April 17, 2019 – New TRS-80 Trash Talk Podcast

The podcast TRS-80 Trash Talk # 30 is out now.

In this episode, In this episode, Spring is in the air at Trash Talk headquarters, so we’ve been itchy to make quite a few acquisitions lately that we discuss, including a long weekend drive to Chicago. We also introduce a new TRS-80 search engine that should prove to be a highly valuable resource to the TRS-80 community. Then, we do some eBay shopping for TRS-80 computers and related items. Finally, we interview TRS-80 programmer Rick Papo. Rick was the author of several important reference books for the TRS-80 which included reverse engineered and highly documented system source code. These are invaluable references for the modern day Z80 assembler programmer..

I continue to try to add ads for files in the archive and missing entries for files which are missing. Unfortunately, this Sourcebook lists the vendor who submitted the item and price as the contact information instead of identifying the actual author of the program; making using it for these purposes impossible. I’ll continue going through magazines …

March 8, 2019 – Site Update

I finally bypassed the bug that was keeping product advertisements from showing up when clicked on the Software search results. I am now going through all the catalogs I have, and am trying to add as many ads/catalog entries as I can. This includes a foree into listing items which are missing from the archive.

February 14, 2019 – TRS-80 Network Interface Card

Peter Cetinski has been working on a project that provides a simple, cheap, WiFi based, encrypted Internet communications via the TRS-80 by connecting to the Model III and Model 4 expansion port.

TRSNIC provides the foundational protocols required to implement modern network interactions on the TRS-80 microcomputer. The first such protocol provided is TCP/IP via an implementation of the Berekely Sockets API. TCP/IP is the dominant low level network protocol in use today. Many of today’s higher level network protocols like HTTP and FTP are implemented on top of TCP/IP. This means many modern networking applications and systems can be built upon the base TCP/IP support provided by trsnic.

You can read more about it a here and here.

January 24, 2019 – TRS-80 Add-Ons

Joe Rounceville has been designing and building peripherals for the Model I which he wants to share with everyone.

First is TRS80HDD. It is a way to run TRS-80 Model I disks from a SD card. Similar to a MISE but far less sophisticated. Schematics, instructions, and background can be found on his GitHub repository https://github.com/calphool/TRS80HDD. He advises that all parts are currently attainable at Mouser Electronics, the edge adapter from DigiKey, and the schematics can be sent to allpcb.com for creation of a PCB.

Second is TRS80GS. It is an expander for a TRS-80 Model that includes Texas Instruments video and audio chips to permit the Model I to do color graphics and have 6 tonal voices and 2 drum voices. It also supports Atari/Commodore joysticks. Schematics, instructions, and background can be found on his GitHub repository https://github.com/calphool/TRS80GS.

Thanks for keeping the TRS-80 alive, Joe!

January 10, 2019 – TRS-80 Manuals and Magazines – Free for local pickup or the cost of Packing/Shipping

Update: CLAIMED

A site visitor located in New Braunfels, Texas (central Texas, between Austin and San Antonio), has a bunch of magazines and original manuals to give away to a good home. Free for local pickup and he is willing to ship if you pay the cost of packing and shipping.

I will relay messages sent to me in the order received. First come first served.

Model 3 or 4 USB Keyboard

Kyle Wadsten has released his interface boards for the Model 3 and 4 that allow plugging in modern keyboards into the classic TRS-80 Model 3 & 4 machines.

There are two different board designs, one for USB keyboards and another for PS/2 input. 

What I find very intriguing and helpful is the ability to use the existing keyboard along with a modern keyboard at the same time.

Check out more at his order page or on the Facebook announcement page at the links below:

Kyle Wadsten’s NEWKEY/80 Arduino and custom board allow for a modern keyboards on your Model 3 & IV machines.
