IIe card + ethernet in CC/LC at the same time...possible?

[elSchus]

Is it possible (through the use of some type of adapter or card combo) to have both the LC PDS IIe card installed and be able to use ethernet? I'm not talking about giving the IIe environment access to ethernet; rather, can you have both cards installed for the convenience of using either without pulling the logic board and doing a swap?

Check out the DevNote for how many PseudoSlot Addresses are available in the Memory Map. The LCII must have had more than one.


If there's more than one available in the LC's memory map: check out this thread for hints on adding another card to the top of one card or underneath the MoBo. I haven't gotten to the "Machine Pin" hack details as yet, but you'll get the gist of it.

Problems:

LC cards aren't likely to have provision for adjustable Pseudo Slot IDs.

Possible Solution:

Hack the card(s) and A/B switch the power legs of the DeclarationROMs on the cards for one at a time use.

Dunno, nice food for thought though!

Yeah, I've been wishing for a chassis for a multi-LCPDS card selector. Just something passive that I could switch the "active" card while the machine is powered off rather than needing to open up the case and physically swap cards. Kind of like the C64 mult-cart selectors but for LCPDS.

This really ought to be a simple hack.
How high is your EtherNet card after desoldering the RJ-45?
How high (tallest component from PCB surface) is the Apple II Card?

bbraun, have you looked at PseudoSlot ID availability on the LC/CC MemMap?

[bbraun]

I have not. For my purposes, I don't need (or even want) multiple cards on the bus simultaneously, just a passive switch to select which card is available rather than needing to tear the whole thing apart to switch cards. But it's just a wish list type of thing that I'll never get around to doing.

[Trash80toHP_Mini]

It's pretty much the same hack either way, one way's got the switch and the other doesn't need one.

Agreed: if the cards have two different pseudo-slot IDs, the switch is entirely redundant. You can have your cake and eat it too

If you have an LC, you could jury rig the ethernet card into the open floppy drive slot without much hacking, then run a ribbon cable to the switch/nubus connector.

Otherwise, you could look into a SCSI to Ethernet adapter, or, if you don't mind slower speed, an AppleTalk to Ethernet bridge.
