Harry, Ok…let me know what you find. Don
I see what you're getting at but it was mor like this: 0102030405060708… What went to the device was 01030507. The array was declared as a UBYTE array. So it looks like it was skipping entire words. I did try a UWORD array 0x0102,0x0304 etc with the same result. The…
Bob, I haven't yet made any 2.0-related changes to ConMan, as I'm waiting for Commodore to come out with a stable 2.0 release. I still do my development on an Amiga 1000 and although I can test things under 2.0, it isn't stable enough for development work. And I don't…
Harry, BTW…here's what I'm thinking. As a byte array, filling it out with integer values should yield an array as follows: (each number represents one byte) 1234567…etc. But if it were a word (16 bits) array, it'd get filled out like this: 010203040506…etc. (and I seem to recall that's what…
Harry, Let me know what happens…it could be a compiler side-effect or bug. Don
Now that's interesting, but one would think 0x01,0x02 would do the same thing. Sure, I'll try it too:) Tnx again. Harry
2.0 Compat. ConMan
Message #118241
Bill, Slightly off the subject, but have you yet released a 2.0-compatible version of ConMan? I know you were working on it (we talked about it at DevCon), but I haven't seen it anywhere (I don't have access to that "B" network :-). Would it be possible for you to…
Harry, I haven't tried this, but you might…just for "fun": UBYTE databuf[BLOCKSIZE] = { (UBYTE) 1, (UBYTE) 2, … etc. }; or UBYTE databuf[BLOCKSIZE]; register UBYTE i; for (i=0; i < BLOCKSIZE; i++) { databuf[i] = i; } Don
Yep, that works Don UBYTE databuf[BLOCKSIZE] = {1,2,3,4,5….}; doesn't work.
Harry, #define BLOCKSIZE 512 UBYTE databuff[BLOCKSIZE]; SCSIcmd.scsi_Data = (UWORD *) databuff; Don
Thanks. I'll try that. What I found did work properly was to create a second uninitialized UBYTE buff2[512] array and memcpy the UBYTE buf1[512] initialized array to it, then use buff2 to scsidata. Mike Roth said the compiler will put initialized data in a data hunk and the uninitialized data…
Look at your data buffer, and it's declaration. When I was working on my test program, I declared it to be a UBYTE array, and then had to cast it to a UWORD array when assigned to scsi_Data. I'm not sure why CBM built the structure showing the data for…
#SCSI HELP!
Message #117966
I'm having troube with the "scsi.device" which has replaced the "hddisk" device on the 3000. I am trying to use the SCSICmd structure and cannot send more than 256 bytes or else the system hangs with the HD light remaining on. Setting up a data buffer with a byte pattern…
Chris, No, nothing else has been added to it, but it's use has been explained much better in the latest ROM Kernel manual from Commodore (published by Addison Wesley. You'd need the libraries and devices manual. Also look at the section on signals. (BTW…it's 16 bits in a signal that…
Don, I'm looking at Mortimore's "Amiga Programmers Handbook". It covers AmigaDOS 1.2 &c., so it's a bit out of date. However, according to what it says here, there are no signal bits in the SignalSemaphore structure. There is a node substructure, a nestcount, a MinList queue of tasks waiting to…
Chris, Ok…if memory serves me right, there's only 8 user bits in a semaphore available….but if you used 5 of those bits for process identification and the other 3 bits (if 8 is correct) for the nature of the request, that'd allow you to have 32 processes and 8 types…
Ok, sounds good. I'm working on learning about semephores. I like the idea of semiphores better than message ports, because there is an upper limit to the number of message ports a task may have. I don't want my code to interfere with the code that another programmer may want…
Chris, One of two mechanisms… semaphores or messages. Have a master process, the 'brain' if you will. This would be the traffic cop of the system, all database access must ask permission of the master program (via a message or semaphore) and wait for a reply to continue before it…
Yes, you are correct. My indexing system is the good old AVL tree. As many searches as you like can be done at the same time, and you can even add index entries (one at a time) while searching is going on. (Because the addition of the index entry always…
Chris, Having one process do all the work, means you're back to a single user concept…which I presume you want to get away from by having separate tasks. If user 1 is doing a long search and user 2 wants to update a single record and user 3 wants to…
In fact, what I'm doing is setting up an internal queue mechanism, using an EXEC list (or something similar of my own). Essentially, search (and read), add, delete and restructure (rebuild the index) operations will be queued. Add and delete operations will have the highest priority, followed by search and…
I'd set the daemon at a priority of +5 over the other database program(s). My reasoning is that you want an updates, etc. to complete as fast as possible. Otherwise you'll leave your self open for a slowdown and a good possibility of losing data integrity. Figure user A wants…
#CPU Sharing question.
Message #117328
Hello folks, here's a techie question for you… I'm working on building a .library that will allow multiple processes to access a RAM resident database. Any one of these process may add, delete, or search for a record. Because of potential conflicts between these activities, I will be spawning off…
Chris, Back when the Amiga was in the "black box" stage development for it was done on Sages and Suns. -sja
Don't know! ……Betty
Wasn't the really *really* early work done on a Sage? I used to sell Sage systems. (Well, I never actually got anyone to buy one! 😉 ) Chris -)—–
I have em too:)
Thanks!
Message #114765
Thanks to everyone who gave me the info about those disks. Steve
Steve, MS-DOS. You could do development on an XT or AT and then download the code to an A1000. There is also a file transfer program on the disk. I've got the notes around here somewhere on how to use it. The original OS development was done on a Sun…
Steve, have you tried them on MS-DOS? I think there was a cross-development tool for that, too. ……Betty
Steve, I've got 3 or 4 sets of those — the original developers got them.
The original Amiga developer's package included a cross compiler that ran on the IBM PC. Those are IBM disks, of a very early version of the Lattice C compiler. I don't think they've ever updated it. By the way, Manx makes cross compilers, too, but they've never released a PC…
What the heck…..??
Message #114562
I had the wildest surprise today. When my wife got home yesterday, she said that someone where she works had given here some Amiga disks for me. I expected a bunch of 3.5 disks. I now have about ten original Amiga 5.25 floppy disks with labels like "Lattice 'C' cross…
Mike, Great!! That's much better than having to wait for a coupon, then send that in and waiti again for it to be sent out to you. 🙂 Dave Commodore Online Relations

