Shaun.Bebbington Posted February 17, 2008 Author Share Posted February 17, 2008 One thing that I find is just a general understanding between what upgrades I need and don't need. On the Commodore, it's pretty simple, but then I would say that as I've used Commodore 8-bits for many years. Atari fans may have trouble with Commodore's DOS wedge commands, for instance. On the C64/128, all good storage solutions are compatible to a certain extent with the 1541, so if I want to load games or programs quickly, there's a good chance that they'll work with somethink like a RAMLink or an FD2000 for instance, and transferring files from MS-Dos disks is pretty simple if a little slow. You get into other formats is a bit of a mine field; for instance, there are many types of mass storage solutions for the ZX Spectrum, but which one do I need, and which is the most compatible with the existing software base? Do they work with all revisions of the Speccy, or just the rubber-keyed models? I know that I can replace the 3" disk drive on the Speccy +3 with a 3.5" drive, but is this really worth doing, or is there a better solution? I have a disk drive and other devices for my Atari 8-bit, but how do I transfer disk images to it? And is it worth doing with my Atari 800 when I want to play the latest games rather than classic games? I'm not completely dumb when it comes to computing, but if the available upgrades are in any way quirky or require me to learn a whole new way of doing things, then I simply don't have the time. Mostly, all that I want to know is how to load software. Regards, Shaun. Quote Link to comment Share on other sites More sharing options...
+Philsan Posted February 17, 2008 Share Posted February 17, 2008 Regarding storage devices, Atari computer are without any doubt way better then Commodore or Spectrum ones. We have SIO2PC (now also USB version), that trasforms the PC (also with Vista) into a virtual disk drive and a printer. With SIO2SD you can insert disk images or executables in a SD card. This 2 devices are very cheap: around $50. Quote Link to comment Share on other sites More sharing options...

With SIO2SD you can insert disk images or executables in a SD card. This 2 devices are very cheap: around $50. I doubt that you can say storage solutions are better on Atari 8-bit. My Commodore 128D consists of a SuperCPU (runs C64 and 128 mode at 20Mhz + 16Mb of system RAM, switchable to 1/2Mhz mode for compatibility), CMD HD (2Gb hard drive with CD-Rom and Iomega ZIP drive attached), various networking carts (RR-Net and Turbo232), FD2000 (1.6Mb floppy disk, reads and writes to MS-DOS style disks), and 16Mb RAMLink (solid state RAM disk from fast loading times). The only "better" thing would be cost - CMD devices are very expensive. I also have an IDE interface and know of other solutions that allow you to turn any old PC into a virtual hard drive or disk drive. So, we're at least on an equal footing. Is there an accelerator upgrade from the Atari which also gives it more RAM anywhere? And what is the weblink to the SIO2SD? Regards, Shaun.

+Philsan Posted February 17, 2008 Share Posted February 17, 2008 (edited) Yes, I am talking about cheap and popular storage devices for the masses. C64 has MMC64 (loads only executables not disk images) and 64HDD (not very user-friendly); I have these 2 Commodore devices. You have written: "but if the available upgrades are in any way quirky or require me to learn a whole new way of doing things, then I simply don't have the time. Mostly, all that I want to know is how to load software." I am exactly talking about simple storage device for Atari; there's nothing simpler then a usb interface like SIO2PC or an SD card reader/writer like SIO2SD.

+CharlieChaplin Posted February 18, 2008 Share Posted February 18, 2008 (edited) Ok, Heaven asked me to upload the Turbo Tape programs, well here they are... TURTAP1.ATR contains some programs that allow one to use a turbo tape via software, e.g. the programs FMOVE.COM can produce tapes with 800 Baud, Speedtap.Bas can produce tapes with 1000 Baud and Cbaudcop.Bas can produce tapes with 1200 Baud (use Cbaudloa.COM to load the 1200 Baud tapes). All programs with extender .CAS were transfered with a 1010 tape recorder to diskette without any conversion (one may load them with a C-Simulator or copy them back to cassette again)... these CAS files are NOT the same as the ones produced on the PC with WAV2CAS... TURTAP2x.ATR contains programs and schematics for the german turbo 6000 interface (a hardware enhancement that has to be built-in into the Atari tape recorder; it will use up to 6000 Baud then)... no warranties, no guarantees or whatsoever, I have never used such a tape drive nor its software... TURTAP3x.ATR contains programs and schematics for the polish or czech turbo-2000 interface (again a hardware enhancement that has to be built-in into the Atari tape recorder; it uses variable Baud rates afaik)... and again, no warranties, no guarantees or whatsoever, I have never built nor used such an enhancement... This is just what I have in my collection - there are many more turbo tape programs out there... -Andreas Koch.

carmel_andrews Posted February 19, 2008 Share Posted February 19, 2008 (edited) CC/AK...Is the 'Turbo Tape' hardware the same/similar to the one Rambit/Microdiscount did way back when (i've got a feeling it is) If memory serves me right an eastern european company called bewesoft (of BW dos fame, a spartadros alike dos) did a spartadros compatible program that allowed copying of binary files (incl. appended compressed ones) to 'turbo tape' format and it added a loader as well...i think the program was on one of the TWAUG disk mags and it was called BW Tape Edited February 19, 2008 by carmel_andrews Quote Link to comment Share on other sites More sharing options...
Shaun.Bebbington Posted February 19, 2008 Author Share Posted February 19, 2008 Hi Heaven, If the 1200 baud loader works with unmodified Atari hardware, then that's great!

