  1. Who currently owns the rights to these tutorials? Has anyone secured permission to distribute/archive them? The "Tricky Tutorials" was one of the the very first non-game programs that I purchased. -Larry
  2. " The Atari was absolutely amazing for its time, and it managed to do a good job of holding its own (and sometimes surpassing) the newer machines that came later ... but the genius of its design can only do so much against the march of technology." Well stated! One could make some fairly simple assembler benchmark(s) to measure the processing power. Much of the code should be interchangeable. You could add or subtract the display and other major individual features like disk access to get an idea of the overall processing from a particular machine. OTOH, seems like a whole lot of trouble, plus then you have the issue of "original design" vs "improvements." Many Atari folks would like to ignore the original Atari 8K BASIC, slow floating point, and even slow I/O. But that's what they came with. -Larry
  3. Thanks for you work Allan! It is always great to be able to preserve and share the old magazine programs. Happy New Year! -Larry
  4. I briefly scanned this thread (again) and didn't see anything about using it with an emulator. Could Altirra be revised slightly to accept the keyboard input from a real Atari? That would be wonderful! Retro Pie? MIST? etc. Looks like there could be several retro uses for such a device.
  5. O.P.: It is pretty unlikely that you will ever see an Atari equivalent to the Maxi or even Mini due to the economics (as others have said). I think that the closest you'll come is our Atari FPGA versions (eclaire XL or MIST or MISTer). These are essentially hardware emulators rather than software emulators. And they do a very good job, overall. The 1088XL certainly is a full-featured modern Atari, but you declined the DIY versions. (I certainly understand the reluctance for the most users to take on such a complicated project!) And the price for a "pretty darned close" C64 maxi of less than 150 Euros! Wow! Priced right! And with that you get some very good games! I think they will sell a bunch of them, and continue to fuel the retro boomlet. I don't have a C64 Maxi, but I think it falls a little bit short of providing a full retro experience. But it does have a serious advantage of having a full, cloned C64 keyboard. All of the alternatives that use a PC keyboard are lacking in usability (again, IMO). Our Altirra (PC-based) emulator is a true wonder of emulation, but it still suffers from the keyboard issue. Hopefully we will have the ability at some point to use a real Atari keyboard with the eclaire XL. Part of the retro experience is also using the older peripherals. I'm pretty sure that you cannot use a real 1541 or other C64 retro peripherals with the Maxi. You can use disk images, which is pretty close. Perhaps with the yet to be released MEGA65? AFAIK, the eclaire XL is unique in this respect.
  6. What do you think of the SDrive Max? -Larry
  7. Hi Zen! Yes, it works either way. IIRC, the XL worked that way by moving a jumper inside the case. I don't think that the XE could be used in that way. (?) But as a easy to use ram expansion, these were great! -Larry
  8. Great! Hope you enjoy it for a long, long time! -Larry
  9. Congrats! Now I have my first request... I dropped my ABBUC membership this year because there is little to nothing in English anymore. At one time, the monthly mags were translated to English and we were able to download the translations. I understand that ABBUC lost the resource for translations, but perhaps you could look into getting this going again? Google translations just won't cut it for the typical English-speaker, and even with my 3 years of high school German (50+ years ago), it just doesn't work well. I'm sure it is a drudge to translate stuff, but have you considered paying someone? I'd certainly pay extra on the membership to get stuff that I could understand. "An English Surcharge" Anyhow, food for thought. Thanks, Larry
  10. "But one thing that could work is to just quote everything on a page then block copy it to your Word document. A bit dirty but might be sufficient." That's a good idea! And that way, I can easily edit out OT replies. I didn't know you could do multiple quotes. Had not heard of HTTrack. I'll check that out.
  11. There are several threads here that have some really valuable technical information that I'd like to have handy. I currently (sort of) have them organized by copying the links, and the links are organized by broad topic. Is there a way to copy the entire contents of a thread (and paste into a WP)? I know that I can copy/paste each individual post, but that is a real drag. Any thoughts? -Larry
  12. Neat little project. Just curious -- can Action! executables be put in cartridge format? I don't recall seeing one, but offhand, seems like it should be possible. Anyone know of one that already exists? Do you have a size goal -- 1 to 2K maybe? That would leave room for some other utilities. (?) -Larry
  13. The Black Patch Sector Copier from CSS suggested that a sector copier should write out whatever it read, even if the read was an error sector. It claimed that many more disks having bad sectors could be successfully copied by doing this. (YMMV) The whole idea of the "Black Patch" was make a copy of everything it could, then to re-write/bypass copy protection, similar to the Chipmunk.
  14. Here's what I've found (and at this point 5 years later, I can't say that I understand all that is shown in the docs): Switches 1....2....3 (reading from the label) 1. Down Down Down shows 64K on XRam (64 base + 64) 2. Up Down Down shows 256K on Xram (64 + 256) 3. Down Up Down shows 64K on XRam (64 + 64) 4. Up Up Down shows 512K on XRam (64 + 512) Note that in the above that the remap is set to OFF. Both of the Ram 320XE units show the same results, so I have to believe that they both work exactly as when I got them several years ago. I have not been able to verify some of the remap=ON as mentioned in Ctirad's docs. I have a totally stock 130XE that performs perfectly normally when remap is OFF or when the Ram 320XE is not connected. The issue is the remap=ON setting. If I set the remap to ON, the machine will either display a black screen or stop in the middle of the boot. I have a gut feel this is an NTSC issue. But I have no PAL machines to test. Could someone else in NTSC-land test this. Also, could someone with a PAL machine test it. Here is the easiest-to-understand map of the settings:

