The RGB cable of  Schneider (radiola/philips) VG-5000 computer is compatible with the VideoPac G7200.

from Wikipedia:

The Magnavox Odyssey², known in Europe as the Philips Videopac G7000, in Brazil as the Philips Odyssey, in the United States as the Magnavox Odyssey² and the Philips Odyssey², and also by many other names, is a video game console released in 1978.

In the early 1970s, Magnavox was an innovator in the home video game industry. They succeeded in bringing the first home video game system to market, the Odyssey, which was quickly followed by a number of later models, each with a few technological improvements (Magnavox Odyssey Series). In 1978, Magnavox, now a subsidiary of North American Philips, released the Odyssey², its new second-generation video game console.

In Europe, the Odyssey² did very well on the market. In Europe, the console was most widely known as the Philips Videopac G7000, or just the Videopac, although branded variants were released in some areas of Europe under the names Philips Videopac C52, Radiola Jet 25, Schneider 7000, and Siera G7000. Philips, as Magnavox’s Dutch parent company, used their own name rather than Magnavox’s for European marketing. A rare model, the Philips Videopac G7200, was only released in Europe; it had a built-in black-and-white monitor. Videopac game cartridges are mostly compatible with American Odyssey² units, although some games have color differences and a few are completely incompatible. A number of additional games were released in Europe that never came out in the US.

This is a firmware hack of the version 2.6d build for the 1541 Ultimate Plus (MK1) by Bradon (forum link).

The latest official version for the 1541 Ultimate Plus (MK1) is the version v2.4a.

Note from the author:

After much frustration, I finally managed to get a working build environment for the 1541U firmware.

My 1541U is a MK1 Plus unit (no network). The last revision of the firmware I could compile is 2.6d, SVN revision 131. Starting with 132 it seems that the content is too much for the older FPGA. I started to look into removing cart ROMs I don’t use and gave up realizing this would be too much to do in my spare time, since their offset locations are hardcoded.

I removed the “too old” warning check so it will boot up without having to dismiss a warning.

So far it seems to work correctly. I don’t know if the FPGA revision check really matters for this revision or not. It would appear Gideon has no desire to continue supporting MK1 units since building for them is not possible with the latest revisions. This is of course fine with me (I don’t expect he will forever and ever try to make it work on older units), I just wanted the most recent build possible.

Changes:

• Added F3 help screen to show 1541U commands.
• Modified the file viewer so that scrolling will not advance past the last line.
• Added F1 and F7 page up/down to the file viewer.
• Modified behavior of the file browser so that when you cursor-right on an item with no children, the context menu is brought up as if you pressed return.

How to write the .DSK files to Floppy Disk for the Sharp MZ-80B ?

The answer is quite simple, first of all there you need an old computer with harddisk with installed the operating system DOS/FreeDOS and a Floppy Drive 5¼. The tool to use is the CPDWrite (Copy Protected Disk Writer) v1.03 and some floppy disk image in .DSK format for the Sharp MZ-80B.

Below you can download the archive containing many floppy disk in .DSK format and the utility to write files on Floppy Disk.

The original archive was downloaded from this web page, but unfortunately the only one floppy disk that seemed to be more interesting ‘DISK15.DSK’ containing the games for this computer was corrupted. I found the problem and i have fixed with the use of a hex editor, the fixed version was included in the archive.

from Wikipedia:

The Sharp MZ is a series of personal computers sold in Japan and Europe (particularly Germany and Great Britain) by Sharp beginning in 1978.

Although commonly believed to stand for “Microcomputer Z80″, the term MZ actually has its roots in the MZ-40K, a home computer kit produced by Sharp in 1978 which was based on Fujitsu’s 4-bit MB8843 processor and provided a simple hexadecimal keypad for input. This was soon followed by the MZ-80K, K2, C, and K2E, all of which were based on 8-bit LH0080A Sharp CPU (compatible to Zilog Z80A) with an alphanumeric keyboard.

From the first Z80 processor-based model to the MZ-2200 in 1983, the MZ computers included the PC, monitor, keyboard, and tape-based recorder in a single unit, similar to Commodore’s PET series. It was also notable for not including a programming language or operating system in ROM, like the IBM PC. This allowed a host of third-party companies, starting with Hudson Soft, to produce many languages and OSes for the system. In an era when floppy disk drives were too expensive for most home users, the MZ’s built-in tape drive was considered faster and more reliable than the drive on competing computers; however, this meant that the MZ series was relatively slow to adopt floppy drives as a standard accessory.

The MZ series is divided into several lines, including the text-based MZ-80K series, the graphics-based MZ-80B series, and the MZ-3500/5500 series, based on a completely different architecture. In 1982, Sharp’s television division released the X1, a completely new computer. The X series proved to outsell Sharp’s own MZ series, and in response, Sharp released the MZ-1500/2500 machines, which featured powered-up graphics and sound capabilities. However, this series saw little marketplace success, and eventually the company abandoned the line in favor of the X68000 series.

