Somebody gave me a 30+ year old Samsung PC 

The Tandy obviously revealed something. It is stuck in Reset (or interrupt or with no clock signal - but I assume reset). The humming noise comes from the uninitialized sound chip. When an 8088 goes out of reset, it will look at the address FFFF0 (or in segment/offset F000:FFF0). There, the BIOS contains a JMP command which jumps to the first commands of the BIOS POST. This is, why this command is called the Reset Vector. The first thing that a Tandy 1000 does after the reset vector is to mute the sound chip, so the humming goes away after half a second to a second. When you plug in your faulty controller, the system is likely stuck in reset or interrupt or the clock signal vanishes, so nothing is executed. If you have a POST analyzer, this won't give you POST codes on an XT but you can watch the Reset signal, which is active-high. You can also analyze the reset and clock pin on the CPU and the various interrupt pins on the ISA bus with an oscilloscope. Then you roughly get an idea on which of the logic chips or maybe even passive components (like a pull-up or pull-down resistor) you have to look for the problem.

Such a great donation AND how nice of that DasherDeals seller taking the trouble of uploading the voice card software, which of course requires using vintage hardware to read the disks and all.

That was my very first PC back in 1989 (on orange monitor though). Thanks for the memories!

OMG i grewup with this pc! you have the original box also!! omg so mutch memories, i still have the hard disk. Mine had the HD under the floppy. And my monitor was orange

Great video and wonderful system! Looking forward to part 2. XT machines might be slow, but infinitely fascinating.

I love the level of integration of this PC. One chip to rule them all :) Reminds me of NEAT and SCAT for 80286-based machines. Thank you for the video and looking forward for part two!

Nice one, interesting machine..I wonder what it's secrets are..so looking forward to part two :-)

If I'm not mistaken, this PC was manufactured by Samsung for other PC makers who just slapped their badge on it. I think Packard Bell may have been one of them. I believe I learned this from an LGR video.

These were rebranded and sold as the Packard Bell PB500 and under the Epson Apex series, although I believe Samsung is the actual OEM. It's a solid platform that takes upgrades like a champ. I have an Epson Apex Plus, and I've upgraded it with an NEC V20 CPU, 8087 math co-pro, Tseng ET4000AX SVGA card, a Sound Blaster Pro-compatible sound card, and an XT-IDE card with a 130 MB hard drive. My next upgrade will be an Ethernet card :) I believe DasherDeals is run by JJ Dasher, who used to be a prominent member of the vintage computing community, so it's no surprise that he would do that :)

Nice job DasherDeals, :)

Brings back so many memories. Our first home pc was an 8088 IBM PC with a 10MB RLL or MFM hd(cant remember). I thought it was massive at the time. Now a 10mb file is nothing so any storage medium of that size would be worthless.

Nice computer system and nice monitor. Greetings from Steven from the Netherlands

Kick @R$e Job Brotha! Really Clean Setup! Uploading the Rest tonight Right? RIGHT!?!

My precious !

I had its predecessor, the SPC-3000. Same dual-speed 8088 processor, but mine had two 5.25" floppy drives, the same 12" amber monitor Atari used for its PCs (Samsung-branded, of course), no sound card, 640KiB of RAM, and a dual-mode (Hercules/CGA) graphics card.

I miss that monitor. The first monitor which my mom had bought for her first PC.😢

What a beautiful find!

Have the same pc but with a ks-4 videocard and a st-238 hdd. Btw if you didn't know, the pc is a turbo xt, can run upto 10MHz with a keycombo.

good that you remove all the cables and stuff but leave the battery in, so it can leak and destroy the device. Well done, nice work.

The company who made that keyboard, Sejin, had a short period of fame in the mid-1990s with a product they developed called the J-Mouse Keyboard which had an eraserhead pointing device under the 'J' key.

Another cool find! Stinks that the HD and IDE card are no good. I'm 99% certain I had a VGA Samsung monitor in the 90s that came in that exact same form factor. As with so much, of course I have no idea what happened to it.

