SocketwenchWell, the <a href="https://masto.hackers.town/tags/trs80" class="mention hashtag" rel="nofollow noopener" target="_blank">#trs80</a> model100 has a clock going into CLK on the 80C85, but all the address and data pins are all high. Doesn't look like it's stuck at reset, though?

SocketwenchWell. That's weird. I'm getting this odd pattern no matter where I probe the TRS-80 m100 board. Brain is telling me, "You need to ground your scope probe, you idiot," but I'm scared I'll blow something up.<a href="https://masto.hackers.town/tags/trs80" class="mention hashtag" rel="nofollow noopener" target="_blank">#trs80</a>

Leaded SolderNew blog post! I'm tired of my TRS-80 Colour Computer needing an old school RF connection to get video out.

Willard GooseyThere's an ebay guy that sells scans of technical manuals. He had the PC4 Sevice Manual. So I got a copy.Not a lot to the manual, these things weren't really going to be repairable with 198X equipment.This manual also covers the matching cassette interface, though, and I was interested in that. Hoped the interface was just some caps and resistors, but nope there's a whole IO chip in there.

Spike :donor:Hey there, fellow retro-tech nerds! The <a href="https://post.lurk.org/@mediaarchaeologylab" class="u-url mention" rel="nofollow noopener" target="_blank">@mediaarchaeologylab</a> has posted its open call for practitioners-in-residence in the lab for the next season, which begins in September. Submit your proposal by May 15! Please boost for reach.<a href="https://mediaarchaeologylab.ghost.io/practitioner-in-residence-open-call/" rel="nofollow noopener" translate="no" target="_blank">https://mediaarchaeologylab.ghost.io/practitioner-in-residence-open-call/</a>The theme for the 2025/2026 residency is Counter Computing: Alternative Imaginaries. Lab director Lori Emerson describes it this way: "We are interested in any form of artistic and/or scholarly practice that engages counter-computational practices, such as glitching, hacking, tinkering, queering, subverting, (un)making and (re)imagining. Through such experimentation, we encourage you to explore how our relation to (and imagination of) technology can be remade to envision alternative pasts, presents and futures."The lab is asking interested parties to submit a proposal for an up-to-4-week residency that includes full access to the lab and its resources, and logistical support. Residents are expected to produce a public lecture, demo, video, performance, or exhibition as part of the residency.
