From.. Gerry Emson, c/o., The Tea Room, Venetian Marina Village, Cholmondeston, Nantwich, Cheshire. CW5 6DD. H E L P ! ! ! I have just bought a disc drive, to use with my back-up BBC, and would like some learned person to write direct to me at the above a ddress, and tell me how to wire it up!!!!. The following is all the information I can glean from the said piece of hardware..... Name on front.... EXCELERATOR PLUS. It is a five and quarter drive. I was told that it was Double sided, but I can't confirm this (unless you know how before I plug it in) There is an ON/OFF switch at the rear panel, along side this there are three DIN sockets. Two of these have 6 (six) pin holes, and the other has 5 (five) pin holes. There is also a small square hole underneath which allows operation of a red two pole dip swit ch... both are at present in the "ON" position. The person who sold it said it worked with a COMMODORE power supply unit, (output label states.....9v 1a and 5v 1.5a, although the din plug on the output side did not fit any of the din sockets. Having taken off the DIN plug, and checked the voltages at the wires they are as follows....brown (neg) and yellow (pos) 5v (on A.C. scale).....g reen(neg) and white(pos) 10.5v (on A.C. scale) The first object is to get power to the disc drive so question one..... which wire to which pins on which DIN PLUG/Socket. I assume this would be the 5 pin socket, but internal examination does not give any indication as to which. The second, (assuming the drive works), would it not be possible to power the drive from the BEEB direct, thus saving a p.s.u. If so , How do i wire this up, (both ends... )??? Third .... Now to get the Beeb to talk to the drive..... what wiring do I need to do this? If anyone out there can help me I would be very grateful to receive a written reply with wiring diagrams, direct. If there is any o ne within a 20 mile radius of Nantwich who I could visit with the gear for personal consultation, then a short note with telephone n umber would be very useful! In advance, Thank-you. Gerry Emson. HOPEFULLY SOME OTHER MEMBERS HAVE SOME EXPERIENCE WITH COMMODORE DISC DRIVES. I DON'T AS SUCH BUT WHAT I DO KNOW ABOUT COMMODORE WAS THAT IS COMMON WITH A NUMBER OF OTHER MANUFACTURERS THEY MADE GREAT EFFORTS TO MAKE THEIR STUFF AS EXCLUSIVE AS POSSABLE, FOR INSTANCE THEIR TAPE DECKS WHICH I DO HAVE SOME EXPERIENCE OF. GREAT PLAY WAS MADE OF THE FACT THAT YOU COULD ONLY USE A COMMODORE TAPE DECK AS OTHERS WON'T WORK AND MIGHT DAMAGE THE MACHINE. IN FACT THE ONLY REAL DIFFERENCE BETWEEN THEIR TAPE DECKS AND ANY OTHERS WAS THAT THEIR'S HAD A MICRO SWITCH UNDER THE PLAY BUTTON WHICH WAS ACTIVATED WHEN THE PLAY BUTTON WAS PRESSED SENDING A 5V SIGNAL ALONG A SEPARATE LINE TO THE COMPUTER. THIS SIGNAL WAS TERMINATED WHEN THE PLAY BUTTON WAS RELEASED AND THE COMPUTER WOULDN'T WORK UNLESS THIS SIGNAL WAS RIGHT. THE SOLUTION WAS TO MAKE A SEPARATE SWITCH AND USING A 5V SIGNAL FROM THE COMPUTER RELAY IT BACK AT THE SAME TIME AS THE PLAY BUTTON WAS PRESSED TURNING IT OFF AT THE SAME TIME AS THE PLAY BUTTON. NOW THIS DOESN'T REALLY ANSWER YOUR QUESTION ABOUT THE DISC DRIVE BUT DOES INDICATE WHAT YOU ARE UP AGAINST. IT SOUNDS AS IF COMMODORE HAVE PRODUCED SOME SORT OF SERIAL TYPE OF DISC DRIVE. MOST DRIVES WORK IN PARRALLEL, THAT IS THERE ARE 8 DATA LINES EACH SIMULTAINOUSLY SENDING THEIR OWN SIGNALS IN BINARY. SERIAL MEANS THAT THERE WILL ONLY BE ONE DATA LINE, THE OTHER LINES ARE FOR THE CONTROL OF THE DISC WHICH NEEDS TO BE DONE AND IS A LITTLE COMPLICATED. TRY OPENING THE DRIVE UP AND SEE IF THERE IS A SEPARATE BOARD CONNECTED TO A CONVENTIONAL DISC DRIVE SOCKET ON THE BACK OF THE DRIVE. I HATE TO SAY THIS BUT YOU MAY HAVE TO TAKE A LOSS ON THIS ONE. 5.25" DRIVES SUITABLE FOR 8 BIT ACORNS ARE QUITE DIFFICULT TO FIND NOW, THERE ARE A LOT OF OLD DRIVES FROM PC's BUT THESE AREN'T REALLY WORTH USING AS THEY WILL ONLY WORK IN 40 TRACK AND NOT ACORN 40 TRACK EITHER. IF YOU REALLY WANT A SECOND DRIVE LOOK FOR ONE OF THE 3.5" DRIVES WHICH ARE SOLD FOR PC's. I RECENTLY BOUGHT A HIGH DENSITY ONE FOR `29 AND IT WORKS BEAUTIFULLY. IF FACT ALL OF THE 3.5" EUG22's WERE PRODUCED ON IT. MAYBE I SHOULDN'T HAVE SAID THAT, I HAVEN'T HAD ANY RETURNS OF EUG22 AND I SHOULDN'T REALLY TEMPT FATE.
