Does a combo scsi ethernet isa card exist? My 486 only has 3 slots so I am wondering how I might be able to free up a slot.

What does it have onboard that it only has three slots?

The motherboard has ide, floppy, sound card, modem, serial, parallel and vga built in.
There are only 3 slots in the machine which a 16 bit ISA.
In the slots are 3com etherlink III, CEE GPIB interface and a adapter SCSI card. I have scsi / ethernet card for my Sun systems but those are sbus and PCI respectively. If such a card existed for ISA that would free up a slot for further expansion.

Instead of beating your head against the wall why don't you use an IDE drive? Or is that just too simple? 
What do you want to add that doesn't fit now?

What does your case look like? Is there room for a right-angle bus expander?

Actually they PC uses a propitiatory 3 slot riser.
Using IDE only isn't really an option for a number reasons.
1) The BIOS only supports hard drives connected to the IDE port
2) There is only one IDE header supporting a max of two hard drives.
3) I use the SCSI card for attaching my SyJet drive and CD-ROM.
SCSI is also significantly faster that IDE

I wouldn't be too concerned about SCSI out-pacing IDE on a 486 unless your into video editing or something of that nature which is disk intensive. So, what's the name and model number of your motherboard?
Here some fodder for you: http://www.milosoftware.com/mike/scsi_ide.html

Putting a round peg into a square hole is always more problems than it's worth.
A 'real' 486 (or anything) would obviously solve all your problems. :smile: :smile: :smile:

Depends on what generation of IDE/ATA you're using. I doubt that the comparison holds very well with narrow SCSI-2 devices.

My only thought here, is at the sacrifice of some performance, you could remove the ethernet card and move to using something like a Xircom PE3 - a parallel port based device.

It's a NEC ready 433
My SyJet drive came with one of the shuttle parallel to SCSI adapters. These are SUPER slow compared to real SCSI, writing in image 480mb image take 1-2 days over parallel SCSI adapter verses about 15-20 minutes via SCSI.
I haven't considered parallel to ethernet, I'll look into this the maybe the performance hit would be as bad.
About the max I can download something right now is 14kbps atleast under NT, via DOS maybe faster. Primarily I plan to use as this as a DOS machine, just have NT installed to see if I can get a BIOS update.
