Has anyone got the 640 x 480 9.5" grayscale active matrix?

There were only passive matrix screens stock on the 190 / active matrix colour screen from a 5300c

Ah. Once again, lowendmac lies.

Powerbook 5300

displays:
640 x 480 9.5" grayscale active matrix with 16 shades

640 x 480 10.4" color dual scan with 16-bit color

800 x 600 10.4" color active matrix with 16-bit color

I've been hunting for one of these %$!! apocryphal screens for years.

To preserve what's left of my sanity, I've scoured everymac.com and compiled:

The definitive list of Powerbook 190/5300 LCDs

Code:

|=================================================================|
| Model          | Size  Color     Matrix  Bits  Shades    Pixels |
|=================================================================|
| 190, 5300      |  9.5   gray    passive     4      16   640x480 |
| 190cs, 5300cs  | 10.4  color  dual-scan     8     256   640x480 |
| 5300c          | 10.4  color     active     8     256   640x480 |
| 5300ce         | 10.4  color     active    16   1,000s  800x600 |
|=================================================================|

Maximum VRAM in every case is listed as 1MB; no minimum is given.
A 1MB 16 bit video card can be added to support an external color monitor.

The 5300ce required more vram to run an 800x600 screen / only works if connected to the 5300ce's specific logic board. / a 190 would not run an 800x600 colour screen, though I admit that I have never actually tried the swap.

Now, I suppose I could check the above against Apple's technotes/devnotes ... xx(
