Fully functional usable service manual. Considering the age of the manual and device quality was better than expected
 ;
Thank you very much, I've been very happy to find this manual on "Owner Manual". It's a perfect copy and it has been really useful for my work!
;
It took about 24-hours after my payment before I was able to get to the download. Apparently, payment processing is not 100% automated. That is no big deal, just be aware of that going in.
After I got to it, it was in good shape, easy to read, etc. Not some cheap FAX copy looking thing.
Also, this site was the cheapest I found. Another Plus!
;
Good price, very legible manual, exactly what I needed -- but had to wait a day to actually get the download of the manual. Would have preferred to download it immediately after payment rather than waiting for someone to "process" my order. I was surprised that I had to wait that long.
;
As the only source for this manual it rather rank quite high since it is well scanned and perfectly readable.

How To Replace a Flat Package IC
Preparation 9.2.3. Procedure
Even if you do not have the special tools (for example, a spot heater) to remove the Flat IC, with some solder (large amount), a soldering iron and a cutter knife, you can easily remove the ICs that have more than 100 pins.
� PbF (: Pb free) Solder � Soldering Iron Tip Temperature of 700°F ± 20°F (370°C ± 10°C) Note: We recommend a 30 to 40 Watt soldering iron. An expert may be able to use a 60 to 80 Watt iron where someone with less experience could overheat and damage the PCB foil. � Flux Recommended Flux: Specific Gravity � 0.82. Type � RMA (lower residue, non-cleaning type) Note: See About Lead Free Solder (PbF: Pb free) (P.3).
1. Tack the flat pack IC to the PCB by temporarily soldering two diagonally opposite pins in the correct positions on the PCB.
9.2.2.
Removal Procedure
1. Put plenty of solder on the IC pins so that the pins can be completely covered. Note: If the IC pins are not soldered enough, you may give pressure to the P.C. board when cutting the pins with a cutter.
Be certain each pin is located over the correct pad on the PCB. 2. Apply flux to all of the pins on the IC.
2. Make a few cuts into the joint (between the IC and its pins) first and then cut off the pins thoroughly.
3. Being careful to not unsolder the tack points, slide the soldering iron along the tips of the pins while feeding enough solder to the tip so that it flows under the pins as they are heated.
3. While the solder melts, remove it together with the IC pins.
9.2.4.
Removing Solder From Between Pins
1. Add a small amount of solder to the bridged pins. 2. With a hot iron, use a sweeping motion along the flat part of the pin to draw the solder from between the adjacent pads.
When you attach a new IC to the board, remove all solder left on the land with some tools like a soldering wire. If some solder is left at the joint on the board, the new IC will not be attached properly.
