00:19:02 - Trying the card and harddrive in my Tandy
00:19:45 - The motherboard
00:23:11 - Outro
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.
Think I found the faulty IC on the xt-ide interface card. Next up is the hard drive. Never had a hard drive be the cause of a computer not posting.
@@RetroSpector78 There is a reset line on IDE connectors - on normal ATA it's pin 1 and probably on XTA too. If that line is connected directly to the ISA reset line, then a fault on the hard drive could also keep the computer stuck in reset.
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.
I'm pretty sure that Samsung was the OEM for the Packard Bell Legend 386/25 that I have, and a later IBM PS/1 486SX/25. They have a VERY similar chassis frame design, and IIRC, the PSU had Samsung markings in it.
you mean the video in which Clint on a tangent told the story of the wrestler who failed his career do to taking an advertisment deal for one model of the said family.
The PC That Ruined a Wrestling Career: Vendex HeadStart from 1987
It was also called the Vendex HeadStart
Yep, early Vendex HeadStarts were these Samsungs rebadged! Along with a half dozen other brands, including early Packard Bells like the PB 500 that I’ve also featured in a video. Samsung was responsible for a big chunk of the world’s low cost Turbo XT clones in the latter half of the 80s.
Same as The Vendex Headstart
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.
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 :)
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
That was my very first PC back in 1989 (on orange monitor though).
Thanks for the memories!
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!
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 one, interesting machine..I wonder what it's secrets are..so looking forward to part two :-)
Nice job DasherDeals, :)
Great video and wonderful system! Looking forward to part 2. XT machines might be slow, but infinitely fascinating.
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.
Much obliged. I hope you have fun with it! 🙂
Thx again ! Has been fun so far !
@@RetroSpector78 looking forward to part 2!
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.
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.
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.
I miss that monitor. The first monitor which my mom had bought for her first PC.😢
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.
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.
Since the power supply works, he can measure the voltages
@@Flashy7 right, just important to make sure it's the standard pinout in a situation like that before you just plug in any other supply
Sure you can! Check continuity between the chassis and the well-known ground pin locations. And use the ISA slots to verify continuity to the +/- 12V and 5V lines. That pretty much leaves you with Power Good, and if everything else checked out OK, it would be pretty unlikely that that ONE signal is different.
@@nickwallette6201 I should've specified "just from it looking like one".
@@Nukle0n ... touche. :-D
Just got a LG 15 inch crt. I'm so happyyy
Kick @R$e Job Brotha!
Really Clean Setup! Uploading the Rest tonight Right?
RIGHT!?!
Nice computer system and nice monitor. Greetings from Steven from the Netherlands
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:
What a beautiful find!
im sure you saw the leaky battery ;-)
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.
could be a problem with the capacitors on the xt ide card that doesn't work tantalum short
I bet its C7 :)
@@dragonlard4595 i'll say c3
@@dragonlard4595 C7 has vent its guts for sure.
My precious !
Same as The Vendex Headstart
Long time since I have seen a DIN connected keyboard.
Great game.. Grand Prix Circuit
Apple vintage computers prices absolutely destroy PC beige counterparts from 40-30 years ago.
I don't miss those big heavy CRT monitors that's for sure
30 kilo Sony trinitron CRT :)
This one is not so bad. 14 inch is a nice form factor. And great to have another EGA monitor.
@@RetroSpector78 It's true. It's the perfect size. I don't know why they even make CRTs larger than that.
@@RetroSpector78 i liked my 16 inch sony crt monitor
@@2xtreem4u i had a 21" lol .. not fun
Good 😊
Did anyone notice the serial number on that monitor 😳
quite unique and nice serial number :>
@@zbysiu3cytrynyevery serial number is supposed to be unique 😅
Tantalum capacitor maybe bad on the XT IDE controller? Or would suspect the 74LS244 ?
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!
If that floppy drive works when connected to the PC without that adaptor board, why is the adaptor board even there?
I wonder if the Samsung keyboard is getting power or is having issues communicating with the computer.
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.
Don't see those old Western Digital stepper drives very often! Have heard they can be unreliable.
Would give that stepper motor of that HDD some lub. Seems not working very smooth.
Put The CRT next to an MRI
If Samsung did make computers, probably it is, even today for Windows and Chromebooks.
That is 36 years old because it's as old as me
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.
Interesting, a Samsung device with a GoldStar (LG) IC chip on it.
Thanks for video, thanks, for all retromania stuff archive. ..xprog 11.90.. and 41256.. goes to .. atari upgrade :D
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)
Dude get that bulging leaking battery out asap. Geez

Well if you can't your in trouble
Oh my god it looks awful, I absolutely love it!
If 30+ goes up to 39, that means Samsung made a 8088 in 1985. But why? 80386 was launched that year.
Intel 8088 was discontinued in 1998. Lots of industrial / embedded systems were still using them.
8086/8088-based computers were manufactured up to the 1990s. Even IBM released a new 8086-based machine (PS/2 Model 30) in 1987. These were crazy times, on the one hand you had a new generation of CPUs and computers showing up every 3-4 years, but on the other hand the previous generations were produced long after they had gotten obsolete.
Weren’t 386 systems several thousands of $$ back in the mid 80s? Not everybody can afford (or wants) the latest and most expensive.
@@ouch1011In fact, 386-based systems only started appearing in 1986 (Compaq Deskpro/386) and 1987 (IBM PS/2 Model 80), and became **somewhat** affordable starting from 1989. And even then there was a huge market for 8086/80286 based machines for less demanding tasks, even in the US.
@@peachgrush Yeah and this one was apparently built in early 1990. The hard drive is from late February and the monitor from March.
nice samsung.....
got any tants on that pcb?
PC Inverted Color Edition
What is the cpu speed of this computer?
very awesome!
Looks stylish
smasnug
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.
WOOOOOOW😮😮😮😮
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.
