[Hemiko]

Hello.

I want to set up my vintage 486 motherboard compaq proline 4 / 66 and tulip prolinea 4 (motherboard TC40) and both need external cache card for better perfomance. Have anybody this cache card (i want least 256kb) for selling? If yes, please, write me.

I added image where could be one of these cache cards, pins count is like in this image. I found this image only one on the internet. Maybe this is for other purposes, i don't know because i am not hold this card ever. If I am wrong please right here how it is in reality.