Message #114328
FYI, I called CATS Orders again, and the person I talked to this time said no coupon would be sent, that they would just send the new version of AmigaVision when it is ready. This makes more sense to me since they know who ordered directly from Commodore anyway. Mike
Mike, You're quite welcome! Dave Commodore Online Relations
Mark, Send a copy of your invoice to: Commodore Business Machines, Inc. Attn: Dave Minnich 1200 Wilson Drive West Chester, Pa. 19380 I will see to it that you get a coupon. Dave Commodore Online Relations
I received the machine around July 6. I called CATS orders, and they said they would be mailing me the coupon, and that I should get it a week or so after receiving the computer. Thanks for the help. Mike.
I ordered and received my A3000 from CBM also, and did not receive a coupon also. If I send you a copy of my invoice, will you send me it too. Thanks.
Mike, When did you buy the machine? (what date) If you don't find the coupon, send me a photocopy of the reciept and I'll send you the coupon. Commodore Business Machines, Inc. Attn: Dave Minnich 1200 Wilson Drive West Chester, Pa. 19380 Dave Commodore Online Relations

I have no dealer. I bought the machine through from CBM through the developer support program. I will search again, but I don't think there was a coupon in the box. Thanks, Mike.

AmigaVision
Message #112475
I looked pretty close, but I'll look again. Thanks, Mike.
Actually, I'm NOT using the 030 system, and I'm working off of a boot floppy and I've had it working before under an earlier beta 2.0. It's just with this particular kickfile version that I've started having trouble. I may indeed need to reformat my disk. I hope not. It…
The methos I described is the only way to have dual operating systems on a 2000. The 3000 has 2.0beta3 Roms that support the dual boot feature. -Greg
I got mine setup by just copying the 2.0 Workbench and Extras disks to my non-primary partition, already set up ffs. I put the Kick.38n.20 file on my DH0: partition and created a script file to execute Kickit (which I copied to DH0:c from the Kickfile disk.). I created an…
Have you tried calling GVP? Also, did you read the 'readme' files on the Kickstart disk? I read through them and was confounded at the complexity of trying to make a dual-boot system… I have a GVP '030 on loan, plus a separate Impact controller with 2 megs and autoboot,…
Kick.38n.20 and GVP
Message #110798
Has anyone else out there had trouble getting kick.38n.20 (the one released at the DevCon…) running with a GVP Impact hard disk controller? (NOT the 030' card, mind you…) The older kickfile (32e) works just fine, but the new one causes a system error as soon as Binddrivers is executed…
Installing 1.4 B5
Message #109340
Just rearranged my Supra memory card and Pacific Peripherals Overdrive controller (on the card, it says, "Interactive Video Systems", or some such…) so I could run 1.4 B5… however, when I boot, I get a guru 80000004. I'm using the 1.3/1.4 s-s as a template. I think I get the…
SetPointer() and Gadgets
Message #109117
In the program I'm currently working on, I noticed something. I call SetPointer() every time I detect a GADGETUP or GADGETDOWN message, to flip between two pointer images. I noticed that _on_the_first_gadget_in_the_window_ONLY_ it doesn't make the change. Have a stumbled onto a bug? Or, what could cause this? –Eet–
