30Video for Macintosh SE/30 & IIsi

30Video is a series of video cards for Macintosh SE/30 & IIsi that I developed, released in July 2024. These cards are not a clone or reverse engineered board, they are a 100% new scratch hardware design I developed and wrote a ROM driver for.

The Macintosh SE/30 in its stock form has a B&W internal display, without the ability to display color or even shades of gray. However, the SE/30 is essentially a cut-down Macintosh IIx and the ROM contains Color QuickDraw to support color operation. So with the addition of an appropriate card the SE/30 can support a color display!

Essentials

All models have an external VGA connector and include the VGA mounting bracket.
Color depths: B&W, 4, 16, 256, Thousands (HC Card only)
VGA Resolutions: 640x480@60hz, 800x600@75hz, 1024x768@54hz ( *1 )
Plug and play, no drivers needed! Tested with Mac OS 6.0.8 - 8.1 and A/UX 3
Select slot IDs 9, A for use with other PDS cards.
Supports all known CPU accelerators and ROMs
Gamma support (CRT and LCD, defaults to LCD)
No quickdraw acceleration (same as other SE/30 cards)
Maximum power consumption of 2 watts combined +5V and +12V
Standard 30Video card (non-HC) has PDS Passthrough slot for stacking additional cards

*1 1024x768@54hz is a nonstandard resolution intended only for modern LCD monitors. Not all monitors will sync correctly with this, but most do.

SE/30 Grayscale kit: Upgrade internal CRT to display 256 shades of grey!

The Micron Xceed is a "legendary" video card which allows the SE/30 internal screen to display 256 shades of gray instead of the stock Black and White. Unfortunately, Xceed cards are extremely hard to come by, and very expensive when they do appear. I created the 30Video GS (and later HC) boards to allow more folks to play with Grayscale on their SE/30.

Demo!
1, 4, 16, and 256 shades of gray at the original 512x342 resolution.
Linear LCD Gamma and CRT Gamma are provided for each mode (Grayscale defaults to CRT; VGA defaults to LCD)
"Virtual" desktop scrolling 512x684 display mode provides more working room
Grayscale harness uses longer wires for stacking and 18 gauge +5v/+12v wires to reduce voltage drop.
Neckboard derivative of Bolle's design - Thanks Bolle!
Supports external video output: You can dual display (extended desktop) with an external VGA monitor in color while the internal display works in B&W.

SE/30 LCD Kits: Ditch the CRT!

I created these kits to replace the original CRT and analog board with a brand-new 8.4" 640x480 LCD panel. If grayscale isn't your thing or your original CRT/analog board is failing, give this a shot instead. Each kit includes all that is neccisary to perform the upgrade, including a 30Video HC PDS video card, new LCD panel assembly, "dummy" analog board, and all hardware/cables. Just transfer the fan from your old analog board and you're set!

Demo!
Fully digital 640x480 LCD for maximum crispness.
Uses a high quality TN panel with good viewing angles.
Adds thousands of colors support. *1
Supports mirroring Internal LCD with VGA output at 640x480.
Supports higher resolution video output over VGA. LCD disabled in the higher resolution modes, but will re-enable automatically if VGA is disconnected regardless of setting.
SE/30 onboard video will be disabled if LCD is connected: no "ghost" monitors.
900 nits LCD brightness, adjusted on the back of the LCD panel. *2
LCD Kit Installation guide

*1 Thousands of colors up to 800x600. Grayscale output is limited to 16 shades of grey due to Mac OS limitations.
*2 There are PCB footprints to fit an external brightness control potentiometer, but there is not one fitted due to lack of a suitable currently produced potentiometer. See here for some information on how to install one yourself.

FAQs

Can I run a vintage apple monitor off one of these cards?
- You might be able to adapt the VGA connector into something a vintage monitor will accept, but I can't guarentee they will work properly as VGA-standard video timings are used rather than Apple's video timings. YMMV.

Can the Grayscale/LCD Kit be used with a Macintosh SE, Plus, 512K?
- No. The 68000-based early macintoshes lack support for Color QuickDraw (among other issues) and as a result the approach I take with the SE/30 is not possible with these machines.

High Voltage Warning

Caution: It is necessary to handle high voltage components of your Macintosh while installing a Grayscale or LCD kit. Take appropriate precautions while working inside your machine!

I can not take responsibility if you accidentally injure yourself or cause damage to your computer during the installation process. If you are at all uncomfortable with the procedures to install these kits, please seek a qualified individual to perform the installation for you.

Stacking cards

You may stack an additional PDS card on top of 30Video cards with a passthrough slot. When installing a second card, carefully bend the chassis card support tabs away from the cards so they do not make contact with any card, and cover the tabs with insulating tape. 30Video supports slots ID 9 and A, selectable by slide switch on the card.

Please note: Most systems should be able to support two add-in cards, however, any additional cards are not guaranteed to work and can cause system instability / inability to boot as the system was originally designed for a single add-in card only.
