[QUOTE=Banshee FrieNd;34432825]okay, I'm going to practice on the chips on an old hard drive's logic board. What kind of flux should I use?[/QUOTE] Radio Shack sells small tubs of flux for a decent price, and it'll last you for ages.
Spent the day in Seattle visiting the museum that the Seattle Retrocomputing Society has setup with the help of out friend in science, Paul Allen. I showed off my Rainbow 100, MicroVAX 2000 runnign VMA 6.2 and my Compaq Portable 386 running the No$GMB emulator.

Picked up another [url=http://en.wikipedia.org/wiki/SGI_Indigo]IRIS Indigo[/url]. It's a base system. 33mhz MIPS R3000, 32mb ram, LG1 Video (2D graphics only...from a company whose specialty at the time was 3D) and a 430mb hard drive. Well, I guess the only good thing going for this system is the annoying ad SGI made for it. [media]http://www.youtube.com/watch?v=vjUfgDO19-I[/media] Did however have to repalce the battery. It uses an awful 3.6v cell and it's cheaper to just replace it completely with a 3V CR2032 which is easy if you have some spare time.

Finally got the PDP-11/23+ to do something besides waste energy. Figured out I had a cabling issue and an incorrectly set jumper that was disabling the external baud rate generator. Now I can get a console prompt.

It seems the list of bootable devices is hard-coded. In other words: [url=http://www.visionnet.nl/joomla/images/stories/history/hdd/st-506%20extern.jpg]DSA = DEC RD50/RD51 = Seagate ST-506/ST-412[/url] [url=http://staff.salisbury.edu/~rafantini/IMAGES/pdp11/rl01a.JPG]RL01/RL02 = Removable Disk Drives[/url] [url=http://members.optushome.com.au/intaretro/RX01.jpg]RX01/RX02 = 8" Floppy Drives[/url] [url=http://www.sparetimegizmos.com/Software/images/tu58.jpg]TU58 = Super Obscure QIC Tape Drive[/url] It has no immediate clue what SCSI is, nor can it see my [url=http://www.cittb.net/mark3/03092011%20004.jpg]RX50 5.25" floppy drive[/url] which I require at the least so I can boot into a basic copy of RT-11 (yes, a version of a minicomputer Operating System that can fit on a 400kb floppy disk) and begin setting the system up.
128 Kilowatts of memory? :v:
If you follow the computer illiterates thread, you would know I trashpicked an iMac 5 days ago. There was snow on top of it when I found it, and some went into the air vents. So I brought it home and waited until today to turn it on (so it could dry). [media]http://www.youtube.com/watch?v=-JAkLo_W8zo[/media]
[QUOTE=AugustBurnsRed;34632946]128 Kilowatts of memory? :v:[/QUOTE] KiloWords most likely.
I found out yesterday the Windows 95 of my childhood I had in my room when I was like 3-6 or something, was actually infact a 3.1 Turns out my dad had a load of them them from work, and still has some, but when we moved house last may we *cringes* threw out a lot of old PC's we had because we didn't have space anymore :c
Anybody interested in an UNOPENED apple HyperCard? A thrift store around here has one for $20.
Why spend $20 on 14 year old software when you can get it from abandonware sites like Macintosh Garden? [url]http://www.macintoshgarden.org/apps/hypercard-241[/url]

