Amiga Hardware Issues and discussion / Re: How can I get Furia Tune onto my disk?
« Last post by AndyFC on September 22, 2023, 11:09:01 PM »
I've looked up FuriaTune and it seems to be a small file which will easily fit on a floppy disk.

If you can boot to Workbench you should be able to run a tool like Crossdos which will allow you to read a 720 DD floppy disk. If you can get this working, and you have a way of writing to a floppy disk on a pc then you could use this method to copy the file.

Another alternative is to put your CF card into a PC and use Amiga Forever to mount it in the emulator. You could then copy FuriaTune to the CF card.

To start with do you have a PC with either a CF card reader or a floppy drive?

Amiga Hardware Issues and discussion / How can I get Furia Tune onto my disk?
« Last post by JacobStevens on September 22, 2023, 01:06:18 PM »
I'm relatively new to Amigas and could use some guidance. My setup includes an Amiga 600 with the A604N expansion, Indivision ECS, a compact flash IDE adapter, and a Gotek floppy emulator. Everything was running smoothly until I installed the new Furia accelerator. Since then, I've been unable to boot from the compact flash, and I've heard that this could be due to the need for a faster flash card. I can still boot from floppy ADF images, although not all of them seem to work, though I'm not sure if this issue is related to the recent changes. Interestingly, if I boot from a Workbench ADF, I can access the hard drive. Now, I'm keen to use Furia Tune to optimize my setup. My question is: how can I get Furia Tune onto my disk? I apologize if this sounds like a basic question. I have Amiga Forever, and I'm wondering if it's possible to create an ADF with Furia Tune on it using Amiga Forever.

Greetings, everyone! I own a tank mouse labeled as "TDK-T12V," and I'm in need of replacement switches for it. I purchased switches from AmigaKit, but unfortunately, they don't fit (they are too small). Could you please advise me on where I might be able to locate the appropriate switches? Thank you!

Amiga Software Issues and Discussion / Re: OS 3.2 - Is it the cause of all my problems?

I have removed these new versions from all my systems. I still use OS3.9.

I know it's problems and it doesn't do dirty tricks to me.

Amiga Hardware Issues and discussion / Re: A2000 serial speed
« Last post by Castellen on September 20, 2023, 09:14:23 PM »
While the A2000 serial port will operate at 115200 baud, the limitation is that the 68000 CPU is not able to service receive data interrupts fast enough, meaning you'll get a lot of RX data over-runs, even if you use hardware flow control.  i.e. a loss of serial data.

If you have a CPU expansion, such as a 68040, you shouldn't have many issues with transferring large blocks of data at 115200 baud with the onboard serial port.

You can do more with third party serial port expansions since most of them include a FIFO buffer in hardware.  This results in far less interrupts needed by the CPU to fetch the received data, since the interrupts collect received blocks of data from the FIFO buffer as opposed to individual bytes.

I was under the impression the A2000 needed for the -5V for the boot process.

The A2000, as with other Amigas, only needs +5V to boot normally.  If you want audio output and RS232 serial, then you need both +12V and -12V as well.  Most floppy drives and mechanical hard drives need both +5V and +12V.

The A2000 also needs the 50Hz/60Hz tick signal that normally comes from the power supply.  It won't boot without it as this timing reference increments some of the hardware timers.  For non-original power supplies that don't provide the 'tick' signal, you can change main board jumper J300 from external to internal which drives the timer from an internally derived signal instead.

Huh, I was under the impression the A2000 needed for the -5V for the boot process. Thanks for the info.

Amiga Hardware Issues and discussion / A2000 serial speed
« Last post by RetroNinja on September 20, 2023, 05:43:28 PM »
Hello,

I'd like to use my A2000 to connect to a PCengines router. The router talks through the serial port at a fixed speed of 115200. I've read other places that this speed is too fast for the A2000. Does anyone know if the limitation is from CPU+custom chip? just CPU? Can I install an old Zorro II GVP I/O card (parallel + serial) to get a higher speed? With the serial processing handed off to the I/O card would I be able to achieve the needed speed?
