My mic came unplugged for one take and when I reshot it I forgot to talk about the change I wanted to make to mail videos. It's not much, I'm just going to start asking people to write the name they want to be called or have a mention to keep it private on the box because it isn't easy to find every source of where I talked with someone before they sent the package if they were okay with me saying their name. I've tried making a document to keep it all in, there are a few things that make that hard to use that I wont go into but it doesn't work out well for me in the end. That's all I wanted to mention about it.
Your welcome for the socket 7 board, can't wait to see it in a build! Looks like you've got lots of goodies to build a system but let me know if there are any other parts you need... I have "a few" extras from the era :P
30:25 That slot is for a proprietary 32-bit memory expansion card. There weren't standards for such expansion cards so you'll need to research what might work with your motherboard. When those boards were being made, there were probably only 256kB or 1MB SIMMs available (or at least the only ones that were reasonably affordable) so you needed a lot of slots to get to more than 4MB of memory. My 386 back in the day had one but we never got the card for ours. Good luck finding one!
You are absolutely one of the few "retro" tech personalities whom mixes absolute thorough knowledge with great personality and humor. I also love the vibe of late 70's early 80's prog rock/D&D style. It's an era just before I was born (1984). Fascinating channel.
Just saw the video this morning. Glad the calculator made it in one piece. It's awesome that you got it working and I'm looking forward to seeing how you got it working.
Some of that 72pin SIMM RAM might be FPM and not just EDO. It's worth carefully checking because in general 486 machines need FPM and Pentium machines can take either.
7:00 Appears to be an Abit BP6. CHECK THE CAPS, they're known to need replacing. Also, from the factory, they're only setup for Mendocino Celerons. Uses an Abit 440BX chipset, so with some modifications, or socket adapters, you can run atleast Coppermines. I think Tualatins as well, but don't quote me.
It does look like a BP6! I had one of those that I ran BeOS on, just because it had SMP support back when mainline Windows did not. That puppy ran HOT. I went to all the trouble of water cooling the CPUs, and found the north bridge chip to be the hottest thing in there. It was fun but not really worth the trouble. I would do it again in a heartbeat though. ;-)
The Data General Nova video is what got me into your channel and I've been curious as to what's been going on with them, so appreciate you giving us a quick rundown!
I think I am following your channel for 4 years. I always shooked due to your awesome solution about the computers. . Also I decide you love the nostalgia things about the computer or other things. So why I am following your channel and I will too.
I love your videos man, Found you with the 1970s Data General Mini Computer video, your an excellent wealth of knowledge on old school Computing, and i hope you continue to make stuff!
Capacitor reforming isn't a safe option, it's a reprieve at best. I hope you have a really sensitive leakage tester to verify they are OK because LCR meters don't give the full picture. If these aren't some kind of unique capacitor then please replace with modern alternatives. Mr. Carlson's Lab has a nice chunk on testing caps in a recent video you should check out ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-0rf-fO0aj3I.html
The capacitors are huge, soup can sized. It would probably be $300-400 to replace them all instead of reforming. They are huge screw terminal types, not your every day 120V filter caps. They are possible to replace, but I really don't want to unless I have to.
@@TechTangents I agree with Morinaka25 in that reforming is a reprieve. It also only holds if you run the equipment regularly or it may reverse again. The old capacitors may be soup can sized, but modern replacements might not have to be, capacitors came a long ways. What kind of voltage rating AC and DC and capacity are we talking about? That would tell much more than physical size. Depending on the what and where you might also get away with using for example motor run capacitors. "high" voltage but cheap.
WOW! An Abit BP6 that takes me back! I had one of those with two Celeron 400s overclocked, I think 600MHz, somewhat stable. R_SMP 01 in Q3 Arena timedemo is burned into my mind.
@12:42 I did that with my maths books for my C64 graphics stuff. Maths teacher didnt think it was such a great idea. :) Never knew something official like this existed.
NI's hardware was pretty expensive too. Especially if you got into the PXI stuff. I can tell it holds its value just by the USED prices on ebay even though some cards are 15-20 years old.
I owned one of the BP6's. As others have said, it's celeron only. Dual celeron 366's overclocked to 550 and would crush anything thrown at it..... if it ran on linux or NT4/win2k. It was my daily driver back in the late 1990's. The other huge thing is that at full load it was unstable because one of those capacitors is wrong near the CPU. Recap kits should cover you. Thanks for the memories and you wonderful videos!
25+ years ago, I worked with a guy that used to buy auction pallets of used PC's and computer bits.......the amount of cards, boards and peripherals we TOSSED in skip bins over that time was formidable. I went on ebay the other day and saw an AD for a video card I had around 1989-90, at one point, we threw 160 of them and similar cards in the bin....2Mb and 4Mb AGP stuff and the like.....the 2Gb card on ebay SOLD for $79USD.........if I was to total up at this kind of price, we DUMPED about $500,000 worth of kit in a 12 month period alone.....it makes me WEEP now thinking back on it......especially now as I have NOTHING older than a P4 board here now, and it wont run Windows 95 or 98. It works, but no sound or graphics drivers I have tried will work on it. It can do a full XP, but anything before that era, I have to use VM or EMU, and I had about 20 Win98 class PC's here, but I tossed them all in the bin about 5 years ago.....if only I knew OLD RUBBISH would be worth more than Gold Pressed Latinum now......
