Yes , that is the point ;-) .
perhaps your PSU is much more tired than mine ... :-/
mmhhh.

i.e. a jumper across pin 34 (RDY) and Pin 33 (GND) on the Floppy 34 pin header.
No delays at startup.
Anyone have any schematics of the motherboard to confirm the need for a pull down resistor?

My CF-Card (I checked it with a SANDISC 256MB CF-Card) was not recognized. Maybe it was too old.
I did not check it. but I think that the CF-IDE-Bridge can be used connected directly to the internal IDE-bus of the Ultra with CF-cards that are setup as FIXED DISC.
I read that all CF-Cards from Kingston & Transcend are switching automaticly from Removable Disc to Fixed Disc, if necessary.
SANDISC-cards can be switched from "Removable" to "Fixed" using a software-tool. Just check via search-engine.
One think that definetly works is, if you connect the CF-IDE-adapter to the SCSI-bus via a IDE-SCSI-Bridge-adapter.
I used an Acard AEC-7720U and could successfully access the CF-Card.
I could format it with EOS-FAT & with FAT16/FAT32.
I also could save & load files from the CF-card.
The following Bridge-adapters should work with any CF-IDE-adapter:
- Acard AEC-7720U (suitable for a 5.25"-drivebay)
- Acard ARS-2000U (the only 3.5"-version)
- Bridge adapter from Glyph
- I-O Data Device Inc. (offered on ebay by the user "finestcomputers" from Hungary for AMIGA-users to connect a CF-IDE-adapter to an AMIGA-SCSI-interface)
There is also a japanese guy with the ebay-username "artmix" who, from time to time, offers a CF-Card to SCSI-adapter in 2.5"-format under the name POWERMONSTER. Direct website: http://www.artmix.com (all in japanese).

So hot-swapping of CF Cards is not available on either the internal SCSI bus or the IDE bus? On the external SCSI can a device be powered down and back up while the sampler is still running without damage or corruption?
