Re: Oricutron memory access breakpoints

Yesterday Hialmar uploaded the newest Windows WIP build on:

http://www.petergordon.org.uk/oricutron ... 32_WIP.zip
In this version "Oricutron memory access breakpoints" should work ok.

Re: Oricutron with serial port emulation

I checked TeaForTwo converted to DSK and it hangs exactly as HNEFATAFL-ONLINE disk version. Then checked the comm routines and didn't found anything suspicious. Fortunately, I found a workaround - when building in osdk_build.bat use: %OSDKBIN%\tap2dsk.exe -i" !QUIT: !HNEFATAFL" BUILD\HNEFATAFL-ONLIN...

Re: Cumulus replacement ?

IMHO, it will be NOT simpler. All links are for floppy emulators only and in this part Cumulus works well. The problems are related to the connection with the system bus and I think this can be fixed even without changes in current Cumulus hardware. Last but not least - many people are happy with Cu...

Re: Cumulus Issues

@Godzil: Correct this fixes: DBG2 undefined bug.
EDIT: After playing with some "FIT" relater options I succeeded to generate Cumulus.jed file. There still 4-5 warnings but I think it's normal.
After we test this Xilinx file will post the results!

Re: Cumulus Issues

@coco.oric: You said "mplab suite" - probably you mean the firmware for the PIC - yes, it can be compiled fine. We have problems with compilation for Xilinx i.e. the sources here: http://miniserve.defence-force.org/svn/public/oric/hardware/cumulus/cpld/ We found 2 errors in 'Cumulus.VHDL': line 62: ...

Re: Cumulus Issues

Does anyone have news from metadata? His last visit here is 2014.08.07. I hope he's doing fine! I'm asking because with jorodr we have 2 broken Cumulus which we want to fix, but we have issues with Xilinx sources compilation - any help is appreciated! PIC, EEPROM, displays, bus, cables are separatel...

Re: Oric Atmos query

I'm glad I was able to help. :D
Else think twice before start mass-desoldering - it's really risky.

Re: Oric Atmos query

Totally agree with Godzil and when it comes to be 'gentle' here is what I do now: Atmos.jpg This is/was Atmos with the same power-on problem but I decide to desolder all chips and place sockets. Important for me is to preserve the board but careful and gently I succeeded to preserve the chips too. I...

Re: Oric Atmos query

C21 is important for RESET signal else replacing all electrolytic capacitor is good idea.

Re: Oric Atmos query

I have the same issue with an Atmos I recently bought.
Exactly as you said - it's very temperamental or 'temperature-mental' :).
One easy thing you can do is to replace the capacitor C21 (1uF) with new one.

Re: Oricutron with serial port emulation

Congrats, barnsey123!
Nice work, it's playable and fun. Thanks for your effort.

Else, I can confirm DSK is not working, but TAP is perfect.

Re: Replic'Oric

And one more thing: What about using (UV)EPROM instead of PROM? I mean pin 27 /PGM - would it work as expected with microdisk in regard of ROMDIS signal?