[url]http://www.macintoshgarden.org/apps/hypercard-241[/url][/QUOTE] Because you get all of the documentation with it? I tried making stacks with no references and it was a nightmare.
I was just seeing if anybody wanted it.
[url]http://www.ebay.com/itm/320846677704[/url] You know, I remember when this hardware had no value. I got my cube in a trade and paid shipping both ways to give the guy my Macintosh SE and his cube. I remember last year I was ordered to sell a boxed and mint NeXT Station system with monitor and printer plus documentation and I had maxed out the hard drive and memory and done a fresh system install and we had to lose money on the deal and sell it to a guy locally for $250. The only thing NeXT had that was of real value was their Dimension boards but that was simply because they were always an uncommon option. Then Steve died. That egomaniac that took the computer illiterate mac world by storm and became their god had died. Everything changed. Anything that he had even been in the same room with when he coughed suddenly was worth MILLIONS. And that in point, Here's a NeXT Cube that has sold for $10000 because someone is an idiot.
Oh wow.
I have my G4 Cube up for sale $20000 cash only please
I just got a new revision 0 Commodore 64 the other day, every single chip on the mainboard is socketed, this is gonna make repairs easy. All that was up was a blown internal fuse and a slightly dented commodore badge which has been straightened out.
New 386 components came in. [IMG]http://i11.photobucket.com/albums/a166/ballsandy/Computer%20related/100_2589.jpg[/IMG] [IMG]http://i11.photobucket.com/albums/a166/ballsandy/Computer%20related/100_2591.jpg[/IMG] That's full size AT by the way. That was about as big as you could get for motherboards back in the day that fit into a regular case. The board is an American Megatrends 386-AT. It features: -Support for up to 16mb of ram (640K onboard + 8mb in 4 x 2mb 30 pin SIMM + 8mb in an AMI proprietary memory expansion) -33mhz Intel i386 with full support for the i387 and Weitek math co-processors -Six 16-bit ISA slots and two 8-bit ISA slots -Combination Floppy/IDE/parallel/serial I/O card with Paradise VGA (with upgradeable VRAM) This is the motherboard that all asian clone makers built from. If you look around you will find in old magazines the exact same board with [url=http://ummr.altervista.org/images/DSCN5792.JPG]slightly[/url] [url=http://ummr.altervista.org/images/DSCN4888.JPG]different[/url] [url=http://ummr.altervista.org/images/DSCN6373.JPG]layouts[/url] but otherwise, it's the same thing. This kit of boards would of cost a lot back when the 386 was first released and given you [B]one hell of a fast computer.[/B] Edited: Also, that NeXT Cube that sold for $10000 has been relisted. Apparently there was an "accidential bid". :rolleyes:
Just picked up a Commodore C386SX-LT laptop from a flea-market the other day, came with power supply and everything. It's from 1991 so it's not that old, it's essentially a basic x86 system with the C= brand. The computer is in surprisingly good shape save for a scratch or two and worn out screen, everything seems to be working well so far. I have yet to determine if the floppy drive is in working order though can't seem to use any of my disks, can't even format them; I can't tell if it's the drive's fault or not, have yet to install a floppy drive on my PC. Currently runs MS-DOS 6.2 and has Windows 3.1 installed. MS Word runs terribly slow :v:. 16MHz i386, 1MB RAM, 15MB HDD and a monochrome display.

Try to format a double density floppy instead of a high density floppy and see if that works.
Tried that, still not working, same error as all the others, "invalid media or track 0 bad - disk unusable". I'm leaning towards the problem being with the disks, I tried them on another computer at my Uni's campus and it can't read them either. They were all stored together, perhaps I brushed some magnet against them one day or something. :/ [editline]12th March 2012[/editline] Aw man why did I throw out all my old serial mice grr
Not sure if this counts, but I hear the Commodore 16 counts as retro computing. So it's time for me to brag about the Commodore 16 that has only been played a few times, everything including box, for free.
[QUOTE=bigdoggie;35110747]Aw man why did I throw out all my old serial mice grr[/QUOTE] I'm guilty of that too, time to find an original IBM mouse now :(
[QUOTE=inconspicious;35111636]I'm guilty of that too, time to find an original IBM mouse now :([/QUOTE] I still have a serial mouse but even my Epson 500c has PS/2 ports which makes it useless unless I get something older.

Hi all. Found this forum by chance and thought I'd butt in the conversation with my own little retrocomputing gem: a Compaq Portable II from 1986. 286-8 (slowest 286 of them all!), 640kb of RAM, one 20MB stepper-motor hard drive, running DOS 6.22. The computer actually has an IDE controller but Commodore found it cheaper to ship 20MB MFM Miniscribes with a dedicated converter than to ship IDE drives in the first place. This fortunately allows for replacement of the Miniscribe with a straight-IDE drive, of which I happen to have one (a 40MB Quantum Prodrive). This is of particular interest to me since the stock Miniscribe, while still working perfectly, has the habit of randomly emitting a [b]very[/b] creepy whine that reverberates through the house. I think it's the magic goblins inside the drive all screaming as they die. Or it could just be the spindle bearing on its way out, but come on, screaming magic goblins are so much cooler. Speaking of drives, I also had to remove the existing 5.25 floppy drive; I don't actually know if it works or not because I don't have any 5.25 disks, and I found it cheaper and more efficient to put a 3.5" drive in its place than to source 5.25 disks on eBay that may or may not work. I actually use this old thing for something practical: I put an old ISA network card in it, and (after a ridiculous amount of swearing to get it to work) I can now connect it to IRC. Here's two pictures while I'm doing exactly that: [img]http://www.technfun.com/various/tech/cp2-irc1.jpg[/img] [img]http://www.technfun.com/various/tech/cp2-irc2.jpg[/img] And [url=http://www.dutchforce.com/~eforum/index.php?showtopic=33219]here[/url]'s the repair log, including the exciting story of how I removed dozens of dead spiders from its guts. I might eventually get rid of its ridiculously loud mains-powered PSU fan and replace it with a much quieter 12V one, because as it is it makes more racket than my main box - and my main box isn't exactly quiet itself. I have somewhere a picture of the computer with its guts showing while I was testing hard drives, but I no longer remember where it is. If I find it I'll post it.
