Let's finish the GBS8200 in Amiga 2000 EATX

- A couple of months ago I built a GBS Control mod onto a GBS8200 but also mounted it to a board so it could be installed within the Amiga 2000 EATX. On the day I left it with just a VGA cable hanging out the back of the case and while it works fine it left it very unfinished. Let's finally finish off the install by soldering on a VGA cable and printing a custom bracket to hold the card in place.

I have so much envy every time I see that tower Amiga.
Tidy with Glen!
I am very proud of this build.
Very nice lateral thinking mate. Well done!
Looks great Glen 🙂
Thanks
Wow, I've never given a single thought to how many of the 15 VGA pins are actually used.
Only 6! Of course, the 9 PIN connection of HGC, MDA, CGA or EGA would have been enough.
Presumably to make it clear that it is not compatible, a new connector was used.
But then why not before, MDA CGA HGC and EGA are not really compatible with each other either...
Thanks for the Video, nice job as always!
I like clean and tidy systems :)
That was a simple yet effective solution! Good job!
Nicely done, the Amiga shared the same bracket convention as the old ISA standard from IBM - so the bracket would need to be flipped in order to be inline with the expansion card. Intel changed the standard for new cards with PCI and reversed the orientation.
Nice work! I didn't know about this GBS8200 VGA mod for the Amiga.
Aside: I wish they'd designed the Zorro slot keyed for direction. I recently traded to get my first half-sized Zorro card: a GVP RAM card for my 2000... and, once, accidentally put it in backwards. The person that sent it to me had made a label on that read "CARD SLOT SIDE" (instead of "FRONT OF AMIGA" which I've since changed it to). In a confused moment I interpreted "CARD SLOT SIDE" to mean the side where the case has a slot exposing the card edge (i.e., back of Amiga). When powering on with the card in backwards, after about a second, the Amiga powered itself down (maybe detecting a short) and thankfully nothing was damaged.
The manufacturer had no direction printed on the PCB nor label indicating which direction to install it. *eye roll*
I certainly like that modern PCB designers realized there is a lot of freedom to print useful (or humorous) things on the PCB itself!
Thanks for reminding me, I forgot to link my original mod video, but it's on the description now.
I had that exact thought when first fitting the mod in the video slot which also isn't keyed, and there's no indication for which way it has to sit. It's not in the video, but I checked the position of ground with my meter before fitting the gbs mod just to be sure I had the orientation correct.
@@CRG Thanks much for the link - I hadn't found it yet!
well it does look fantastic glenn....i like the design of that amiga...oh and rodland and road avenger looked great ...both games are cool....
I like it, works well.
Have you ever encountered any GBS8200 units which output scrambled signals with sync loss, or pink video? I know multiple people whose GBS-C units are failing with this type of failure mode, and I don't know what's causing it.
on a normal gpu the bracket would be in the slot below the card
Hello love your channel ❤ a question the A2000 is it a normal mainboard from a a2000 case or a a2000T if there is a (T-model) i have 2pcs of a2000 compleet might build a tower in that case
There wasn't an A2000T, rather this is a modern reworking if the A2000 into an EATX form, hence why it fits in this modern pc case. The original 2000 board wouldn't fit.
Glad to hear you've been enjoying the channel, thanks for the support.
Does the pistorm hdmi output disable when using the amiga's native output?
No, the workbench screen remains on the HDMI output.
I'd like to see an HDMI solution using one of Macrosilicon's single-chip RGB encoders.
do you mean quick sort, merge sort, radix sort, or some other form of sort
I've no idea what you're talking about?
just sorting algorithms for coding, that kind of sorting of things@@CRG
Why not use a connector?
Yes I could have ordered something but I had that cable lying so why not just solder it up. I don't see me ever removing it.
Why not just use an RGB2HDMI?
Just wanted to do something different. The board to mount the gbs in the 2000 was gifted to me and I'd been wanting to try gbs control so why not. It does produce a fantastic image. You can see direct captures in the gbscontrol build video.
