Converting PCMCIA types

Zetr0 · 20 February 2007, 20:11

heys there

I am currently wondering if it is possible to convert between types of PCMCIA cards... specificially DRAM and SRAM cards...

recently I have scored a few cards PCMCIA from here and there, I was hoping that atleast one might be compatible with the PCMCIA port of the A600. alas the pins donot line up.

I have a 2MB sram card that has 68pin neatly 2 rows of 34 and works okay with the a600, I want to increase the amount of ram to atleast 4mb for testing purposes..

I have 4 other cards ( 2rows of 34 staggerd! )

4MB low power DRAM ( Kelly Micro Systems )
8MB low power DRAM ( new media corporation )
8MB low power DRAM ( STT4600/8 Toshiba )
32MB DRAM ( Smart Modular Technologies ) -PF125465-10

Code:

I have no qualms in building a bridge board... i am just wondering if its not only possible but if some one has done it before.

alexh · 20 February 2007, 22:50

two rows of staggered pins are NOT PCMCIA they are this strange hybrid design I am sure. Used on some laptops before PCMCIA became common. It is difficult to get the vendors to admit that they are not PCMCIA.

I would appreciate photo's of the cards that dont work so we can put together some sort of list.

Zetr0 · 20 February 2007, 22:55

if only i could find the pinouts of these hybrids, you never know alexh... a bridge board could be made...

although i doubt it would just be a passive solution it would be an interesting exercise me thinks...

when i get some time i will take some pictures

Smiley · 20 February 2007, 23:13

I thought the pcmcia slot could only handle 4mb of memory regardless of its type.

Interesting if you got something working. 32mb via pcmcia slot hmmmm

Zetr0 · 21 February 2007, 00:18

I doubt that could happen my friend, I dont believe the addressing space on the A6/12 pcmcia port can go that high... i think maximum is 8MB ... or was it 16... hmmm i have to hit the hayens manual

but still any would be nice...

alexh · 21 February 2007, 09:26

The maximum address space without paging is 4Mbytes

Zetr0 · 21 February 2007, 12:47

there ya go... 4MB!

thankies alexh!

I knew it!

I think you guys ought to channel your efforts towards a clip-onto-cpu 8MB expansion and forget the slow sram cards.. :-)

I will shot mine which isnt pcmcia but have same size, just as warning...

Waste of time if you ask me.

What is? The clipon mem expansion? Come now, that's a fun little soldering project.. Definitely more fun than PCMCIA RAM cards. :-)

Zetr0 · 21 February 2007, 22:26

@jope
now there something to have a little fun with in the summer hols!

@alexh
if only i could get my mits on the toshiba hybrid pcmcia pinouts!!!!

Zetr0 · 23 February 2007, 02:16

hmmmm

I dont seem to be having much luck finding a toshiba reference to thier *hybrid pcmcia design...

anyone got any ideas?
