Amiga 1200 accelerator Vampire 1200 is now in Development

Psssst!!! Apollo Team haven’t forgotten Amiga 1200. It is on the move! A video of Vampire 1200 connected to the expansion connector on Amiga 1200 also shows some progress below.

In our Vampire V4 Standalone article. Apollo Team seems to be gearing up their development to release these new FPGA options for users that loves Classic Amiga. Now it is working as it should.

Majsta’s no more struggle with Card edge connectors

In the process of making Vampire 1200 I have found only one problem. Card edge connectors with 150 pins are extremely hard to find. Fujitsu made them and then discontinued in 2000. Now they don’t have replacement part. Original part number is: FCN-225J150-G/A. Connector itself is right angled with 1.27mm pitch and two separated sides. One side consists of 2×25 pins and another from 2X50 pins. Even building footprint for it was challenging.

As I see it here we have only two options either we search for NOS or we manufacture those connectors. So far I have sent anywhere between 200-300 mails and made lot of phone calls with every person who had in his hands connector at least similar to what we need here. Searched over old newsgroups, tracked down people who owned Amiga shops 20 years ago, talked with every card edge manufacturer or reseller in the World. Even talked to Fujitsu directly.

Most challenging was to read Japanese and Chinese web pages to be able to search their NOS. So far result is like this. In the existence there are 174 NOS connectors with insane prices and tooling fees with Sullins and Taiwan companies are huge for Amiga hobby projects.

What can we say about connector itself. It is not even standard connector as Fujitsu sees it, it is not even listed in their datasheet where all versions of FCN-225J were listed. This decision Commodore made created pure nightmare for any potential hardware developer. Even back then, when Amiga 1200 was designed official proposal was to use two connectors, one with 50 and one with 100 pins, but even that is not an option now because also those are hard to find at normal prices.

I keep asking myself after one week of constant searching for those connectors why did they make decision like that when lot of those pins are unused and any card edge connector with 120 pins could be used. Those connectors was standard then and they are standard now and probably they will be standard type of connectors in next 30 years. Another question is why they didn’t put just simple 2.54mm pitch male header. All of this only tells me that someone tried to play monopoly game on the market, to create distance from other projects but like history teach us in some areas this is not smart to do.

In reality put whatever you want inside box but for talking to outside world use exactly what everyone else uses. Talking about that makes no sense now, what is done it’s done. I don’t want to use PCI connectors and cut them because that won’t look professional and it is time consuming if you consider that we will probably need to make at least 1000 Vampire 1200 cards. It would be also too stupid to have DDR3 on board and in the same time connector who is butchered and then glued. I ll probably find a way how to solve this problem like I solved many others in past years but situation where you need to pay for a connector same price as you are paying FPGA is not an option for now simply because makes no sense. IMHO those connectors shouldn’t cost more than 5USD.

Quantity we have now is enough to do one small series of cards but what happens later?

Majsta got issues with the connectors before, but now it seems to be solved. What he did is not mentioned. I thought that this was the case until I saw when this posting was posted. The website got me! … Send Amitopia news updates about Vampire to post@distrita.com ! We want to help you out.

Get in touch with Apollo Team for further Amiga 1200 development

If you have any questions regarding what Apollo Team is doing. You can find the team on #apollo-team irc channel on Freenode.

Also you can goto Vampire Accelerators Users Group on Facebook.  I hope that Apollo Team will produce many Vampire 1200 cards and give the Amiga reborn a fully meaning for all Amiga 1200 users around the world.
