If the tantalum caps blow in 30 years.. I'll be the only one with a soldiering iron at the old folks home.
A working 5160 with HDD, AST 3G video card and FDD? And they even threw in a free spider? Outstanding!
Leisure Suit Larry Installed on a business computer. Yeah that checks out, was probably installed on more work computers than home computers
That original hard drive/SSD size comparison. EPIC!
Wait, was that leisure suit larry? Hahahah. Awesome!
Thank you for letting Leisure Suit Larry theme play.
Nice 5150. Steven now work on a 5170. Greetings from Steven from the Netherlands
Few years ago I picked up two 5160s, an older model and a newer revision, both completely full of cards and they ran... no bad tantalum caps on the motherboards or cards. Now that I have said that out loud I suppose next time I power them on all of those caps release their magic smoke.
I like to clip the caps with a flush cutter and desolder them from the top side due to the bent legs
Again, you don't need to have exact value for filter caps like tantalum and electrolytic.
Quick follow up… Recently I had a paint project that required sandable primer. I remember thinking the text of the primer felt exactly like the IBM PC case. If the color match values for auto paint can be found, the combination of the primer and the paint could be the solution. When it comes time to paint it, unless you are good with an airbrush it may be better to strip all of the paint off the case and repaint the whole thing.
the dirty little secret of EGA is that almost all games are basically CGA with 16 colors. there were only a handful of games that actually had 350 line modes (sim city being the only really significant title). EGA monitors are pretty much useless expensive doorstops unless you're interested in specific productivity software or the few games that could do 350 lines. certainly game companies could have made 350 line modes, but they didn't because most people would be reusing their CGA monitors and they didn't see the point in dedicating resources to another 16 color version
Spider bro was installing the web on the computer.
No web-browsing for you on that machine now, since you threw out that spider .. 😄
Hi, with the paint.
Later model 5160’s shipped with 1 or 2 half height floppy drives. Yours is identical to what I have, it’s an original part :)
The emulator board is to emulate a 5250 Terminal. They were used by IBM's midrange systems, not the big mainframes. The midrange systems were for small to medium size businesses. The connector at the back was converted to a twinax coax cable and then connected to one of the midrange systems like System 34, System 36, System 38 up to the AS400 range of systems. The metal cover of the PC has a hammered surface, so it's not enough to sand and re-spray. Some have had them powder coated to get a similar finish. I've seen floating around statements that IBM used Pantone 413 as the colour of the case, but have been unable to find any authoritive source for that assumption.
Spider saved! :)
If by "EGA-like graphics on a CGA display", you mean 320x200 and 640x200 with all 16 CGA colors, those will work on CGA displays, provided the jumpers on the card are set for a CGA monitor. It's just like how PCjr/Tandy graphics work on a CGA display. As far as the monitor cares, CGA, PCjr, Tandy, and those two EGA modes are identical.
