I'm trying to think of a way of getting hold of some ZIP chips. I have this Alfa Data HD for an A500 that can take ZIP chips for an extra 8 megs of ram, the trouble is finding zip chips to put in there.
So far the only way I could think of getting at ZIPs was to get them off some other board, possibly a case of desoldering them.
Any better ideas?
-
I think Mr. Hardware (http://www.mrhardwarecomputers.com) sells ZIP clones. They're expensive, though.
-
Looks promising. Many thanks :)
-
If that fails try a google search for Castle Computers. I am quite sure they will sell ZIP chips brand new as they are an Acorn dealer and some Acorn models use these chips. :-)

@Scumble
We have these in stock at Computer City. If you like I can look up the price. It's the 4mbit version as also used in Amiga 3000.
Best regards,
Ron

That would be most helpful Ron, although they aren't 1MB ZIPs are they? I'm not sure if this is a problem or not, as I don't know how these things work on the expansion bus.
Re: HopperJF - It doesn't appear that castle sell ZIPs.
It's a bit tedious that I ended up with ZIP sockets - according to amiga-hardware.com some of the AlfaData IDE interfaces came with SIMM sockets.
I've also read somewhere that ZIPs weren't very good for some reason - high failure rate or something.
-
@Scumble
Right, these are 4mb's. You have the 500RX right? The 500RX takes both kinds, only you can't mix them. So, you could install up to 8MB of the 4mb ZIPs when you take out the 1mb ones.
-
Just to clarify, it's one of these units: http://www.amiga-hardware.com/alfapower.html
Also, I have no ZIPs installed.
I'm getting confised with the megabyte/megabit abbreviations. Are we actually talking 4 megabytes on the ZIP? Sorry if I seem dense, but theres a big difference!
-
@Scumble
Yes, that's the RX500. These Zip's are called 4 mbit, not mb.
8 of these ZIPs make for 4 MB Ram. We used to sell these sets for € 34,99 but I think we'll discount them for € 25 a set, if you're interested, or € 45 for 16 pieces (8 MB)
Cheers,
Ron
-
btw I think the RX500 is actually the Supra memory expansion, my mistake. But the ZIPs will fit in the AlfaPower controller. We used to sell a lot of these.
-
Not bad, but there is only room for 8 chips. An extra 4 meg is more than enough though. What about shipping to the UK?
-
i have an octagon scsi card, with no ram on it, does anybody know if these cards take zip's and what configurations, and how much
-
@Scumble
Hmm only 8? That's weird.
Shipping to the UK is about € 5 if we use standard mail.
-
@JJ
The Oktagon takes ZIPs too, very likely the same type. Do you ahve a manual so you can check?
-
Yes, the Oktagon does take ZIPs, the same type as the A2386 bridgeboard, so I think the same type as the A3000.
Only thing is the Oktagon is a Zorro-II card, so if you're using anything faster than a 14MHz 68000 or so, you're slowing your machine down...
-
Palpatine - I'll have to check the board again. Last time I looked I didn't really count them.
Spirantho - I'm just running a normal 7MHz 68k, so it won't matter. I often thought that A500 accelerators are a bit of a waste, especially GVP's '030 one because you still have to use a slow 16-bit bus...
ed - I just realised that was a reply to the wrong question
-
@scumble:
A500-accelerators are definately not a waste, they will make your old A500 fly compared to stock performance. Almost all accelerators (GVP included) have onboard 32-bit fastmem and will only utilize the 16-bit bus for accessing motherboard resources such as chipmem and thus the cpu-performance wont suffer.

But I don't think it would make much difference in graphical performance? I'm not clear on how much the CPU deals with - I guess the Workbench applications would be much better.
Generally the trouble is finding A500 accelerators - it doesn't seem that many people bought them.
-
@scumble:
The graphical performance of the chipset is ofcourse the same. Though keep in mind that when using something that requires some cpu performance such as the Workbench or a flight-simulator it is not the performance of the chipset that is holding it back and making it feel slow, it is the performance of the cpu. As I said earlier, it literaly flies when using an accelerator, especially when using the Workbench - take my word for it. If you yet havent tried out an accelerated Amiga, it is something you need to write down on your "todo-list" :=).

I've checked and there are indeed 16 ZIP sockets. I'll probably be fine with 4MB worth though - I can't see a use for an extra 8MB right now. How should I place an order?

I would go the full 8MB, I've only got 4MB in my A3000 and it isn't enough for playing several WHDLoad games, I'd love to get the full 16MB but I was recently quoted AU$400 :-o for 8MB worth of ZIPs alone. My only other option is to go for an 040 board that supports SIMMs, but I don't like the idea of an 040 because of compatibility issues. Decisions, decisions...

@Scumble
Easiest way to order would be through our webshop (http://www.computercity.biz).
I have just added the product item here (http://www.computercity.biz/product_info.php?products_id=2474&osCsid=3be7fd846a515914cb96e738dde8acdc).

So, can two of those 4MB sets be used on Oktagon 2008 to get 8Mbyte RAM, for 50euros? (wanna be sure)
Where is computercity located?
-
@Orange:
It should, yes.
We're located in Rotterdam, the Netherlands.
The amount of stock available is limited though...
Cheers,
Ron

Ok Ron, I put through an order for one 4meg set. The shipping came out a little more, at 9 euro. What's the deal with the VAT? You still have to charge it for international orders? Although, considering it's the EU I suppose it works slightly differently.
-
@Scumble
Thanks!
Is the 9 Euro ok for you? It is 9 because that method is an ensured shipping service, we can also do it for 5 but without insurance.
The € 25 price already includes the VAT, we can only ship at 0% VAT to companies with a regsitered EC VAT number...
Cheers,
ron
-
Ah yes. I didn't quite add it up right in my head. The postage is no problem, as long as everything stays intact!
-
Ron,
Any update on the order I put through?
