Sorry, this entry is only available in Italian.

The Home Computer Asem AM 100 is a clone of the Apple II+ (Apple // Plus). This computer was manufactured and assembled by ASEM S.p.A. Artegna (UD) / Italy.

The AM 100 is fully compatible with all the software available for the Apple II and II+. I have personally tested many programs and i’ve never found problems of compatibility.

Unfortunately this computer is arrived faulty, the repair was more simple than i expected, thanks to the IC sockets located on the computer motherboard.

Works that have been made:

• Replacing IC 74LS161 which shows a vertical band on the screen.
• Removing RIFA filter capacitor located inside the PSU.
• Regeneration of the Keyboard PAD. Some keys did not work properly. The Keyboard PAD have been regenerated using a suitable product that can be found for sale on eBay. Try: KEYPAD FIX
• General cleaning of the case outside/inside, monitor and keyboard.
• EPROM dump.

All these works are documented with photos that you can find below.

Interesting discovery:

Inside the Floppy Drive reader (Apple clone) i have found the same mechanics (Mistumi / Newtronics) of the Commodore Floppy Drive 1541. See the first three pictures of the gallery: Under the cover.

Forth, the Language.

Forth is a different language. It’s aged and a little weird.
What’s cool about it? It’s a very low-level and minimal language without any automatic memory management. At the same time, it easily scales to become a very high-level and domain-specific language, much like Lisp. Compared to C64 Basic, Forth is more attractive in almost every way.

It is a lot more fast, memory effective and powerful. Compared to C, specifically cc65, the story is a little different. It’s hard to make a fair comparison. Theoretically Forth code can be very memory efficient, and it’s possible to make Forth code that is leaner than C code. But it is also true that cc65 code is generally much faster than Forth code.

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.

Jean-François DEL NERO (who’s behind the HxC SD Floppy Emulator) recently has released a version of the HxC emulator firmware that is compatible with the STM32 chip used in the Gotek floppy emulators.

This means that the great functionality of the HxC SD emulator is now available on cheaper and more widely available hardware.

The bootloader to convert the Gotek floppy drive in HxC compatible must be purchased on the website HXC 2001 by sending an email to Jean-François DEL NERO. The price of the bootloader is one-off 10 Euro per Gotek that you want to update. Future updates of the software are free and can be made from a USB stick

The HXC Usb (Gotek) firmware supports:

CBM prg Studio Version 3.5.0 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.

Improvements:

• Assembler:
  • Fragment assembly.
  • Debug directive.
  • Easier label exporting.
  • Custom character mapping for TEXT directive.

• General:
  • Overlap detection when building mixed BASIC and Assembly sources.
  • Generate and Launch doesn’t rebuild the source if no changes have been made.

Bugs Fixed:

• Assembler:
  • Better error reporting for invalid WORD values, specifically with arithmetic.
  • TEXT strings containing ‘;’ characters were truncated.
  • Crash when dragging text around a source file.

• Debugger:
  • SBC instruction not setting/clearing carry flag properly.

• BASIC:
  • Statistics tool not coping with ‘rem’ in strings.

• General:
  • If the confirm quit dialog is turned off and changes have been made there is no save option.

A new version of the firmware for the interface 1541 Ultimate II is released. This version runs only on the 1541 Ultimate II cartridge (new fpga).

Release notes 3.0 beta 5:

Major:

• BUGFIX: Processor’s Data Cache stored result of IO read, causing wrong values to be read from the cache

Minor:

• C64 Keyboard scan made a bit slower  (not tested)
• Fixed configuration drop down
• Fixed clock settings
• Mount disk made first option in D64 file type
• Updated Final 3 cart.

Release notes 3.0 beta 4 (first version released on Facebook):

• The FPGA platform has gotten an upgrade. There is now a faster RISC processor on board (~10 times faster), and I have re-written the USB host controller, which has become ~50 times faster. The external memory of the FPGA also runs faster, and delivers now also approx. 7 times more bandwidth. With this faster platform, it has become possible to run a multithreaded OS.
• There is now support for USB2LAN adapters, and 3.0beta4 runs two services: a (raw-)telnet (VT100) server that brings up the menu, and an FTP daemon for basic file transfer.
• There is now support for reading the directories of D71 and D81 files in the browser.
• There is a ‘CD’ command in the software IEC, and other improvements have been made to the soft IEC driver.
• There is now a copy command in the file browser, that works with C=C/C=V (or CTRL-C / CTRL-V). It is not that fast, but for small files it works. You can also copy files from inside a D64/T64 to another location in the file system. The other way around is still under development, but will soon be possible as well.
• UltiCopy is disabled for now, because it still needs to be ported to the multi-threaded operating system.
