Can a Q777 be removed from a Rev11 / 9.34 Series III?

Can a Q777 be removed from a Rev11 / 9.34 Series III?

2015-07-14 by chaworth01@googlemail.com

Hi all,

Not much activity on the forum these days, so hoping that a few are still hanging around!!

I'm going through a full service of my Series III at the moment and in the interests of log-term reliability and power consumption, I'm removing all cards and devices that are not necessay to it's day-to-day operation (such as the floppy contoller and drive).

With this in mind, does anyone know if it is possible to remove the Q777 card? To be honest, whilst I'm aware that for the earlier revisions it held the SCSI device firmware, I'm not sure what it's role is in a latter spec Series III, given that the CMI41 and TS-1 are handing SCSI activities. All I know is that the machine won't work without it!

Any advice would be welcome.

No you can’t just remove the Q777 – From memory there is some logic that is required to enable DMA operations to continue as normal.

At minimum If I remember correctly you need a Q007 to place in that slot instead. This was a card with may be 1 or 2 LS logic chips on it that completed the DMA chain.

There are a few references to the Q007 here … http://kmi9000.tripod.com/kmi_cmi_hard.htm

About group activity: I tried to sign up with a new account, but got no reply, so I think the group is not getting new members........

Power consumption: One person in AH (Analogue Heaven) group told that he didn't recommend buying a Fairlight or Synclavier, since they draw allot of power. When I planned buying a Synclavier and got info, it turned out that the system I'd like would draw 10A, that is 2300 Watts... The system the seller used even used 20A....
Now I don't know how much a series III uses, but for my IIx I measured just about 275 Watts, which is less than most modern desktops and is not so bad at all. How much does a series III draw?

Regards,

Peter Kersten.

From memory it only has one or two chips on it and a jumper.

Again from memory, the jumper selects which slot the card is plugged into, one position will be the hard disk controller, the other the floppy controller.

Thanks Steve. Appreciate your quick response.

I actually have a Q077 in my (small) spares collection and did wonder whether this was the replacement card I was looking for, so thanks for confirming.

Just out of curiosity: how much power consumption are we talking about? How much do you want to cut it down?
