These days I do:
Apple II, II+, //e, //c, //c+, //e Platinum, IIgs
TRS-80 Pocket Computer 1, 2, and 4.
TI-59 Programmable Calculator
Gateway 80486 DX2-50
All of my original Apple II gear from both the 70's and 80's is operational. And it has seen nearly daily use from the late-70's through the mid-90's! I've only had to replace a couple of the infamous Micron RAM chips in the II+ and //e.
Of special note are the Disk II drives. When I was a kid I'd yank them by the cable, throw them in my RadioFlyer, and BMX across the neighborhood to WaReZ Conferences. And when I got older I'd toss them in the old Chevy's trunk without a care. The only protection they had was a cardboard box to protect the finish and keep them looking like new. And a plastic baggie for when riding in the rain or snow. There were times I'd blast around the corner and the wagon would tip over spilling everything.
These drives would do all-evening copy sessions, a full-time BBS, and whatever else a shit-faced kid would do with them. Saving and loading hi-res pics (especially porno stuff) was a fun thing to do. And that meant a lot of disk access, as well as cracking and programming.
I've adjusted the speed on occasion over the years for bit-copying certain disks, and either changed, cleaned, or fluffed the pressure pad once or twice. Did a couple of head cleaning runs with the white cleaning disks.. All Apple approved PM for high-usage drives. These are all basic 5-minute ops and well documented operations.
Recently I ran some electronic tolerance testing and diagnostics. Mainly to practice skills and go through the procedures of the day. And to check out some newly acquired official Apple service disks for alignment. Everything was well within spec and therefore no adjustments were necessary. I fully trust them today. Disappointingly reliable.. What am I going to do for excitement? Will these damned things break already so I can have a Sunday repair project?!?!
This reliability extends to the interface cards, the monitors, the Sony TV sets, the T.G. Products hand controllers and joysticks, and especially the EPSON MX-80 printer. Not only were the Apple computer consoles and drives rock solid, so were the peripherals and accessories. Both Apple and non-Apple alike.
I've had little to repair on the Pocket Computers, and most all of it was for the printer, like change the rechargeable batteries, replace the ink ribbon.. Otherwise SOLID!
The TI-59 is reliable too. No problems there. Maybe it could use a rubber roller in time..? New battery? Yes.
I've had no issues with my DX2/50 from Gateway, it is built very similar to the IBM PC and weighs like 30 pounds. No issues with the computer. The CrystalScan monitor is totally dead and needs a thorough re-capping job.
Had an Atari 400 & 800, along with the 810 drive. I found the 810 to be acceptable. Toward the end it was starting to require you to flap the door to get a good load going. But the Computers themselves had no problems.
The 1541 for my C-64 was just terrible. Couldn't ever depend on it for anything.
Before I threw out my Amiga 500, the drive was going bad, too, and you had to eject and re-insert the disk several times to keep it going.
Had an Astrocade that wouldn't power up anymore, black screen, threw it away too.
