Many thanks to my friend Ciro of TI-99 Italian User Club for this fantastic gift.

The EXL 100 was done by people who worked at Texas Instruments. It uses a lot of technologies of the TI CC40 (like the basic and the CPU for exemple).

ll the hardware is based on Texas Instruments chips. The TMS 7020 is the CPU, the TMS 7041 manages all I/O, the speech synthesizer (TMS 5220) and the infrared receiver. The keyboard and the joysticks are linked by infrared to the CPU.

Several peripherals were developped for this computer : a dot matrix printer (EXL 80) and a modem (ExelModem). This computer didn’t have a great market success. It was above all used in schools.

Irradio XTC-506R Repaired again.

It seems this small Irradio TV/Monitor always suffers from some problem, last time there were short circuits caused by the pressure of the cathode ray tube on the PCB.

This time some cold joints on the solder pads.it would have been very sad to throw it in the garbage trash.

Nintendo Virtual Boy Repair.

First of all, i thank Andrea Pierdomenico for this fantastic gift.

Below i explain how i have repaired the Nintendo Virtual Boy which show the classic display malfunction problems (both).

I have used only a pencil eraser and a SMD Rework Station to fix the connections of the ribbon cable to the Display PCB of the Virtual Boy.

The process involves heating the connection of ribbon cable to the Display and using a pencil eraser to push segments of the ribbon cable to the PCB.

I configured the hot air station to 145 Degrees and 55 of Air Pressure and i made 3 fast transition without ever stopping at a specific point, pressing between one pass and another with the pencil eraser.

It Works!

Thanks to my friends Charlie and Gerben for this fantastic gift which adds another piece to my Atari Collection that now begins to become respectable.

UAV (Ultimate Atari Video) Video Upgrade for Atari Computers & Consoles.

This circuit improves the signal video output and allow to use both output (SVIDEO and COMPOSITE). The circuit is compatible with all Atari 2600, 5200, 7800 consoles and all Atari Home Computers 400, 800, 1200 …

I thank my friend Charlie for giving me this circuit that i have immediately installed in my Atari 2600 Jr which i use with the Harmony SD Cartridge.

NOTE:

Don’t use the socket in place of the IC 4050 as seen in the photo. The external case of the Atari 2600Jr console is too thin and cannot be closed anymore.
