My A500+ Project

[Amike]

In the showroom of a1k.org you can find some interesting A500 projects. There is also an international section where you can post your questions about the projects.

It looks like an interesting site, but appears to be German language only.  Maybe I missed an English language option?

I used an A500+ with GVP HD8+ with two PSU's connected to two different sockets for years!

I would randomly switch off them in different order. I never had any problem, never had data corruption.

Hi again,

Was just wondering .. is there maybe a wireless adapter for the A500+ rather than connecting the Amiga with PC with a cable?

[pyrre]

Not that i can think of no...
At least not easy.

You can get a cpu socket adapter with clock ports.
They will enable you to use USB adapters like the subway USB
And in theory you should be able to use network adapters with it.
But..
the subway requires "Processor 68030 (25MHz) or higher" to work in amiga...

Hi people,

...
However I am scared of only one thing ... how do I switch the computer off now? I have two ppc supplies. Is it ok if I just switch the hard drive ppc off and then the computer ppc off or there is some other way? I am afraid I could damage the hard drive if I just switch off the hard drive ppc.

Errrrrmmmmmmmmm - first of all:
A "PPC" is a microprocessor (=CPU; called "PowerPC").
What you mean is an "PSU" (Power Supply Unit).

Regarding your fear:
Why don't you plug all your devices into an switchable multipoint connector?
This way you can switch on/off all your devices simultanously...

Hi Dandy,

Yes in my first post I wrote PPC rather then PSU :$ but I corrected it in my second post on that subject I connected everything to the same socket extension but still switch everything step by step as suggested on this thread

@pyrre
mmm ... let me see if I understand correctly all this.

If I buy a clock port then I would have to remove my CPU from the CPU socket, connect the clock port in the CPU socket, and then connect the CPU on the clock port. After that (if the CPU was powerful enough) I could connect a subway USB to the clock port which would allow me to connect USB stuff to my A500+ (including some type of wireless adapter). Is this right?

Now if the above is right. If I buy an Accelerator Card then I would connect this to the clock port instead of the CPU? or they cannot be chained?

[darksun9210]

yup, the clockport adapter plugs into the CPU socket on the mainboard.
the accelerator would plug into the CPU socket on the clockport adapter, and the old 68000 chip would plug into the 68k socket on the accelerator if you need it for backwards compatability.

however, you may find that stack of hardware means your keyboard doesn't fit right anymore ;-)

plugging a subway into the clockport adapter will give you USB on your A500 for keyboards, mice, usb memory sticks, CD drives, hard disks, etc. etc. and even USB>Ethernet adapters.

although, i don't know of any drivers for USB>Wifi adapters for the amiga, and there is something up with the hard/software of the subway and USB drivers for USB>LAN adapters (using the pegasus2 chipset - in my experience) that causes massive amounts of CPU interepts.
this results in slow screen redraws, jerky mouse movement, and transfer rates no better than a direct serial to serial connection. or even parallel to parallel using the old 68000 gives you 20KB/s...

it might be something up with my hardware config, but to be honest, since i can't figure it out, i've given up with my a500... :-(

@darksun9210

From your comments, even if I buy all the hardware required it seems nearly impossible to get that configuration working! So I guess I better find another alternative. Isn't maybe any wireless adapter which connect where the null modem would usually connect. If not how hard would it be to build such a device?

 

[Lockon_15]

You should try some other USB-Ethernet converter, some which use ASIX chipset. DLINK DUB-E100 has been reported as fully "Poseidon friendly". This info comes from people actually getting A500 online, so no rumors - take a look at A500/A600 showroom on A1K.org site.

[darksun9210]

sorry for the off topic, but just ordered a Dlink dub-e100.

many thanks for the heads up Lockon_15! :-)

Yes exactly like that.
except one thing. wireless. I have not investigated enough on this matter. but i don't know of any wireless solution for A500.
However.
I will embark on another solution for my A500+.
I have the trumpcard sidecar. It has two zorro sockets. and hopefully i can use the budda flash in it. the trumpcard does not have the buster chip. So i am really excited, will it work...?
And if the budda works. then i will try adding a subway, and hopefully i find some network adapter that works with it...

@Lockon_15
I entered in the international section of the A1K.org site, but I did not find any A500 section. Do you mean I should ask question about the A500+ on that forum?

... also; so I cannot maybe find/build a wireless adapter which I can connect instead of a null modem?

[Lockon_15]

Take one more shot...
