Post by: lorddef on April 23, 2003, 09:50:31 PM

;-) I suspect the seller is just guessing regarding AGA.  At any rate, the edge connector is not Zorro.  It MAY fit in the A2000's video slot, or not.

A quick look on amiga-hardware.com and  amiga.resource.cx returned no results :-?

I got just such a board... it's an "Advanced Grafik Adapter" there of the name AGA. It has nothing to do with AGA as we know it from A1200/4000. It connects to the GFX port on the A2000.

True. It appears to be a Microway AGA-2000 Flicker Fixer for the A2000's Video Slot. Narrowing it down further, the 2000E version of the card, labeled "AGA 1390 EXPORT":

Microway Flicker Fixer AGA 2000 (http://www.amiga-hardware.com/microway.html) I recall when advertisments for this product appeared, thinking that the AGA designation could cause confusion. Most Display-Enhanser cards for the A2000 (mimicing the A3000's Amber chip) only handle the upper 12 registers pertaining to a HAM6 display, thus will not display more than a 4096 colour (HAM) display.... e.g. NOT an Amiga AGA (HAM8 - 262,144 Colour) display mode, but a Scan-Doubled (&FF) OCS-EGS display.
