Of Davis California? They at one time made several TRS-80 products. There is a link of google but it takes you to DIGI....wonder if same folks?

Everyone wanting a digital copy has this? Opened an old box packed away in 1992. I am sure it's been digitized but I don't have time search it out

Maybe...... Over last couple years or so we have had problems getting Zilog latest chips Older Z80 design chips were available but not newer latest technology from Zilog. Watching news Zilog has now been labeled as a country still selling to and supporting Russia. PBS showed file of a...

I have been asked to make a version of TRS-OS & it's guest LSDOS for Argon computer. I am posting here to see if any programmers with knowledge of Argon low level API for video/keyboard would be interested in having a discussion about this port? I don't want to reinvent wheel so a port to...

Hey I have the registered TRS32 emulator and am wondering if anyone else has had an issue with using mouse. It is seldom but when using emulator i sometimes lose control of mouse pointer and it jumps to upper right corner of screen and stays there. Only way I can get control of PC back is using...

I am trying to recreate my copy of LS HOST/TERM 6 for model 4. I have manuals and all but 2 files. This product was in Misosys 1992 catalog. I have scanned manual already but missing term6 & host6. Once I recreate originals Tim Mann said he would post to his website. At this time he does not...

I am sure many old salts on this forum have already seen this but for newbies like me, It was just another video for me until I seen a dude issuing voice commands to a Model I. He was using a mic that looked like it belonged to a car in one Adam 12. I don’t guess that is so impressive but...

I have several 4P of various stages of disrepair, some model 4 desktop in different stages of disrepair. Things are dusty, dirty or both. I would like to get rid of this in one lot. Will meet somewhere if interested. I am in southeast Ohio. I had one XLR8 MANY people have asked to buy...

Regarding my efforts to execute TRSDOS SYS1-13 on newer hardware. update......it works on eZ80 now. I refer to my project as TRS-OS. Booted TRS-OS using eZ80 @ 50mhz no wait states. Using memdisk drives and 50 MHz clock it's screaming fast. Testing out things that will and will not work...

Please give me the 30k ft version of what collectors have today. As I understand RS used Xenix on these models as well as TRSDOS. I see lots of projects going on for these bigger machines and am wondering if you have source for Xenis or working from object/executables only? And second part of...

Can anyone tell me how to write a SSDD 180k system diskette (TRSDOS 6.x standard boot diskette) to a file? I want this file to be T=0 s=0 is first record, t=0 s=1 is next record etc. An exact byte for byte image of 180k floppy. I thought I had found my answer with DiskDisk that allowed you to...

Only thing I can find on internet is VOL 1, says VOL 2 & 3 not available. Am I all wet and not looking in right place? If 2 & 3 not available, is there a reason (i.e Soltoff did not release for public) or is it just lost to history? Thanks

Systems Engineering Laboratories (also called SEL) Read legacy mag real to real tapes.

PM me if you need a copy.

I need copies of RS compilers for FORTRAN & COBOL if anyone has them please. I am interested in model 4 versions only. Thanks

I am writing a RAM disk driver and have been researching a question I had while working on this project. Looking at legacy drivers creating RAM disks on TRSDOS 6 each of them requires their own format program. I am curious about that. To me if you (or me) were developing a RAM disk driver, we...

I noticed Tim Mann website says source vol 2 and 3 not available. Do folks already have this or should I scan mine into a PDF? Thanks

As I am collecting all my TRS80 stuff in one place for a final sale I just found something that may interest others. When I had a shop and worked closely with local RS repair center they gave me my own official models 1/3/4 diagnostic disk. It has its own OS sort of, what I mean is you do not...

I know answer to my question in title, but sometimes to make a statement it is best to pose it as a question. I have a statement as to why it is important to remember in historic content why key is there. There is one VERY rare piece of TRS80 hardware, if it even exists at all today that ties...
