I have received a Commodore Amiga 500 to use as spare parts. I decided to restore because it’s a ASSY 312512 (Revision 3) with key-switch like IBM chiclet keyboards.
The cleaning took me a whole day but with a great satisfaction at the end of the work. The Commodore Amiga 500 works fine, the floppy drive reads very well and i have added a memory expansion (FAST RAM) of 512k.

Tomasz “Tebe” Biela has released an update of the program Graph2Font v3.9.9.3 and the Atari Graphics Studio v2.9.9.
This project began many years ago as a simple graphics converter for Atari but over the years the features are significantly increased. The converter runs under Windows.

I received the Texas Instruments Expansion System (PEB) from a dear friend.
The Texas Instruments Expansion System (PEB) although fully functional, needs a restoration, for example; some parts of the top and bottom cover are rusty.

I thank my dear friend Ciro (www.ti99iuc.it) for giving me the “Peripheral Expansion System” and for making me discover a whole new world of the Home Computer Texas Instruments TI-99/4A.
Gallery:
The Peripheral Expansion Box (aka P-Box or PEB) is a stable, silver/gray plastic and die-cast metal box containing eight slots for peripheral expansion cards and a compartment for a floppy drive or two drives of half height (“slim-line”, slim as understood in the 70ies and 80ies; today it is the normal height of 5,25″ drives for PCs).
The PEB offers space for 8 expansion cards. All slots are wired in parallel, and the power supply is designed to supply all cards including up to two floppy drives. Floppy drives may be put into the right compartment of the box.
With the appearance of hard disk controller cards, users tried to mount hard drives into the box into the floppy compartment. However, the power supply is not designed to sustain the current required for the hard drives; thus, a separate power supply is recommended.
All peripheral cards are expected to provide their own voltage regulators. Therefore, it is not recommended to replace the power supply by today’s PC switched power supplies, as those already provide regulated power which may cause the regulators on the cards to lower the voltage below the acceptable range.

Commodore Amiga 600 (Black Screen) Repair
Defect:
Replaced parts:
- 4 x Electrolytic Capacitor 10uF 35v
- 2 x Electrolytic Capacitor 22uf 35v
Note:
The Amiga 600 Motherboard looks in good conditions; no traces of a acid leakage from capacitors, as usually happens on Amiga 600/1200/4000, but all had a too high ESR (Equivalent Series Resistance).

CBM prg Studio Version 3.2.0 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:
- PTEXT and NULL directives.
- NULL added to GenerateTo directive.
- Colour printing.
- Source overview.
Bug Fixed:
- Assembler:
- Reformatting code.
- Some arithmetic problems with variables.
- Basic:
- Some screen code fixes.
- Renumbering TRAP keyword (BASIC 3.5 & 7)
- Mixing upper/lower case in DATA statements.
- Wrong load address for some C128 BASIC projects.
- General:
- Better support for Turkish language.
- Wrong toolbar shown after start-up page.
- Case sensitive auto-complete
- Problems with the build events.
