Fortune 1 MPU Boards...(NOTE...Fortune 1 bds. components are indicated on a X-Y axsis (Alphabet on the vertical & numerical on the horizontal...so, if you can read a roadmap you can probably find the components I'm referring to).

See if this works...Fortune I wiring diagram...

Looks like it worked...here comes the rest...Fortune I MPU schematics...

Here's the schematics for the Fortune I Interface Board...

Sorry, about the quality of the Fortune I schematics, as you can probably tell these were copies of copies and had been used (abused) for years...hopefully they will be of use to someone out there.

Mike,

On the fortune 1 board do you need chips in socket cgo-b and cg1-b

Hi Ben

It's been the mid-90s since I worked on any of those boards, and I have tendency to forget knowledge I seldom use...I believe the sockets were filled, it may have been with jumper packs and not ICs...as I remember there were two jumper packs installed in sockets, I just don't remember the board designation!

Sorry, I'm not of more help, maybe you can get one of the dealers to take a picture of a Fortune 1 board and tell from that.

Good luck,

Anyone direct me to the 5v regulator on the board.  My machine just has a pure Blue screen.  This check list just states to replace 5v regulator.  Great, where is she at?

Hi "TECH" CHAD,

You might try looking for a three legged device (looks kind of like a low power MOSFET) that has 7805 stamped on it...

Good luck & God bless,
Mike><>

Just checked the schematic...evidently these boards were manufactured before the 7805 was around...the schematic has the 5V regulator being a, LM340T-5...you may have a tough time finding something from that era...

There are two 5 volt regulators. the one you are looking for I believe is in the right rear corner of the board ( G 16) inside what looks like a fence (heat sink). There are two there one is a 5 volt the other a 12 volt. If that's not it then there is another just to the left (E 14)next to the bridge rectifier, it may have a clip on heat sink. The board is laid out in a grid system with numbers running from left to right and letters running from front to back.

Hope this helps,
Big T

The standalone 5V regulator is a -5V regulator (negative 5 volts). The +5V regulator is inside the large heatsink along with the +12V regulator.

SAT, mucho thanks on the schematic posting. I have been busily redrawing them.

For your pleasure and usage, here is the interface board schematic redrawn.

and just grab the 6 pdf files. For the processor boardf, I will have them linked into a single pdf...
