  1. 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
  2. What verson of APE are you using? Did you run the APE Configuration Wizard? What did it say? -Larry
  3. "Rare" lies in the eye of the seller. (especially in auctions... ) -Larry
  4. 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
  5. 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
  6. 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
  7. Got it! I checked the wiring one against the other and no differences, but I gave each of the connections a "tug" test and one popped off way too easily. Re-soldered it, and all is well with the ramdisk. I'm still not sure how it passed the ram test, but can only assume I had an "intermittent" connection. -Larry
  8. 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
  9. 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
  10. 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
  11. 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
  12. 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
  13. 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
  14. 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
  15. > Nir does some awsome stuff with 8-bits. I got one of these from him a couple years ago. It works fine. < Have you used the "Freezer" function and if so, how effective is it? Thanks.
  16. The SIO2IDE is a neat interface, but I'm having a problem understanding what its benefits are versus a native Atari HD such as MyIDE. And it would have to be much slower. What am I not recognizing?
  17. Hi- Yes, I saw the Turbo-816 demonstrated at a user group meeting. At that time I believe the OS was just patched, and the only difference I could tell was that SIO sound was slightly faster (but not even close to a track-buffered Happy Drive at regular speed). I was very unimpressed, but in retrospect, that probably was a mistake. We did get to look at it, but I have no pictures -- and it's going on 20 years ago, so I don't recall any specifics. I regret not buying one, but if the new Polish version is released, I won't make that mistake again. -Larry
  18. Has anyone ever looked at how closely these two roms were coded? The units are essentially identical except for the difference in ram. Thanks. -Larry
  19. > The MyIDE (original external cart version with 3.1 drivers) is a dog by comparison: DOS writing: 2806.680942 B/sek. DOS reading: 2849.391304 B/sek. DOS average: 2828.036123 B/sek. < Here are some recent figures for the MyIDE flashcart V3.5f used with a compactflash card: Dos Writing 11988 Dos Reading 9781 Dos Average 10885 Quite a bit improved from the earlier figures posted here. I suspect that these figures can be influenced quite a bit by how full/fragmented the HD is. For the best measurement of the interface's potential, you'd want to use an essentially blank HD. Incidently, in the tests that I've run with the KMK/JZ interface, there is very little difference between compactflash and HD figures -- at least on "empty" drives/cards.
  20. > ...and Ive got a freakin STACK of old SCSI hardisks that will work perfectly with it. < Interesting. What SCSI hard drives do you have that will accept 256-byte sectors? Or have you "reprogrammed" the drives internal code to allow 256-byte sectors with something like "Bart's SCSI Tool?" I ask because I've only found one SCSI drive that allowed formatting with "small" sectors a Seagate 225N. MFM with a bridge-board (the latter now really hard to find), no problem.
  21. > Im building brand new MIOs... < Very interesting. Still 256-byte sectors, SCSI? -Larry
  22. I decided to re-run the Black Box RWTEST using my IDE laptop drive with the IDE/SCSI converter. For whatever reasons, it came out better than with my previous Conner 3-1/2" drive. New values: Dos writing 11045 Dos reading 20587 Dos average 15816 This was with MyDos 4.50 -- same as original test. I repeated this several times, and the numbers were quite consistent. The previous numbers for comparison were Dos Writing 7110.5967 Dos Reading 20373.8859 Dos Average 13742.2413 So the writing improved by more about 55%. That's quite an improvement -- any thoughts as to why? -Larry
  23. Interesting question! Presumably you have already cleaned the R/W head. (?) After extended service, the R/W "felt" pressure pad can also clog with oxide and compress, causing problems. Also, early 810's had poor data separation ability, and to a lesser extent, speed control. A later modification added a data separation board -- called the "Grass Valley" modification, IIRC. It's also certainly possible that your 810 has alignment issues after all these years. If you check at Best Electronics and B&C Computer Visions, they still carry quite a few 810 parts/assemblies. B&C also does repairs. Later drives like the 1050 and especially the XF551 had much better data separation capabilities. My XF551 will read disks that no others in my collection will touch. This isn't just one thing -- the electronics are better; the mechanisms are better; as with most technology, newer is (usually) better. -Larry
  24. > No, the opening and closing the file does not count. ... < OK. I certainly would not have expected SDX to be that much faster than MyDos, but there it is. BTW, I did find the MIO HD benchmark figures. I re-tested the Black Box using SDX, and as expected, the benchmarks improved quite a bit, although still not as fast as with KMK-JZ. Dos Writing: 8436.12 Dos Reading 26568.65 Dos Ave. 17503.38 -Larry
  25. I just made an interesting discovery. I wondered about the difference between my KMK-JZ interface RWTEST speeds and those posted by Drac030. The only thing that seemed logical was that the benchmark figures varied quite a bit from the Dos overhead for RW. Sure enough, I re-ran the tests on the hard drive using my SDX cart with quite different results: Dos Writing 11331.87 Dos Reading 38560.59 Dos Ave. 24941.23 Long story short, apples to apples comparisons will need to be SDX or MyDos specific. I suspect (but don't know) that the file opening and closing is a major component of the difference. -Larry
