welcome back to Joe's computer Museumtoday we're going to install os/2 onthis old IBM warmup the CRT it's timefor another episode ever heard of os/2it's pretty obscure but it played animportant part of modern computinghistory I've never seen os/2 in the wildand I wanted to play around with it as afortunate coincidence I have a machinein my collection that was designed forand originally came with os/2 so itseemed like the perfect opportunity tosee what it's about but before we dig inlet's talk a bit about the machine we'regoing to install it on this is the IBMps/2 model 76 it sports an Intel 486 33megahertz processor 24 megabytes of RAMand a 2 gigabyte skuzzy hard drive itcame from Ford Motor Corporation and hadwindows 95 and an Ethernet card added toitjudging by the grime on the keyboard itcame from a dealershipit's a neat part of my collection andcomplements my other original IBMhardware before I started with os/2 Iwanted to preserve the contents of thehard drive I figured the easiest way wasto just replace it and the best way todo that was a scuzzy to flash memorysolution I'll touch on the process toget the scuzzy to flash solution to workbut if you want to skip forward os/2just click this thing the device I usedis literally called scuzzy to SD it's acustom board that connects to the 50 pininternal ribbon cable of your system andemulates a scuzzy hard drive you use thedownloadable utility to set the size ofthe partitions update the firmware andmore after that you just pop in an SDcard hook it up to your system andyou're set with this machine however wehave a little problem because it's BIOScode lives on the hard drive if youreplace the drive you'll find themachine magically stops working you haveto somehow transfer the code from theoriginal drive to the new one it took abit of research to find out how to do itbut luckily IBM made this fairly easypressing control insert during post withthe original drive in the machine getsyou into utilities that allow you tocreate special floppy disks these disksare used to boot the machine and writethe bias to a new drive with that out ofthe way the computer recognizes thescuzzy 2 SD device and we're in businessnow let's get back to os/2 os/2 wasoriginally developed jointly byMicrosoft and IBM as a modernplacement for ms-dos its name short foroperating system - was a marketingtie-in to IBM's PC systems at the timebranded personal system - os/2 usedprotected mode to natively unlike daswhich nominally used real modethis made os/2 in theory anyway morereliable than das with better supportfor modern hardware that said a primarydriver during development was to ensurecompatibility with DOS applications totake advantage of the sizable dassoftware library and at an API level itmimics ms-dos to facilitate this asdevelopment of the OS continued IBM andMicrosoft had differing opinions of whatthe OS should be in the end they partedways on the projectIBM continued to develop the os/2 lineof operating systems while Microsofttook their version reworked itsignificantly and came out with WindowsNT a series of operating systems thatexist to this day so whatever happenedto os/2 would you believe me if I toldyou it was still around that's right theold beast still exists despite its ageIBM only dropped official support in2006 and still gives defect support fora fee because of its incrediblereliability it's running inside ATMs andembedded systems of all kinds supposedlyit even runs parts of the New Yorksubway system you can still getrelatively modern versions in the formof e comm station and ARCA AHS toauthorize systems based on os/2 how'sthat for longevitysince this machine came with version 2.0I installed that first I also tried outos/2 warp installing either version ispretty straightforward you use theinstallation floppies to install version2 and a boot floppy with CD to installwarp you should be able to find theseonline here's a time-lapse of theinstall of warp because the process isreally rather boringyou[Music]now that we've done the install let'stake a look at both versions all rightso here we are booting up OS to version2.0 the version of os/2 that thiscomputer was theoretically designed torunthere's our pretty boot screen with theos/2 logo and multiple different colorsI always found it funny how when theseold loading street screens they sayplease wait they're like please don'tget upset at us that this machine isinsanely slow and takes forever to loadthis guy takes a little while but it'sactually quite a bit faster than youmight expect because we are loading fromflash so there's really no head weightit's pushing data as fast as the scuzzyinterface can push it we have our mousecursor here neat to see that the mousecursor is black with white borderinstead of the other way around my beingreally didn't want to do do the do thewindows convention there and here is ourour entire operating system it is prettysparse as you can see the design issimilar to the way Windows 3.1 workswhen it has minimized windows as amatter of fact you can even see thathere the system is set up so that you'vegot like the os/2 system here which issimilar to I guess you would call itkind of like the program manager so youcan go in and see the applications thatare on the machineyou've