What is DiagROM?

DiagROM is a diagnostic tool for the amiga computers.

And it is to be used on defective machines, trying to help no-boot situations etc.

You simply replace the Kickstart roms in the Amiga with the DiagROM. and when poweron. your Amiga will start a diagnostic software. It will try to dump info on the serialport (and actual menus etc aswell) while also trying on the screen.

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.

Relaunch64 is an IDE (text-editor) for C64 assembler-coding on Windows, Linux and Mac OS X. Relaunch64 has a clean and intuitive user interface, yet it offers many features that make coding faster and easier.

Java 7 or higher is required to run Relaunch64. The program is licensed under the GNU GPL 3 (or higher) and free for private and professional use.

This editor works together with common cross assemblers like Kick Assembler, ACME, or 64tass. Other assemblers might work as well, but syntax highlighting may not be 100% correct.

CBM prg Studio Version 3.9.0 is released. There are a lot of new features in this version. I’d really appreciate it if you report any bugs you find or have any suggestions/comments.

CBM prg Studio allows you to type a BASIC or Machine Code program in using a nice Windows environment and convert it to a ‘.prg’ file which you can run on an emulator, or even a real C64 / VIC20 or PET if you’re feeling brave and have the right kit.

CBM prg Studio is the result of merging C64PrgGen and VIC20PrgGen. Adding new features and fixing bugs in two apps which were 95% similar was a bit of a nightmare so merging them made sense.

It was also a good opportunity for a face lift and to add some new features, such as:

• Programs are project based, meaning all related source files, sprite files etc. are kept in one place and multiple source files can be linked more easily.
• Tabbed MDI.
• Syntax highlighting.

What CBM prg Studio isn’t is a front-end for tok64, cbmcnvrt, bastext or any other tokeniser / detokeniser / assembler. It’s all been written completely from scratch.

New features in v3.10.0:

• Assembler:
  • Increased sprite include limit to 256.
  • ‘Memory overwrite’ error is now a warning.
  • Use CTRL+[ and CTRL+] to go to previous/next label definition.

• Sprite Editor:
  • Added new functionality to scratchpad.
  • Functions can act over a range.

• Character Editor:
  • Rotate character 90 degrees.

• General:
  • Option to load last edited project automatically.

Bugs Fixed:

• General:
  • Using space(s) with screen code builder.
  • Wrong menu after creating a project.
  • Occasionally throws an exception when closing and opening the project explorer, project information and output windows.
  • ‘User’ palette settings not saved/used.
  • ‘User’ tools menu not created properly.
  • Generate and launch could use wrong filename.
  • VIC 20 memory configuration not set properly in emulator.
  • Tabs with different zoom levels would crash when changing tabs.

• Assembler:
  • Uppercase PETSCII chars not generated properly.
  • IncBin wrongly reporting file too large.
  • Floating point value 0.0 not generated correctly.

• BASIC:
  • Renumber not working for certain uppercase keywords.
  • Character code multiplier limited to 255.
  • Compress should ignore comment lines.

• SID Tool:
  • Incorrectly reporting that the tool was still open when quitting CBM prg Studio.

See the help for a complete list of new features and fixed bugs.

Note In this version, each target machine can have its own default project directory. If you are upgrading from a previous version (before version 2.5.1) of CBM prg Studio you may be asked to set up your project directories again. Your current projects will not be affected.

This computer is of a dear friend; Paolo Cognetti.

Short story of the repair:

I have checked the voltages and are correct, although a couple of capacitors on the power stage need to be replaced.

I have tried to turn on the computer and i have see immediately a problem, the screen is full of random characters, with the oscilloscope i have tried to see if i have data stream on the CPU (Z80), interrupts and so on.., nothing, it seemed completely dead, replaced.

The computer has started better then before but with some video glitches, raster lines scrolls from bottom to the top and some characters scattered on the screen. I double checked the voltages and i have realized that the 12v are gone and the 7812 warmed a lot, about 80 degrees after 2 minutes.

Almost all tantalum capacitors of 1uf and 33uF on the 12v line are shorted, i have decided to replace them all (22 pieces)

After the replacement of all tantalum capacitors and two electrolytic capacitors on the power supply stage the computer has started to work correctly but with some video problems, characters scattered on the screen, after replacing two Static RAM 2114 everything works perfectly, including the Basic Cartridge that until now had never worked.

Works that have been made:

• Fixing broken Fuse Holder.
• Fixing a cold welding of a capacitor on the power supply stage.
• Testing Voltages.
• Replaced CPU Z80.
• Replaced 12 x Tantalum Capacitors (1uf)
• Replaced 10 x Tantalum Capacitors (33uf)
• Replaced 1 x Axial Electrolytic Capacitor (470uf)
• Replaced 1 x Axial Electrolytic Capacitor (1500uf)
• Replaced 2 x NMOS 2114 Static Ram.
• Fixed the botton cover with two missing screws.
• Cleaning the top cover using only water and a sponge.
