I have this sun spark station 1 at work I save from recycle I never ever used it. Still to this day. Yea it has a sparc processor and everything. I could load I think bsd on it. I used bsd before on a regular x86 machine. But, it is what is the point. Then again I have been doing this stuffs since mid 91. My current project is slackware 8 on a dual PIII running netatalk.
I do have a grease weasel, to produce disks for vintage computers. Most floppy controllers for the PC are unable to produce an FM (Single-density) disk, so the weasel is my go-to in those cases. Prior to getting weasel I was using a PC and various vintage tools to produce vintage disks from images so long as they were double-density. You are right. Were this a vital disk, my first step after cleaning it would be to image it a few times using the flux reader, THEN try file-level recovery.
@@Technoid_Mutant I've only really used mine to image some cross format 3.5" disks from a magazine here in the UK that I thought were interesting. I was always fascinated as a kid how they made disks that could be read on a PC (IBM compatible as they were called at the time), Atari ST and Amiga as a native format on each one with different content.
20 Years ago. More now. I did the same thing. Remove from sleeve. Clean crapola off of it. Cross fingers. Copied data once to hard drive. That was it. Show is over. Got the files. Disk never read again.
0:40 Speed to make a Commodore user jealous. ;p 4:52 I've had problems with using rubber bands as drive belts. They're too soft, so there tends to be lots of flutter in the speed.
Interesting! I have a Sun Blade 100 at home with a broken ID PROM. I've had replacement parts for it for years, but I was never able to implement a fix that would stick. What were your steps in fixing the NVRAM on the IDPROM?
If you just like the old machines that is cool but I am curious, what would you use it for? I ask this because I have a load of old computers ( I used to repair them and people would give me their old ones). I know of some things you can use them for that modern computers seemed to have abandoned. Sending a Fax with a fax card, reading 360k, 1.2, 720K or 1.4mb disks. Run old operating systems natively and the software that requires those old OS. VM machines don't always cut it, especially with games. I would love to hear any other examples of things you can only do with these old machines.
@@michaelterry1000 Honestly, I'm just autistic and enjoy old/obscure machines doing era-appropreate stuff, Or even run Modern stuff, like some form of Linux. Most of my machiens are either used as servers, or toys for OS-es (For example, my Dell Optiplex I got is what I used to dip my toes in the waters of Hackintoshing.)
I had one of these drives with a TRS-80 Model 100. I hardly used it, then tore it apart to see how it worked. I was a dumb spoiled kid. The barcode wand got a tiny bit more use. Figured out how to plot 3of9 barcode on a pen plotter and read it with the wand.
I may just go ahead and put a BSD on my Sun Blade 100. I fixed the NVRAM and reprogrammed the IDPROM (but this sun4u is different to earlier ones like the Ultra30/60, Ultra2, etc. so I had to scare up some info on how to fix IDPROM... was years ago now!) I tried installing Debian 12 on it, and yep, systemd strikes again. Last I had it booting, it would try to boot up, but something in systemd was rotten, so it fell over. Today, it doesn't even have valid boot blocks. :o(
I've not had good luck with Linux on this machine, nor on my Alphastation XP900, nor on my HP9000 D230. You might get it installed headless (no xwindows), but OpenBSD has always been my Go-to OS for vintage machines. They maintain machines for a much longer time than other distros (NetBSD and FreeBSD for example). Both of those latter work, but not with the graphics hardware on the machines. On the PA/Risc box, Linux just doesn't install.
The only disks I ever used that could be ‘flipped over’, were the 3” ones used in the Amstrad CPC6128. It’s true that a 5.25” floppy disk could be turned over on a single sided drive that only read one side but it was far too much hassle and the disk was likely to fail at some point. Personal experience. Running a disk without its jacket is a disaster waiting to happen. The cookie just isn’t designed to operate like that.
Did you even try running Jumpman to see if it wasn't just copy protected there and might actually _need_ that error sector in order to verify the copy protection? Maybe instead of using a copier that does each item as separate files, try using an image copier: one that just copies a disk exactly, sector by sector/bit by bit, regardless of errors, etc.?
Military reference. for example my favorite MRE candy bar was "Bar, Candy, Type 1, Style 3...... It was like a Scor bar but with toffee already in bits.
@@Technoid_Mutant: Maybe what you said in this second reply could make sense as some kind of military reference of sorts, but "brown in color" doesn't. You totally missed my questions about what a color word like "brown" could possibly refer to besides exactly that: a color." "Brown in color" doesn't make sense, because it's a redundancy.
Why would you rasor the disk's --"envelope"-- _jacket_ to remove the disk when you can do more easily by simply snapping the edge-folds off from the main surface?
The jacket is so atrophied with time that flexing it would be to shatter it. I've discovered that feature of old jackets the hard way. Even so, you can see that the razor made a jagged cut.
