Jupiter Ace Orphaned

[bjjones37]

Since development on the Jupiter Ace has stopped, is there any chance some other developer could pick it up? I would really like to see some kind of file I/O on it.

I did not know that the core anyone ever used. So why work on it?

A few cores need some similar love, like the Apple II is missing disk writes.
I wonder if a common solution could be used across these cores?

That's not true. I tried your Jupiter ACE core and I was interested:

Luckly, I'm a happy owner of ZX-Uno where exists an awesome Jupiter ACE core:

Anyway, thanks a lot Gehstock for your great work making cores for MiST / Mistica FPGA16.

I think you won't find any similar disk interface as the Apple II's.

Maybe the Mistica makers would like to support you.

I first bought a MiST from Lotharek and it worked well... until... like so many others... the power connector broke. My replacement was a MiSTica as I will not buy another product from Lotharek.

A friend of mine resoldered the power connector and it works perfectly.

It's like scrapping your car because the mirror broke off.

Funny. No actually it isn't at all, I didn't throw it away but I also do not do any SMD soldering. One day, I may have it fixed... maybe not .. my choice. The point is that it should have been quality built in the first place, did I mentioned I only plugged/unplugged it maybe 5 times total before it broke?

I'm not here to protect Lotharek, but I'm using my MiST (version before the change to the THT micro USB connector) for more than 2 years, and it's still in place. However you can solder a barrel connector (there's even a Wiki page for it) to replace the micro USB, that would last until the world's end, no need to do any SMD work (ok, a little one to move a resistor).

In my opinion it's more the extremely small and fiddly electronic parts which are used these days and not Lotharek's skills. The "microelectronic" parts used back in the 70s-90s are huge from todays sight. A few months ago I used to work with a bare Raspberry Pi Zero W and while handling and connecting cables to it, my finger "wipes" a resistor (?) (too small to detect...it's smaller than 1mm) from the pcb, which was soldered on one edge. Damn, this was very difficult to resolder with my old scool tools. But had worked.

Said this I protect Lotharek's work and skills. Bought some MiST's, cables and many other parts there for my Atari 8/16 bit and everything is "industrial quality", as far as I can tell. And nothing broke or got faulty here since years.

You can install a power socket, you may find tricky to remove the 0-ohm SMD resistor, just desolder the old (R2) and make a shortcut with a wire (very short) on R1 -thats if you find tricky to mess with the SMDs

no mate, the issue with this fault is clearly "mechanical" there is no support on this connector,
its designed for mobile devices and usually is supported (on top) by a case or other PCB sandwich-like, in MiST's case its just soldered on the PCB and receives some strain when someone plug/unplug the microUSB, the "ideal" would be a mod on the case something (L shaped) to be positioned on the top of that thingy.

I had this issue, re-soldered the poo, then -as lesson learnt- I just left permanently the microUSB of the power cable there , I only plug/unplug the adaptor.

Okay, and learned something again. Never saw MiST's bare pcb with my own eyes.
As we're talking about I remember darkly to read something about this issue...with the hint to plug in the power/usb cable carefully... as one always should do. But yes, this issues should be fixed in newer revisions.

... But yes, this issues should be fixed in newer revisions.

a quick -future- fix is to make extra holes on the PCB then solder some kind of -extra- connector strain relief over the microUSB port, I wrote "extra" as there is already a kind of strain relief -sideways of the connector- but not enough to save it from damage. (I don't recommend ideas like glue/epoxy over it)
