SAMS Computer facts: Epson QX-10

I also got this cool thing in the mail yesterday, which has a great deal of technical information and schematics of the various bits of the QX-10. For posterity, the various parts of this are archived here (not yet OCRed): Cover Preliminary service checks System (CPU, keyboard, power supply) Disk […]

Writing drivers

I started piling some of my imaged disks onto a big ProDOS volume for use with Virtual ][, using Glen Bredon’s DOS.MASTER, since nearly everything I’d ever done was in DOS 3.3. In the process, I came across an old text file I’d written called “Writing Drivers“. Click the link […]


After setting up the Epson QX-10 and finding that, although it happily displayed “INSERT DISKETTE” on its monitor, it didn’t recognize any of the diskettes I inserted in response, I decided to pull it open quickly and take a look to see if anything presented itself as an obvious problem. […]

I may never buy software again

Today in my office, an actual Epson QX-10 arrived. I’d put an ad here to help explain what the QX-10 is, but no ad can do it justice. Though, as it happens, all I can get the machine to do at the moment is tell me “INSERT DISKETTE”. I have […]


This isn’t right. The drive I’ve got hooked up to my Kryoflux produced this little marvel today. Guess there’s not much hope of retrieving whatever it was that was on that disk. Also, I think I’d better disassemble that drive and figure out what’s happening before any more disks are […]

More SE/30s

I got a couple more SE/30s from somebody’s garage recently, both of which externally look a bit nicer than the first (recent) SE/30 I got. One was assembled in Ireland, and one was assembled in Singapore. I don’t at the moment know what the difference would be. Maybe the Ireland […]

Subliminal Apple branding

Including Apple stickers with computers and other hardware was always kind of a goofy, childish thing, but I think it worked. People used them, people stuck them to their folders in school, to their file cabinets, very often (kind of superfluously) to their computers or disk drives. Mine, for some […]

Some stubborn goop

I spent a little while going after “the freakish horrorshow that lives under the keyboard” of my childhood Apple ][+, and I have two comments. First: to the extent that I’ve managed to lift it off, it appears at least as if the PCB below is undamaged. Second: that is […]

A longer list than I’d realized

There are still a couple of things that I’ve gotten that haven’t been documented here yet. They’ll get more discussion later on. This is really mostly a list with pictures. I now have a Macintosh LC II, which has the notable property that it can host the Apple IIe emulator […]

No video. $10. Final sale.

I went to my first computer recycler today. I’d written some email to a few of them, one wrote back quickly saying that they didn’t have a lot of old Apple stuff, and that it changes day to day, but that said at the moment they had “some old laptops […]
