Re: TF536 - Freeze on Disk Access?

Cheers. I'll dig out and set up my revision 5 A500 motherboard tomorrow and see if the behaviour is the same. I am using Micron memory chips on the 536 and don't have any of the Samsungs to test unfortunately, but will leave that avenue for now. I'm running some compression tests as suggested above ...

Re: TF536 - Freeze on Disk Access?

@alenppc What are the specs and revision of your A500?

EDIT* And what memory chips + CPU in your 536?

Re: TF536 - Freeze on Disk Access?

lilwashu alenppc This does sound very similar to issues I've been having this week. The 536s are ostensibly fine with booting, WHDload games, demo loops, and all memory tests check out but copying large numbers of files either between partitions or within the same partition cause the machine to loc...

Wow! Hopefully You was prepared to see fireworks on power on, since these are four-layer boards. Cutting them may short out GND and VCC inner layers.. :shock:
Where's your sense of adventure?? :lol:

Re: Openflops floppy emulator

It's not a copied gotek. They silkscreened it because they produced it. So it has the same form factor, dimensions and mount holes as a Gotek, the same component layout as a Gotek, can run the same firmware as the Gotek and is based off the schematic from the Gotek, but it's not a copied Gotek? Wha...

Re: Openflops floppy emulator

If anyone knows more about who actually 'owns' the Gotek design then it would be interesting to hear....? At a guess this lot . Well if Gotekemulator did indeed design it, as their 'About Us' page alludes to, and they're clearly still selling it, then creating an Open Source version seems a bit dub...

Re: Openflops floppy emulator

That looks suspiciously like a 're-branded' version of https://github.com/SukkoPera/OpenFlops with no mention in the listing of where it came from, although I do see his name on the board silkscreen. I have no idea what the license situation is in terms of the 'real?' Gotek boards, if such a thing e...

Re: Length between the legs on MC68000 for Atari ST

I'm not sure I follow what you're trying to do. If you are using a common DIP64 68000 CPU for some purpose then the pitch will be 2.54mm / 0.1" , that is the socket you require unless you are doing something else?

Re: Length between the legs on MC68000 for Atari ST

Here is a 22.86mm 68000 DIP socket footprint in .pretty format for use instead of the standard version supplied in the Kicad footprint libs. All the spacings are standard but it uses smaller oval pads (X 1.5mm , Y 1.3mm , Hole 0.8mm) to allow additional room to route in between without being excessi...

mrgo0se_1984 ?!?!? ... wouldn't trust that cowboy to wire a plug let alone build an accelerator, I suspect he doesn't know one end of a soldering iron from the other! :lol: DX93 I will send out another card for you to try early this week.
