Macintosh SE/30 Fixing Motherboard Faults.
I spent many months (eight) to repair some of these macintosh SE/30 motherboard, like you can see in the gallery.
The flaws that i could find and repair are:
- Some multiplexers (74F253 or like) burned.
- Some Video Ram burned.
- Very Dirty Motherboard.
- Electrolytic capacitors have to be replaced.
- Reseat the RAM and ROM SIMM.
- Some track of the PCB broken or corroded by the acid.
- Replaced the lithium battery with a new one.
- Cold solder joint on chip: RP4/RP5/RP6 – UI2/UI3/UI4 – UJ2/UJ3/UJ4
The flaw that you see in the first picture and that should be the “Jail Bar Pattern” or “Smile Mac in Jail”, in this case is not been so. For this reason i spent a long time to find the fault.
However, i recovered 3 motherboards and I consider myself quite satisfied.

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 or VIC20 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.

Exomizer is a program that compresses files in a way that tries to be as efficient as possible but still allows them to be decompressed in environments where CPU speed and RAM are limited. For some popular 8-bit computers using 6502 compatible CPUs it can also generate executable files that decompress themselves in memory when run.
- 2011-08-19: Exomizer v2.0.2 released
Changes since the 2.0.1 release:
- Added 6809-decruncher contributed by Edouard Forler.
- Fix language errors in the documentation. Thanks to Csabo/LOD.
- Remove bogus printout about the default decrunch effect when using a custom decrunch effect. Bug reported by Csabo/LOD.
- Fix bug that prevented the correct error message from showing when trying to combine a basic start and a non rom config for the sfx command. Bug reported by iAN CooG.
A complete changelog is included in the zip file.

VirtualC64 emulates a Commodore 64 personal computer on your Intel Macintosh OSx > 10.6.
I wrote the software with two major goals in mind. First, I wanted to create an emulator that can be used as a demonstrator program in a first year or second year course on computer engineering.
To achieve this goal, I have integrated various debugging capabilities that let you peek inside the CPU, RAM, ROM, or one of the custom chips. Second, I tried to make the emulator as user friendly as it can get.
In short: VirtualC64 tries to combine the ongoing fascination of the ancient Commodore computers with the great user experience of today’s Macs.
Bug fixes and enhancements:
- Fixed another bug that caused the emulator to crash on some lion machines.

Kick Assembler is the combination of an assembler for doing 6510 machine code and a high level script language.
Kick Assembler comes with an exe file so you don’t need to install java. The jar file is still distributed – we will keep supporting all java compatible platforms (Linux/Osx).
8/8-2011 : New beta release (v3.19) – The LCP Release:
- You can now use the questionmark if notation in expressions. Eg. .var x = a
- Added a fillbyte option that sets the byte used to fill the space between memoryblocks in the prg file. Usefull for writing a eprom or flash (I’m told, hope you can use it Alex :-)
- You can now cast values to a numbers or strings by using the .number() or .string() function. Eg x= 1234.string().charAt(2) – sets x to 3
- Chars now have the same functions as numbers (+,-,*,,
- Made a quick reformatting of the manual since my new version of word had thrashed the layout.
