The question isn't whether you can speak RS485, but rather SDLC.

That seems entirely reasonable to me.

Diagnostic mode There's also a way to enter diagnostic mode via SCSI, I just haven't gotten to looking at that yet.

The ROM kinda has that already builtin with the diagnostic mode. Grounding the VIA1 pin should work on the SE/30 too.

I'm interested in this, but I've got a couple other projects to work through first. The PS2 to pre-ADB & ADB adapter PCBs are supposed to arrive today, and after that I've been thinking of reviving the 030 PDS project. This is on the list, just hasn't been gotten to yet. If someone else...

It is all documented in the two books I mentioned, and probably numerous places elsewhere. There is no mask involved.

They should be 4Mx1, so 8 of them on a SIMM would be 4MB. I think.

That gets a bit funky since self-expanding executables are applications, and have resource forks. So if the transfer is transparently taking care of resource forks for you, you could set the Type code to APPL for application, and the creator code doesn't really matter. Then just run it. But...

Just a couple additions: In zterm, under Settings -> General Preferences, you can set the type/creator codes zterm uses when creating the documents. Type SITD, Creator: SIT! is what stuffit uses. If you need a localtalk/ethertalk printer bridge, I've got a spare Farallon EtherMac iPrint...

Yeah, using the zilog chip is really the way to go for handling the wire protocol. I looked at bitbanging it from a uC, and it just doesn't make a whole lot of sense to do that unless you really have to. There are still SDLC capable SCCs available out there. I've looked at trying to make an...

Right. And I'm saying it works. I've got a mult-terabyte netatalk server that mounts fine with system 3.3 on a 512k. File size and volume size reporting is off, but it doesn't affect normal operation. As for NFS, the linux kernel NFS server is on the less compatible side of the spectrum for...

Use netatalk 2.2.x, and you can share via ddp (that's appletalk). >2GB works fine.

That's not mcdermd, I don't believe anyone wears that much eyeshadow.

Sorry, I've been slacking. It's waiting on me.

Yeah, I have a laserdisc player specifically for the star wars trilogy. The star wars dvds have a "bonus disc" that has a non-remastered version on it. Going down the rabbit hole of the "original star wars" is a bit more than I can really take since there were several different "original" ones...

Well, I went ahead and did another revision of the pre-ADB/PS2 board to fix the DB9 wiring, and added an ADB port, along with a jumper. The idea is to use the jumper to select between pre-ADB and ADB output. This means another 3-4wks before it arrives. I figure even if no one else cares, that...

Looking at my plus keyboard cable, it's straight through, but looking at the handset cable I chopped up to make my test cable, it is (was) reversed. Yeah, that would be bad, since power and ground would then be swapped. So, yeah, don't use a handset cable and thanks for pointing that out. I...

Yes, I'm using a stock plus keyboard cable. It's just a straight through rj11 4p4c cable, also sold as a phone handset cable.

That is my intention: to make all of this available to anyone that wants it. The PS2 keyboard/mouse to pre-ADB setup (with programmed stm32f0discovery and mouse cable) is $20 + shipping. You'll need your own mini-b usb cable to power the board. However, please read the comments above about...
