ESCC Replacement
TorZidan:
I want to "connect the dots", even though the name of this thread has nothing to do with this :)
The "wireless connection through blue SCSI" that bmwcyclist currently uses to get on the internet is basically some software on the BlueSCSI card that emulates a DynaPort SCSI Ethernet adapter (along with emulating a SCSI hard drive): https://bluescsi.com/docs/WiFi-DaynaPORT
AFAIK, this is the easiest way to get old MACs and Lisa-s on the internets (along with PiSCSI, which is very similar to BlueSCSI).
The original DynaPort SCSI Ethernet adapter came in few different configurations: some had a BNC connector to connect to a 10Base2 local ethernet network (and from there to the internet), others had an RJ45 jack for the same.

I disagree. The BlueSCSI card's SCSI Ethernet emulation is handicapped by it's WiFi connection. Here is why:
Appletalk over Ethernet uses a different Ethernet frame type than common modern TCP/IP over Ethernet does. Most WiFi routers don't pass this frame type, so unless you have the right router, Appletalk data goes nowhere.
Using MacTCP you can directly connect to a TCP/IP network, but many MacTCP compatible applications require System 6.08 or better and that requires you run MW+II. For MW+II you will likely need more RAM and possibly an XLerator.

Interesting!
I hope to be playing with a number of these options soon.
I just purchased a SCSI-Ethernet (Asanti) adapter off of ebay, I have 2 BlueSCSI v2 units with wifi and I am also awaiting a serial to localtalk cable (vintage Lisa) from ebay, as well as 2 Raspberry Pi v4's to run as "routers".
(I was trying to hold out for some Gatorboxes but none have shown up for sale, I would love to see if I can setup a site to site link/tunnel with them)
One thing I have found as frustrating, and this is not limited to old Mac stuff, is that the terms bridge, router, and gateway (as in protocol translation, not as in 'default gateway'/'default router', which is a legacy term for gateway) are so often misused. I always need to locate the documentation and hope it clarifies which OSI layer the device operates on. Don't mind me, though, I still get agitated when someone says 'cable modem' and I have to bite my tongue to keep from asking "exactly where is the modulation-demodulation happening?

Rick, are you saying that there is an easier way (than using a BlueSCSI) to get a vintage Mac or a Lisa on the Internet? Please give us more details : what is the extra hardware and software needed?

I don't intend to answer for Rick.
I do want to clarify a few things.
I think there is a difference between "getting on the internet" and doing some of the more useful things on the internet. Using my Lisa under MW and 2 megabytes of RAM, about all I can do is use terminal software and ping. Using my XLerator card and 4 megs of RAM, I can (just barely) use an early browser (Mac Web) and some remote access software.
So far, I have achieved all of this with a BlueSCSI through an XLerator or Sun SCSI card.
I hope to now start trying to encapsulate AppleTalk through IP networks and connect to a remote Mac at my friend's house to play RoboSport.
