AtariGeezer Posted August 5, 2017 Share Posted August 5, 2017 This is what I found on eBay a couple of weeks ago, but it doesn't have any docs or software. I know it's a long shot, but does anyone have any docs or software in their archives? Even in my library of over 1000 floppies, there isn't anything there for this... This is an original ad for it: 2 Quote Link to comment Share on other sites More sharing options...

AtariGeezer Posted August 5, 2017 Author Share Posted August 5, 2017 The Kamtronics software (which I own) only utilizes JoyPort 1 for radio control, The RM 1000 uses both ports (all 8 bits) for selecting the 3 RTTY Filters, CW Mode and PTT circuit and Data Input. I have been able to make a test program to configure PACTL for the correct POKES to PORTA to control it, but that's about it. 3 Quote Link to comment Share on other sites More sharing options...
+Nezgar Posted August 5, 2017 Share Posted August 5, 2017 I just listened to this a week or two ago - You would probably find ANTIC Interview 222 with Richard Watts interesting, who "was a programmer at Macrotronics, a company that was primarily focused on the RM-1000 radio modem" http://ataripodcast.libsyn.com/antic-interview-222-richard-watts-macrotronics 4 Quote Link to comment Share on other sites More sharing options...

But thanks Allan and Nezgar for the ideas so far 4 Quote Link to comment Share on other sites More sharing options...

_The Doctor__ Posted August 28, 2018 Share Posted August 28, 2018 (edited) Try Nov 79 QSTJ-Driven Macrotonics M800 RTTY in a search and see what you find... the rtty system should be explained and prolly near the same there might be home brew software or even an old ham with the disks you seek, so search out some ham forums and put the word out for specifically what you are looking for.

The Macrotonics M800 is an hardware kit for the trs-80. Will have to look for it I've been talking to other old ham operators an no one so far hasn't heard of the RM-1000. The joy port connection is what I have coded so far, but looks like I need to replace some op-amps and a few other IC's to get mine fully working again. An RTTY decoder is the first program I made using the Assembler Editor cart in 1984 Edit: found a copy of that issue and it describes what the m800 is...

AtariGeezer Posted April 17, 2019 Author Share Posted April 17, 2019 (edited) For reference, this is the Basic Schematic for the RM-1000 Radio Modem by Macrotronics that I made over the past week or so, I still need to add Part Values and update the component names,.. It looks like I have a bad 7404 the connects to the Computer Port, but now it will be easier to troubleshoot. Next up is to make aa program to use it, I'll probably start with the Split Window RTTY program by Rusty Lewis...

Curt Vendel Posted April 17, 2019 Share Posted April 17, 2019 OMG, I remember those! My friend did a service call in Brooklyn back in the 80's to get one of those working properly for a customer for his Apple ][ for the guy's business. I just remember helping with the antenna... the place was close the Elevated rail and that caused nothing but issues with the modem. 3 Quote Link to comment Share on other sites More sharing options...

atarilux Posted March 9, 2021 Share Posted March 9, 2021 Similar kit, although perhaps a little more up to date would be ideal for those living in Myanmar right now. The ability to bypass standard comms which can be turned off by the Government at any moment would be a huge advantage but would need things such as encryption... That said we know such things can lead to jail there. Quote Link to comment Share on other sites More sharing options...

AtariGeezer Posted March 15, 2023 Author Share Posted March 15, 2023 (edited) Finally got around to working on this about a month ago It decodes Morse Code and sends it as well. For starters, I am using parts of CodeWriter III for the CW Receive and the CW Send routine by Richard Watts' More Code Tutor. It's very efficiently written.... The RTTY routines are from Rusty Lewis' Split Screen RTTY program... I'll post a video of it in action soon...
