January 12, 2011 – TRS-80 Emulator in Javascript!

Peter Phillips has let me know that the TRS80GP Model III emulator has been ported to Javascript!

Code is provided which will allow anyone to put a TRS-80 Model III Emulator on their web page.

Creating a page with the emulator is as simple as this:

<!DOCTYPE html>
<html>
<head>
<script type="text/javascript" src="trsemu-1.4.js"></script>
<head>
<body
onload="trsEmu.screen('scrn').button('btn').perf('graph').focus();">
<div id="scrn">
<canvas width="512" height="384" style="background:black">
</canvas></div><br>
<div id="graph">
<canvas width="512" height="100" style="background:black">
</canvas></div><br>
<input type="button"id="btn" value="Run"
  onClick="trsEmu.run('toggle');">
<input type="button" value="Reset"
  onClick="trsEmu.run('reset');">
<body>
<html>

January 17, 2011 – Tandy Annual Report 1977

Thank you David Sutherland for winning the packet given out to attendees of the Beverly Hilton TRS-80 announcement in 1978. It contained the 1977 Tandy Annual Report, the first TRS-80 catalog, and a bunch of handouts.

David was nice enough to drop ship his eBay winnings to me first for scanning.

March 7, 2011 – eBay Auction

Just a heads up as to some eBay auctions I have currently listed (ending Mar 14, 2011 at 09:03:54 PDT):

  • TRS-80 Project Manager – Catalog Number 26-1580

March 27, 2011 – eBook Version of Priming the Pump

Theresa Welsh let me know that there is now an eBook version of the TRS-80 related book “Priming the Pump: How TRS-80 Enthusiasts Sparked the PC Revolution”. The announcement is as follows:

Priming the Pump: How TRS-80 Enthusiasts Sparked the PC Revolution, is in its second printing and we have just released it in two eBook formats: for the Kindle (sold by amazon.com) and for the Nook (sold by Barnes & Noble). These versions include illustrations in color (those that originally had color — some illustrations are original black & white photos, but we have many old magazine ads that are color, but appear in the printed book as black & white). The price for the ebook version is only $9.95.

Here are the links to where the ebook versions can be purchased:

Kindle version: http://www.amazon.com/dp/B004P8JNIS

People who don’t have an eReader can still view these versions by downloading the “Kindle for PC” app or the “Nook for PC” app available at amazon.com or barnesandnoble.com.

May 4, 2011 – TRS-80 Model III and 4 for FREE (Local Pickup Only)

A site visitor has a Model III and a Model 4 available (+ dust covers) for free for local pickup only in Natick, Massachusetts. When last used in July of 2009, the Model III worked perfectly, and the Model 4 worked other than drive :1 (although the individual did not attempt to determine why).

To avoid the standard problem of people emailing the individual to ask if they will ship, you are asked to contact me. I will pass on offers to pick up the computers. First come first served.

May 8, 2011 – WordPress Trouble and New Page

Now that I moved the NEWDOS/80 Manual to be on a non-Wordpress page (like I had to do with the individual magazine pages), I can add pages again. I guess I am hitting some kind of memory/size limit on WordPress.

Anyway, I thought it would be useful to put all the “TRS-80 For Free” listings on their own page, and so I did.

Also, David Cooper has been kind enough to convert the Disk Request Page to be usable for systems without a mailto: configuration. Thanks David!

June 1, 2011 – Updates to Matthew Reed’s DMK Utilities

For those of you tired of seeing endless numbers of scans, here is some big news.

As enthusiasts may know, Matthew Reed has been working on patching LDOS so that it can accept dates after 2012. A description of the problem and the technical solutions can be found at:

http://www.trs-80.org/ldos-and-ls-dos-2012-and-beyond/ for Part 1 – LDOS and LS-DOS: 2012 and Beyond

http://www.trs-80.org/ldos-and-ls-dos-2012-and-beyond-technical-information/ for Part 2 – LDOS and LS-DOS: 2012 and Beyond – Technical Info

http://www.trs-80.org/ldos-and-ls-dos-2012-and-beyond-a-solution/ for Part 3 – LDOS and LS-DOS: 2012 and Beyond – A Solution

Matthew has just released the new version of TRSTools, which includes the feature to automatically patch LS-DOS/LDOS boot disks to extend their file dating capability to 2079. No separate date conversion step is necessary. Just load the (non-write-protected) LDOS 5.3.1 or LS-DOS 6.3.1 boot disk into TRSTools and allow it to patch the disk when it asks. The LDOS patches don’t take up any additional disk space and didn’t require getting rid of any file passwords. The new TRSTOOLS also [1] improves recognition of all three MULTIDOS date formats, [2] fixes a problem with reading from a heavily fragmented Model III TRSDOS dsk, and [3] added an option in the file viewer to switch to a hexadecimal view.

