Second channel: Preserving the ROMs on the best RAM tester ever made

Added 2025-08-04 18:05:09 +0000 UTC

Hello my patrons! Ah it's Monday and I'm trying to get through my insanely long to-do list. It's funny how it's nearly lunchtime and I've haven't done anything when it comes to making videos. If only I had multiple copies of me, so I could focus on making videos and editing -- and less on other stuff. Anyway, here's the next video in the queue for release on the second channel. It came out of an email from a viewer who also has one of these RAMCheck devices and was hoping I could dump the ROMs on this one so we could upgrade his. It seems nothing is really preserved for these devices, so I decided to document a little about how this thing is designed, dump the ROM code and try to dump the GAL that is part of the firmware.

I end up spending a chunk of my time making sure to preserve data (ROMs, manuals, etc.) that I find like this. It's something I'm trying to do with the Zenith ZT-1 as well. Who knows if anyone will ever need this information again, but at least it's hopefully saved for that one person who does need it. :-)

Thanks for all the support and I think it's time for me to get back downstairs and working on the next videos!

Thanks for all your support!
