Amstrad CPC 6128 - RS-232 Communications

- In this video I take a look at an Amstrad RS232 expansion by Pace. I do a brief teardown and describe the essential parts in the RS-232 exansion hardware. We take a look at the manual and Telecom Gold MicroLink documentation. Then I display the included ROM software (Viewdata, Honeyview, and terminal programs). Finally, we use a DMM, logic analyser, and finally a PuTTY terminal to see if we can transmit data from the Amstrad CPC to the Notebook computer.
In this video I reference: the CPC Wiki:

The first video in the Amstrad series is here:

I can't find part 3 - sending data back to the Amstrad. This makes me sad :(
About time someone did a non game orientated series of vids for the 6128, many thanks!
for terminal connections like this, enter key is not used for chat. just press down key.
interesting approach, you could also transform a 3.5 floppy and connect it to your cpc. also for simple basic progs you can built a tape cable and save your file to your pcs sound card with the proper software or just as wav.
Awesome stuff, a definite nostalgia hit. Cannot wait for the next episode.
The second connector is not for the European Schneider version, which I have at home. It’s simply a pass through for a second add on, to be able to connect supplementary hardware! Cheers
Cool stuff! I remember the good old RS232 days. Even today a lot of the business PC's have a serial port included. Most if not all of them are the 9 pin sub D. Good luck on your file transfer project and thanks for sharing.
The second connector on the ribbon cable is a through-connector to allow you to plug in another expansion device.
Just discovered your channel and would love to see this series concluded! transfering a whole book's worth of data is no small feat and I'm very curious to see how you went about it.
The computer has travelled halfway around the world from Australia to Japan, so I'll have to dig it back out one day and make that video.
I can't promise when, but it is on the long list of things to do. :)
@@NearFarMedia Would be awesome if you get around to it. : )
Is there some kind of follow-up coming? I'm curious how you tackle the book data, what file format it's in and the conversion .... ;-)
Kind of related. I believe the Oliver Twins (of Dizzy fame) created a device to enable them to type on the CPC and send the byte over to the ZX Spectrum as the keyboard on the CPC was far superior.
damn that were unthinkable things back then!
Might be worth looking into the XMODEM protocol (en.wikipedia.org/wiki/XMODEM). I used it a lot during the early BBS days for downloading files. You should be able to send a whole binary file from the CPC using XMODEM into a serial terminal on the PC, with error checking (a quick Google suggests that TeraTerm should be able to receive files via XMODEM on the PC side)
This is an awesome project!
That was interesting ! thanks for sharing, I almost feel like buying one of these expansion packs for my Amstrad collection, and connecting it to my surface book 2, it would be great if you'd list all the hardware you used (the adapters etc) so we could purchase them on ebay, thanks ! you have a new subscriber.
Wow that Amstrad looks suspiciously like a Spectrum +3. Alan Sugar was a cunning man back then...
...the Spectrum +3 was designed, manufacturers and sold by Amstrad, years after the 6128 was launched.
He was cunning to buy out Sinclair for cheap, while they were struggling then relaunch the most successful of their products.
Parity none, because you had 8n1. Abd file transfer we used xmodem in the 80/90s. It’s more robust than ascii especially with larger binary files as it also has a block recovery. So when connection lost, you resend only the last received block and the rest.
Millenials know nothing about old communication hardware and protocols ;) They don’t even solder their own null modem cables any more :P
Also check out the Ansiterm Comm's software from NZ, you might find it of interest/useful
I take it you have not found the time, managed to do it or abandoned the file save.
One thing you had XON/XOFF set, so you should have both the transmit and receive pins wired. Because XON/XOFF sends stop/start transmit commands if the buffer gets full on the receiving unit.
so... what happened to the conclusion of this string of videos?
If he didn't RTFM and failed then it is his own fault 😁 The XModem transfer protocol he found would do exactly what he wanted with ease
It's been a year now, have you abandoned the project?
Nice but it is an AWA, not an Amstrad... ^_^ Have you shared those video at CPC related forums (CPCwiki) ? very interesting.Could we find the microlink booklet scanned somewhere ? Concerning the second "male connector" on the ribbon, it is so you can plug other peripherals alongside this one (it would simply reproduce the male edge connector of the CPC) or if you want to use a longer cable in female/female configuration perhaps. German/later models had proper centronic connectors.
Are we still waiting for the next one?
Coming soon when we are back from an overseas trip! :)
So what happens next?
I'm so interested in this project! Please make it happens :D
@@NearFarMedia and ? are you still on trip ?
@@onurolce I think he's just waiting for the data to finish transferring at 300 baud then he'll upload the video!!
Really interesting videos! When's the next one coming?
+Pidde Bas Next one should be out this weekend. I'm glad you're enjoying the series :)
Awesome!
Will it come? or you just abandoned the project? Cheers
@@NearFarMedia Wow 2 years ago.. just found the series again. Is there a conclusion to this?
