Cosa sono le DiagROM?

Le DiagROM sono delle ROM diagnostiche per gli Home Computer della serie Commodore Amiga. Queste ROM tornano molto utili in alcune sistuazioni, tipo quando il computer non esegue correttamente il boot o si blocca.

Changelog:

• A lot of internal changes.
• But changed keyboardhandling in “Manual Edit” mode, hopefully keyboard works better now.
• Chipmemdetect at startup does more tests to capture more biterrors.
• Also added tests if CPU can do odd/eveb reads and writes. Request by Terriblefire.
• Added a testpicture as GFX Test
• Added test for RTC Chip, reads both types you have to know what chip is in your machine.
• Added a experimental Autoconfig support for Zorro II boards and memory, Remember that you can only run this ONCE.
• Autoconfigcode is based on Terriblefires code with addons by me.
• Audiotest now includes several notes and waveforms and also a module.

Updatehistory:

• 2017-04-15: Added Support for OKI Chipset in RTC Test
  • Added (somewhat experimental) support for Autoconfig for Z2 boards.
  • Must say thanx to Terriblefire for autoconfig code. (with some changes by my)
  • Added test at startup to see if CPU can do odd/even byte read and writes
  • Bumped version to V0.9 – Next Stable release
  • Released while being at the Revision demoparty.
• 2017-02-25: Moved mainmenu alternatives to make space for more maintest-menus. also added some for future use.
  • Started on Others tests/RTC Test for the moment only showing ricoh RTC chip (A4k etc)
  • Removed temprary debugfunction added the 18:th.
• 2017-02-18: Minor changes. sometimes when exiting a testscreen you got to the mainmanu instead of the submenu. cleaned up now.
  • also added a fakefastmem allocation at the boot so you can run stuff in fakefast by pressing LBM at poweron if needed.
  • TEMPORARY DEBUGFUNCTION: while dumping serialport at beginnning, screen also flickers while doing a serial timeout.
  • this is to figure out if machine still runs to veryfy I can do serialstuff (and detect failures) if paula is missing.
  • will be removed soon as it screws up onscreen colorcodes.
• 2017-02-15: Added a testpicture, testscreen is moved in menu and will still bug. this will be reworked soon.
• 2017-02-04: Simple audiotest is now improved, it now plays different waveforms, I have checked the frequencys with my Rigol scope.
  • But 20.6Hz in my headphones sounds weird, maybe should remove it in the test. the only thing not working there now is setting volume.
• 2017-01-30: In Manual edit: added when using “goto memoryaddress” when pressing x it clears the string totally. Also hopefully fixed keyboardbug making
  • it more or less impossible to use keyboard on some machines.
  • Fixed bug showing strange flickering spritebugs random
  • Changed that in initial chipmemdetecting it checks more combinations of bits, this will make detect slower (due to serial output) but will detect more
  • biterrors.
  • TEMPORARY function: pressing fire/mousebutton in joystickport while poweron will totally disable serialoutput. this is to be able to run with broken
  • Paula. Will look into a better solution. so function will maybe be removed.
  • Added a testmodule, A groupmember will make a chipmodule for me later to have here. Now using the classic “Echoing”
• 2017-01-06: Long time since last update. Hollidays etc. Anyway some minor internal fixes and a basic low-res testscreen added.

L’interfaccia ‘HxC Floppy Drive Emulator‘ è un sistema hardware e software creato da jfdn aka Jeff.

L’obiettivo di questo progetto è quello di sostituire l’unità floppy disk con un dispositivo elettronico che emula il floppy drive (lista dell’hardware supportato).

Esistono due interfaccie di emulazione:

• Una versione USB che permette di collegare l’interfaccia floppy disk drive del computer a un PC tramite un cavo USB.
• Una versione SDCARD che permette di emulare i floppy disk tramite le immagini memorizzate su una SDCARD.

Release notes for the HxCFloppyEmulator software v2.1.6.0:

• XML format definitions : Korg DSS1 DD disks added.
• XML format definitions : Emax II disks added.
• Command line tool : USB loader -> Raw loader added.
• Amstrad DSK file added to the batch converter export list.
• New Writer : Thomson *.FD writer.
• Thomson *.FD loader fixed : Side 1 ID corrected to 0.
• D88 Writer fixed : Cylinder and Side ID correctly set.
• ImageDisk (*.IMD) export : Deleted data mark and data CRC error flags supported.
• FAT12/16 Disk browser : Entries First cluster readback corrected. (With high word uninitialized).
• IMG loader : More disk sizes support added.
• DosDiskBrowser : 1.743MB & 1.764MB added.
• 64bits systems : Batch converter and Dos Disk browser issues fixed.
• MacOS X & Linux version : file export -> Auto-append the file extension.
• Track editor : Disk flux stream reverse function.
• Track viewer & editor : GUI layout changed/updated.

Le DiagROM sono delle ROM diagnostiche per gli Home Computer della serie Commodore Amiga. Queste ROM tornano molto utili in alcune sistuazioni, tipo quando il computer non esegue correttamente il boot o si blocca.

Updatehistory:

• 2016-10-22: Fixed bugs in new Chipmemdetection that made it not detect any chipmem if there was missing/Broken chipmem in the beginning. Added errorhandling in the startprocess, so it can show on serialport if there was a exceptionerror. also will show colorcodes on screen. done some smaller bigfixes. Will bump versionnumber and this will be the stable version. It will take a while until next stable version is bumped. Need to do floppy, serial, paralell tests etc before that will happen. but you always have the daily version.
• 2016-10-12: New Chipmem detection now handles shadowram so it should stop detecting memory instead of giving false 2MB Chip. IF no Chipmem avaible and machine can detect fastmem (NON autoconfig. more or less only A3000/4000 motherboardmem) it will now start using fastmem only. (screen flickers in different colors instead of printing text, nullmodem only) Fixed addresserrorbugs at CIA and joystickport tests on machines with 68000CPU. also should have correct CIA timing on slow machines. IF fastmemshadowram is detected during memorytests, test will exit. MANUAL test have a option to disable that test.
• 2016-10-07: LONG time no updates. Familystuff. Anyway. decided to do a total redo of initcode especially chipmemdetection. Detection is slower, but progress is printed on serialport so you can see address checked and if failure (in the beginning of the detection) you will see what it wrote and what is read to help debugging of chipmemproblems. Screen should flicker in green while detecting. drawback is that some tests (cia and joyport tests) now generates an addresserror. Will have a look of that.

Assemblaggio e Sostituzione del vecchio DualSID con il MixSID.

A differenza del DualSID ho dovuto sostituire i due condensatori elettrolitici (vedi foto) perche’ il PCB del MixSID e’ molto piu’ largo e i due condensatori impedivano la corretta installazione del PCB nello zoccolo del SID.

Per le caratteristiche tecniche del MixSID andate qui
