Does anyone know if the 610 nubus adapter works in a 605.

I've found some sites that say yes and some that only mention the 610 for the adapter.

The link that says it will work is at

http://www.sunrem.com/database/quadra605.html

I was thinking about putting a nubus card in the 605.
If that doesn't work I'll have to put it in my mac IIcx.

No not yet.

I'm just wondering about the best way to do when I get one.

I might do it on my IIcx or get a nubus quadra.

I've got a lc580 lc575 and the 605 all without a nubus slot in sight.

On the IIcx I've only got the crappy mono video and I want to try and use it with my svga but can't test it at the moment cause I need to find some memory for it.

Q610 NuBus adapters won't work, because of the differing slot design. IIsi ones do though, and are very cool, as it opens up all the possibilities of NuBus, plus some come with ethernet ports, letting you get the most out of your PDS. However, to do this you will need to either leave the case off the LC, or build a custom case for it. This trick works with any LC from the original to the 475.

the UltraDock has a TON of room in it, maybe i should try to get one of those. i think that might have been the dock that was intended for the PC Card reader that never shipped.

ok, now i'm excited about this! any links to IIsi Nubus adapters on other machines would be greatly appreciated.

p.s. just did a doubletake, the IIsi adapter will work in the '020 PDS in the LC!?!

Probably not, IMHO. The PDS in the IIsi is the same size as the extended PDS in the LC III and later (its the 32bit, not the crippled 16bit of the LC and LC II)....

Well I've compared the pds pinouts of the IIsi and 605 and nothing matches up.

The IIsi's PDS pins are designed to match the 030 signals and the 605's are designed to match the 040 signals.

However it might work in some sort of offbeat way.

I hope someone can verify that it works.

If it works it's just pure luck.

It's no wonder hardly anyones heard of it before.

So the IIsi and 605 have 120 pin PDS slots and the PDS slot on the 605 is basically a 030 slot (like the IIsi) not a 040 slot.

The fpu on the IIsi adapter won't work because some address lines from the PDS slot get mapped to the primetime chip and this chip blocks the fpu acknowledge signals for the 605.

This primetime chip on the 605 emulates a few of the 030 cpu signals that the 040 doesn't have.

But the Ethernet on the adapter should work.

thanks for the links to those apple docs, do you have any to info on the systems that are successfully running NuBus on the LC PDS? i'm dying to see something. i also realized that the 2300c's ASIC might be a more functional revision, i wonder if the 280 ASIC blocks the FPU acknowledge signals. does it look like there should be a way to patch the logic board on the 605 to allow FPU access? it might have to be jumpered from mobo to adapter card if the signal path is severed at the EuroDin connector pin level, but a piece of wirewrap between boards ought to work. if several signals are lost a header/cable assembly might be brutal, but not entirely inelegant means of restoring functions apple swept aside. getting the IIe card to run on a 630 would be quite nice, but the NuBus adapter and a 24 bit 2 page video card would really be something.

I don't know of any people who are successfully using a setup such as this. However, i'm going to be a brave person and try it when i can get my hands on one of these things. I'd say though that the reason you wouldn't be able to use the FPU wiht the '040 is because the 68882 is designed to work in conjunction with a 68030, and nothing else.

Theres basically 3 types of PDS slots: PDS, SE-PDS, LC-PDS.
All three are NOT compatible with each other.
PDS: SE/30, II series (IIsi, IIvx, etc)
SE PDS: plain SE
LC PDS: Color Classic, LC series (LC, LC II, LC520.....)

I still think it's odd that the IIsi Nubus adapter will work in both a PDS and LC PDS slot seeing that they are'nt compatible with each other.

Does a IIsi SE/30 PDS ethernet card work in a LC PDS slot.
From what I've seen only a LC PDS ethernet card will work in a LC PDS slot.

There is something called pseudo slots used by the slot manager and it's in the IIsi and LC.

The PDS card gets mapped to a Nubus Address and gets treated like it's a Nubus Card ( ie a device driver for a PDS slot can be a Nubus device driver) and there is also ROM firmware in the IIsi to manage Nubus slots.

So I would say the ROM firmware is also in the LC models as well (but is not used except for the psuedo slots Nubus device drivers) and there must be some communication with the Nubus adapter chip because the PDS slot pinouts are physically different on the IIsi and LC models and the Nubus adapter pinouts would have to be mapped to the different (IIsi LC) PDS pinouts.

So if all that happens I would say the IIsi Nubus adapter would work with the LC models.

Seems like some of this stuff is undocumented or not well known.

Also the 610 PDS is 040 PDS whereas the 605 PDS is LC PDS and the IIsi is O30 PDS.

The IIsi 030 PDS id different from the LC PDS even though they are both based on 68030 PDS.

The PDS slot in a LC uses the memory address space occupied by a Nubus card in slot space $E.

Also on the PDS there is an interrupt line /SLOTIRQ.E which is the equivalent of the Nubus slot E interrupt.

Looks like the firmware in the LC's rom communicates with the PDS Nubus Adapter declaration rom and all the signal mapping from PDS to Nubus is set up allowing the PDS Nubus adapter to function as a Nubus slot.

This is the same for the IIsi.

The LC ROM firmware (for the Nubus Adapter) was probably included by Apple in case they offered a Nubus Adapter for the LC.

They probably didn't offer the LC Nubus Adapter because they might not have wanted to eat into the MacII sales.

I'm going to try my 605 with a IIsi Nubus Adapter when I get one.

Does the IIsi nubus adapter work in the SE/30's PDS slot.

The SE/30 and IIsi have similar PDS slots.

The pinouts of both PDS slots appear to be about the same.

Fitting the Nubus card and the adapter would be a bit of a challenge in the SE/30 if it would work.

Are there any nubus ethernet cards for the SE/30 that use the IIsi nubus adapter.

I saw on a website someone with a SE/30 and I think an asante PDS ethernet card.

The PDS asante ethernet card had a nubus out slot for a nubus card.

So that is one way to use nubus on the SE/30.

I recently placed an LCII and a IIsi alongside each other and took the lids off both.

Unfortunately, the LC PDS is indeed smaller than the '030 PDS. What this means is that the IIsi NuBus adapter WILL NOT FIT, nor will it work.

Sorry to give you the bad news.
