Your eye sight is better than mine! Thanks.

I couldn't tell which way was right, but did originally have it the other way. I hope it didn't damage the circuit either!

Thanks for the help. I can't quite tell what type of RTC it is. But I did try adjusting the dip switches again, with no luck. Just the same 101 error. I'm guessing it's probably just broke, but luckily the rest of it works okay.

This is helpful, thanks for doing this!

I bet this is the problem -- I did see these settings on Stason, but as I re-review it now, I see my brain assumed SW1 was on the left side and SW2 on the right, but it's actually reversed. Looks like I flipped the wrong switch. I'll try it again this weekend when I have some time to play with...

Thanks. I gave it a try, but get a msg 101 (Clock hardware isn't working) message. Do you think the problem is the battery, or something else?

Just curious if anyone knows what type of battery this board takes? Looks like a 2032.

The monitor/CRT is no longer turning on (blank screen) on my old Mac 512k. I have no idea how to troubleshoot or repair it. I can't seem to find a repair service online. Is this something my local electronics repair shop could do? Are there people here who offer such services? Thanks in...

I currently have a 1.2mb floppy inside my IBM XT, but as you're probably aware, there are inconvenient compatibility issues with 360K floppies. And since the other bays are already occupied, I'd like to get an External 360K Floppy Drive for it, but I'm not sure which one to get. At least, I'm...

Does anyone remember when these floppy disks were made/sold? There's no copyright on it, but one of the labels on the side say it is for the PS/2 computer, which I'm thinking places this around 1987-1993. I don't recall seeing these sold in stores back in the day, and find it interesting that...

I know this sounds crazy but... A neighborhood lady asked if anyone wanted her old 3.5" floppies. I scooped them up! I took them home and started with my USB floppy drive. Here's what I did: I inserted some of MY floppies first, and it works (like it always has). I inserted one of HER...

I've noticed the AST SixPack Plus and MegaPlus II come up for sale from time to time, and on the surface, they appear to provide much of the same functionality. They were even made around the same time. My question is, does anyone know what specifically were different about these 2 add-on...

I managed to get one of the elusive 5154's on eBay, but as it often happens, it arrived damaged, with no love from the seller. I haven't tried to turn it on yet, so I'm not sure if the CRT itself is bad, however, there was some cosmetic damage to the corners, and the CRT has recessed into the...

Hello, I'm in need of the original software/drivers that went with the Microsoft Mach 20 286/287 Accelerator card (specifically mach20.sys, m20cache.com, etc). There were actually 2 disks that came with it, but one of them went bad on me. Can anyone help? Thanks!

Looking to buy the infamous Zenith Eazy PC (I think these are mostly circa late 80s). I'm specifically looking for the model that has the hard drive. These things are getting hard to find! Thanks.
