Re: Reverse engineering the 6522 VIA chip?

IMO, all chips on eBay with sellers from Bulgaria are fine. They are remains after Pravetz 8D production was stopped. I don't see any reason someone to put effort and resources to fake exactly Oric's ULA expecting to sell no more than 2-3 pieces :). EDIT: If needed I can send some pieces "as sacrifi...

Re: Clock Signal — an Oric emulator for macOS and Linux

Thanks for the release, ThomH! I will try it definitely because I'm unable to create usable executable with XCode. Actually everything is compiled without errors/warnings, but when I try to start it I have just blank window. Maybe I have problem with missing ROM images at the right place... Thanks a...

Re: Oricutron for android (POC)

It's possible to be done entirely from Android, but the idea was to decompress on PC and then transfer ter APK to smartphone.

Re: Clock Signal — an Oric emulator for macOS and Linux



Confirmed! The problem is in the ported code.
In my test I used one very good floppy with perfectly tuned 300 rpm (i.e. 200.0 ms period).
I will add code that uses VIA's timer to measure the rotation period too.

Great work, ThomH!

Re: Clock Signal — an Oric emulator for macOS and Linux

Wow, this is great, Thom!
BTW, maybe there is no issue in your code - I ported the code from Apple and it's possible that the time-measuring routine gives wrong result because of clock difference (i.e. 1.000MHz vs 1.025MHz), let me check tonight with real hardware and I'll post the result asap.

Thanks for the small but very nice tool dsk2woz! I saw your announce on comp.sys.apple2 too :). It works well but ... back to Clock Signal - is currently Disk][ read-only or something with the write-protection switch is wrong? clk-writeprotect.jpg Attached archive contains DSK, NIB and WOZ images fo...

Re: Paste from clipboard problem

Yep, very bad OCR!
Attached is my version of the fixes (listing + tap).
Actually it the same as Chema's, but I'm posting it because I used exactly the same line number 2557 to add missing DATA - lucky coincidence ... :P

IMO everything looks nice and nothing suspicious.
Are this tracks OK or it's because the low resolution of picture:

You can check also if the insulator under the 7905 is firmly placed and doesn't short tracks.

Re: Paste from clipboard problem

Bas2tap will do the job! Else Oricutron's copy and paste functions should work too. My two suggestions for you: - try the latest unofficial build from here: http://iss.sandacite.com/oricutron/ (you can choose 32 or 64 bit). - try to paste the listing in smaller parts i.e. select 20-30 lines copy/pas...

Welcome, protek! I would start with the first one (which has sockets) - at least good text chars are visible. I tried my crystal ball but no insights... ;) Can you post pictures of the PCB and your power adapter (mainly its label with data about voltage and current). You measured 5V line and it's go...

Re: Orikai

The Orikai.exe is 32 bit, so you need the 32-bit dll. Try with the attached one.

Quick news if I type HIRES:POKE#21F,0:CLOAD"" then voilier_std_1.1g.wav works! Of course the hires screen has 'Searching...' just like ROM v.1.0 error :).
