Bonus May: my most difficult reverse engineering task this year was the IBM MCGA graphics chipset. tens of thousands of transistors. whew!https://mastodon.social/@tubetime/114605553903880611

Also in August, a new book came out--I somehow found the time to be the technical editor for it. it's great, you should go read it.https://mastodon.social/@tubetime/114989988735356677

in November i reverse engineered a bunch of disposable vapes and put the designs online. they're quite hackable!https://mastodon.social/@tubetime/115555385897273188

and, wrapping up 2025, this December i've been reverse engineering the HP 16717 logic analyzer card. they tend to get corroded and they're hard to repair, so this should help folks out.https://mastodon.social/@tubetime/115741254454906195

that about wraps up the highlights. there's a lot more if you go through my Mastodon (and Bsky) backlog.on to 2026! wishing you all a happy new year 🎆

@jhhl you kind of answered your own question. this is the BCD that is the predecessor to E"BCD"IC since that is what the 1401 uses.

it's been sitting fallow for quite some time, and is definitely not perfect, but i figure someone could use it. there's a lot of room for improvements!
