Stella release v3.8.1 for Linux, MacOS X and Windows is now available.

Changelog:

• Added support for TIA RSYNC writes, thanks to Omegamatrix of AtariAge. This allows the recently released “Extra Terrestrials” ROM to run, as well as improving emulation of “Fatal Run” and several other test ROMs.
• Fixed typo in TIA HMOVE writes, thanks to Thomas Jentzsch. This fixes the constant collision issues in “Kool-Aid Man”, and several other homebrew ROMs.
• Fixed sound issues on OSX PPC machines (all sound was in little-endian format, but PPC is big-endian).
• The OSX DMG archive now contains proper modification dates.

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.

Current supported machines:

• C64.
• C64DTV.
• Vic-20 unexpanded.
• Vic-20 +3K RAM.
• Vic-20 +8K RAM or plus (for FE3 use this version)
• Vic-20 with Mega-Cart.
• C16 / C116 / Plus4.
• C128 in 64 mode.
• C128 80 Columns.

Changelog:

• v.0.1 – 01-Sep-2009 (Start of project, C64/C64DTV only)
• v.0.2 – 21-Oct-2009 (First working version for Vic-20 +8K RAM)
• v.0.3 – 06-Jan-2010 (Added memory config auto-detection for Vic-20 selected program)
• v.0.4 – 19-Jan-2010 (Added support for Vic-20 with Mega-Cart and manual start mode)
• v.0.5 – 10-Feb-2010 (Added support for Vic-20 unexpanded and Vic-20 +3K RAM)
• v.1.0 – 05-Mar-2010 (First public version, minor issues fixed, C64 and Vic-20 supported)
• v.1.1 – 22-Jun-2010 (Added support for D41 and DNP file images, sd2iec firmware v.0.9.0 or higher required)
• v.1.2 – 09-Oct-2010 (Added SJLOAD speed-up option to the manual mode of the Mega-cart version)
• v.1.3 – 31-May-2012 (Added support for C16/C116/Plus4, Sort directories, cosmetic changes)

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!

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.
