I think perhaps you keep missing my point here :) I don't believe they did or frankly even care if APPLE released such a device, only that they included a provision for one. Whether a 3rd party (e.g., Global Village, et. al) ever did is a question I haven't been able to answer though. The...

I initially ordered 3 boards and have 3 PowerBooks, although one doesn't work at the moment. I'm also contemplating a slight remix to include a bluetooth audio transmitter board (KCX_BT_Emitter v1.1) in addition to the ESP module. Using a spare GPIO on the ESP and small revision to the...

   Sure, but were there any 3rd party serial modems offered for the Duo? Aside from those few obscure references that suggest the potential of such a device the Developer's Note, I've found no reference anywhere to confirm such a thing ever existed (although I'm certainly hoping it did, or was...

It's either that, modify ESP_SLIP_Router to bridge, or abandon it altogether in favor of what appears to be one or two available (but seemingly much less baked) bridging SLIP implementations. More research and fiddling required. Regardless of the path chosen, however, I'm still going to...

With year-end at work and holidays at home, I haven't touched my Duo since posting the above I'm afraid. I'm hoping to find some time after Christmas to pursue the theory outlined above pertaining to the possibility of a built-in concession for a 3rd party traditional serial modem. I really with...

TBH, I haven't benchmarked them owing to the fact that, as you surmised, they're "good enough", but I was encouraged to see the Samsung Endurance included in @miko-Tokyo's comparison. While certainly not the front-runner, it's adequate by my SCSI-1 equipped gear's standards and only really falls...

I'm definitely onboard :)  Great outline. I certainly agree with not rolling a custom IP stack. It'd be great if the eventual outcome was 100% physical-layer agnostic and leveraged whatever device is selected in MacTCP / OT. That's where all of the previous implementations seem to be lacking...

Can you provide some specifics about the cards you used from each manufacturer? Recognizing that the flash in most SD cards isn't particularly well suited for continuous rewrite and therefore use in an SSD application, I've been using a mix of Samsung's "Endurance" and Sandisk's "Max Endurance"...

Very helpful info, thank you! If nothing else, it's nice to know I'm not missing something obvious :)   I noticed that Rob's adev included the source and am staring at it now... As you suggest, I may be able strip out the uam portion and cross-compile something that meets my needs? Definitely...

I have what is probably an obvious question, but one I haven't been able to find an answer to searching the forum, Google, or via brute force attempts to make something work. I now have a small collection of PowerBooks connected to my LAN over wifi via SLIP and ESP8266-based serial modem...

That just leads to it trying to permanently eject. All 20 pins are connected in a red stripe, 9 and 20 are missing with yellow, which is what the 800K drive needs for use with a plus. There are a few posts here with pics documenting the differences. Using the cable I modified by removing 9 &amp...

I had a bit of a eureka moment on this topic yesterday. I stumbled across a more generalized "Macintosh Duo System" Developer Note that I hadn't encountered before on other sites: http://cdn.preterhuman.net/texts/computing/apple_hardware_devnotes/PowerBook Duo System.pdf Remarkably...

I purchased a dirty and untested Sony 800K mp-f51w-23 (I think it came out of an SE) as an internal drive replacement for my 512K (which is running Plus ROMs and a MacSnap).   After thoroughly going through it and cleaning / re-lubricating, the carriage movement is nice and smooth, but when...

@Trash80toHP_Mini Very interesting, thanks for posting! Just the DAA then. So using a dock's "modem" must seemingly require the internal modem? That would explain why there's a line in the above diagram going from the MUX to the expansion connector. @Challenger 1983 I believe the answer is...

Interesting! I like the idea of configuring the wifi and initiating the connection in one app via a single protocol, whether as you sought to do or as @techknight suggested above. That said, it's quite easy, once a SLIP connection is initiated, to telnet into the ESP and execute a single command...

+1 for TRS80's suggestion. It'd be awesome to see something SCSI connected in a 2.5" form-factor for use in any Powerbook that could do double duty as an HDD replacement and provide wifi ethernet.  #pipedream

Take a read through the other thread: "Of the numerous available ESP8266 boards out there, I chose the ESP-07 for its u.Fl connector. Reason being, the interior of the PB plastics are coated in a metallic RF blocking film and I wanted to route a higher dBi antenna up behind the display. Here's...

Thanks for the advise. The only trace routing near the antenna (and note, I'm using an external u.FL connected ant, not the on-board ceramic) is +5v topside and an unnecessary CTS pin headed to the RJ-11 underneath. The ESP module itself is also surrounded by a grounded copper layer on the top...

Hello! I just wrapped up a project over in the Hacks & Development forum that I though might be of particular interest to this crowd, so I'm cross-posting. TL;DR, I've developed a serial wifi module that directly replaces the internal Global Village modem. It only offers modem speed, but...

I've been playing with these "modems" now for a few days now, and have learned a thing or two: They're as slow as expected  :)  The results I was seeing from Fetch in PASV mode are consistent with additional tests I've run grabbing files via HTTP using LYNX and iCab. Max download speed is...