OMG . . . its amazing . . . I remember that we had an old ATARI 800XL at home (long time ago), and I would never have dreamed that someone would still work with it today. . . I admire you
Its just simple animation runing from the expanded memory. No real raytracing there and visually nothing special. If you want some real 3D calculation, on the fly without precalc check out these Atari demos: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-mNqeUzvhRiw.html ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-9WEp5Yv5Lso.html
Thanks! It has been a while since I posted video. I shot intending to put it on my Facebook page, which stubbornly displays landscape video rotated 90 degrees. Only after I shot, I realized I never was going to post directly on Facebook, bur rather Here and post links. Landscape for the next one, promise.
I used my Mega4 all through college in the late 80's early 90's and I was doing fully published reports, with embedded graphics, columns, and footers. I was running circles around the 386 computers of the day. If you have the socket for a blitter it made a big difference between mine and my buddies 1040.
I like it. yeah its pre-calculated but then many 8-bit and 16-bit demos were , and ray tracing in real time is a never-a-gonna-happen really in those days .... 6502 at 1.79mhz in the Atari would pump out 0.75 mips if you were lucky. even the stock ST and Amiga were only around 1.x mips. we need some perspective in that the latest i7 would be 221,720 MIPS at 5.0 GHz - hundreds of thousands of times the processing power. even a modest mobile phone nowadays is thousands to tens of thousands of times faster than what we had back in the in early 1980's by a factor of several orders of magnitude. the custom hardware was really where the real magic happened - display list interrupts on the Atari 8-bit or Copper on the Amiga, etc.
I had a rana systems elite one for the apple 2e. I loved all the weird noises it made. Sometimes it would make very loud, angry sounds if it was struggling with something. 😄 I miss that drive!
It's been a while... but where can I find the hard disk image you are using? I'd like to use it on the MiSTer FPGA. I used an Atari 1040STe for about 10+ years. I used to use Geneva/NeoDesk.
1:18 Great move. Flew right between the two enemy ships! This is one of the great Atari 8-bit games. Right up there with MULE, Archon and Star Raiders. Atari should have paid Lebeau and made a cartridge version for the XEGS instead of fighting him over the name. It would have sold a lot of consoles for them.
Check out Atariage.com and the Atari 8-bit computer groups on Facebook. A buddy of mine is a demo coder of old on the Atari, cowrote "Intel Outside". The Atari 8-bit has more than the 6502 at 1,79mhz, It has two dedicated 40 pin coprocessors for graphics, another for sound, an IO chip, a simple MMU. What Atari did to allow these chips to busmaster is to add a halt line to the 6502. Initially this was done with a trio of 74ls chips, until Atari's own "Sally" version with the halt logic integral came into production. No halt line is the major reason we never saw 6502-based machines with front panels and blinkin' lights. 8080, 8085, z80, yes, but 6502 no. With Atari's rig, any 6502 could be such a monster, but Atari used it to share the bus. Antic can directly access memory without cpu intervention and vice-versa. Antic can switch video modes at each scanline, which amounts to a really huge number of possible 'modes' additional to the documented 15 modes Atari supplied. Most of what is being done here is likely artful Antic programming (called a display-list). This demo needs 320k, which is doggone big for a 6502 program. The CPU can modify the display list on the scan line as well, then let Antic do it's thing. You can get answers to how this is done at atariage for sure.
This is super cool. I love the use of inertia to allow the player to move and shoot in all directions at the same time despite the 8+1 input device. I never saw this back in the day, I would have loved it and it would have no doubt influenced me a great deal.
All is well. I lost a custom IC on the Atari and sidelined the project for awhile. I think it is likely the MMU. Since however I've acquired a Hewlett Packard 9000 D230 minicomputer with storage subsystem and terminal. The past couple of months have been interesting. Processor: PA-7300LC (PCX-L2), 512mb ram, 1mb level 2 cache, ten hot-swappable fast-wide differential scsi drives, dual fast-wide LASI scsi controllers.... I got NetBSD on it, but chose OpenBSD instead, primarily due to issues with the iee0 network interface drivers/network stack. I intend to post a video on that machine in the not-very-distant future.
Hey Jeff! It’s been a year or so since your last video. I hope all is well! I sold you a Percom drive a while ago that I saw you nicely fixed up, and I appreciate the little ‘disk switcher’ bundle of wires/connector you sent me for an Atari 800. Thanks for being great in the community!
This is one of the only demos you can't run. It needs a full meg of ram. It might be the only piece of software for the Atari 8 that actually requires a full meg of ram.
TerribleFire TF536 sounds great for the RAM / CPU side of the Atari ST, but the system also needs video upgrades, and has since the 80s and the letdown of the basic STe upgrade. Is there a graphics upgrade for the Atari ST computers? Surely that cartridge slot would allow a drastic improvement in graphics hardware?
there was also VME adapter for regular ST, so you could use NOVA card. I needed a soldering and would not fit inside the ST case obviously. I saw one ST having this upgrade in early 90s.
