At least, only half functioned when they arrived. This particular machine is a bit of an annoying one to work on and one that has defeated some loftier heads than mine. Well, perhaps not quite defeated, but definitely not the most successful. (I still kind of wonder what happened to that machine …) https://chrissalch.com/posts/tandy-1110hd-battery-replacement/ Sun, 04 Aug 2024 12:17:31 -0500 https://chrissalch.com/posts/tandy-1110hd-battery-replacement/ Old Batteries It’s been a while since the last time I worked on my Tandy 1110hd partly because of normal life and partly because I’ve been playing around with another project. I was able to get my hands on a pair of Compaq Portables in reasonably decent shape. Thankfully, both units powered on (classic buy two in questionable condition to make one working unit) and neither has suffered the exploding tantalum plague so I got lucky again. https://chrissalch.com/posts/tandy-1110hd-bios-spelunking-part2/ Sun, 30 Jun 2024 12:17:31 -0500 https://chrissalch.com/posts/tandy-1110hd-bios-spelunking-part2/ Where We Left Off We left of with my initial failure to get an XTA2SD card working in the Tandy 1110HD. I did get the Gotek functioning though so we had a means of booting the machine. So at least I knew that the motherboard appeared to be ok. No leaking caps, no blown fuses, just a dead floppy drive, dead battery, and no hard drive. Since then, I’ve made a few quality of life hardware changes that almost let me put the machine back together. https://chrissalch.com/posts/tandy-1110hd-bios-spelunking/ Thu, 30 May 2024 10:15:04 -0500 https://chrissalch.com/posts/tandy-1110hd-bios-spelunking/ The Tandy 1110HD I recently came into possession of an old Tandy 1110HD Laptop, a early 90s era machine with a V.20 cpu, the classic 640k of RAM, a CGA class monochrome reflective LCD display, 720k floppy drive, and a 20mb Conner CP-2024 hard drive. I grew up around a Radio Shack franchise and actually had one of these machines a very long time ago. I’m reasonably comfortable around a soldering iron and test equipment so when I found a couple of these being sold for parts on Ebay, I decided what the heck and picked them both up. https://chrissalch.com/posts/new-toys/ Sat, 22 Jan 2022 10:15:04 -0500 https://chrissalch.com/posts/new-toys/ I’ve finally gone and bitten the 3d printing bullet and of course, I’ve jumped off the deep end into resin or SLA printing instead of going with FDM printing. Resin printing is a bit more daunting, and definitely has it’s limitations over FDM (build volume, post processing complexity, mess, etc.), but I think the advantages will ultimately out weigh all that for what I want. Which is the ability to print small, reasonably detailed things that are strong in almost every direction. https://chrissalch.com/posts/new-blog/ Sun, 04 Oct 2020 10:15:04 -0500 https://chrissalch.com/posts/new-blog/ What can I say? It was time for a change… And it had been years since the last time I posted anything on this site. So, here it is! The new blog that doesn’t have a monstrous PHP application like Wordpress (Nothing against them, I just didn’t want to keep maintaining an install) under the hood. No, this site has delved deeper into the realms of modern ways of doing things and gone full on enterprisey application deployment processes.
