is it available for purchase? I'm from Italy! Thanks!

[Best "everdrive" for Atari 800 XL]

Thanks to all for your very useful replies!

 

So, not having been a possessor of an Atari 8 Bit in the '80s, I ask you: did the best or the "iconic" games are released on cart, tape or disk?

 

Many thanks!

What is an everdrive?

 

Do you mean an SD card floppy emulator?

 

Not exactly, I mean a SD solution that works not only with ROM cartridges (I know there is the Ultimate Cart for this) but also with Floppy and Tapes images...

Hi!

 

As from topic, what is the best "everdrive" solution supporting not only cartridges images but also disks and tapes images?

[TI-99/4A doesn't power on, how to measure voltage]

The total voltage across the secondary of the transformer is the sum of the divided voltages.

 

...lee

Many thanks for the explanation and for your help!!

[TI-99/4A doesn't power on, how to measure voltage]

Here are the measures on the transformer... why that 27v?

 

[TI-99/4A doesn't power on, how to measure voltage]

If you measure the voltages at the red/black/white wires on the PSU PCB, you should get:

 

-- across white and black - about 9V AC

-- across white and red - about 19V AC

 

You can measure the DC output voltages on the white 4-pin connector. The voltage on each pin is written in yellow on the PCB. Measure between the GND pin (black probe) and each of the other pins in turn (red probe). Make sure the probes don't slip and short between two pins! Make sure you set your multimeter to DC Volts for these. The voltages may be around 0.2V higher than stated as there is no load on the PSU.

Ok, I get exactly these measures!

Ok, Ive changed the fuses and now the light on power supply works, here are the measures.

but it reads only 4

Ok, here its mine:

Hi all from Italy!

 

 

My TI-99/4A suddenly doesn't power up!

 

So I've disassembled the machine to isolate the internal power supply.

 

Now I have, as from the photos, the power supply and the external original transformer.

 

How can I test the voltage with my multimeter?

 

Where have I to insert the red probe and the ground probe to measure the voltage for the transformer and for the power supply?

 

You'll find all the photos attached...

 

 

Many thanks in advance!

[Atari 2600 sudden video -audio problem]

Ok, the problem was the TIA.

[Atari 2600 sudden video -audio problem]

Hi!

Yesterday I was in a retrogamer fair here in Italy with my Atari 2600 Light Sixer and suddenly I've got the video problems you can see in these two videos (same problem with whatever cartidge I've tried).

What can be the problem?

Thanks in advance!

[Atari 2600 horizontal interference bands]

Thanks! Can I order the kits for shipping to Italy? How?

[Atari 2600 horizontal interference bands]

Is this kit good, for example? https://console5.com/store/atari-2600-total-refresh-kit-new-capacitors.html

[Atari 2600 horizontal interference bands]

Thanks Mojoatomic!

 

So I have to replace: C243, C240, C241 and C214?

 

Can i find theme in a regular electronics store or there is some place to buy from?

 

Thanks again!

As in the video above, I have these horizontal interference bands in my Atari2600 I can't get rid of. The model is 2600AP Rev, I changed the RF Modulator with a new one, the coaxial is connected to the tv tuner of the Philips Cm8833 with a coaxial-male adaptor, you can see some pictures here below.

 

 

 

 

 

 

Thanks in advance!
