GBS-8220, 23DB Connectors and Leads
Firstly I just want to say sorry for asking all this again. I know this has been covered quite a long time ago and I have been reading all the threads here that I could find on the subject. I just wanted to ask some questions fresh to make sure it is still the current line of thinking.
1. Is the GBS-8220 still the best board to use for running old Amigas on modern monitors? 2. Is this still a 'build your own' project or does anyone sell these already made up? 3. Can someone supply the required Amiga to GBS-8220 lead already made up or do I need to make my own? 4. If making my own can anyone sell me or show me where to buy a D23 Female connector and hood? Maybe this is all old news now and some members have a better solution? Thanks in advance for any help. |

I'm actually surprised that Amigamaniac or some of the other guys aren't offering this as a "service/package" yet.... But it's really not that hard to do... Even I did it.. ;-) desiv |

The converter is labeled pretty good
All pins are on Amiga side: PIN 3 RED PIN 4 GREEN PIN 5 BLUE PIN 10 CSYNC PIN 19 GND Edit: one more thing, if things don't work, press the "Auto" button, to find the signal. |
Thank you guys for your responses and also desiv for your straight talking answers. Good to know that this board is still the way to do things. I am now happy to order one of the GBS-8220 boards from ebay and hopefully kipper will be able to send me a connector and hood in exchange for some paypal cash.
Can I ask, do you guys make the lead up by cutting the end off an existing VGA lead or do you solider straight onto the board? I ask because I want to be able to disconnect the Amiga and connect other old computers EGA and consoles etc as well. If anyone has any images of their projects that would be a help. Many many thanks already. p.s. Is this the board I need? http://www.ebay.co.uk/itm/1809119379...84.m1423.l2649 |

The GBS has a VGA plug (or 2 if you get the 8220) and you just plug a cable from that to the monitor. There is also a header that goes to the Amiga. The GBS (at least mine and all I've heard about) comes with a plug for that header with some wires. I just soldered the the 23-pin plug to the end of those wires and was good to go. Quote:
But you could either just get multiple headers and solder different ends on those, or you could go from the header to a plug you make. Then from the plug you make, you can have different cables going for different machines and just plug in the one you want at the time. I know at least someone did that for his case for it. Not that he's using multiple machines, but he went from the header to a plug in his case. Then his Amiga cable went from the DB23 to the a plug end for his case. I'm only using my Amiga, so I haven't tried that. I am using the VGA end on a KVM tho. So my monitor is for my Amiga, or my PC or the 2nd monitor for my work laptop. (and one free for project PCs) Quote:
I think the only difference between the 8200 and the 8220 is the 2nd VGA port, which I believe is just for cloning (the same image would be on both screens). I have an 8200 and it works fine.. desiv |

I want to add something...
I put mine GBS in a standard box and wired the input to 9pin connector and made it compatible to 1084 monitor pin out. I can use standard Amiga monitor cable with my box, no need to hunt down hard to find connectors. See pics |
A very good idea and I was thinking of somehting similar myself. Can I ask why the blue input provided just in front of the header can not be used?
What type of connector is it? |
The VGA input you see is for 31khz video input.
For 15khz input, you need to use provided cable and use composite sync. Also, you can use the connector with 5 pins (R, G, B, GND S) with Amiga. |

Thanks for bringing this subject up again, I have been looking to order one of these to just test around, and as I was going to research the subject, I find this thread where I get a quick answer. It is the next best thing to Indivision. :)
Since I do hardware builds, I will make some nice box for it. If you have problems figuring out how to wire it, I can make a guide, but it is fairly simple. Or I can do the wiring for you, as long as you pay for parts and shipment back to you. To make Make it possible to use all screen modes, I figured I would just wire up a VGA cable along side the cable that feeds the board, and connect it to the VGA input. However, I just have to ask, does the board auto switch between inputs, or can you manually select which input that should be used? |

be careful with EGA.. most of them output digital signals (TTL) which may not be compatible with that 82x0 thing..
|
That is good then. It wont flip out because I wire it up to be able to run 31khz modes as well :)

Johan,
Instead of me buying the parts on ebay and making it, would you be interested in making another for me and I will pay you instead? I also want to repeat that I also found the help here superb, my questions were answered very quickly and professionally. Thank you all. |
I have checked around, and there is some interest in having these built. So I will order one and see what I can do, find a good design. Then I will buy some more boards and do some of these to sell, will not be expensive, parts + shipping + small fee for the work of soldering and working on the boxes to install the boards. I will post a message on this forum when the boxes will be available.

Get in. Looking forward to this. Only problems is I might not be able to wait.

Biggest issue will be finding 23 Pin Dsub connectors. I can always cut 25 pins to 23pins, but that does not look so nice. |
Hot Trout: It might be best if you go ahead and get yours from where you can get it the quickest, because delivery time will be rather long. About a month and a half before I have the boards, and then about a week or so to make the prototypes.
