Yeah, beller gives good advice... Wait to get the system before purchasing anything additional.  The A4000 can output a signal compatible with a standard VGA monitor with no additional hardware.  

The problem is, it can only do that in Workbench and compatible applications.  (Typically not games, nothing you have to autoboot into, etc...)  But, those screens can be displayed on a TV, if need be.

So, you'll have a way to test the system in the configuration it arrives, and then can decide from there if the purchase of a scan doubler is necessary for what you'd like to do with it.

Honestly, if you're planning on selling on the Toaster and installing 3.9...  You'd probably want to look into a Cybervision 64 (or CV3D with attached scan doubler option) or a Picasso IV card, instead of just the scan doubler...

I realized right away none of my vga monitors were going to work with this computer.


Sure they will... for workbench.  Not having the install disk for Workbench is a pain, though.  But, if you can use the Magnavox or a TV to manually copy all the Workbench files needed to your hard drive, you should be all set.

The files you need for using a VGA monitor on an A1200/A4000 are located on the.... Storage disk, I believe?  (Might be Dosdrivers or something, I forget the way they were broken up, it's been a LOT of years...)  Anyhow, you need the screenmode definitions to put into DEVS:Dosdrivers (for 3.0) the files you'd need would be a screenmode (like DblNTSC, DblPAL, or MultiScan Productivity) and the file VGAOnly.

A reboot later, and your Amiga is outputting a standard VGA frequency signal on the 23 pin port on the back.  ;-)  (Which then will be out of range for the Magnavox or TV.  lol - can't have everything...)
