Yeah, everything was Narrow SCSI back when. The internal is completely different then what you have pictured. What you have is for a desktop.

The laptop internal SCSI is a 40pin connector and to find an adapter you either have to make it yourself, or fork out $100+ on ebay.There is also this topic regarding making an adapter.

The SCSI and Floppy port are different. The floppy port is a HDI-20 port and are not interchangeable.

The Max ram for the 270c I believe is 32MB using a 28MB card. The largest made was a 48MB card for the Duo 2300c.