got the shredder here which issomewhat analogous to oh I don't knowkind of analogous to the trash or therecycle bin on other operating systemsgo ahead and close that and help isbuilt in obviously because you're goingto need it to figure out this operatingsystem because it is a little bit weirdit's a little different it's easy enoughto get around if you just think for aminute you've got your window controlsup here which are a little bit differentthey're similar to what you might see inother operating systems but the theglyphs are differentyou got your closed menu in the upperleft again similar to Windows 3.1 heckit even looks like a Windows 3.13.1 men using the standard go windowsfont there and everything closed thereand it closes it out that's really allthere is to it you know if you have yourapplications installed they're going tobe in here you'll have an icon on thedesktop here let's see what a minimizedwindow looks like double click that andit doesn't look like that at allso yeah even I'm having a problemsfiguring out how this is supposed towork exactly but that's fine close thatand that's really all there is to os/22.0 it's pretty flat and when you wantto shut this down it's the funniestthing there is no user interface here atall if it helped you figure out how toshut it down you have to right-click inthe middle of the screen here and selectshut down and then hit OK you gotta lovethis message - are you sure you want toclose or select ok to continue shutdownselect cancel to end this task good onthe IBM from being super officialinformal there so we'll go ahead andclick OK and end our os/2 2.0 sessionplease wait shut down still in progressdo not touch that power button oh mygosh you might break it or something andnow there it is ready to be shut off sonow let's take a look at oh s 24.0 warpall right so let's load upos/2 4.0 warp you can see the bootscreens a little bit different andthere's our os/2 warp boot screenbeautiful Bezier curve on the font theygot there just the tip top of themid-90s technology so this is going totake a little while to load because it'spoor ol computer slow but will bear withit all right now we're loading up thedesktop got to love that waiting cursorit's an entire clock none of this watchor hourglass uh for IBM no no we got togo with the full wall clock that lookslike a monitor whateverIBM was really never known for theirstriking industrial design they justbasically made stuff that worked so thiswill take a little bit to load up herecue the jeopardy music in the backgroundwhile we're waiting I guess there we godesktop background and icons andeverything so this is os/2 4.0 or asthey call it all your standard icons andstuff there so let's take a quick quicklook at this first major thing is thoughas to warp a menu up here this is arange kind of like the Windows Startmenu a little bit you got certainapplications that have their own hotmenus here program shows your programlists os/2 system you can kind of thinkof this a little bit like the controlpanel but not exactly connections willshow you connections to your differentdevices in assistance center is yourhelp this up here I guess you wouldconsider it the taskbar although itdoesn't really function that way it'smore of a shortcut bar that has links toeverything that's already on this menuagain for whatever reason this was moregeared towards your power user so thoughyou know everyday users might get someuse out of this they're not really goingto be looking looking for all the stuffon here they really don't care thisshows you know your your drive and yourCPU usage and all that a couple weirdlittle things about the the way thisworks as far as user interface paradigmlet's let's open up an application herewill open up this user interface lookskind of similar to I don't know WindowsNT 4 or Windows 95 a little bit you havethe icons here or thecontrols here a little bit differentthis menu still looks like a Windows 3.5menu and moving icons around on thedesktop is really weird you gotta likeright-click it and select pickup andthen you get this this briefcase thingand then you clickyou want it to go and you hit drop hereand moves it that's weird you can't likedrag-and-drop icons it's really reallyfunky of course comes with NetscapeNavigator pre-installed or the get thingfor it and then web Explorer which isIBM's IBM's browser now I couldn't getthe ethernet card to work on this so Ican't really browse the web with it butapparently you can get a relativelyup-to-date version of Firefox you canactually surf the web on this thingwhich is kind of amazing to shut thisone down it's a little bit easier than Iwas - version 2 we have a dedicatedbutton for that so we just click thatthere are you sure you want to shut itdown we hit yes and it shuts down prettyeasywell that's OS os/2 4.0 warp in anutshell os/2 is pretty nifty and had agreat deal of promise to be theoperating system the future butMicrosoft's keen marketing and businesssense put a kibosh on that today windowsreigned supremebut under the hood of any modern Windowsmachine is a little bit of the soul ofos/2 so in a way it lives on well that'sall for today's video while you're herecheck out some of my other videos andremember eight bits are all you need[Music]you
