I’ve discovered a way to use a file on a computer as a FireWire Harddisk for another computer. This is a handy way to work with older Apple computers because it’s way easier than burning CD’s or using a read FW HDD.
The setup is not that complicated but still there is some to do.

It took some while but here is the new Vectrex game “P1X3L-pushr”, which is a remake of our own C64 game. The game was created for the Coding Compo at the DoReCo-Party 2013. Sorry that it took that long to make it public.
This is our first Vectrex release and my first steps on the 6809, which seems a great processor.
The archive includes not only the rom file but also the full source – have fun with it!

I’ve just published my 6502 code reorganizer which results in a better compression:
Last weekend I’ve finished my first CPLD experiment, which (of course) was an project for the C64. This small extension is a GeoRAM compatible RAM extension or a EasyFlash like extension. It’s possible to switch between them via software. In other words you can use it as pure ram or load cartridges in the ram and play (instead of burning eprom modules).

- The files loaded/saved don’t have an load address anymore!
- Simple file browser (cmd compatible)
- Keys reassigned (now matches the function)
- Layout optimized
- Help screen added
- Removed the “Modulgenerator”
- SMON or Multimonitor – your choice

With this small device you can reset your C64 by holding the Restore key down by 2 seconds.
All you need is an ATtiny and a little more, the price should be less than 2 EURO in total.

If you would like to have a language switch like I have, that can be done.
It’s now available on wordpress.org: Multilingual Text

Do you ever wanted to open a file while logged in a remote server via ssh on your local TextWrangler/BBEdit? Now that’s possible!
TextWrangler/BBEdit can open files per sftp (via ssh). This set of tools allows it you to launch
edit on a remote server, but your local TextWrangler/BBEdit opens the file.
Get it here: TextWrangler remote control
BBEdit: I haven’t tested it, but it should also work. (I do not own BBEdit)
I don’t like php’s getopt function, because it’s too crippled.
I’ve started a write a replacement function.
It has more options, is easier to handle and returns all non parameter arguments.
Fell free to use or improve it:

I was wondering whether I should use
NSInteger. It took me a bit but I figured it out!
On OS X and iOS the following table shows you the the size of the types:
char 8 bit
short 16 bit
int 32 bit
long system size
long long 64 bit
So, on 32bit OS X
long is 32 bit, on 64bit OS X it’s 64 bit (unsure for iOS).
NSInteger has always the size of an pointer.
Often asked: “Use int or NSInteger?”. Answer: use
NSInteger for pointers, ok usually you should use the pointer type itself, and for everything else use the size you require.
If you want exactly 8 bits, use
int8_t for sigend or
uint8_t for unsigned, for an integer which has at least those bits, use (
int_least8_t (analogue for 16/32/64 bits).
Performance: you can use (
int_fast8_t for the fastest type, which can hold (
int_8_t. But since (u)int_leastY_t and (u)int_fastY_t are defined as (u)intY_t on OS X and iOS it should make no difference. I use the direct types for when all the bits are used, and the fast types when I don’t use exactly but less bits.
At last: don’t forget the
ULL suffix for 64bit constants (you can use (
INT64_C(num) for always the correct suffix, also for 8/16/32), and the “%lld” in a formatted string for 64bit variables.
NSLog(@"number: %lld", 1LL << 48);)
If you have more information or maybe corrections, please post a comment.
