The Orchid Pro Designer IIs provided up to 32768 colours with the 1 MB video RAM version, and if the Sierra HiColor RAMDAC is installed, the maximum resolution at this colour depth is 1024 x 768.

These are one of those rare cards that will work in either an 8-bit or 16-bit ISA or EISA slot, with auto-detection to switch to 8 or 16-bit data transfer speeds.

 

Board Revisions

The Orchid Pro Designer II card came in a number of board revisions. The major board revision, i.e. 1 or 2, does not indicate whether it's a short board or long board (both '1' and '2' revisions were manufactured in both short and long form). It is more likely Orchid worked to cost-reduce the ProDesigner II in 1991 with the most obvious change to replace the up to six individual crystal oscillators with a single 45 MHz crystal and a couple of PAL chips which presumably work as clock dividers for the various video mode refresh rates.
All long boards had part number 830-0045-X.
All short boards has part number 830-0071-X.

ProDesigner II Rev. 1A: short board (1991)
ProDesigner II Rev. 1B: long board (1990)
ProDesigner II Rev. 1B4: short board (1991)
ProDesigner II Rev. 1C: long board (1990)
ProDesigner II Rev. 2B1: short board (1991)
ProDesigner II Rev. 2D1: long board (1990)
ProDesigner IIs Rev. 2P8: short board (1991)

I've also never seen a 'long board' ProDesigner IIs, so presumably the IIs variant came after the 1991 cost-reduction, and the 's' suffix probably stands for 'short'.

 

Competition

 

 

In the Media

"PROS: Fast AutoCAD performance
CONS: Expensive

The most outstanding feature of the Orchid ProDesigner II is speed—it tied for first place in the key AutoCAD tests. Other than that, the board has an average set of features and a fairly high $304 street price.

Like most boards in this roundup, the ProDesigner II offers flicker-free 72 Hz performance at all resolutions except 1024 by 768. That may limit your options, but on today's 14-inch multiscans, most people won't experiment beyond 800 by 600 anyway.

The board isn't quite plug and play, but unless a network board is present, you probably won't have to mess with the board's handful of jumpers. Driver installation involves issuing commands from the DOS prompt instead of simply choosing menu options.

Thanks to its speedy performance, AutoCAD users may want to consider this board seriously. In addition, by the time you read this, Orchid will be shipping a new version of the ProDesigner II (the IIs) that will list for $120 less and purportedly will offer the same speed, 70-Hz refresh at 1024 by 768, and a special upgrade that will support over 32,000 colors under Windows. These new features should make the Pro-Designer IIs one of the hottest Super VGA boards around."

Setting it Up

The Orchid Pro Designer IIs has four DIP switches accessible on the backplate. The first two are used to set the monitor's vertical refresh rate:

  Configuration 640 x 480 800x 600 1024 x 768
SW1/SW2 Off/Off (default) 60 Hz 60 Hz 60 Hz
SW1/SW2 On/Off 60 Hz 56 Hz 45 Hz (i)
SW1/SW2 Off/On 72 Hz 72 Hz 60 Hz
SW1/SW2 On/On 72 Hz 72 Hz 70 Hz

SW3 and SW4 are factory-set and there is no mention of them in the manual, though some other Orchid cards have them setup for the following:

  Configuration Meaning
SW3 (Shadow ROM) ON When video shadow ROM is enabled and the system won't boot.
  OFF (default) When there is no conflict.
SW4 (Speed Boost) ON Boosts the speed of text and graphics operations from 10% - 25% by setting the card to run with zero wait states on bus accesses.
  OFF (default) Standard speed.

 

The Orchid Pro Designer IIs has these jumpers:

  Configuration Meaning
JP1 1-2 IRQ9 enabled. Enables the use of IRQ2/9 to control the use of the Vertical Interrupt.
  2-3 (default) IRQ9 disabled.
JP2 1-2 Motherboard compatibility on - Enables the Fahrenheit 1280 to operate when installed in motherboards which use non-standard bus timing signals. Set this to 1-2 if the system does not boot.
  2-3 (default) Set to this if the sign-on message is scrambled at boot up or graphics modes are scrambled in the software you are using.
