amiga 1200 rear trap door

[shinto30]

Hya just a quickie from an old amigan who`s come back from the land of pc building.
what was the rear trap door in the amiga designed for?


at moment building my self a 1200 with internal cdrom + internal cf card reader great fun lol :lol:  :-x  :-P

The rear trap door covers the bay in which a SCSI connector can be installed. As far as I know, the only way to install a SCSI controller is as an add-on to an accelerator (in the expansion bay underneath the Amiga).

You could run a fast serial port out through there instead, if you want. I think there were some CD drives with a cable that went in through that space too.

[Hodgkinson]

Additional serial ports can go there too...I added a HyperCOM MK1 there as in this photo

EDIT: :crazy: meega beat me to it...It's too late at night for this kinda thing :-D

You could also use it to mount the VGA connector of the Blizzardvision PPC (an RTG graphics card add-on for the Blizzard PPC accelerator card), or the USB ports of the Subway USB controller (an add-on which attaches to the clockport)

@DrDekker

The Expansion Systems Dataflyer 1200 added SCSI (via the IDE port) and used the rear knock out panel.

 Putting all together:

 - SCSI controllers;
 - VGA out for a BVision or an internal scandoubler;
 - Fast serial and/or parallel ports;
 - USB connectors (from a Subway USB);

 And any other nice hack you can think to fit in the spot.

Oops - I'd completely forgotten about the Dataflyer!

Does the Dataflyer replace the IDE port with SCSI or does it retain the IDE port (add more ports perhaps?) and add SCSI?

AND some clockport sound cards

That's right, I remember the Melody 1200 had a cool plate that fitted four audio connectors in that space.

I've also seen PS/2 mouse adapters and external keyboard adapters fit into that space.  I think the two most common uses though are for external scsi port from a trapdoor accelerator or a DB25 fast serial port connector (hypercom, silversurfer, twister, etc.).

It allows the connection of an IDE harddrive to the standard internal IDE port and then on the same cable terminates with a small SCSI connector in the little flap. I sold a 1200 recently that had an external SCSI CDROM connected to that port as well as an internal IDE drive.

 The 1200 version of the Dataflyer adds 5 more devices to the internal IDE connector.

 It "reserve" the two first channels to the IDE and the 5 next channels are for SCSI "1" devices. I have a 4000 version attached to the internal IDE port and it works like a charm (little hack).

.... PS that's what the little hole in the bottom of the Amiga is for .. To screw the holding plate for the port in place. Tricky getting the ribbon through... You need an A level in Origami  :lol:
