What about the MMU in the //e? Click to expand... How much memory does the MMU page in and out at a time? Both granularity, and within the memory map of the 6502?

Who would have guessed? I found this on Apple's site. It's ancient: Super Serial Card: Using with Machine Language

Also the 6502 has no virtual memory management, so fork() becomes meaningless. Click to expand... What about the MMU in the //e?

Urg, 6502 is one of the worst processors for C let alone UNIX. The size of the stack (256 bytes) is crippling. So you have to do the stack yourself. Also the 6502 has no virtual me…

Ok, now I'm just really pushing things here, aren't I? Aside from my project to write a network game for the Apple II, I also want to look into Unix or any other multi-tasking i…

Thanks for the JSR. I was looking through more manuals, trying to figure out exactly what a PR#2 did. The page with the Pascal 1.1 entry points was right across from the page with …

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 …

If its any indication, I got 7 years from the 8x TEAC drive that came with my 1400 (which I've had since new). And my iMac's original Panasonic CD-ROM drive (which is a notebook un…

Hi, I'm using the built-in SSC emulation in my GS and have it connected by serial port to a Classic running ClarisWork's communications module. Everything is perfectly fine: I can…

^^^ ECC is not your friend in a Mac; I've had no luck with it in any model. Which is too bad, since I have a stack of the stuff.

Slot load drives, no matter what brand, will still break under heavy usage, especially if often used for writing discs. You don't have much choice with your PowerBook, but normally…

Double-sided RAM cards should pose no problem, as that implies low-density chips as the CRT iMacs need, The specification, which you may not have if you were not aware that you ne…

Never had an issue with double sided. I even had two 512MB sticks in my 350MHz once.

I got some 2x256mb pc100 sdram chips recently, and they dont work with the iMac. They appear to be double-sided (chips on both sides). Is there an issue with double-sided sdram me…

What are some good Pioneer replacement drives that would be "compatible"? Would all slot-loaders that would fit work? How can I find out more? xlr8yourmac.com is out-dated but is t…

Just an FYI, it's a huge pain in the ass to do sort of drive replacement on a 12" PB.
