After rummaging around in the basement the past few days I discovered that I had a rather large stash of specific pieces of Atari gear. Now I cant compete with Kline's 50 some 1200XLs, but I do have at least 24 1050s, maybe six boxed. 3 completely boxed XEGMs. Maybe 8 800s.
So what is the largest amount of Atari gear you have stashed?
Why couldn't one create 26 double density sectors? Not enough physical media space per track?
Poking around the Internet I couldn't find a well articulated discussion on exactly what is different on the physical media, let alone magnetic data portion, of a SD sector vs a DD sector. The reason I'm going down this strange path of thinking was how could Atari squeeze 26 sectors for their Enhanced/Dual Density format with SD sectors.
I also saw that SD is done with FM, and DD with MFM. I'm assuming that ED was done with MFM but then ED disks are readable in an 810 drive which, I thought was only FM.
I also read that there is absolutely no difference between a SD and a DD disk when it comes to magnetic formulation. I find this a bit questionable given my experience with SD disks and that there is a major difference between DD and HD.
I'm not an Intellivision gamer by any means but i do happen to have two nice units and recently considered selling them along with maybe two dozen or more boxed games. I noticed one was a 2609 and the other a 2609A. I have yet to find any technical details on the difference between these two units other than an off handed mention they use different screws. I didn't see anything in the FAQ either. So what is the difference?
I also noticed that the controllers fit snugly into the 2609 but not the 2609A plastic. On the 2609 they almost become part of the case, where on the A they extend out the side just a hair. Also, of the four controller (two on each unit) one of them does not have a lip at the top of the controller but is rounded smooth.
And I also noticed that on the 2609 unit the controller cables are excreting an oil but the 2609A's are not. These units have been packed away and stored in climate controlled rooms for decades, so I don't think its an environmental issue.