Matthew has also released updated versions of TRSREAD and TRSWRITE that can handle the new extended dating format.


June 2, 2011 – Any C++ Programmers Out There?

If you are good at C++ and good at modifying someone else’s source code and knowledgable about the Catweasel, please read on …

… as many of you know, TRS-80 disks were never meant to hold data for 30+ years, and one of the things I do for people is read their disks into DMK images. Much of the time, people are trying to get their old documents and records off the disks, so getting the best possible read off the disks can mean the difference between a corrupt file or a good one.

To do the disk reading I have a dedicated system set up with a Catweasel, a floppy drive, DOS boot, and Tim Mann’s wonderful Catweasel utilities.

As any of you who have a Catweasel may know, Tim’s utilities allow for a command line option to give a specific number of retries for any track which reads with errors BUT it outputs the track as read on the LAST read rather than the track as read on the BEST read. You could have 19 reads of “9 good sectors, 1 bad sector” but if the 20th retry is “6 good sectors, 4 bad sectors” that is what you get, and 3 otherwise good sectors are lost (you can restart the process again, but it is all going to be a roulette game). Those sectors being good could easily mean the difference between a good file and a corrupted one.

The reason for this, however (and as Tim has previously told me), is that the Catweasel works only on a Track level, which is the rub.

I am wondering if anyone out there has the C++ know how to modify Tim’s CW2DMK.c program so that when a track is read (as currently written in the program), an array is populated with the actual sectors (which I guess might be one entry for any DMK header, and the remaining array equal to the track length divided by the sector size; but what do I know), and then if a successive retry produces a good sector where there was previously a bad one, the (bad) sector in the array is replaced with the newly successfully read one; and once the retry count is done, the array is assembled into a track; at which point the track is written out (as currently written in the program).

Tim has been busy with other projects (he has been well aware of the request for quite some time), and the track vs. sector nature of the Catweasel probably makes this a project he does not wish to tackle, but a recent set of disks where the person was desperate for their data has just triggered me to see if anyone out there can do it. Modifying the source code appears, on my quick read, to be permitted under the license under which it was issued, provided certain obligations are met.

However, it is Tim’s project, Tim’s source, and whether this is actually made public should be entirely up to Tim in my book. Certainly anyone who writes in the functionality is encouraged to send it to Tim; perhaps he will integrate it.

Links:

  • http://www.tim-mann.org/catweasel.html – Tim’s Catweasel Page (with links to v4.4; source code is included)
  • The DMK format is explained at the bottom.
  • The FREE MSDOS C++ compiler which is used to compile the Catweasel utilities is the DJGPP Compiler (http://www.delorie.com/djgpp/). Tim’s makefile is makefile.dj for that reason.

Larry Kraemer has developed some step-by-step tutorials on how to run David Keil’s DOS Emulators and Tim Mann’s XTRS Emulator under Debian and Ubuntu. As of December 2019 it is almost all incorrect so the link has been removed.


July 13, 2011 – Emulator Updates

George Phillips has updated his GP2000 TRS-80 Model I/III/4 Emulator to v1.8. Changes include:

  • Works on displays whos width is not a multiple of 4.
  • Recording in Flash video format (.flv).
  • Supports Model 4 with hi-res graphics adapter.
  • Debugger improved.
  • Z-80 profiling has legend and branch taken percentages.
  • HALT instruction now emulated properly.
  • Model I double-wide video.
  • Added “-time emulation” option to show CPU emulation time.

Stephen James Hurd and Ken Pettit have updated their Model 100 emulator, Virtual T, to v1.5. The update can be downloaded from the emulator page.

David Keil’s site appears to have gone down. Since that site was the only source of David’s emulators (and also because David’s emulators were entirely incompatible with Windows XP or LCD monitors since Dave chose to use direct hardware writes for screen updates) references to David’s emulators on the emulator page have been removed.
