exxos's Atari, Amiga & retro forum

Hello people!

I want to share with you the adventures with my first Atari home computer:

Recently purchased: No yellowing :D

It Works!
First stage, the TOS:
I have extracted the old TOS ic,s:
And I have flashed the last TOS version, 2.06
Booting and Working the 2.06 TOS: :mrgreen:
Second Stage, the UltraSatan:
:twisted:

It must continue...

@valfac Could you upload the images please , Instead of linking to external imaging sites is actually against the forum rules :)

Sorry :|

@valfac thanks for editing the post :thumbup:

Continue..

Next, after waiting few months, I have purchased from EXXOS Shop the STE booster v1 :twisted:

First thing is locate the 68K socket:
We must desolder it. I have used a desolder gun, overall it didn't cost me much but the ground pins were worse than a toothache.
For the ground pins I use a technique that consists of lifting the pin from the socket and heating the pin with the soldering iron until it is released.

Then a manual desoldering machine was the most effective.
Now is moment to solder the Booster v1:

Next.. I have soldered the cables:
And power on :D
And some days after, the dual TOS came from the exxos store (I forgot to buy the TOS IC)
I had a little technical problem and I had to stop the assembly temporarily. I had an electrical problem that was solved.

I want to thank the kindness of @exxos that helped me solve the problem sending me some small spare parts so that I could continue...

He also warned me that the STE RAM SIMM was no adecuate (simm with parity)
But it was solved quickly :D
To be continue...

:bravo: :goodpost:

Nice work!

Thanks!

Continue...

Shortly after, exxos manufactured new dual TOS plates, a little longer that avoided desoldering the original EPROM sockets, as I was lazy 8-) to desolder the sockets I bought a unit from the dual TOS kit:
Here you can compare the new and the old model:

Attach it is very simple:
Now we have the dual TOS version selectable with a jumper. I the future I wil put a switch.
To be continue...

More...

The last step, is to desolder from ground the cable that switches between the mode 8Mhz to 32mhz and test the news capabilities:
:twisted:
Before:
After:

I have to say that since I turning on the Atari computer the operation of the STE Booster v1 is very noticiable. The RAM test happens like a bullet. After the TOS start very easy and manage the windows of TOS is much more comfortable.

I have not done many more test but I am satisfied with the result.
:D

Now I'm waiting for a new PSU from Exxos,s Shop, but the PSU is another history to share with you.
