ZX Microdrive
The ZX Microdrive was a magnetic tape data storage system launched in July 1983 by Sinclair Research for its ZX Spectrum home computer. The Microdrive technology was later also used in the Sinclair QL and ICL One Per Desk personal computers.
Microdrives used tiny (44 × 34 × 8 mm including protective cover) cartridges containing a 5-metre (200-inch) endless loop of magnetic tape, 1.9 mm wide, driven at 76 cm/second (30 in/second); thus performing a complete circuit in approximately 8 seconds. The cartridges held a minimum of 85 kB when formatted on a ZX Microdrive (exact capacity depended on the number of “bad” sectors found and the precise speed of the Microdrive motor when formatting). The data retrieval rate was 15 kB/s, i.e., 120 kbit/s. It was possible to “expand” the capacity of a fresh microdrive cartridge by formatting it several times. This caused the tape to stretch slightly, increasing the length of the tape loop so that more sectors can be marked out on it. This procedure was widely documented in the Sinclair community magazines of the 1980s.
ZX Interface 1
A peripheral from Sinclair Research for its ZX Spectrum home computer, the ZX Interface 1 was launched in 1983. Originally intended as a local area network interface for use in school classrooms, it was revised before launch to also act as the controller for up to eight ZX Microdrive high-speed tape-loop cartridge drives. It also included a DE-9 RS-232 interface capable of operating at up to 19.2 kbit/s — a rare instance of Sinclair using an industry-standard connector. At hardware level it was mainly a voltage adapter, the serial protocol being implemented in software by bit-banging. This led to problems when receiving data, but not when transmitting.
A wedge-shaped device fitting underneath the ZX Spectrum, ZX Interface 1 contained 8 kB of ROM comprising the control software for the Microdrives, RS-232 port and network interface. This extended the error handler in the Sinclair BASIC to allow extra keywords to be used. As this became an official standard, other developers quickly used this mechanism to create language extensions to Sinclair BASIC.

This program works as a program launcher for Commodore machines. Even if it was originally intended for a device with sd2iec firmware, it works also with any CBM drive (without sd2iec functions of course).
It is a multi-system version derived from the discontinued sd2brwse v.0.6 by Hannu Nuotio (fork() of sdbrowse v.0.7)
The Vic-20 Mega-Cart Installer is based on sys.asm sources of mega-tools by Daniel Kahlin, sort routine by Michael Kircher.

- v.1.3 – 31-May-2012 (Added support for C16/C116/Plus4, Sort directories, cosmetic changes)
- v.1.4 – 19-Jul-2012 (Added JIFFYDTV speed-up support for C64-DTV, Clear screen before RUN)
- v.1.5 – 03-Mar-2013 (Added support for C128, and uppercases disk images D64,D81,D71 etc.)

A few things to repair for a friend.
- Enterprise 64
- Archimedes 310
Defect: unknown.
I have repaired an Atari 800XL for a friend. The failure was caused by a faulty cpu, the computer freezes after 10 minutes of operation, using an oscilloscope i have noticed that the clock pin of the cpu did not give me more signal but when i have used the synthetic ice spray on the cpu has resumed to work.
This type of cpu (Atari customized 6502 – C014806-12 Sally) is not easy to find but fortunately a friend of mine (Carlo) has found a spare part for me.

Jump here for the commercial RGB mod for the Mattel Intellivision
I have found this RGB mod for the Mattel Intellivision console fom a site, i have searched on the net if anyone has tried this mod, but nothing, so, i have tried to do it myself.
This mod is not easy to do, especially if one has no experience in electronics, however the result at the end is spectacular.

One smart ape has escaped from his cage. Mario, the zookeeper, is in a real fix! The gorilla Darwin has captured a very special lady and made his way onto a construction site and up bewildering, unfinished structures and a veritable King Kong! Leap for your life over bouncing barrels, ride fast-moving platforms to dizzying heights, scurry under runaway springs, and avoid roaming flames and dangerous balls of gas as you make your way up. It will take not only Mario but one of his brothers Toni and Bruno to outsmart the big ape and return the girl to safety.
It’s TWO games in one! The first arcade game, PLUS a second game with five all NEW levels inspired by the arcade hit D2K: Jumpman Returns! 9 Screens in total!
Features:
- New graphics and sound effects. Hear DK growl for the first time!
- Separate high scores for Game 1 and Game 2. Perfect for high-scoring competitions!

I’m happy to share the photos of the day spent with Damiano (Manosoft) that besides being a good friend is also the father of the interface C64SD Infinity for Commodore 64/C16/VIC20.
We spent a pleasant day of old memories, we are watched and commented some demos for the Commodore 64 and we have completed the repair of the keyboard of his Commodore SX-64.
Thanks Damiano for making me visit and for giving me a lot of things that are now part of my collection.

from Denial Wiki Homepage:
The VIC-1020 (known as the VC-1020 in Germany) expansion chassis is a large metal enclosure which provides the VIC-20 computer with six additional expansion slots for cartridges (five pointing upward and one lying horizontally and pointing toward an opening on the the back of the VIC-1020). The entire VIC-20 computer is placed into the VIC-1020 and a male edge connector on the 1020′s slot expansion board is mated with the VIC-20′s internal cartridge port. A monitor can be placed on top of the VIC-1020, giving the entire setup a PET computer-like appearance. Indeed, the black “CBM” label across the front of the VIC-1020′s casing is similar to that used on the the PET line of computers. The choice of sheet metal for this enclosure seems natural, as Commodore had a sheet metal fabrication plant for the production of office filing cabinets and desks.
The VIC-1020′s chassis has additional storage space which can be used for the computer’s power supply (a pass-through for the power supply is provided). There is also a metal clip on the underside of the lid which can hold the RF modulator.
Slot expanders such as this allowed the simultaneous use of several cartridges on a single VIC-20. This allowed features of utility cartridges (like the Programmer’s Aid cartridge) and RAM expanders to be combined. Unlike some other slot expanders, however, the VIC-1020 lacked switches to enable or disable individual cartridges – meaning cartridges had to be physically removed to disable them. This emphasizes what seems an apparent design flaw of the VIC-1020; the monitor needs to be lifted off the chassis and set aside to enable the user to open the lid and access the extra cartridge ports – a cumbersome process if repeated often.

from wiki.intellivision.us Homepage:
The Intellivision directly generates composite video using the AY-3-8915 Color Processor and a set of resistors. This video gets fed to the ASTEC UM1285-8 video modulator for conversion to RF for display on a television set. It is possible to tap this composite video directly to avoid the distortion and static associated with RF modulation and demodulation. On older units, the RF modulator can decay rather noticeably, leading to very low quality video.
Typical composite video inputs have an input impedance of 75Ω. In contrast, the composite signal generated by the Intellivision has a very high output impedance. (We estimate the output impedance is around 2KΩ.) Tapping this output and feeding it directly into a typical composite monitor does not work. (It will work if your monitor has a “high impedance” input, but such monitors are atypical.) Thus, an amplifier/impedance matching circuit is necessary.
It is also possible to tap the audio the Intellivision generates. The audio output by the Intellivision is nearly directly suitable for feeding line-level inputs on most AV equipment. All that’s required is a coupling capacitor.
The modification should work equally well on all Intellivision variants, including the Intellivision 1, Intellivision 2, the various rebranded units (Sears, Tandy), and the later INTV releases.
