Thanks, bye!

Hi,

This card will interfere with the 2.5" HDD, you would need to swap it out with a CF card

@thread.

I have msged everyone who had a request in, if i missed you, let me know.

Hi Kipper,
I switched to a CF Card so I confirm my interest in your 4MB A600 Expansion.
Thanks.

Howdy!

I did a quick check on my A500 running the A590 with 2MB RAM and found the following:

$00E90000 (Size 64K) - A2091/A590
$00200000 (Size 2048K) - FAST MEMORY

I removed the RAM from the A590 and set the jumper to 0MB and it still didn't work. I don't think a 4MB RAM upgrade would work.

Maybe the A500 PSU can't handle the power drain?

I'm still having no luck with the CPU riser card. I just get a black screen. :(


Cheers,

Chris

The 8mb fastram board uses memory at locations $200000 - $9fffff, remove the fastmem board and do a memcheck, see what memory location the A590 uses. if it uses any range between $200000 - $9fffff then there is a memory conflict and the only option would be to either remove one or the other, or possibly use a 4mb board which would use uncontested area of ram

I tested my Kipper 8mb Ram upgrade with GVP530 and Ram disabled but it wouldn't boot (black screen)

So I guess some/many Side Car Ram/HDD expansions are not compatible at all?

I think once CF card IDE68k is integrated with the mem expansion the sidecars could be extinct :)

BTW... All order paid for have now been shipped.

I can hardly wait. It would solve all my A500 problems :thumbsup:

@Therad resoldering pins 1-3 on my Kipper 1000 adapter has fixed it, now my A1000 has 8mb Ram and I can still use the FDD :)

Thanks for redoing the soldering Steve, For some reason the solder silkscreen messed up and those 3 pins on the board were a little arkward to get a good bead of solder on them.

Thread should be all caught up, and everyone should have a pm to acknowledge interest.

No worries, any practice I can get soldering helps :)

They were quite hard to solder, even with lots of flux and good quality silver core solder it just didn't want to stick!

Thanks for producing these items, I can't wait for some kind of IDE :thumbsup:

(built in K508+IDE FTW!) I'd buy one tomorrow :cool:

Steve.

I'd like an A500 8mb memory board if still available. PM sent.
