Amiga 500 4/8mb fastmem boards with IDE

[MoreBITS]

I am trying to figure out if my previous post have been missed, or if I am not following the right process, but I don't see my name on the list anywhere. Please let me know. I am interested in an 8mb card.

Hi,

I'll add missing names to the list, no worries, if your post is in the thread you will be looked after in chronological order.

I have to apologise for not sending out emails the last couple of days. I have the boards ready and i forgot all about the adapters so i got the headers i needed for them and they are done. I'll send msgs to people in the next little while.

(I'll also empty out my PM box too a little

One last question before I proceed with payment since I'm in the next batch of buyers. Will this expansion work with my Alfadata RA5-2M ram and how much would be the maximum Chip/Fast ram I could achieve with my rev6a A500? Could you possibly make a guess Brian?

I have seen the old kipper2k 8MB expansion work together with the Alfadata RA5-2M (without CPU adapter) to provide 0.5MB chip and 9.8MB fastmem. If you have the version with CPU adapter, I guess it should work, giving you 1MB chip and 9.5MB fastmem.

Hi All,

PM's sent out to 15 people and the first post updated to reflect current status. if you have recently declared interest and not on list no worries, i'll work through it later

One option if you think that you may have memory conflicts is to buy an extra CPLD that does not enable autoconfig so you could manually add memory. extra cpld programmed with no autoconfig would be $4

The a500 rev6a can support 1mb chip mem i believe... Can someone confirm please

Many people have done the mod on the 6a to get 1MB chip mem using either 512kB in the trapdoor or by soldering in 4 extra RAM chips.

Please can someone meassure the hight from the motherboard to the top of the cpu after the expansion is on?

I can do that later tonight. It is not higher than the top shield though. I think it should be about the same as the old 4/8MB expansion. On this board though there is an issue with the 2 wires that need to go to the side expansion connector. The connector is quite tall and is the reason that the top shield cannot come on. I think I'll solder the wires directly into my board to avoid the issue.

Thanks demo
It's for the hxc project, I'm going to make a scaffolding for it tonight, but it might not be possible to add this expansion due to that.. Maybe it will fit a little higher, but need the measurement
