Not only 2 modems, but 2 modem posts! Here's the inside of the Microcom Deskporte FAST modems from the last post.

Inside of the plastic case is coated in a brown conductive paint. The modem chipset is a Rockwell 288DPi, using what appears to be a Zilog Z80 to manage everything. The main difference between them seems to be where the components have been sourced from.

So since I missed #ModemMonday last week - Here's two modems!
This time, they're Microcom Deskporte FAST modems. One branded by Banksia (local Australian distributor for Microcom) and one only branded Microcom. I suspect the Banksia branded one is slightly newer, but not by a lot. The Banksia is marked "FAST +" while the Microcom is just marked "FAST" with a "tm" after it. I think this was simply a branding thing between these modems, though it's possible one of them has later firmware or different internals.
These modems supported MNP from level 2 right up to level 10. They even had a parallel interface, in case the serial interface wasn't up to the task of keeping up with the modem, though you'd use the serial port to do things like dialling, etc.

Going to try and post a Modem Monday once a week (I own 30ish dial-up modems and a bunch of modem and comms related stuff).

Will probably post a bunch of computer restoration bits and pieces as they happen.

Repost from my other account: The CP+ Telecoupler II (there were a few brands of these on the market). You'd put it on a phone handset like an acoustic coupler modem, then plug the RJ cable into your traditional wired PSTN modem (an external modem, or say a modem built into a laptop), effectively making the pair into an acoustic modem. They had their own 9V battery inside to run all the bits so the wired modem thought it was actually connected to a real phone line.

Ok, so I'm gonna start posting more retrocomputing/retrocomms/modem content here rather than on my main @cefiar@chinwag.org profile. #RetroComputing #RetroComms #Modems #ModemMondays

@Rp12Biker Yeah I have a bunch of this sort of stuff, as pictured below. 😜 I used to run a multi-line BBS here in Australia (was called Cafe Chrome) between 1988 and 1996. At one point during that time, I actually worked for a modem company making/repairing acoustic couplers too. :awesome: #RetroComms #RetroComputing #AcousticCoupler #Modems
