Identify IC an other parts on the Rambit Turbo Tape PCB

Recommended Posts

Hello,

 

In an effort to create a schematic of Rabmit Turbo Tape board, I would like to ask if someone can help to identify Integrated Circuit located on the RAMBIT TURBO TAPE Board.

 

1. The resistance values are obivous from the color codes

2. The IC is uknown. I would suspect 74LS03, but can anyone confirm or deny that, please?

3. What is the capacity of the capacitors?

 

Thank you for your help!

To explain, why I cannot identify the parts mysfelf - I do not have a RAMBIT TURBO TAPE board at hand. This photo comes from ftp.pigwa.net

Therefore my hope is someone has the board and will be kind enough to identify.

Hi Baktra, nice to see you here and at Atari Sector ;)

 

I am no technical expert (just a collector) but I made a picture of mine. You can read all the markings from the picture. If you want to see more, just ask ;)

 

Also attached is the manual of the Rambit upgrade.

 

Regards!

Fred

Wow. Thank you very much, Fred_M.

 

CD40106BE - Still sold CMOS flip-flop

BC182 - Still sold transistor - NPN.

S02A I04K - I don't know what that could be. Anyone knows?

 

If it is not much trouble, can you photograph the spots (from reasonable distance) where wires from the RTT board are connected to the datarecorder's main PCB?

Baker will be very happy.

Hi Baktra,

 

Yes I can make some shots, but in the attached manual there are 3 schematics for the two different 1010 models and the XC12. I scanned the manual and the schematics myself. This is not a copy of the manual you found online ;-)

 

The "s" in S02A I04k looks like some kind of trademark. It is a round dot with a "s" in it.

 

I will make some extra pictures and post them here in an hour or so ;-)

Okay, more pictures ;-)

 

First picture: my 1010 Hong Kong model. According to the manual and schematics another capacitor must be added to the PCB of the 1010.

 

Second picture: the added capacitor

 

Third picture: the "S02A I04k" part.

 

Good luck! and see you at the Sector ;-)

This is perfect!

Heh, I thought it states I04K, and it was 104K.

I thought so too ;-) Because the "1" looked as a different font I assumed it was an "I" and not a "1" ;-)

 

Luckily a picture helps ;-)
