You've just about got the breaking points listed. The original ][ machines could add ][+ ROMs to get Applesoft, which was a requirement for several programs. Likewise, they could be expanded with memory up to 64k,which became a requirement later. An 80 column card (and whatever other...

I can't imagine what you're thinking of. ;-) Hard sectoring refers to holes in the disk surface detected by optics to signify tracks and sectors. The Apple Ii scheme makes no use of these holes, and so is called "soft sectored." It's all encoded on the disk surface itself (i.e. in software...

Exactly. Sectored-ness (hard or soft) is irrelevant in the Apple's case. Just avoid HD ('High Density") disks.

I think you probably did. :-) Here's Ken Fager's photo log of doing just that:

If you're going that direction, you have lots of company: http://dataswamp.net/apple2eserialterm/index.php http://www.bytecellar.com/archives/000113.php http://web.textfiles.com/computers/linux.gs.login http://pdw.weinstein.org/2007/06/apple-hacking-for-fun-and-profit.html

I think so, but I think it's probably going to be more work than you want to do for the 'lulz.' You'll want to start reading about Marinetti and Spectrum: https://sourceforge.net/projects/marinetti/ http://www.gwlink.net/sis/

You might want to take a look at a couple of projects that have come before. But first, you probably want to abandon all hope of re-using source code directly; whatever you are doing, it'll take refactoring to work on your target platform. ;-) Have a look at the LNG (LUnix Next Generation)...

"It depends." Take a read here: http://lukazi.blogspot.com/2009/04/game-controller-atari-joysticks.html There are different ways to adapt the digital-to-analog world of Atari-to-Apple controllers. And how games respond is going to differ as well. I think you're going to have to jump in and...

The 8-way directional joystick design of Atari is fundamentally different than the 2-dimensional potentiometer design of Apple. Do you have a particular type of game you want to play that this would make sense with? I.e. playing PacMan is probably easier with an Atari-style joystick than an...

If you want to avoid the work of programming the SCC (Serial Communications Controller) in your IIgs directly, you want to use the Pascal entry points in the firmware. The SCC is compatible with the SSC (Super Serial Card) at the firmware level only. They are completely different pieces of...

For others: ProTERM can be downloaded from here: http://lostclassics.apple2.info/downloads/?dl_cat=10 For arfink: Tony Diaz promised to post disk images of ProTERM: http://groups.google.com/group/comp.sys.apple2/browse_frm/thread/a675ca80390fab66# but has not yet. PM me and I'll send you...

You're not viewing zero page properly - it's like having 256 registers. ;-)

SCSI adapters come on eBay fairly frequently. Apple SCSI Rev C, RamFast SCSI, et. al. work fine. No. GS/OS is the closest thing the GS can run. And it's amazing just how close it is to early Mac OS.

Because you could buy a SCSI card from Apple, too. :-)

Nope, the whole system has assumptions about two drives per controller "slot." It just so happens that your slots are virtual (vslot 6 for 5.25", vslot 5 for 3.5"), but you still don't get to go above the limit per slot/controller.

The software for your card is here. You can format the "rest" of the disk with HFS once you've got GS/OS up and running (and updated to a non-buggy HFS driver) to recover the other 128M.

Right. Yes. You'll need to use your SCSI card's firmware or other software to partition and format the drive, though. ProDOS 16 will see at most 32 megabytes per partition, so it'll need to be divided up. But again, your SCSI card came with a way to do that. Which card do you have?

Right. You can safely remove it if you don't have any unnatural cards inside the case pumping out a lot of heat. A hard drive, for example, might fall into that category.

Yes, definitely. At one point, I got surrounded by good guys - all busily spouting advice at me (and fighting baddies for me too). Everybody's recognizable as who they are: creatures, weapons, etc. You bet - thanks for pointing it out! And as for your Apple ///... time to hit eBay. ;)
