  1. > maybe it is me, but is it quite difficult to use maxflash spftware with perl... <

     

    You might want to post this in the AtariMax Flash Forum. Yes, I know several people who have the same issue, including me. Steve has said that he is going to make a "quick start guide," to use "MakeMenu," but I don't think he has had time yet. MakeMenu supposedly simplifies stuff. -Larry


  2. I have a bunch of Page 6/New Atari User magazine disks (the "cover disks"). Unfortunately, years ago I transferred the files (or DCM images for non-dos disks) from each disk side to 720K DD MyDos disks, placing the files from each issue in a separate subdirectory/folder. Saved lots of space, but now I'd like to resurrect these disks as regular ATR images, including the Dos 2/2.5 system files. There's the rub. I can copy the files to new 90K ATR's easily, but then rebooting with Dos 2.5 to write the new system files, then back to MyDos over and over is a time-consuming pita. Does anyone have a better solution? I vaguely remember that there is a way to copy DOS.SYS as a file and still make the disk bootable. (?) Thanks!

  3. DScaler has yet another virtue -- it it the only way that I have found to get 24 full lines X 80 columns of the XEP-80 correctly displayed on a modern PC monitor using Win TV (PCI). I tried *lots* of hardware trying to get the XEP's overscan under control, and this was the *only* thing that worked. -Larry


  4. This COMPUTE! Article from Bill Wilkinson is mentioning an OSS PicoDOS. Maybe a kind of GameDOS. But maybe more. Does anyone know where to get this, or where to find additional information?

    Which article -- presume it was an INSIGHT Atari, but which?

     

    Without additional reference on the article, I can only speculate -- OSS supplied a very small dos with their BASIC XL and BASIC XE toolkit/extension disks. This dos did not even have a DUP.SYS package. It allowed running their menus via AUTORUN.SYS and LOADing/SAVEing programs.

  5. Does anyone out there have MyDos 3.13b? 3.13b is the version of MyDos that contained the drivers to allow using a HD with the ATR8000. IIRC, in order to use a HD with the ATR8000, one must set up the HD for CPM (and have the ATR interface board, naturally). Then one of the partitions is set up for the Atari, and then 3.13 can look at the drive and find the Atari partition. IIRC, I have the utilities to set up the drive, but no 3.13b :-( -Larry


  6. It didn't take long at all :) He inquired about my odd serial port information (IRQ 19?) and strange base address....adjusted the program and sent me a new upgrade file. I just played half a dozen games and am extremely happy :) Too bad I have to go to work in the morning!

     

    Glad you have APE working now. :) Registered APE is *the* most useful Atari software available (IMO). I ran an SIIG serial card for about a year, and now that I think about it, I remember there were some problems getting it going initially. I think that ultimately, I switched the devices so that APE was using the motherboard serial port, and my external modem used the SIIG. It had no trouble with the SIIG settings. -Larry

    Larry:

    Hi,

    sorry ATR2MyIDE can't copy partitions from one CF to another, but could be an interesting features to future.... try Norton ghost.

     

    cheers to both

     

    Hi Nachocientos-

    I'll probably have to wait and hope that you can add this feature at a later date. All of the PC backup utilities must find the FAT16 or 32 to operate, at least in a USB adapter. I'm going to try this directly in a PCMCIA Adapter, but I'm not hopeful. I've looked hard for a true "sector copier" but so far have found none. -Larry


  8. Hi Nachocientos-

     

    Can your ATR2MyIDE utility be used to copy an entire partition from one flash card to another?

    For instance, if I have two compact flash cards with partitions of the same size. (All my

    partitions are *always* 60,000 256-byte sectors.) It takes about an two hours to copy a complete

    partition from one card to another using APE as the intermediary. Using a PC could do it in a few minutes!

    Thanks. -Larry


  9. Hi Ken-

     

    >Yeah I also suggest SatanTronic's X-RAM test program because it will show you the actual staic condition of just about any bank of extended ram that could possibly be hooked to a PIA register. It even supports upgrades up to 2 megs if Im not mistaken.<

     

    Thanks! I had not heard of the X-RAM program. I'll check it out.

    -Larry


  10. I just finished this upgrade in an XE; the second one I've done. The first was many years ago, so I don't remember much about it. This upgrade passes the Newell memory test program, but things still don't appear quite right. The problem is the ramdisk. If the ramdisk gets close to being full, MyDos 4.50 writes over the ramdisk directory. I've tried both the XE and Newell page sequences with similar results. Does anyone have any additional info or programs that could help me diagnose this probelm? Thanks. -Larry


  11. Here are my current compatability findings with both the original ICD MIO, and the new MIO board:

     

    I do have an ST225N drive, and the new MIO boards work 100% with this drive, using the original ICD ROM.

     

    I also have an ST157N which works great, until power is removed from the drive, itself. Both the ATARI and MIO can be powered down, and I can boot from it, but when the drive, itself powers down, and back up, it cant seem to "figure out" how to get back into the correct mode to communicate with the MIO. It can read the configuration sector, but thats about it. If I reformat the drive, and copy everything back to it, it will work again, until the drive itself is powered down again. Strange, eh? This ST157N (I believe) was made in 1991, so its a bit newer than the ST225N.

     

    I also have an ST138N which behaves similarly, but I believe this drive to have quite a few bad sectors on it, and its not really a reliable test drive.

     

    I dont have any old SCSI-MFM controller boards to test, but Steve Carden will be testing one (Adaptec 4000A, I believe) with the new board, within a week or so..

