Title: Bridgeboard questions
Post by: leofoe on July 10, 2005, 07:55:52 AM

I have an A2000 with an A2088 bridgeboard including a 5 1/4" floppy drive.
I managed it to work but I cannot read any drive. The drive light on the 5 1/4 floppy is always on. Is that correct? An external 3 1/2" disk drive connected to the external connector on the bridgeboard fails also. The light on that drive lights as if it were looking for the OS.
Besides that it is extremely slow. Keystrokes come 5 to 10 seconds later. Is that normal?

Hi,
Often, when the drive light is always on from the start, you've reversed the cable between drive and motherboard.

check this first !

Sorry, I saw your posting just now. I have the original floppy cable. The 5,25 inch drive seems to work, but since I've got no MS-DOS on those floppies I can't use it. I tried an Amiga floppy on the external connector. It does not work. It also does not work disconnecting the internal floppy and an Amiga drive at the external BB connector.
I have no old PC XT 3,5 inch floppy drive. I guess that's the one you need.
The cable has at the floppy side an ISA-like (but smaller) connector. If you still need it I can take a picture of the cable. Let me know.

The answer...

So you have to boot from the 5,25 drive at least once to setup a hd-file.

This is a clever idea:

Use PCTask to create a bootable hd that can be used by the BB!

I've got it up and running. But I decided to remove the bridgeboard because:
1. The A2088 is slower than PCTask.
2. You cannot use the internal drives. With PCTask you can.
3. I have no floppies for the internal 5,25" A-drive to work with.
3. An external drive attached to the BB does not work. However it should act as the B-drive.

[edit]
Of course this may not be true for other BB's.

4. i dont want any external drive :)

Can anybody post the picture (wiring) of that cable?

I have std. PC-Floppy cables but i dont know if must be crossed or not.

[edit] As you can see: no crossing of wires.
