Re: change a bit in a variable ?

Oops, you are right.

It should have been: <input> AND 10111111 <--- clears the 6th bit

Too hot! :)

Re: change a bit in a variable ?

In case that Hisoft Basic doesn't support logical operations (AND, XOR), that could be pretty tricky. :) If it does, then it's easy:

<input> XOR 01000000 <--- flips the 6th bit
<input> AND 01000000 <--- clears the 6th bit
<input> OR 01000000 <--- sets the 6th bit

Re: What is the definition of commercial use?

I guess you're using the "Download as ZIP" option - if you clone the repository with 'git', then 'git log' will show you the author's name and email address.

He seems to be pretty active on AtariAge, following his habit from AF, i.e. spawning offtopic threads with repetitive content.

Re: DEVPAC 68881 required error

EDIT: Also I wonder if the combination of 68040/68881 is even allowed in Devpac, considering that the 68040 has a builtin FPU. I guess it's harmless - there isn't a 68881/2 instruction which isn't allowed on the 040 (natively or via emulation). IIRC there is only one or two opcodes which have the s...

I used to want a cosmosex, but now that the netusbee has proper usb drivers and supports keyboard and mouse I don't see the need for it anymore... Unless there's something I forgot.
Games, maybe? You can use NetUSBee's mouse/keyboard only for system applications.

Btw Ube - great idea, love it!

Re: STE DAC FPGA issues

Personally, I don't find the possibility of breaking the system so terrible if it would be possible to always reuse the original ICs (to gain 100% compatibility). If you decide to use FPGA alternatives then yes, one gain is the ability to run the ST(E) on higher speeds but the far more important gai...

So I don't really get the confusion ?
Oh, now I get it. I totally overlooked the fact that the reference ST doesn't have a Blitter! Thank you for the detailed explanation.

Re: True 16MHz Mode

I wanted to ask earlier but seeing the Falcon numbers made me nearly sure... don't you find that 1000% blitting increase suspicious? Now, compared to the Falcon, it's just a little over 100% (what I find believable) but what I certainly don't find believable is that Falcon has a 1000% faster Blitter...

Re: TT030 replacement case fan and where to connect

DONT just plug it straight in. You will be able to plug just the +5V and GND pins of the socket into the connector to power the fan. Here is a picture of the pinout of the Noctua 3 pin so you only plug the red and black part of the socket in and not the yellow. Why 5V? Isn't the fan linked in the p...
