I wanted to share a success story - the ADAM paired with Jim Drew's WiModem232.

 

Of course a lot of C64 users know Jim for the WiModem, which allows the computer to access the Internet over WiFi in order to telnet to the various BBSes that are accessible that way.

 

Several weeks ago I learned that Jim was designing an RS-232 compatible version of his WiModem. Thanks to Micro Innovations' MIB2 Parallel/Serial Interface card, I was ready to see if I could take the ADAM "on-line" and access the growing world of telnet-accessible BBSes. I was already using the MIB2 for dial-up modem access (via a Hayes 9600 baud modem), and was hopeful I could use it for the WiModem232.

 

I ordered a WiModem232 shortly after they want on sale around Christmas, and it arrived yesterday. The version I chose came with an OLED. Jim was confident that it would work with any computer with an RS-232, and his confidence wasn't misplaced. Following the instructions in the manual, set-up was a breeze and I was using the ADAM for BBS glory in no time. The unit is powered by a USB-USB mini B cable and a smartphone wall adapter.

 

If you have a serial adapter, it might be time to join the BBS community again!

That IS intrigueing; I remember back in the 90's when the net was a baby, the ADAM could get onto the web.  It was smokin' fast, but lasted way too short a period before the graphical interface came on the scene and left the ADAM in the dust.  What is available ADAMwise out in the ether?  Any users with ideas or something?

Nice! Where can I get the parallel adapter?

Thanks for sharing!

 

I just released a firmware update that corrects a race condition that has existed since the first WiModem for the C64 was released.  Update your firmware using AT*UPDATE

I'm not sure if all products cited are available, but there are two serial card options listed on the ANN catalogue:

Can you share specs (diagram/pictures) of the cable you are using from the MIB2 to the WiModem232?  Is the serial port on the MIB2 the same as the MIB3?

 

Also is that ADAMLink V you are using?

Yes, I'm using ADAMLink V - I think the specs for the 2 and 3 are the same - I'll have to dig up the instructions. The cable was rigged up by Micro Innovations - I think the provided a pin-out diagram in the instructions. I'll edit this message when I have the info (unless someone else beats me to it!)

Adamcon has two Serial Interfaces available on his page:

- Eve SP-1 Serial / Parallel Interface Unit that connects externally to the side Expansion Interface and comes in a plastic housing with ribbon cable to connect to the Adam.

- Micro Innovations MIB2 Interface Card that plugs into Slot #2 internally and provides 1 Parallel Port, 2 Serial Ports and Memory Addressor function for 256K on up Memory Expanders. Unfortunately, Slot #2 does not provide the necessary power for this card and you have to run the attached power adapter to the 9-pin plug on the left side of the Memory Console where the printer connects.

I didn't see parallel or serial cables on the site, but he might be able to make them or have spares available.

The MIB2 might be the way to go since the second serial port can facilitate attaching a Serial Terminal for displaying 80 columns in T-DOS or CP/M and there are a plethora of telecommunications programs available.

Anyway, pretty cool to see the Adam using a WiFi Modem and accessing Telnet.

Anyone interested in making there own Serial Interface can download the Micro Innovations Dual Serial Interface (Slot #1) schematics, silkscreen, firmware, etc. from the Coleco Adam Facebook group or I could post em here when I have the time.

I have a MIB3 but never got cables with it.  The docs are also incomplete and don't list all the pinouts for the serial port.  If "The Evener" could provide pinouts for his cables end-to-end that would be worth documenting.

I'm not sure how useful it will be, but there is a scanned copy of the MIB2 instructions for your reference.

If you could post the info here when the time is right I would appreciate it - I'm curious about this solution as a project

Very nice deployment of the WiModem232 on your Adam.  Man, I remember working as a young man in college in a computer store selling the Coleco Adam as fast as I could bring them down from the storeroom.

 

BTW, I just finished a case for my WiModem232...

Great story about the Adam! Must have been an interesting job lugging those boxes down.

Wow, that case looks sharp!! Please PM me if you're opening a side business selling a few here and there :)

Here are all the tech files that I have for the Micro Innovations line of Serial Interfaces, however I did not come across any info about the parallel and serial cables. I'll keep looking. The Dual Serial Interface Card installs in Slot #1 and the MIB2 / MIB3 Interface Cards install in Slot #2.

Thanks for cross-posting this info! I was curious about the dual serial interface in Slot #1 - does it need an external power source as well? I don't know my schematics about the different ADAM slots, but I see that the dual interface .jpg shows a spot on the PCB for DC power connection. It would be great to have an internal serial card that didn't need external power, but I think that's probably not possible.

The M.I. Dual Serial Interface Card DOES NOT require additional power... it's is provided thru the Expansion Slot that the card installs in.

 

The only Interface Card that installs into one of the three internal Expansion Slots and requires additional power is the Micro Innovations M.I.B. 2 and that is why M.I. released the M.I.B. 3 about a year later after resolving this additional power requirement of the M.I.B. 2.

 

I think Micro Innovations provided this additional power option on some of their Interface Cards including the IDE Interface Card that MicroFox Technologies started manufacturing again about five years ago and has been selling in the IDE CF Card Package. In fact, an AtariAge member modded the IDE Interface and CF Adapter to remove the need for an external power supply by drawing power for the CF Adapter from the IDE Interface Card.

I got the Wimodem232 today and it works great.  I'm using it with AdamLink V and the Eve SP-1 Serial/Parallel Interface.

That's great news! Nice to have a confirmation that the modem will work with the Eve SP-1 - see you on the BBSes! :)
