  • 1. IIgs ROM00 to ROM01 Upgrade
    I just purchased a IIgs Woz Edition on eBay, I was assured that it had been upgraded to a ROM01 before I purchased it. Well of course it is a ROM00 and I don't have any more machines that I could cannibalise a ROM01 chip from. I don't need the video chip upgrade. Where can I find just a ROM01 chip to upgrade it? oz390gta
  • 2. Transfer files from IIgs to //e
    Is there a quick way to transfer files from a IIgs to //e - 3.5 drive on the iigs and 5.25 drives on //e... I do have a zip drive and a scsi card in the //e and a ramfast on the iigs... would it be feasible to have the zip drive on the iigs put all the //e files I need on there. Then transfer the zip drive to the //e and create 5.25 disks? Or would using a serial cable with Proterm be easier between the two machines? Thanks for help, Sam

Loading DOS 3.3 from a file like ProDOS

With 5 bytes of code (essentially LDA #$60, STA $BF30) stuck right below 
the run address of $2000, and resaving it as a BIN file, I made it so 
DOS.SYSTEM can be loaded and run from a DOS 3.3 disk.  This sounds 
useless in itself, and really, it is.

Now, there's a menu program, called Beautiful Boot, which installs 
itself into the boot track, providing a sort of mini-DOS, which can run 
any binary files if they are in the first 14 directory entries.

I'm musing about how one would make a bootloader that actually looks for 
a binary file named DOS 3.3, runs it if found, and if not, says NO 'DOS 
3.3' FOUND and exits to BASIC.

1.DOS 3.3 ASM load/save file?

Let's say I have a start-of-file and end-of-file address (but not a 
size-of-file), and want to save the file using type S, or I want to read 
the file at the start address and set the end address.  Something like a 
BASIC program. (In fact it is BASIC, just not FP or INT.)  I'm using CA65.

How would you do this?

BTW, this is a slightly tweaked EHBASIC.  I'd like to be able to have the 
LOAD and SAVE commands require filenames, if anyone's familiar with how 
EHBASIC works.


2.DOS 3.3 Cross-Compiler for Aztec C DOS 3.3 Shell Programs and whatever

Not exclusively. I succesfully merged the native mode DOS 3.3 Aztec C 1.05i 
Environment with the C65 MS-DOS cross-compiler that I originally purchased 
for the Commodore 64.

Part of my merge includes full support for the Aztec C DOS 3.3 shell 
programming environment which provides a decidely unix-like environment and 
TINY programs with commnad-line args and redirection etc.

I am not quite ready to release this bundle yet but anyone who wants what I 
got so far can request this in pm.

That's it... not much time lately because we're in our busy fishing season 
so not much time for playing on old computers.
