Do you have problems with clicks in your recordings or other general problems in Cubase Audio, try reading my guide about getting Cubase Audio to work as good as possible here.

If you want to modify your audio in/outputs to standard line levels, you should either look in your Cubase Audio users' manual or read the modified version here.

Do you have problems with Cubase Audio hanging/bombing or giving you a lot of annoying clicks in the audio files or maybe general problems on the SCSI-bus? Then you should make one of the clock patches - there are three of them: CLKMOD1.JPG, CLKMOD2.JPG and CLKMOD3.JPG. These pictures describe three different ways to make the necessary modifications. Unfortunately, there's no way of telling which one to make - it's trial and error starting with no.1 - but eventually you'll get it right.
All of the modifications include soldering on your PCB and it incorporates surface-mounted components. If you're not very familiar with soldering this kind of components, you shouldn't do it yourself, but rather leave the machine to someone who is very experienced with a soldering pen.

If you have problems booting up the machine, the NVRAM might have locked up some way - or you may accidentally have set the video mode to something that can't be displayed on your monitor. The solution for this is F030FREE, which should be run with an empty, unprotected disk in your drive (do it NOW, to avoid problems getting hold of a Falcon to create the disk with later...). An executable boot sector will be created on the disk and if you start the machine clean with this disk inserted, the NVRAM will be reset to the factory defaults and you're back in business. As a temporary solution, you might have luck trying to reset the NVRAM settings by pressing Alt+Ctrl+right Shift+Undo immediately after power-on or reset.

Other common problems will be added as I come across and solve them, but here are a few to start with:
Problems with the mouse: Bad solderings on the port or bad 74LS244 on keyboard PCB.
Problems with the keyboard: Clean the contact surfaces in the keyboard, exchange the keyboard CPU or exchange the 6850 chip closest to the keyboard connector. Also check the lines between the 6850 and the connector, as well as the power and ground lines to the connector.
Cubase says "No key - bye": Exchange the mini fuse close to the cartridge port, exchange the 68901 chip, or clean the contact surfaces of both the port and the cartridge.
Midi problems: Exchange the 6850 chip closest to the midi ports or exchange the opto coupler.
SCSI-problems: Exchange the SCSI-controller chip, fix bad solderings on the SCSI-port or on the terminators (check that the terminators are inserted the right way), bad solderings on capacitors and resistors close to the connector.
Cubase Audio won't boot, but doesn't give an error message (computer seems to be working perfectly with other programs): Fix bad solderings on the DSP or Combel, exchange the DSP or the Combel.
Floppy won't work all the time: Exchange floppy or exchange the PSU.
Computer won't start at all: Reset the NVRAM, exchange the PSU, bad solderings on the CPU, poor contact to the RAM-board, broken surface mounted resistors (very hard to find) or other yet unsolved causes...
Stripes or bars on the screen, computer works ok otherwise: The RAM-board is poorly grounded (very common on the Wing cards with 30-pin SIMMs) - solder a cable from one of the card's GND lines to a GND line on the computer's PCB. Poor contact to the RAM-board - lift the RAM-board and clean the contact surfaces as good as possible (it's hard to do it perfectly). May also be a bad soldering on the Videl, or a bad Videl chip...
Time and date is wrong after the machine has been switched off, even though you've tried to change it more than once: NVRAM is bad and must be exchanged. The IC is a standard component, "DALLAS DS1287", "ST MK48T87B-24", "MC146818A" or "MCCS146818BM" (they can replace each other), so there shouldn't be too much trouble finding it in an electronics shop.
