Texas Instruments TI-99/4 Fixed
Defect:
Fix:
The problem are the pins oxidized of the power switch, i have sprayed R-11 and the problem it’s disappeared completely.
I left turned on the computer for more than 2 hours and i have made a 50 x power cycle (ON/OFF) and the problem is no longer appeared.
Note:
I thought there had to be a VDP RAM problem with a diagnosis made remotely without having the TI-99/4 in the laboratory.
To avoid using the lame RF modulator i have used a standard Commodore 64 composite cable that works very well with a NTSC composite video output.

SNDH archive v4.6 released - 345 new/updated SNDH files (437 subtunes) – (total 9893 tunes)
Ever since the birth of the Atari ST, different chip music formats have had different ways to use them. If you are coding a chip music player for the Atari ST you would have to use dozens and dozens of special ways to replay music.
But in the mid 90′s, BDC of Aura crew became tired of this inelegant system and decided to fix the issue once and for all. He then created the ‘SNDH’ file format. SNDH is actually the original songfile and replaycode with a header bolted on top of the music and replayer. The header has a unified calling interface no matter what type of chip music is hidden beneath it, and it has extended datas about the music.

Apple Computer 1, also known later as the Apple I, or Apple-1, was released by the Apple Computer Company (now Apple Inc.) in 1976. It was designed and hand-built by Steve Wozniak. Wozniak’s friend Steve Jobs had the idea of selling the computer.
The Apple I was Apple’s first product, and to finance its creation, Jobs sold his only means of transportation, a VW Microbus, and Wozniak sold his HP-65 calculator for $500. It was demonstrated in July 1976 at the Homebrew Computer Club in Palo Alto, California.

Pravetz computers
Pravetz (Правец in the original Cyrillic, series 8 and series 16) were Bulgarian computers, manufactured mainly in the town of Pravetz. Some components and software were produced in Stara Zagora, Plovdiv, and other Bulgarian cities.
The first Bulgarian-made personal computer, IMKO-1, was a prototype of the Pravetz computers that were developed by Ivan Vassilev Marangozov, who was often accused of cloning the Apple II. A few early models were produced at the ITKR (pronounced ee-teh-kah-reh, Institute of Technical Cybernetics and Robotics), a section of the Bulgarian Academy of Sciences. Industrial production in Pravetz started shortly after.
Pravetz computers were of major importance in the economy of the Comecon.
In October 2013, a privately held Bulgarian company claimed in their website to have the rights on the trademark and misleadingly announced that “Pravetz Computers are returning to market”. In fact, the company has no link to the original “Pravetz” computers known during the Soviet Era.

A new firmware and flashtool is availible for Sys-Check V2 series.
The new flashtool now supports both Sys-Check PCBs equipped with a SST39SF010A flash chip (V2.1 and V2.2). When you start the flashtool, it will ask you which version you have. To be absolutely sure, the flashtool shows a simplified graphic view of both versions. I think, everybody can handle it :)
Of course the flashtool (and all other documents) are written in german and english.
Also there´s a new firmware V1.4 out. This firmware can be used with ALL Sys-Check versions – also with the old V2.0 (without flash). Owners of the V2.0 must burn the 16 KB firmware image into a 27128 EPROM. All other please use the flashtool to update their Sys-Check.
V1.4 has this minor changes:
