ESProFile - A Powerful ProFile/Widget Emulator and Diagnostic Tool
Lisa2:
I know this is a Lisa site but..
For fun, I tested a ESPROFILE with my Apple ///. Unfortunately it did not work. Good news it that no magic smoke was let out!
Using a blank 5M profile image, I tried to format the ESPROFILE with the SOS system utilities, but it throws an error and will not initialize. Then using BLU on the Lisa, I copied a known good A3 profile to the ESPROFILE. BLU was able to copy the data fine, but that also did not work on the A3. Also tried A3 CP/M but no bueno... :(
The A3 profile card does not use the VIA chip like Lisa has, I am guessing there is some sort of interface incompatibility. My X/Profile works perfectly on the A3.
If anyone has any luck with ESPROFILE on a A3 let me know.

Yeah, I've been waiting for someone to say something one way or the other about Apple /// compatibility. My Apple /// isn't with me right now, so I haven't been able to test it on one yet and I can't do any Apple /// debugging at the moment, but I'd like to look into that once I get my hands on it again.
The Apple /// sends faster strobe pulses than the Lisa because it uses DMA to transfer data to and from the ProFile, so it's basically the worst case in terms of emulator compatibility. I've never actually measured them, but I believe the strobe frequency is about 1MHz. I'm 99% sure that's what the problem is, but the only way to know for sure is to hook up a logic analyzer and start messing around!

Just a quick update: I noticed an issue where I would sometimes experience some weirdness when using ESProFile with parallel cards under certain OS's in certain configurations, and I was able to trace it down to a simple issue involving the timing of the BSY signal. The parallel card just expects it to be asserted much more quickly than the built-in port. And I have now fixed that problem, along with adding a couple SD card-related optimizations to improve disk access speed.
If you've had any problems with using ESProFile on a parallel card, go back and download the latest firmware, and you should be good to go. I actually fixed this problem about a week ago, but I just wanted to make an annoucement since people probably didn't notice!
ried:
Alex, your ESProFile is becoming famous!

Yeah, I saw that this morning! He was originally planning on making an ArduinoFile, but I reached out to him in December and sent him a prototype of ESProFile instead since it's so much better and more reliable.
It's a shame that he's having some problems installing LOS, but I emailed him about it and hopefully we can get it figured out. I'm pretty sure that something's wrong with his Lisa as opposed to his ESProFile because I tested that board in a 2/10 before I sent it to him and everything was working fine. Plus, I know of plenty of other people using them in 2/10s without issue. But I'll definitely let everybody know if we end up finding and fixing some kind of weird bug that only shows up under really specific circumstances!
