... or another machine goes to Norway
I've decided that I'll finally start working on Atari ST machines that I've ordered some time ago. Most of the machines had broken cases or were severely yellowed but that is a story for another blog post.
Today, I have a short story about preparing an Atari for Alexander from Norway. He actually made me start working on STs ;)
Since Alexander ordered quite a few machines in the past I decided that I'll pick a best looking ST and arm it with few upgrades.
That was actually the only unit with a NOT cracked case
It had few scratches on a top cover but that was smoothened with a sandpaper later on.
Alexander asked me if I could install UK TOS in it. Obviously, that was not a problem. However, I didn't have UK keyboard. All 23 STs that I had, came with German TOS and keys so I've ended up buying a whole unit only to get a UK keyboard :D
In the meantime, I've started working on a GOTEK drive. I've flashed an awesome FlashFloppy firmware to it.
There was a small problem though ...
... unfortunately a ribbon cable was a bit too short ... grrrr ....
That finished Gotek mod. Below is a short video with Gotek running .
Video sync fix
In STFM series, there is a slight problem with video sync on modern TVs.
Atari simply loses sync after a reset which results in an unstable video output. There is a simple fix (Yay ! Internet FTW !). A resistor has to be soldered between chip pins near modulator.
I've soldered it on a bottom side of a PCB.
The final job was to put UK TOS 1.04 inside.
That was achieved by flashing and fitting two flashroms - Winbond W27C010.
These flash chips are not exactly pin-compatible - each of 'em has four more pins.
That is not a problem but requires running few external wires.
Below few pics of a finished work.
That's it. Job is done and new owner is very happy (AFAIK ;P)
ps. Atari also received a 4MB RAM upgrade but I forgot to take pics of that mod ;)
