Hi Damir,

I’m using a SCSI2SDv5.1 which states it can run at 1.1 to 2.6MB/s.

The “SASI interface not ready” error is appearing, even when the SCSI2SD is disconnected from the 50 way IDC.

Glad to see you taking on the job of getting an sd card reader solution.

One company will even take your boot disk and load it on the sd ram for you.

If you can add an sd to a Fairlight series II it must be possible for us.

Thanks for being here. The 3.5 drives are not special either other than scsi with id set pins.

Yes, I'm motivated to get this working, though am not sure if I have an inherent issue with the SASI controller on the processor board.

If anyone else has a 4100A processor and could verify, by enabling the 20MB Cartridge option in the setup, then disconnecting the Bernoulli drive (or perhaps you don't even have one), if the "SASI interface not responding" error appears on start up.

I need to determine if the non-response error is due to the emulator not responding, or if there is a problem with my processor.

To verify the processor, I'm hoping to get a hold of a Bernoulli drive as well, just for testing.

Anthony.

Cruel Allen! Hehe! Someone has to do it!
Theres a lot of stuff on the web about SASI being very close to SCSI.
See this post
https://retrocomputing.stackexchange.com/questions/10900/was-the-ancestor-of-scsi-the-sasi-protocol-nothing-more-than-a-draft
Also, SCSI is generally very picky about termination, so make sure you have the bus terminated.

We'll at this point, I'm seeing absolutely no activity on my SCSI port on the processor board (using a data scanner), so either there is a problem on the board, with the cable, or with the emulator. It's not an ideal start.
I will not be defeated however...

Does anyone at all have any kind of documentation for the 4100 processor board?
Does it even exist, or was it kept private due to CA manufacturing the boards, and not SSL?

Anthony.

Trying to keep my mind off other things.....

Last week I've picked up 10 more E modules, and have 24 VU meters being shipped - should they ever arrive....

Had a problem with the computer where 6 hours in to a session, the VDU went on the fritz. It was quite hot in the control room having the console, computer, and 2" machine running. I had to shut the computer down after a few attempts of restarting did not fix it. In the morning it worked correctly and is back to normal.
The computer was running and responding to commands perfectly, just with garbage all over the screen. TR worked fine as well.

I'm assuming this is the MM2012AN Video Memory, on the Keyboard and VDU card? 8 chips of 1024 bytes each?
