    Apple "Dot Matrix Printer" variants?

    I have an Apple Dot Matrix Printer model #A2M0058 that looks like this: I recently noticed that there are also apparently printers with the same name and model # that look like this: The only obvious difference seems to be the smaller logo that's been attached to the front of the case...

    accelerator silliness

    I just picked up this wonderful thing at VCFMW from @zigzagjoe Time for some shenanigans before doing something more practical with it... The Carrera CP allows on-the-fly switching between the Carrera and the DiiMO...

    recreating my first PC build

    In late 1998 I was 15 and I built my first PC...not my first computer, but the first one I built from scratch. Over the last year I've been gathering the same components I used back then with the intent of recreating it. The original specs were: Soyo SY-5EMA+ motherboard with 1MB L2 cache...

    SE/30 reloaded no bus activity

    I'm putting together another SE/30 reloaded and populated it to the point where it should chime. However, I'm getting absolutely no activity on the address bus when scoped at the CPU. The symptoms are a simasimac image and no chime of any kind because the CPU isn't walking the address bus and...

    tinkering with compacts all winter?

    Looks like I will be :) I recently discovered that another forum member lives less than an hour away and needed to downsize their collection. After making a carefully prepared and well researched presentation to my wife, she gave me the green light to go pick these up: There's a 128k, 512k...

    RGBtoHDMI fun

    After finding external video adapters in both my Classic and SE, I've been wanting to build an RGBtoHDMI. Well, I finally got my hands on a Pi Zero and all the other parts, printed a case, and assembled one. @Mu0n 's stickied thread was a big help. My 030 Classic came to me with this...

    MacTilt

    Was looking for something in the basement today and forgot I had this. Anyone used one before? Is it stable or is it as precarious as pictures make it look? Suppose I should put it under my SE and find out :)

    Is this IIgs board a ROM0 that was upgraded?

    I've had a IIgs "Woz" edition for awhile, and I finally took it apart to recap and retrobrite. It's always reported ROM1 when booting, so I kind of assumed that someone had just put the Woz top on a non-Woz machine. However, when I got it apart, I noticed a few things: The logic board is the...

    Apple II SCSI hard drive questions

    Anyone have experience using SCSI hard drives with an Apple II? I have yet to ever use a hard drive of any kind with any of my Apple II's, so I have no clue where to start with that, but I found this CMS SCSI card in one of my IIgs's: I also have this CMS model SD30U external SCSI drive...

    my $10 estate sale find

    Wife and I went to an estate sale today and found a lot of neat 80's computing promotional materials and catalogs, books, and TRS-80 and Osborne software. I initially saw the Osborne and CP/M books in the bedroom (a little light bedtime reading?) and grabbed them because I own a couple...

    found this ADB switch...is it safe to use

    I just found this buried in a box: I know hotplugging ADB is generally frowned upon and has even damaged some boards. I wonder if this thing is safe to use, or if it would change ADB bus IDs and screwball my mouse settings or something?

    Radius Stage II Rocket in a IIci

    I finally replaced some corrosion-damaged ICs in my dad's old IIci, recapped the PSU and logic board, cleaned/lubed the floppy drive, and it booted right up. As you can see, he had some goodies installed: Front-to-back are a Daystar 040 accelerator, a Radius Stage II Rocket, a Radius...

    MicroMac Power Workstation

    I posted a picture of this on Discord and received a lot of questions and requests for pictures. Apparently it was questionable whether any of these ever actually existed. Well, at least one of them did :) I called my dad (original owner) to ask him what he remembered about it. He thinks...

    6100 won't chime with heatsink installed?

    I just finished recapping my 6100's logic board. I also removed the heatsink, applied new thermal paste, and reinstalled the heatsink. It booted fine before doing any of that, but wouldn't chime afterwards. I triple-checked all the new caps, and everything looked good. I then removed the...

    660AV battery bomb

    I guess the silver lining is this is the first system I've encountered with battery damage: The chassis is pretty much completely rusted-out. I cleaned up the logic board a bit with vinegar and isopropyl: The NuBus adapter had some damage as well. I scrubbed some of the corrosion off...

    Radius SpigotPro AV...help me identify this component

    I have a Radius SpigotPro AV card that was installed in a battery-bombed Quadra 660AV. The card looks OK except for a single oscillator who's casing is completely corroded: I'm trying to identify that oscillator so I can replace it. I tried removing the corrosion with no luck. The only...

    found this little guy...

    ...in a bunch of retro stuff I recently came into. I haven't tried it yet, and I never used one of these back in the day, but it sure is...cute.

    Osborne anyone?

    I'm thinking about going to Starbucks and plopping one of these down on a table amongst all the laptops and getting my WordStar on :) These both looked like the one on the left before I fixed them up:
