The Multi-cart by Rolo was designed to to hold a variety of Dragon 32-64/CoCo 2 rom cartridge based programs, which are running directly from the eprom at address range $c000 to $ff00.
The cart holds up to 64 8k-roms. It can play roms with a size of 1k to 16k. You simply select a memory slot from 00 to 63, press RESET on your Dragon, and the program launches.
This enables you, to use your Dragon simply without further hardware setup: no cables, no drives, no extra PSUs, no controller-carts.
The Dragon/CoCo 2 Multi-cartridge now can also be used for other systems.
Currently there are three Extension Cartridges (adapters) available:
- VECTREX.
- Odyssey 2/PHILIPS G7000/G7200/G7400.
- INTERTON ELECTRONIC VC 4000.
A compilation of rom-files for all four systems can be burned on a single eprom (27C4001), adding versatility to the device.

Conversion Amiga 500 REV 8A (512k Chip RAM) to 500+ (1MB CHIP Ram)
Some Amiga 500 sold at the end of 1991/beginning of 1992 have a motherboard of an Amiga 500+ but limited to the capabilities of a regular Amiga 500 with 512k of Chip RAM.
These motherboards can be converted to 500+ simply installing the missing pieces; RAM section and REALTIME CLOCK.
What i did is add a 512K to have 1MB of Chip RAM like the amiga 500+.

Hyperkin Supaboy S – RGB/Svideo HACK
I have decided to make this hack because the native video output of the Hyperkin Supaboy S is really bad, uses the composite video.
The photos with the LCD monitor use the SVIDEO output while the photos with the Sony CRT monitor use the RGB output.
The photos and the schematic describe very well the work that needs to be done, the hack is not complex but you always have to be makes particularly attention to the SMD (CXA 1645M) side welds.

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.

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: 
+ many more….
Release notes Firmware USB HxCFloppyEmulator v3.0.20.1a:
- Low level I2C & LCD IO redesigned and optimized.
- Long names are now scrolling on the LCD during floppy emulation.
- Short name image type identification issue fixed.
- USB “Hot plug” support fixed in autoboot/”file selector” mode.
- Fix the config file access error when the file haven’t the archive flag set.
