Wow, that´s a nice picture!

And I can clearly see my PARCP-USBs :D

Great job!

I'm posting this picture to ensure you the PARCP-USB is indeed being shipped. This is actually the fourth batch. You can notice the two items at bottom right are still free ;)

Why don't you try and sell one on E-Bay? It's such a good device so I'd be surprised if there wouldn't be a demand for it. Perhaps even enough for another batch?

Thanks, guys. The best news is that your PARCP-USB units have been shipped this morning. You can expect them in less than a week, hopefully.

Daniel, the idea of Ebay is interesting. Though for the next batch, the last one, I'd need at least six pre-orders before I can go ahead with ordering the components. And I am not sure how Ebay could help me with that. What I may try is to sell the last free items from the current batch there. But I kind of prefer to sell it to guys that I at least virtually know so I can exchange emails with them and help them out eventually. Ebay feels more anonymous in this regard.

I ordered a second one yesterday. They look so awesome in the picture, I thought I had to have a spare.

I just now received my two PARCP-USB devices.

They look great.

Very professional work.

Thank you!

Thank you, I am very glad you like them :)

Wow, so the post can make it in just three days from Czech Rep. to Germany. Thumbs up for them! :)

I'm going to email the registration details immediately, sorry I haven't done so yet.

BTW, I have sent all remaining PARCP-USB adapters yesterday and now my order backlog is empty, first time in two months. And there's one adapter left so if anyone is interested I can ship it immediately.

FYI, I have just released a new version of PARCP - v3.97 and also updated the full documentation regarding the PARCP-USB adapter:
http://joy.sophics.cz/parcp/whatsnew.htm
http://joy.sophics.cz/parcp/parcpdoc.htm#Changes

I have managed to compile the new version even for old DOS so those with PARCP cable can now benefit from the numerous bugfixes that I made while working on the PARCP-USB.

Time to try compiling for the OS X now :) When/if I get something working I'll let you know here.

Today I did my first "quick test" with my new PARCP-USB devices.

It was a matter of plugging everything in and start the software on both sides.

Works like a charm. I am very impressed by the professionality of these devices. Phantastic work, joysfera!



I would like to measure my speeds I can achieve when transferring files.
What´s the best method to do speed measurements, that are comparable to your published speeds?

I am very glad that you're happy with how PARCP-USB looks and also how it works, thank you. The plug&play is an important feature of this USB solution as originally it was kinda complicated to set up the parallel port on a PC for PARCP cable properly.

As for speeds: the numbers published were measured in ideal conditions: files were copied from ramdisk to ramdisk so there were no slow downs caused by harddrives. If you wan to reproduce it then copy one large file that takes at least 20 seconds to transfer because the time is measured to seconds, not fractions of it, so the shorter the transfer time the less correct the number printed by PARCP Server is. And you want to have as large the BlockSize as possible - for Falcon at least 128 (it's in kilobytes).

I usually copied over 2 MB file created in Linux by the following command:

$ dd if=/dev/zero of=/dev/shm/testfile bs=1M count=2048

On slower machines (ST) I made the file shorter and also lowered the BlockSize (I think I used 32 on ST).

Another important thing is to disable the CRC (the control checksum) as it takes a lot of CPU time to compute it so it again slows down the transfer on slow machines.

For Linux you can use the /dev/shm/ path as a ramdisk. For Windows I don't know about any ramdisk but frankly I didn't search for it.
However, I spent good time searching for TOS ramdisk and it's been surprisingly hard to find one. You obviously don't want those that provide on-the-fly compression as that slows down again. At last I found a very simple ramdisk but it seems to be buggy, anyway.

In short, I wouldn't bother with measuring the speed and would just enjoy that it's working fast and fine. You might want to explore the scripting features or drag&drop support instead :)
BTW, do you know that PARCP can set up precise time&date on your Atari? ;-)

I have compiled a standalone demo of PARCP fullscreen interface that I call ParShell (for some historical reasons). I have sent the OSX binary to frank.lukas for testing. If anyone else with a Mac wants to give it a try please mail me and I'll send it to you as well. It might not start at all (probably due to a missing library) but if it did run it should look as follows:

parshell.png

FYI, this is a ParShell.TOS running in my MultiTOS setup in TosWin2 window. I've made this screenshot for Jo Even who has issues running the PARCP under XaAES. My setup is using N.AES. I should try installing some EasyMiNT with XaAES if it indeed behaves differently (I doubt that).

I tried out the PARCP-USB today on my Falcon030 (plain TOS 4.04) connected to a WinXP computer. It worked very well, reaching about 50k/s. I'll try it out on a Win7 computer later to see if I can achieve higher speeds. 50kb/s is still a huge improvement compared to what I achieve using the Ethernet adapter. Thanks a lot of developing this hardware and software!

Regardless of running the server or client software on WinXP I get an exception every time I step up to the drive listing on the Windows computer. Seems like the software scans drives and for some reasons gets into trouble. The dialog's title says "Windows - No disk". See attached image. Any clue on how I can avoid this? It doesn't matter if I have a floppy in the floppy drive or not.

I can confirm that I have also had these kind of error messages. My setup: Windows XP, SP3 and Falcon with TOS 4.04.

Working on the floppy issue but it's hard for me as I don't have any computer with a floppy. Neither my colleagues have them. So I am forced to do blind changes and to send binaries to testers like Daniel. Slow and complicated so bear with me.

This ParShell.TOS application is very nice for the Atari running MiNT ...

I received one of my Parcp-Usb adapters and ran a quick test copying a few files. It works great, very well built, and high quality. :cheers:

Thanks, 499, I'm glad you're happy with it.

dbsys, would you please test http://joy.sophics.cz/tmp/parcpwin.exe if it still suffers from the weird "No Disk" alert when you try to list all the disk drives?
I have sent it to Daniel several times but for some reason he never received it. It's just a ParShell demo, so no need to launch Atari for test, there's no communication.

joysfera, I tested the "parcpwin.exe" and it seems to work OK.

No error message when jumping around between disk drives.

I can however force the error message to come up on purpose by selecting a: which is my floppy drive with no floppy disk inserted. But that´s obviously normal.

The error message will not come when I do anything else inside the PARCP browser.

You know what is very strange?

Now that I tested your parcpwin.exe (which is demo only) once, I seem to be unable to run the full version.

When I try, I see the PARCP window for a fraction of a second, and then it disappears again. PARCP full version does not run any longer. Why?

Try starting the pacp.exe from a command window (Alt+F2 cmd.exe) - there should be a message that explains what's wrong.

And please, if possible email me with such bug reports. I am an email kind of person and can manage (mark, prioritize,...) information in my email box. This forum is handy for chatting with all of you at once but I'd prefer emails for the bug reports.

BTW, Daniel ran the parcpwin demo as well at last but didn't report any issues with running normal PARCP afterwards.

PARCP beta for testers

Postby joysfera » Wed Jan 21, 2015 12:37 pm

Hi,

I thought I'd ask here - if someone has time to test a new version of PARCP before I'll release it into public please e-mail me. I'd like to make a new major release and wish it was as bug free as possible.

Thanks

I received my PARCP last month and stupidly sat on it for a while when I could have been playing with it and saving myself some pain.

I set it up the other day and did some tests. It's awesome. I wish I had it 3 years ago :)

Hi joysfera, how are you getting along with the new PARCP version?

Were you able to get enough feedback from enough beta testers?

I´m just curious....
