Clockport-Adapter for A500/A1000/A2000/CDTV

[Doobrey]

@Stedy,
 It latches the lower 8 data lines too, not 100% sure if it`s really needed though.

BTW, I was fiddling about with clockports the other day, and figured out there`s enough space within it`s 64Kb memory space to have 1024 clockports... (2^10 cos there`s 10 unused address bits within the 64Kb)

 I wonder how much discount Jens will do on 1000 silver surfers ?
OK, bandwidth would suffer a bit, but it`d be fun to make an adapter that size  :lol:

Sorry, kits are not available.

They were planned for February.
February 2000, that is.

Sorry for not updating you, but I have recently become father so I'm a bit distracted.

I am "working on them" to get some things done.

They do not respond to emails, but they read them, so keep them telling youre interested.

I am after them by phone

And yes, that PCB is a very very simple one with very vew logic on it.

But the *.ps shows only the board itself I thing, it's almost useless.

I'll get back on this topic.

Have fun,

Hi

for those of you, that wishes to have a clockport in an A2K (or A3K like me), there is a relative cheap method to get one:

I've been nerved by the two reboots of my A3000T at every cold-start, so I decided to buy a "Kickflash OS4" from Individual Computers. I've ordered it last Tuesday evening and half an hour ago it arrives.

This card works in every Amiga with Zorro-II and has a clockport. The documentation says that drivers for Silversurfer, VarIO or Delfina will be available soon :-D

I will go offline and open my case and test it, lets see if we could speed-up system-start :-)
And than lets have a look to eBay, maybe someone want's to sell his Delfina...

Hi McTrinsic,

Sorry for not updating you, but I have recently become father so I'm a bit distracted.

Hey no worries and congratulations :-)

If I designed my own variant of this adapter and got some PCBs made, what would the interest be in kits of PCBs?

Earliest I could make prototypes would be mid May 2004.

For quantities of 5 PCBs or more they cost around 10 euro each.

bye,

Ian

Id take one - but only the complete adaptor, i cant solder myself.


Have fun,
McTrinsic

Ok, I got few news.

Looks like they might have a few prototypes left, can't say the actual number but maybe around two or so. Might be not working, one of them is going to check them.

The schematics have still to be dug out of the belly of the computer system of one of them. But he is working on it, so in case the schematics (circuit etc.) appear, you will be informed.

We shall then see whats possible

Haver fun,
McTrinsic

I'd be interested to see the schematics. One of the parts they used a 74F521, is tricky and expensive to get hold off. A redesign might be possible.

Keep us informed.

Farnell have them for 50p each..
74F521PC

But I know what you mean,
You could replace the 521 comparator and the NOR gates with 1 GAL/PAL chip.
 Should even be enough spare logic to decode the address space and generate 4x Spare_CS and have 4 clockports  :-)

Sorry for the thread necromancy!

Does anyone know the status of the Clockport Adapter? I recently got a CDTV and would really appreciate a faster connect than the 19200 bps (or whatever the maximum is using BaudBandit.device &c). I have emailed Katodev but haven't received any response.

[Cyberus]

'thread necromancy', heh, I like that

And that's precisely what I'm doing, as I would like to know.
Perhaps McTrinsic's littl'n is keeping him busy?

[Cyberus]

:bump:

Did anyone get any further? :-)

Sorry for my lack of technical knowledge, but can´t you just plug a Zorro card like Xsurf into the side of the A500 (without external casing of course) and use the clockport on that card  :-?

In theory, yes.

[Effy]

So why waiting for a special clockport adapter for the A500/2000 if you can just plug an existing Zorro2 Xsurf(2) with an on board clockport that can allow you to use a USB card Okay, it does leave the question open about where to put the usb connector because there is no external case ... but the same problem occurs when you put the clockport adapter inside the A500/A2000 ...

Errr...
Why do you think?
Firstly, how much does a X-surf II cost?
Secondly, one would need an adapter to use a Zorro II card with the A500, since it does not have a standard Zorro slot - and there would be no case (although I guess one could be made)
Thirdly, most A500 users already have something in the 86-pin expansion slot at the side, such as a hard drive.

Find me a reasonably priced X-surf II, and then maybe I would take this route! At the end of the day, the A500 is purely a hobby machine, and I don't want to shell out huge amounts of money...I reserve that for my A4000 and A1200! :lol:

[McTrinsic]

Sorry folks,

I am after them, but they evade me

Seriously, I am in contact with one of the developers, but he is extremely busy at work and is flooded with spam.

So I am having a hard time getting through to him and get anywhere.

And another one is having the scematics.

So this really takes time, especially since I dont have much of it by myself with my little great kids.

Its so much more fun with them instead of circuits...

Anyway, I too want one of these simply because I dont want to spoil the design of the A1000 case.

I want it all in one



Have fun,
McTrinsic
