Versions of PCMCIA Card

PCMCIA Card was designed by the PCMCIA which is an acronym for Personal Computer Memory Card International Association. Owing to the difficulty expressed by people in pronouncing the acronym, it was dubbed "people can't memorize computer industry." For marketing reasons and easier pronunciation, the name PC card was used in place of PCMCIA Card. The right to use PC card was gotten from IBM. The version 2 of PCMCIA card became known as PC card.

This version of PCMCIA card is designed to be used for many functions in notebook personal computers, for modems and networks. Another version of PCMCIA card is known as CardBus. This is a 32-bit version of PC card standard. This version of PCMCIA card does not only support 32 bits which is a wider bus than the 16 bits, it is also designed to support the mastering of bus and the speeding up of 33 MHz.

The package of all PCMCIA card devices is similar and they are of same size with credit card. The length of the size is 85.6 mm while the width is 54.0mm. PCMCIA card are of different types. The type I is the initial standard which has a 16-bit interface. It has a thickness of 3.3mm. They can be used in such memory devices as RAM, OTP, flash memory and SRAM cards.

The type II can support 16-bit as well as 32 bit interface. They have a thickness of 5.0 mm. They are also designed to accommodate interfaces that are not built in the host computer. They can be used in such applications as TV cards and modem network. The type II of PCMCIA card is of different types. Each type has its own peculiarities.

Just like type II, the type III of PCMCIA card devices can support 16-bit and 32-bit also. Their thickness is 10.5 mm. Their thickness makes it possible for them to accommodate those components that cannot be accommodated by the earlier discussed types.

The last type of PC card devices was launched by Toshiba but it is yet to be sanctioned by the PCMCIA. The thickness of these PC card devices are 16 mm.

The later specification of PCMCIA Card is known as ExpressCard which is designed to replace PC Card. The thickness is 34mm and there is a PCMCIA adapter meant to help people used the ExpressCard.

Where can I find a 12v 1000mA power adapter for a ExpressCard 34 to FireWire IEEE 1394a Controller Card?

I have a video capture device (ADVC 55) that uses the 6 pin FireWire for both power and video processing. Unfortunately my Controller Card doesn't seem to have enough power to run this device as I was reading the manual and it mentions the use of a power adapter for certain devices that require bus power. These are the specifications for the power adapter for the controller card which I need, but cannot find.

Best Connectivity ExpressCard to Firewire IEEE 1394a Controller Card SD-EXP30012

*Input: AC 100~240V, 50/60HZ, 0.5A (500mA)
*Output: DC +12V, 1.0A (1000mA)
*DC plug polarity: Outside = Negative (-), Inside = Positive (+)
*DC plug contact dimension: Outer diameter 3.5mm, Inner diameter 1.3mm, Length 9.5mm.

That's what it says on the manual.

Radioshack will have exactly what you need. Take your item with you so they can match the plug to the jack, and the polarity.

You'll need an adapta-plug (they have the right one there) to go along with it.