    C060609

    Hi- Thanks for the input. The chips I was comparing the 81464 ones were 4464 which are typically mentioned in the 600XL 16k, 2-chip upgrades (to 64k, 2-chip memory).
  16. I am attempting to test the Ram XE units. I can't remember how to read the dip switch diagrams. Does the little white spot on the diagram indicate the position of the dip switch, or the black at the other end? I also can't find an explanation about the "requires modification" note on the batch 2 unit for the 576 kb. Is there another thread I missed?
  17. Check the end of the Ram 320XE/576 order thread.
  18. OK, I've checked my stock of upgrades. I have two of the Ram 320XE. Both say Rev 3. One says batch 2 and the other batch 1. The pcb's are a bit different. Neither have an ECI pass-through. It appears that the screws holding the shells together are under the labels, so no pictures of the pcbs are possible. I'll sell either or both of these. PM an offer if interested. I also have two of the earlier Ram 320XL. This is interesting because you can map the base 16K or 64K in or out. Check the original thread(s). The negative thing about these is that they covered up the PBI, but if one uses an SDrive, etc. no big deal. Same deal, PM an offer if interested. (PayPal, of course.) -Larry
  19. Well, yes, I have a couple of those things. I'll dig them out and take a look at what I've actually got. One is Rev 3 Batch 1 which says "320XE/576." Pretty sure it does not have a Covox in it. A really nice thing about this expansion is that it has a regular vertical cartridge jack (and no soldering). IIRC, the next version has the "pass-through" ECI (which turned out to be vertical) and had the pcb layout for the Covox. I'll check. -Larry
  20. I took the easy route: C64 Forever and Amiga Forever and also (SID) Music Star under Vice II, but I only use them occasionally. SID more than anything. They all work great. The issue that I have with all emulators (no matter how faithful) is the irritating keyboard transposing. Of course for playing games, that's not much of a problem. (And I guess that EclaireXL must be classified as an emulator, so I have that too.) So here is a question -- is the 1088XL an emulator? From my limited knowledge, I'd say not, but it does use a foreign keyboard, and the motherboard is quite different. If we get to the point of having replacement chips (Antic, etc.) from FPGA, will those machines be emulators?

    C060609

    Thanks! Now here's a second part -- can the 81464 be used for the 600XL upgrade? The pinouts look the same. If these are OK, I'll use them on that 600XL expansion.
  22. I'm cleaning off my work table, and ran across an unmarked packet of chips (probably from Best Elec.). It contained 2 each MB81464-10 drams and a C060609. (BTW, the print on the chips is clearly C0, and not CO.) Does anybody recognize what the C060609 is, and what these are used for? It's a 20-pin IC, so that should narrow it down. I must have bought these for some type of upgrade -- 600XL, maybe? Hope they are for the 600XL -- I have a new one that I'd like to upgrade this winter. Thanks, Larry
  23. There is a note about the BXL Toolkit in the Fall 1986 Newsletter (side A) under the New BXL Bugs. https://atariwiki.org/wiki/Wiki.jsp?page=Newsletters If you have an early BXL 1.02, you need one toolkit and if you have a later 1.02 or 1.03, then you need another. (So there were at least two carts and two toolkits). You also need the stock XL/XE OS for them to work correctly as opposed to some patched OS like hi-speed, reverse Basic, etc. which will cause lockup. My original Toolkit was for an Orange 1.02. AFAIK, all orange BXL carts are 1.02. I believe that some early black ones were also 1.02, although most all are 1.03. Of course, these toolkits were for an Atari-style dos. My original manual had a typed label inserted that says "MOVE $570,C4,4" so what you patch (or not) may be determined by what version you have. My original disk (unpatched, I believe) works only with the cart 1.02. It locks up with Black 1.03. My toolkit (patched) for 1.03 works with Panos' 5-in-1. It also works with another Black BXL cart V1.03. This cart also fails with the Toolkit 1.02.
  24. No, not what I meant. The line number that I would need in a new program didn't match the line numbers (or variables) that I had saved. Yes, they could be changed, but then the extra editing required to make things usable, would impede the purpose of having the library. I found that by the time I modified the saved routines, then I would save little time. I would usually just take out a previously written program and see how I did things, then write (almost) from scratch. And perhaps that's just me, but I just didn't find that it was very efficient. USR routines are a different matter -- USR libraries are quite usable in a library (like BASIC Turbocharger, etc.)