+CharlieChaplin Posted February 19, 2008 Share Posted February 19, 2008 Yes, CBAUD works with unmodified hardware. All you need is the "converter" program (CBaudcop.BAS) that transfers file programs into 1200 Baud (may work with tape as source and target only, e.g. load with 600 baud from tape, then save with 1200 baud to tape; not sure if a program can also be loaded from disk and then saved to tape)... as mentioned before, the converter is written in Atari Basic and thus limited to 32kbytes (37k with compiled Basic / TB XL), but maybe somebody out there can write a similar converter in ML that has more memory available... afaik, CBAUD alters the OS, maybe it is possible to even switch off the OS and then use up to 56-60kbytes as a buffer with a new ML converter... Again: To load the 1200 Baud tape you need a special loader program called CBAUDLOA.COM (or CBAUDLOA.CAS which is the cassette version one has to transfer to tape first)... I must say, that I never tried this CBAUD program, because I did not like it that I had to use a special loader program to load the "faster" tapes... As said before, Fmove.COM (800 Baud) and Speedtap.BAS (1000 Baud) work without a special loader. You only have to copy the tape program into the faster format and then load it as you normally would, e.g. with START or START+OPTION... I guess one needs to produce boot tapes - if you only copy the *.COM/*.XEX/*.OBX... ML file to tape, then one would also need a ML loader for cassette to load this ML program (on disk this is done by a DOS or GameDOS; on tape one can use ML loaders like COS or my ancient favourite BL/C; where COS means cassette operating system and BLC means binary load cassette)... but I am not sure here... I merely used Fmove.COM once to load a standard (unprotected 600 Baud) boot-tape and saved it as a faster (800 Baud) boot tape and it worked - I am not absolutely sure if and how the other programs work... so, you are on your own !! --------------- Errm, the turbo-tape 6000 (from eastern germany) is not the same as the turbo-2000 (from poland or czech rep.) nor the same as rambit turbo-tape (from the UK). These three are different hardware enhancements for tape-recorders, they were used+produced in different countries and *afaik* they are *not compatible* to each other... but since I never used a hardware turbo-tape I might be wrong here... greetings, Andreas Koch.

TMR Posted February 20, 2008 Share Posted February 20, 2008 Jason, what about using this 1200 baud loader for Reaxion? Well, because nobody said anything about these loaders the last couple of times we asked, we already have a tape image - just no loading music... Sack's doing the mastering (on those rare occasions he gets time) so if you want to persuade anyone to rip out what has already been done, he'd be the bunny to talk to. =-) Quote Link to comment Share on other sites More sharing options...
pps Posted February 20, 2008 Share Posted February 20, 2008 For converting a programme to 1200 baud you can use "The Happy Turtle". If you load it from a dos you´re also be able to load from disc and save to tape. The needed loader has 15 counts on XC12 and can be saved by Happy Turtle as well.

+CharlieChaplin Posted February 21, 2008 Share Posted February 21, 2008 Hmm well, but how does "The Happy Turtle" work ?!? Binary loaded it from DOS (with Basic disabled) and got a title screen, but that was all. Pressed keys Start, Select, Option and nothing happened. Pressed Return key and nothing happened. Pressed fire button / joystick trigger and nothing happened... so I gave up... PPS do you know how to use or operate The Happy Turtle (and which keys or key-combinations must be pressed) ?!? Besides, the title screen of The Happy Turtle also mentions another program called Turbo Copy 1500 or something. Do you have that program and can you upload it here ?!? greetings, Andreas Koch. P.S.: I am talking of The Happy Turtle program I have in my collection and uploaded here with others as Turbotap1.ATR - hopefully you mean the same program...

carmel_andrews Posted February 22, 2008 Share Posted February 22, 2008 (edited) From what i remember about 'software based' hi speed loaders (on unmodded cassette decks/drives) is that anything over the standard 600baud, the loading reliability starts dropping of alarmingly I'm not too sure that similar tests have ever been carried out on hi speed modded cassette decks/drives (hopefully the loading reliability is somewhat improved) Edited February 22, 2008 by carmel_andrews Quote Link to comment Share on other sites More sharing options...
Rybags Posted February 22, 2008 Share Posted February 22, 2008 I can't remember the exact figure, but I settled on something around 800 when I made a turbo-load system. You actually gain a lot too by using larger block sizes. Imagine eliminating the .25 second IRG on a 16K file - that alone would equate to 48 seconds reduced loading time.

Heaven/TQA Posted February 22, 2008 Share Posted February 22, 2008 can not be any of the C64 turbo tape systems being adapted? I mean that tape is serial as well and ours, too...or are there any other differences? Quote Link to comment Share on other sites More sharing options...
Rybags Posted February 22, 2008 Share Posted February 22, 2008 Too many differences, I think. The problem is that the 1010 has internal circuitry that interprets the frequencies it "hears" on the data track, and outputs a 0 or 1 to the SIO bus. Wheras many other systems cassette interface is a more direct thing, so on the C-64 you have more direct control of what's happening. I'd guess that all of the hardware mods for Atari drives just up the ante - use higher frequencies for the FSK tones which allows shorter interval between bits, with the demodulation circuitry adjusted to be able to read them.

Heaven/TQA Posted February 22, 2008 Share Posted February 22, 2008 so actually Baud 1200 plus 1 block instead of 125 byte blocks is relyable enough? Quote Link to comment Share on other sites More sharing options...
Rybags Posted February 22, 2008 Share Posted February 22, 2008 The default C-64 tape handler actually saves the data twice IIRC correctly. The Atari method was probably chosen as it was because it is friendly toward programs which want to read and process data simultaneously. ie - the long IRG mode allows stopping indefinately. Also, due to the way CIO likes to operate, data is buffered before being moved to the user's data area. Really, they might have been a bit better off by allowing variable blocksizes in the C: handler. To get long blocksizes, you have to make direct SIO calls - a bit of extra work, but worth it so far as extra speed. Also, it gives you copy protection for free as a side-effect.