The MZ name lives on as the initials of two of Sharp’s most well-known products: the Mebius line of PCs, and the Zaurus line of personal digital assistants.

Commodore CBM 8032 fully functional but without Monitor donated by Andrea Pierdomenico.

I have received to repair five TI-99/4A with the following defects:

1. Black Screen
2. Working but with some dirt on the screen.
3. Vertical Stripes moving with a deafening sound.
4. Blue Screen with thin vertical stripes and deafening sound.
5. Blue Screen with thin vertical stripes and deafening sound.

The first two are repaired with the following faults:

Black Screen Fault: replaced TMS9929A followed by ROM CD2156NL
Dirt on the screen: replaced a 4116 RAM.

The third motherboard was used for spare parts.

The fourth and fifth motherboard with the blue screen have been the most annoying.

I spent 6 + hours to make measurements with an oscilloscope comparing one of the two motherboards with a working one to find the fault but the signals/voltages were absolutely identical.

So i have decided to go for exclusion and with a TI-99/4A Tech Data manual on my hand and 39.5 degrees in my Laboratory i have started to desolder and put a socket of the following components:

• 1 x TMS9901NL (20 +20 PIN)
• 1 x TMS9900NL (32 +32 PIN)
• 1 x TIM9904NL (10 +10 PIN)
• 1 x TMS 4732/2532 ROM U610 (12 +12 PIN)
• 1 x TMS 4732/2532 ROM U611 (12 +12 PIN)
• 1 x 74LS244 (10 +10 PIN)
• 1 x 74LS245 (10 +10 PIN)
• 1 x 74LS373 (10 +10 PIN)
• 1 x 74LS03 (7 +7 PIN)
• 1 x 74LS138 (8 +8 PIN)
• 1 x 74LS74 (7 +6 PIN)
• 1 x 4116 (8 +8 PIN)

After all this work nothing had changed, nothing worked, always BLUE screen.

I redid the measurements, but nothing, everything looked the same.

At this point there are only two static memories MCM6810P but that i don’t have investigated for what are used, because already on the motherboard are 8 x 4116 RAM Memory shared between Memory program and Video memory.

… anyway … i have tried to unsolder and put a socket.

So we add:

• 2 x MCM6810P (12 +12 PIN)

Et Voilà the two MCM6810P are both dead! both!

Obviously i don’t have this component in my laboratory, then i try to recover from the motherboard for spare these two RAM hoping that they are not faulty which however these RAM can be purchased online at a very low price.

The fifth and last motherboard that had the same defect of the previous one did not have the faulty ram MCM6810P.

To repair i had to replace the following components:

• 1 x 74LS04 (7 +7 PIN)
• 1 x TMS9900NL (32 +32 PIN)

from Wikipedia:

The Texas Instruments TI-99/4A was an early home computer, released in June 1981, originally at a price of US$525. It was an enhanced version of the less successful TI-99/4 model, which was released in late 1979 at a price of $1,150. The TI-99/4A added an additional graphics mode, “lowercase” characters consisting of small capitals, and a full travel keyboard. Its predecessor, the TI-99/4, featured a calculator-style chiclet keyboard and a character set that lacked lowercase text.

The TI-99/4A’s CPU, motherboard, and ROM cartridge (“Solid State Software”) slot were built into a single console, along with the keyboard. The power regulator board is housed below and in front of the cartridge slot under the sloped area to the right of the keyboard. This area gets very hot so users commonly refer to it as the “coffee cup warmer”. The external power supply, which was different according to the country of sale, was merely a step-down transformer.

Available peripherals included a 5¼” floppy disk drive and controller, an RS-232 card comprising two serial ports and one parallel port, a P-code card for Pascal support, a thermal printer, an acoustic coupler, a tape drive using standard audio cassettes as media, and a 32 KB memory expansion card. The TI-99/4 was sold with both the computer and a monitor (a modified 13″ Zenith Color TV) as Texas Instruments could not get their RF Modulator FCC approved in time. The TI-99/4A did ship with an RF Modulator.

In the early 1980s, TI was known as a pioneer in speech synthesis, and a highly popular plug-in speech synthesizer module was available for the TI-99/4 and 4A. Speech synthesizers were offered free with the purchase of a number of cartridges and were used by many TI-written video games (notable titles offered with speech during this promotion were Alpiner and Parsec). The synthesizer used a variant of linear predictive coding and had a small in-built vocabulary. The original intent was to release small cartridges that plugged directly into the synthesizer unit, which would increase the device’s built in vocabulary. However, the success of software text-to-speech in the Terminal Emulator II cartridge cancelled that plan. Most speech synthesizers were still shipped with the door that opened on the top, although very few had the connector inside. There are no known speech modules in existence for those few units with the connector. In many games (mostly those produced by TI), the speech synthesizer had relatively realistic voices. For example, Alpiner’s speech included male and female voices and could be quite sarcastic when the player made a bad move.
