TRS-80 Model 16B - 8 MB RAM Upgrade - Part I: Build TJBChris 2023-02-02 | My TRS-80 Model 16B could use more 68000-side RAM for XENIX. A group of former Tandy engineers called Tandy Emeritus has designed a 3-bit MMU board and companion 8 MB SRAM board for these systems for just that purpose. These boards are not generally available for sale. If you wish to contact Tandy Emeritus members for availability, join the Tandy Discord server. For part one, let's build the boards and talk about next steps!This video is more akin to my older ones with lots of time-lapse/music. These projects are a lot of work, and take a lot of patience and time. That's hard to convey if I gloss over it...as it is only about 60% of the footage made it into the video.And for some reason, I kept saying SRAM card while referring to the MMU board mid-video. I don't know what was wrong with me that day.

BIG-ly Tandy Part V: Running Teleterm From A Real Disk TJBChris 2022-09-29 | The fifth and final video in my #SEPTandy series, BIG-ly Tandy. Using my TRS-80 Model 16B, I connect the (recently-restored) 8-inch floppy drive and make real disk copies of today's application: Teleterm. Then, we boot from my real disk and explore a little of Teleterm's functionality including the terminal, text editor, and terminal emulation editor. Using Terminal, I connect to FozzTexx's Level29 BBS and print a portion of my session.Update - Around 9 minutes in, I mention the orientation of the label when inserting a disk, incorrectly stating the diskettes are why the label must face the operator. I meant to say big Tandy machines other than the Model II require the label to face the operator.Level29 BBS Website: bbs.retrobattlestations.comParticles BBS Website: http://www.particles.org/particlesbbsCheck out the catalog entries for these systems here:radioshackcatalogs.comOther links:TRS-80 Model II Archive: github.com/pski/model2archiveRadioShack Catalogs: radioshackcatalogs.comThe Color Computer Archive: colorcomputerarchive.comChapters:Intro (0:00)About The 8" Floppy Drive & Disks (0:27)Machine Apart / Working w/ The Drive / First Format (2:03)Back-up to Diskette And First Disk Boot TRSDOS-II (4:22)Booting The Teleterm Disk / Looking at the STARTUP file (6:56)Starting The Teleterm Application (9:43)Exploring The Menu System / Configuration (11:40)Adding A Phone Number To A Profile (16:09)Connecting to Level29 / Loggin In (19:20)Moving Around In Level29 (20:54)Printing Our Session (21:45)Looking At The Games List / Logging Off (23:27)Checking Out The Teleterm Editor (24:29)Exiting Teleterm and Proper Shutdown (26:31)A Look At The Printout (27:52)Series Wrap-Up / What's Next (28:39)The Thank You Part / You're Gettin' Me For Free (30:22)Outro (32:02)I do these videos unscripted, so I apologize if the in-the-moment descriptions of things are a bit scattered.

Each application has its own section: Text, Worksheet, Filer, Calendar, Mail, as well as the many DeskMate accessories. This video is very long as the sample session is comprehensive.

Tandy 4825 SX - CD-ROM Drive Replacement - Everything Goes Wrong TJBChris 2022-03-23 | Watch everything go wrong as my Tandy 4825 SX gets a new IDE CD-ROM drive to replace the failed 2X Creative drive.

TRS-80 Model 16B - Overview And Restoration - Part I TJBChris 2021-12-16 | I just picked up a TRS-80 Model 16B!

Unfortunately it was damaged in shipping, causing considerable damage to the case. In this video I cover the damage to the system, attempt to it, and test out the results of my work.This video is a bit longer as repair was a multi-day process and quite involved.

Boat Burning I - Cargo Ship TJBChris 2021-10-19 | We built a model boat...and burned it! As you can see, things didn't go as well as planned; I had to help it along a couple of times. See just how well (or badly) burining model boats can be. We have two more boats to burn, so stay tuned!As you can tell, I'm experimenting with the format of these videos and the process for getting the best result. I'll be applying what I've learned while burning this boat to future burn videos.

Bloopers and Outtakes I TJBChris 2021-09-28 | ** EXPLICIT LANGUAGE ** This video contains explicit language. And some suggestive dialogue. You have been warned.Here are some behind-the-scenes outtakes, bloopers, and other general wackiness that happens when I do my videos. I often stumble over words, fart unexpectedly, and get annoyed at myself as I'm working through a presentation. Enjoy!This video is an "After Dark" video because it contains ADULT LANGUAGE and CRUDE HUMOR. You have been warned. If this isn't your particular brand of content, I'd invite you to take the advice of the late George Carlin and "change the channel". At least for this video. Then come back later for more great retro-computing goodness!Comments are disabled for this video.