     

    What I would like to see for the "fixed" version, is compatability with at least 80-90% of SCSI-1 and SCSI-2 drives. This would put it on the par with the black-box, compatability-wise.

     

    Hi Ken-

    I had exactly the same experience with the 157N, which was my first ST drive. It formatted with MIO software, and all looked well, but when I tried to re-boot after power-down -- no joy. You are certainly to be commended for going the "extra mile" to improve the drive compatability of the MIO's! -Larry


  12. I also have a question for MIO owners along similar lines.

     

    From what you've all said, the original recommended configuration for MIO hard drives seems to have been a SCSI-to-MFM bridge (like the Adaptec 4000) combined with one or more MFM drives. That original hardware is getting very hard to find nowadays (I've got a few MFM drives but have never seen a bridge board for sale on eBay or anywhere else), and it would be great if a similar solution could be found for IDE drives.

     

    Has anyone with an MIO ever attempted to use a more modern SCSI-to-IDE bridge board like this one?

     

    I use an IDE -> SCSI adapter similar to that one with the BB. I tried it, and it does *not* work with my MIO. Nevertheless, these are handy adapters since they allow the use of laptop and smaller IDE drives instead of "big" SCSI 3-1/2" drives. I have only found *one* SCSI laptop drive, and it has an unusual drive connector on it designed for a specific notebook interconnect. If the MIO can be revised to R/W 512-byte sectors then this type adapter *should* work with it, also. -Larry


  13. FWIW- I had a good ST296N and it would not format out in 256-byte sectors with either of my 256KB MIO's (at least not with any of the MIO formatters). Someone else told me years ago that it would do 256-byte sectors, but the one I had definitely would not. -Larry

     

    Well, the original formatter programs were pretty limeted. If you look in the MIO manual, it states that for a fee, ICD would write custom formatters for you..

     

    The original MIO utility disk shipped with a program called HDFMTPH, which to my knowledge had very limeted support for sea-crate embedded drives (specifically the ST225N ONLY)..

     

    Later, 2 more versions were released, HDFMTPH6 and HDFMTPH9.. These had support for different/later versions of Sea-crate's embedded controller firmware.

     

    The HDFMTMIO program supplied with REALDOS appears to be based on HDFMTPH9.. (Steve Carden could tell you more about it).. But I have had some level of success formatting and using other sea-crate drives, which I know for a fact will not even format with the original HDFMTPH program..

     

    I don't have an ST296N to test, but I suspect it to be one of these drives, based on the data available from Seagate, and in comparisson to the data available on the ST-225N.

     

    As I said, FWIW. But I tried all the MIO Formatters that you mentioned about two years ago. Even some 225N's cannot be formatted to 256-byte sectors, according to Seagate's tech dept. Some can; some can't based on their firmware revision(s). I never had the inclination to try revising the low-level code. Years ago (90's), I did a pretty thorough job of investigating what could/couldn't be formatted to 256-byte sectors. So, if I were going to *purchase* an embedded drive to use with an MIO, I would be prudent about return policies, etc. if spending very much money. Hopefully, folks already have or can easily find drives that will work fine. -Larry

    Ok. Heres a list of drives that I BELIEVE might work "as is" with the original ROM.

    You guys might want to start looking for them. There are many companies on the web that sell

    them either rebuilt, or used for rediculous prices..

     

    Also, theres some dude named "BRICKCOLLECTOR" on Ebay who seems to stock alot of them.

    (its actually a reputable used/tested hardware reseller, as far as I can tell) His prices arent too bad.

     

    Ok.. For SURE.. The seagate (henceforth referred to as SEA-CRATE) ST225N will work.. It is a 5.25", half-height drive.

     

    Here is a list of drives from the exact same generation of embedded controller design from Seagate.. They are all also

    whopping-assed 5.25" footprint, half-height drives:

     

    ST251N

    ST277N

    ST296N

     

    Ok.. Now.. in case you havent figured it out yet, the last 2 digits in the model number are the unformatted capacity.

     

    Here are 2 drives that I THINK MIGHT work, as I have have some luck with them, but not 100%.. They are 3.5" footprint, half-height:

     

    ST138N

    ST157N

     

    Good news is that alot of these old sea-crate drives were used in macintosh machines.. And we all know that apple sold an assload of early macs.

    So they are probably out there sitting in your buddy's closet, or junk-parts pile somewhere..

     

    Geeze, I hope this actually helps.. Maybe someone with a real MIO can verify the validity of this crap..

     

    Everyone should do what they can to brown-nose steve (money works really good) into fixing that ROM ASAP.. hahah..


  15. Does anyone have or know of any source code examples of Mac 65 code using the OSS Mac 65 Toolkit? The TK does come with one example -- a very simple file copy program. But if I had a few more to look at, it would be very helpful. I haven't had this toolkit out in years, and unfortunately, what examples and programs I did have in the 80's are long since misplaced. Thanks, Larry


  16. Hi Rob-

    I don't use my MIO's much anymore, but I have several Seagate MFM drives, including two (dare I say rare?) 3-1/2" MFM's that I use. I always use an Adaptec 4000-series bridge board with the setup. Works fine, but takes up significant space. If anyone ever re-codes the MIO ROM, 512-byte sectors would be very nice, and would give the MIO a new "lease on life" IMO. My primary system is the Black Box, using an IDE-SCSI adapter with a 2-1/2" laptop drive. Personal opinion -- the usefulness of the MIO ramdisk is limited when the MIO is compared to smaller, faster HD systems. -Larry
