These old ads are great, really takes me back to that era. In the mid to late 1990's I was a pimply faced youth in community college and picked up a part time job doing "PC repair". I couldn't put my finger on it, but the outfit carried itself like it was a major corporation despite being a small office, it was called TSS (Technology Service Solutions). The majority of the other guys were always working in the field so I wouldn't get to know them until many months later. When I got my first paycheck (physical paper), it said IBM on it. I asked my boss why this was and he nonchalantly said "we just use IBM's payroll system". I was very confused but didn't ask any further questions.
What I came to learn later was that TSS was IBM's PC service division which it had sold off to Kodak just a few years prior. I spent most of my time doing contracted in-home PC repair for all the major PC brands of the era, including Gateway. I'd get a service call (on a RIM bullfrog two-way pager), call the customer and tell them "Hi, I'm with , give me directions to your house and I'll fix your system". Most of the consumer PC manufacturers were unequipped to provide any kind of in-field repair service on their products, so they hired TSS for this. If you bought any kind of extended warranty on your PC then you were paying for TSS to show up on-site at your home to fix it. Apparently this was better than regional central repair hubs.
Let me tell you, there were some seriously crazy stories from the front line. Most of our work was through Sears for Packard Bell (cheapest machines sell higher volume and therefore require the most service, not even counting for PB's lower quality). We serviced Acer, Sony Vaio, Gateway, Dell, and other brands, and did other point-of-sale and other contract work. I remember servicing the Gateway Destination system - that 35" CRT was huge for even a TV at that time. But being up close I realized it actually kinda sucked to use as a computer monitor. People tried to set them up in their living rooms, so imagine using your computer in the living room instead of an office, and required sitting next to the 35" display meant you saw the CRT up close which just meant the low resolution was blown up larger and you could see the physically larger pixels up close.
So yea, showing up to peoples houses meant going to a lot of random peoples houses which was mostly fine, but occasionally terrible. I had multiple instances of working on computers in a house having brownouts. "So wait, the computer reboots when the lights in the house flicker? And dispatch has sent me out with a new display for you... yea, you're gonna have to get the power company out here...". One time, I was sent to a house that was barely a shack in the woods. Main room had a light bulb hanging from the ceiling. That call in particular stands out in my mind, nice people, a 70 year skinny old dude in overalls and a 400' bearded lady in a shack. I couldn't do anything to make their Gatway machine work better as it was the power lines (lightbulb was visibly flickering the whole time I was there, that poor PC never stood a chance), so I showed her how to play her music CD's in PC (between power sags that crashed the machine) and she was tickled pink. One of my trainers had a couple horror stories: one dudes house was an underground bunker. My coworker was sent to replace a modem. After, the client couldn't find his Solitaire on his desktop, so he locked the door and demanded my coworker fix his Solitaire game before he could leave. My coworker obviously had nothing to do with that issue, but he recreated the shortcut to the desktop and was set free.
Eventually I jumped ship from TSS to IBM proper, it was a fun adventure. But that year and a half slinging in-home service calls in the evenings was an interesting time.
