Cardbus or PCMCIA?

How to detect these?

Look at the attached picture. If you see the yellow strip of bumps, it is a 32bit cardbus card and you can immediately forget about hunting for Amiga drivers.

For what it's worth, neither of the cards in the picture are suitable for Amiga use, I just dug up the first PCMCIA and Cardbus cards I could find from my box of computer.

nice info Jope :great
did not knew about that...

Just a small note: PCMCIA cards are called PC-Card in the other world.

For a 16bit card, the single strip is thin, for a 32bit card, the right hand strip is thick. This should prevent you from plugging a 32bit card into a 16bit slot unless you use excess force.


There are exceptions.
The PCMCIA Multicard reader many of us bought, has a cardbus notch on the side but it's actually NOT a cardbus device. It does not have the strip of yellow bumps though so that IS a good measure :)

The gold strip is for signal noise on the higher speed cardbus (thereby identifying it as a cardbus card).

The keying on the sides of the card is for 3.3V vs 5V. Some pcmcia cards can only do either, some both (same goes for the slots). Don't know what voltage the Amiga slot is supposed to be able to handle - I suppose looking at the schematics might come up with the answer.

There are PCMCIA Type I/II/II cards with increasing thickness - the Amiga can handle up to the Type II cards?

the Amiga PCMCIA can support

16 bit PC-Card (type 2), 3.3v cards

PCMCIA PC-Card pins are all inline. Whereas the Toshiba and IBM RAM card slot has staggered pins.

ahhh the classic 5volt Toshiba Hybrid cards.

yes a I have a fair few here.....

Thanks didn't know that. I just bought a Merlin u530 16bit 3g card for use with my laptop. Would be cool if there was Amiga drivers for it :)

alexh 29 June 2008 16:16

There are no drivers for any 3G cards AFAIK. The only PCMCIA drivers I know of are:

10 Mbit Ethernet (NE2000 + 3C589)
802.11b 11Mbit Wireless Ethernet (Prism2)
Compact Flash
Serial/Modem
And of course Squirrel interfaces.

http://www.pcmcia.org/pccard.htm#lowv

It appears the amiga slot is keyed to accept 5V cards according to the above link, and that someone has to file off part of their 3.3V card to fit it in. However the card would have worked fine, as the amiga is indeed 3.3V!

The low voltage (3.3V) key on the card is thicker (2/3 thickness) than the 5V key (1/3 thickness).

It appears that the PCMCIA specification also allows another low voltage operation of X.X, but that must not have been used (much if at all).

As to cards (and slots) that are supposed to operate at both 5V and 3.3V, not sure what they should be keyed like. (I am guessing the card would be keyed like a 5V so it can fit in all slots, and the slot would be keyed like a 3.3V so it can take all cards, but you never know).

Here's another link showing the thinner edge of the 5V pcmcia card:

Also some (not so) proprietary Amiga IDE devices (C= Overdrive and Zappo, among others), one ISDN card, etc.

For a complete list, look at http://bboah.amiga-resistance.info/c...onnlist_en.cgi and choose PCMCIA (not counting NIC cards, SRAM cards and CF adaptors).
