Re: Open source firmware for Gotek floppy emulator released

On the IFEL Master, does it have the IDE patched ADFS, or the standard ADFS?


I think we are both waiting for the answer to that... But I believe the IFEL ADFS routines are pre-IDE versions.

However, I can drop the old MOS 3.2 in to prove the point.
I'll try that and report back.

Re: ICE T Spartan 6 and adapter board.

Hi All

These ICE threads look interesting.
Is there an introduction or explanation of where the project is going?
I'm guessing ICE stands for in circuit emulation...
If thats the case, what are the benefits of emulation into the CPU socket compared to, say, the TUBE emulation?

Re: BBC Master screen interference PiTube direct

From what I've seen the issue is most pronounced on the x86 but is also present on the other processors that I've tried.
There is evidence of it in the 'new zx81' emulator by ROBC using the the native ARM proc, with the issue being inverted.
i.e. the artifacts are white on black.

Re: BBC Master screen interference PiTube direct

One thing you could try is editing cmdline.txt on the Pi's SD Card, and increase the value of tube_delay from 0 to 10, then 15, then 20 and see if this has any effect on the interference. Beyond 20 the Pi will probably not be recognised. It's possible this will make the interference worse, but that...

Hi Paul

The external one works fine on both Masters and my NulaBeeb.