Good 😊

That’s a very late 8088. I’m actually surprised that it wasn’t a 386 or even a very early 486 given it was built in 1990 Pretty sweet

Pretty sure when you removed the floppy adapter board it was connected to the cable before the twist making it drive 1 or B: instead of drive 0 or A:

Great game.. Grand Prix Circuit

Thanks for video, thanks, for all retromania stuff archive. ..xprog 11.90.. and 41256.. goes to .. atari upgrade :D

Same as The Vendex Headstart

Tantalum capacitor maybe bad on the XT IDE controller? Or would suspect the 74LS244 ?

Did you noticed the bent legs on the faraday chip? There is one that looks a bit like if it has broken a trace, not 100% sure as I cannot clearly see it on the video but it looks wrong.

Funny about the UDMA IDE cable. Not sure this works. I think this PC was used with the Galaxy Communication system. Schindler used it. But I guess also some other brands of elevators.

Long time since I have seen a DIN connected keyboard.

Even though it's the same 10-pin connector you can't be entirely sure it's wired up the same as the "standard" AT style.

im sure you saw the leaky battery ;-)

Just got a LG 15 inch crt. I'm so happyyy

I'm looking for the *Samsung SPC-650* homecomputer. It looks identical to the Sinclair ZX Spectrum+, but has an extra Samsung logo. Let me know if you have one for my collection!

Found an HP Compaq at St Vincent for 15 bucks. missing HD. Just retro built another Sunday Brand new in the box Soyo Socket A MB have 2 Athlon and 1 Sempron CPU's put in the Athlon. Was in my basement. Have been messing with hardware since 1996. My basement shelves look like a PC store. Needed an IDE connector and Serial Port for some old hardware, Still have NIB Intel and Tyan Slot 1 Pentium III motherboards in the box never built a pc with them. They have just been on a shelf. Got 3 PIII CPU's and 3 extra Slot adapters. So may end up getting one up and running.

very awesome!

I wonder if the Samsung keyboard is getting power or is having issues communicating with the computer.

Don't see those old Western Digital stepper drives very often! Have heard they can be unreliable.

could be a problem with the capacitors on the xt ide card that doesn't work tantalum short

Much obliged. I hope you have fun with it! 🙂

If that floppy drive works when connected to the PC without that adaptor board, why is the adaptor board even there?

Would give that stepper motor of that HDD some lub. Seems not working very smooth.

Put The CRT next to an MRI

What is the cpu speed of this computer?

got any tants on that pcb?

NC 화면이 나올때 나의 어린시절이 생각 났음...

you sound sick in this one, are u? (because i just watched a 1 month old video, and you just sound under the weather in this one)

WOOOOOOW😮😮😮😮

I don't miss those big heavy CRT monitors that's for sure

Oh my god it looks awful, I absolutely love it!

Looks stylish

Apple vintage computers prices absolutely destroy PC beige counterparts from 40-30 years ago.

If Samsung did make computers, probably it is, even today for Windows and Chromebooks.

Interesting, a Samsung device with a GoldStar (LG) IC chip on it.

That is 36 years old because it's as old as me

nice samsung.....

Well if you can't your in trouble

Dude get that bulging leaking battery out asap. Geez

PC Inverted Color Edition

smasnug

If 30+ goes up to 39, that means Samsung made a 8088 in 1985. But why? 80386 was launched that year.

Did anyone notice the serial number on that monitor 😳

30+ = NOT 1994, right? (Oh, West-Germany) ^YES-yes, i'll STFU and watch...now

That computer makes a horrendous noise! 🤣

Samsung, lg không được tốt lắm, các sản phẩm từ Đai Loan tốt hơn.

Oh my! The first 7 seconds gave me PTSD Lugging those monitors and related equip around. Then the 21" CRTs arrived Hooking up. Unhooking. Repeat. Along with all those 'users'? Thankfully it was before the Interweb access I'm glad it's in my rear-view mirror. But very COoL stash!! Thank you Mr.Ben. p.s. They sure are packed better than 90% of [my] eBay purchases Cheers from So.Ca.USA 3rd House On the Left.
