Hi all, I've finally got my Ultrasatan up and running with my Mega ST4 and TOS 1.02, and decided to go for HDD adapted games. Tried a few with intermittent success, and then discovered that ICD driver is not supported with Gamex. So I have gladly switched to PP driver as it offers DOS&TOS support for big partitions apart from Gamex compatibility. I am also pleased to say that the support from Peter was extremely quick and friendly. Partitioning and formatting the same SD card, and installing PP driver on it was a breeze. My Mega ST4 boots happily and sees new partitions just fine. And it is very convenient to have disk C as big as 255MBytes, seen from my Ubuntu PC without a hitch. I have started filling the disk with software. Brought a few ZIP archives to be unpacked with STZIP, however unpacking took seemingly longer than it was with ICD setup. At some point STZIP crashed with rather peculiar message, which unfortunately I did not care to capture. Thought I'd first copy a good 80M of game archives, which I did, and then the system froze while listing files in disk C. Hmmm. Long story short, I have decided to see just how fast Ultrasatan was. Using AHPT94.PRG utility I have measured both the Hardware and Logical access transfers, which turned out to be ~186 KBytes/s. The access time for Logical drive was around 50ms which I guess is not at all that fast. Any clues as to what could be the reason for low transfer rates? I've tried a smaller SD card, partitioned again as 255M for Disk C of type C16, it did perform roughly the same.
Hey Folks: This is my current setup , I do believe I have it all working perfectly, in the picture you will see a P233 with Atari Portfolio card reader, an Atari Mega ST4 with monochrome monitor, 2 PC desktops, and an Atari Portfolio hooked up to a parallel interface on my older IBM ThinkCenter.
