Strangely with mufastrom my IDE speed is 2.6MB/sec which is less than others seem to be reporting. I did think I had a 2mm 44pin IDE header but I only had a female one, so had to stuff some pin headers in there to get the cable to attach - could be noise from the extra connections?

Oh, and CPLD gets hot in all three systems - so I guess normal?

I have similar results on SD card.
600k vanilla or 2.4-2.8MB with fastrom.

So your CPLD gets hot too?

I wonder if it's only those with cool CPLDs that have the 3.5MB/sec IDE speeds.

Not complaining about it, just trying to head off all the queries that come when the board goes in to mass production.

I get around 2.5 and stay cool.

Well there goes that theory :?

My cpld is cool. It may be related to my sd2ide

I'm using sd2ide as well and hot cpld - so there goes that theory too :)

EDIT: It's not my mufastrom, SD Card, or SD2IDE adapter, as if I move the exact same card/adapter over to the TF534 it's 3.6MB/sec there.

Finally got mine built and flashed.

I've got it booting Diagrom on the H4 now, will give it a go in an Amiga later on.

My build works like a charm with latest firmware. Tested on A500 rev.6A. With original firmware from github I was getting unexpected crashes exactyly like allenppc and others.

This is now my ultimate A500 Turbo card. Photos will follow, I need to clean it properly, add missing caps and sd2ide.

TF keep up the great work and thanks for your effort!
When you're ready to sell I will definately order some more boards and maybe at some point in time we'll test 128 MB version just for fun:)

Good job! In case there's some space in the cpld/pcb:

-2 extra pins for IDE signals (just like tf530), just to have future option of faster ide speeds (although 2.5MB/s is good for me). Even if you didn't prepare a firmware for that maybe someone with experience does (Matze?).

-SPI for vampire-like ethernet, or spi stuff like audio cards that play mp3, usb...? CPLD seems big enough to handle SPI and with all that extra ram running tcp/ip stack and some network apps/games like "Dynamite" could be fun. You already wrote code for that for TF530, perhaps some parts could be re-used.

PS: I would be very happy even with 0 changes. Thank you for your efforts.

There are no spare pins unfortunately. It was a cram to get this all in .
