:mad: - customs just charged me import tax and a clearance fee to get my Blitter. More than half of the the original cost.

The clearance fee alone is £12
Damn :( I'm not getting anywhere fast in the hunt for blitters either :(

Re: Hissing and whistling in the STe audio output

It looks like the problems start right after the first op-amp ? In that case, it would have to be getting some frequency from somewhere, looks like it starts off at about 1.3KHz, also at 15.6KHz. I would have to assume the noise is being introduced by the power rails to the op-amp. That wouldn't be ...

Re: STE V1.5 32MHz BOOSTER - STATUS

I have been trying for the past few hours slow down the CPU on bus access (more time in 8 MHz mode like the previous V1 booster).. While this works, it actually works out slower running at 36MHz than the V1 running 32MHz. This is because the asynchronous clock needs to be synchronised which adds del...

Re: My new toy...

Those took a while!

Also found if I have all the cooling fans running, its very easy to get the ABS off the bed once its finished printing.

Re: STE V1.5 32MHz BOOSTER - STATUS

https://www.exxoshost.co.uk/atari/last/storenew/#0147 2 in stock currently.. will be more later (when the 3D printing has finished) . I'm classing them as a BETA board due to recent chaos Worst case is I will have to start knocking them out with a 32MHz OSC.. but will see how the 36MHz ones hold out...

Re: STE V1.5 32MHz BOOSTER - STATUS

:thumbup: Yes, plug in stuff isn't great, but as people were breaking their STE trying to remove the old socket.. its the lesser of the 2 evils..

Yeah, pin alignment took 3 or 4 or 5 PCB attempts to get it right :( Probably mentioned it "somewhere" in the tread..

Re: STE V1.5 PLUG IN 36MHz BOOSTER (production board)

TROUBLE SHOOTING. First of all. GB6 should be run for several hours minimum to prove stability. As mentioned previously in my main development threads, hardware tolerances are huge contributing factors for things going wrong. Unfortunately I cannot develop the booster which may work "out-of-the-box...
