design implemented via discrete logic.
Design and testing of a chipset occurs BEFORE its implemented in silicon, as changes become much more difficult once its in dedicated silicon.


It says it was "completed and fully tested".  

Miner told me "Nope, never was such a thing".

Um, Wikipedia is not 100% accurate, you know. :lol:


Of course, thus why I started this topic.  I was hoping some people might have more insight into the legend that was the "Amiga Ranger" and why some think the chipset existed.

Well, like most legends, it gets better and better with every re-telling. In fact, I think at this point it is expected. I've heard and read so many things over the years that I'm not sure what is factual and what is not.

From my understanding it was based around an 020/881, Carl wanted an MMU (851) for protected memory for a more modern Exec (he talks about this as one of the reasons he left), VRAM used for chip memory, and it supported a few high resolutions (1024 x 768?) and I thought a VGA mode without interlace. Again, it gets better with each retelling.

I too used to chat with Jay on his BBS (The Mission IIRC / he was Padre). He was awesome to chat with and extremely nice. Also met him at AmiExpo in Chicago and he was just as friendly and outgoing in person.  A real class act.

-P


Thanks!  I think I only chatted with him that one time, long distance charges probably kept me from calling back more often - I don't remember.

I'm glad I had the foresight to print out the chat log and keep it.  I came off as such a fan boy, but it was fun to go back and read.  I tossed so many things from that point in my life that I wish I had kept.
