Interested in another. Sending PM
Shipped to gmcn. Thanks!
Hi does this work with A500 Rev5? :)
Yes, but remember that you need Kickstart 3.1 or 3.1.4 and you can't use a rom tower. I have pics of how to rewire a regular 512K rom chip if needed.Quote:

Speed was horrible though, only 650kb/s, but after installing mmulib and running mufastrom it reached a must more respectable 3.5MB/s which I think is what can be expected here.Quote:

I notice that the silkscreen has printing that suggests it can also be configured with a buffered IDE interface. Is this an option that is working and will that improve compatibility?
Otherwise it seems to be running stable and all 64MB made it here from Canada so feedback will be incoming soon. :)

Yes, the IDE is a bit picky which is why I give you the heads up beforehand on how to maximize performance. :)
I have noticed the devices I tried it with tend to fall into three categories (all assume you are copying ROM into fast ram):
1) 6.5 Mb/s reported with Sysinfo - for example the "blue and white" 8gb CF card from ebay/amazon.
2) 3.5 Mb/s reported with Sysinfo - that seems to be the one you have
3) Less than 600 kb/s reported with Sysinfo, for example with some (but not all) Memory Partner 8GB blue cards (some actually fall into the 1st category).
The buffered IDE is an option to use long cables but it has been reported not to work with the A2000 fixed firmware so I haven't built any with this option, so it's better to use an external buffer (for example those made for the A600/A1200).
Kingston 4GB and Sandisk 16 GB cards also seem to go full speed for me.

It doesn't take more space than the original Kickstart socket + ROM. The author offered the PCB for 2 Euro last year on https://www.ebay-kleinanzeigen.de
Even though there's no current offer the Gerber files are available. (I think a PCB service from China will make these PCBs for 2 Euro or less.)
Are you sure about this one? I did manage to find one of the adapters that you specify and I also had one of those 8GB blue and white cards from ebay. It is also only about 3.3MB/s. There is a common problem with SysInfo that it tends to report 6,553,500 bytes/s or 3,276,700 bytes/s for fast drives. Notice the nice 'round' values (2^16 x 100). If the measurement finishes immediately then the measurement is wrong. I think it is a kind of division by zero that causes it to fail.Quote:

Oh, sysinfo is garbage, absolutely. These should really be measured with a real benchmarking tool like diskspeed.Quote:
