Hi, I was wondering if the Mac II can run without the FPU. Thanks!

I think you should talk to Snial. Think C has a couple of small demos that involve a GUI, and then you can cobble together some other code to get the job done.

Thank you

I see code in this order: SetFPos FSWrite SetEOF GetVRefNum FlushVol, should I follow this order every time I write data? Thanks for your answer.

Is this microcontroller an extension of the 6502? I wrote my own emulator because the MAME code is just too complex and I wish I could get to know this machine by writing a emulator. Thank you, I hope this stupid question didn't bother you.

Thanks, I spent a lot of time searching for MAME but came up empty handed, Google doesn't seem to have any info on MAME supporting PB.

Am I to understand that using SetFPos to point to the end of the file and then using FSWrite to write new data?

Thank you, I took a look at your screenshots and I probably know what I should do, do you mean you can't find volumes 1 to 3? I was wondering if it is possible to continually add data to a newly created file just through SetFPos.

Sorry to confuse you, I'm aware of the standard C libraries, but I don't really want to use them in a Mac, instead I want to use the toolbox routines.

Hi, I have searched for information and the behaviour of appending data to a file seems to involve a function called SetEOF, do you have any other information to provide, thanks.

Hi all, I was wondering why there aren't any emulators that can emulate PB and I was hoping to touch on this. All I know is that it uses the 68000 PMU ASC and I would like to know how much it differs from the Mac Classic and if I can continue this work based on the MacSE emulation. Thanks guys.

Hi, I know I'm asking a bit too much, how should I do an append operation on a file, like wb+ in open? Thank you.

Thank you, it works, what I meant was that malloc works fine without the need for an L after the number. on a side note, it's been a long time since I've seen code that needed an L after a number, I'm spoilt by modern compilers. LOL

Oh thank you so much, I'll try that, malloc works fine, this one confused me.

Hi, I checked the SIZE, it's 1024, here is my code, I put NewPtr at the top of main, it doesn't complain about any errors, but once I use this space it triggers a system 25 error, which I know means out of memory : MaxApplZone(); buff = (unsigned char*)NewPtr(128 * 1024); if(buff == NULL)...

Sorry, I'd like to program on a classic Mac, the kind with only 4MB.

Oh, you mean NewPtr should be called before InitGraf?

There is no code other than some window initialisation, no recursion or anything else. By the way, is there a compiler that supports the C99 standard on a classic Mac? Declaring variables at the beginning is very cumbersome.

Maybe I should change my compiler. lol

Hi, I have set the partition to 1024 but NewPtr and NewHandle both fail with the error message Insufficient Memory. My environment is SE with 4MB of RAM. in the end I was just hoping to get a 32KB space and it still fails. Oh, and I've used MaxApplZone at the beginning of the programme.