Geez, I got a customer bringing such a Pentium III motherboard, when I realized how strange that stuff was and how cool would it be to have it in the future (this was around 2012) I asked him to sell it to me, but he denied. That's sad, I was even thinking about giving him a better machine in turn, but well, that's how life goes.
I have an "internal" LS-120 drive. I found it on eBay, and it turned out to be from one of the USB ones (the ones that were colored like iMac G3s). Inside those are just IDE-to-USB convertors, so you can take the drives and install them internally. The only downside is you don't have a nice front bezel.
"Memorex Trackball." That narrows it down to two - one that has an adjustable rest, and one that's essentially a box with three buttons and a large trackball.
So jelious of all that EDO ram :( I have on idea how much I have as I've never accumulated it into one place, but it might be about half or a quarter of what you have there. So beautiful. I have hundreds of 32pin SIMM's though, so I can't be too jelious :) Some of them are 4mb which is nuts
Irrelevant trivia: Rochester, MN is the location of the original Mayo Clinic. (The Mayo Clinic and it's subsidiaries employ a number of people greater than 25% of the population of Rochester just at their Rochester site.)
And the the other half was employed by IBM when they had the AS/400 plant. I have been there in the late 90s and loved it! I am not sure any of those plants are surviving now.
@@hernancoronel According to the Yellow Pages, IBM is doing business at at least three different addresses in Rochester. The AS/400 line (the current line is called the IBM System i) is exactly the kind of product (high value add, high markup/high margin business-grade equipment) that the US continued to manufacture in volume after consumer products almost universally went overseas for lower regulatory costs. I wouldn't be surprised if they're still making them in Rochester.
I don't think that's correct. It uses 8 1MB flash chips: pdf1.alldatasheet (dot) com/datasheet-pdf/view/66038/INTEL/E28F008SA-120.html and usual COAST modules have a different connector. Please let me know if I'm mistaken.
For the HPIB cards.. You can use them with your HP-86! There's an awesome program called HPDrive that lets you emulate an old HPIB disk drive with one of these cards. Paired with LIF manipulation utilities, you can do a whole lot to make the 85 series more usable. Edit: the NI card will work with that^ out of the box. I use one of those. In fact, it might be the only one of the 3 that's natively supported
Oh wow! That's really good to know. Especially since I just picked up an HP-85 as well and I'm now going to be trying to get software on and off of it. I'm trying to get an I/O ROM and second drawer now to make the GP-IB module usable on it, I'll double check if I need another one for accessing disks.
Tech Tangents The HP-85 will need a Mass Storage ROM to access disks afaik, and the 85B has this and a few others built in. ROMs are an expensive PITA to find though, might be worth building a clone of the Programmable ROM Drawer instead? Could make for a cool video too lol I mentioned more about that on the Discord yesterday
You have an astounding amount of power. I have just discovered your channel and it fills me with fear in a good way. Please provide me with some tips on executive function because holy shit, how do you get so many projects done so quickly
I thought I would comment and say it's pronounced Elyria (/əˈlɪəriə/ ə-LEER-ee-ə), and Cleveland is the closest major city, so you were right in putting the magnet on Cleveland
Great video! That dual P3 motherboard would run Windows 2000 very well. I would have loved to have that setup back in the day, as an audio workstation.
That display adaptor I used in addition to get debug output if I'm not mistaken on a 2nd screen, main screen was some type of SVGA 1024x768 'true color'
That unknown edo you thought was flash, might be a cache sim for a mac classic, lc2 or performa line of computers. i remember seeing that one in one machine i had, but not really sure what it was in
You have to know that the nec v20 has a built in intel 8080 emulation/compatibility so with special software to activate it you can boot CP/M and be able to run programs natively
The graph paper looks like it's almost certainly for the TRS-80 Model I or III. It should have 16 rows, labeled on the left with numbers counting 0, 64, 128, etc, with each large cell divided into two columns, three rows. Does that one have the program planning/flow-charting page on the reverse? (It would be great if you could post a scan of that. I've made a worksheet that duplicates the functionality, but it would be awesome to have a scan of the original to try to duplicate the aesthetic.)
I have some 1000Mhz Piii socket 370 CPUs & a lot of PC 100 RAM if you need some. I always wanted to try a dual Piii board. Also have some AGP & PCI video cards.
How do you use that 486 pc on a card? i have one and have no idea what to do with it. Would love to know, sorry if this is a stupid question... Chris...
Start by getting the manual for it. That should tell you how to power it. It also certainly helps if you have an old IDE hard drive, floppy, PS2 mouse and keyboard. USB was pretty much non-existent on 486's.
I have a 4-drive controller that does all four drives on the primary controller (which I think is neat because DOS actually supports that natively -- I have not figured out how to get DOS to address a secondary controller without extra software involved). Unfortunately I discovered that mine does not do single density, and I've been having to get out my CompuAdd every time I need to deal with single-density disks.
