My Nordic Apple /// : Part ///

two_trees_s

These two ///’s are latest additions to my ///-herd. What made this super interesting was that
the other /// had different keyboard with not just symbols on it, but TEXT. I’ve never seen such.
Might be replacement for some program specifially or something?

If you have information about this, let me know. Thank you. Tack så mycket!

keyboard_closeup_2_s
Text in front of the keycap.

keyboard_closeup_1_s
As well in top. Some kind of special localization here.

Naturally i had to check them thru and repair when needed (repair the /// is that really needed?).

a3s1-58712_label_s

Unit #1, Serial A3S1-58712, Made in Ireland. 256k

This unit came with the different swedish keyboard with text on it. I’ve never seen this
anywhere before. it would be interesting to know more about this. This is not an any
early 12v model either. Just regular 5v, 256k model otherwise. This unit had the
Corvus HDD-interface card installed! Thank god, so i can access the Corvus HDD and
look into that as well.

blown_rifa_s

Naturally (heh) the powersupply blew up when i was testing it. Loud noise, smoke
and bad smell. This was expteced to happen. I know… i know, one should always
replace those safely capasitors beforehand….  but. Yeah. Lazyness.
Maybe i learn someday?

Repair log:
-Normal cleaning everywhere.
-Installed new feet.
-Powersupply, new safety capasitors replaced (0,22uF, 0,1uF).
-New keyboard light installed.
-Floppyemu works with adapter (.woz, .dsk)

-The internall disk III wont work: no spin. No even trying.
*Tested with disk II mechanism, no difference.
*Worked with floppyemu
*470uf 10V capasitor replaced to disk III analog board
*220uf 16V capasitor replaced
*10uf 25V capasotor replaced
*ALL IC’s swapped to analog board
= STILL DIDN’T WORK!

small_pcb_s

*Replaced the capasitors to the small pcb behind the disk /// (10uf, 35V) and the
pcb felt like it had something leaked on.. very sticky like Coca-Cola poured on it.
Cleaned, swapped the caps.

*Made new interface cable as well…

ready_and_working_s

…and it WORKS!

.. i think it was all-along the cable! Should have started with that LOL It looked
about perfect but after closer look there were some dent/hole on it. Well it doesn’t
matter, atleast the drive got good cleanup, speed adjustment and other mainantance
done 🙂

While i was at it – i installed the clock/calendar chip and battery holder to it as well
the great custom ROM by Robert Justice that works nicely with the Booti-card allowing
direct USB/HDD boot from diskimage. Amazing. If something good happened in 2020 this is it!

 

 a3s1-56600_serial_label_s

Unit #2 – Serial: A3S1-56600, Made in Ireland, 256k

This one was much easier – no much issues…

Normal cleaning, disk drive working fine (adjusted), swapped an universal power
supply to this unit from an another unit for testing and swapped the safety capasitors
to the original one.

341-0060a-g9_s

Both of these had :

-341-0060A (2kb*8) that is Video scan decode ROM at 50HZ

euro_a3_crystal_s

-1970002 NDK 14.25045 Crystal 50HZ (PAL)

I only get black/white even with the RGB cable…
