Hi guys/gals, The list archive now goes back to 1999. http://dir.gmane.org/gmane.comp.hardware.trs80.model100 I don't think the index is fully built out yet (so searching for TPDD will only bring up recent articles at the moment) but that should happen automatically, eventually.

Setting up a TPDD

Keith Johnson — 2008-06-21T03:49:43

Hello Guys, I'm a long time lurker, 1st time poster. I bought my 102 a few years back and a model 200 more recently. I'm only 25 but I remember see one on Discovery Channel in the late 80's or early 90's and I wanted one. So now I have two. It sat on my shelf for a long time. Well just the other day I got a TPDD. Eject mechanism hadn't been used in a long time and was stuck but I managed to fix that. My question is how can I test the drive to see if it works? I see I need a file call FLOPPY.CO and that I would need to boot off the disk. Where can I find this file and how to I get it onto the disk. Can I take a regular FAT formated disk and just copy it. I doubt it is that easy. Or is there a image out there I can just use "dd" to blow on to a floppy. Thanks ahead of time guys. Keith Johnson The Catskill, New York.

while I'm on the topic..

Stephen Adolph — 2008-06-20T02:30:47

way off topic, however... one of my favorite videos. http://www.youtube.com/watch?v=Y1gcvHBd7oc have to share this video. Here is the background info. A few years back sailboat design really took off, literally. The combination of carbon fibre for high strength in both hulls and masts, and a new idea called the "canting keel" has created some incredible performance on the water. I know most people are not sailors, however I hope it's interesting. There is a round-the-world race sponsored by Volvo, and the current class being raced is called the volvo open 70. These boats are capable of >40 knots under sail in the open ocean. This video focusses on one of the boats "pirates of the caribbean" as it pulls out of south australia and heads out into the southern ocean (the roaring 40's). I find it interesting to watch a 70 foot sailboat surfing at 40 knots in 10 to 20 foot seas, although I am sure I would not be up for the ride. 1 month of constant firehose in the face....no thanks.

my vacuum controller project

Stephen Adolph — 2008-06-20T01:21:29

Well, almost done. It's up and working now, and I had loads of fun in the process. To use the M100 as a controller, as I've mentioned I'm using the BCR port to power a vacuum sensor, and take the readings. Originally thought to use the printer STROBE signal as an output, but that does not work. I changed the plan to use the casette port relay instead, and that works great. I used an old modem cable to connect to the cassette port, and to make the specific wiring I needed. The casette relay drives a signal to an external relay board that has a relay capable of switching 120V 15A. That relay sends power to the vacuum pump. My 555 circuit to convert DC voltage from the automotive MAP sensor, to a frequency, worked well, however it is not linear. So, I had to use a lookup table to correct the non linearity of the sensor. The coding was so fast and easy...I'm surprised I did it. Usually I have a lot more pain. I had the M100 in the test set up, with a REX installed with TSDOS. I could compile assembly

Every Menu File Slot Consumed in M10x Laptop

Ron Wiesen — 2008-06-19T13:29:13

Field Day 2008 will be a bit different than my past Field Day efforts in one respect: I will operate on every HF band allowed by the Field Day rules, and I will employ every allowed mode of transmission. Consequently, in the particular M10x laptop that I'm dedicating to handling the logging chore, use of the "Log Recorder for Model 10x" will consume every menu file slot. It's an interesting "maxed-out menu" situation where the Model 10x has just enough file slots to meet the demand -- no file slot remains unused and no additional file slots are needed. As is the norm, the first 5 file slots are consumed by the built-in applications (BASIC, TEXT, TELCOM, ADDRSS, and SCHEDL). All of the remaining 19 menu file slots are consumed, as the menu depiction below illustrates. | BASIC TEXT TELCOM ADDRSS | | SCHEDL LOGREC.BA L160CW.DO L160DI.DO| | L160PH.DO L80CW.DO L80DI.DO L80PH.DO | | L40CW.DO L40DI.DO L40PH.DO L20CW.DO | | L20DI.DO L20PH.DO L15CW.DO L15DI.DO | | L15PH.DO L10CW.DO L10

Solstice Point - Summer in Northern Hemisphere/Winter in Southern Hemisphere

Ron Wiesen — 2008-06-13T20:10:31

According to calculations made by my Model 10x laptop, next week, at 23:59 UTC on June 20th, our planet reaches one of the two solstice points along its orbital path around our star. This particular soltice point marks the middle of Summer for folks living in the Northern hemisphere, and the middle of Winter for folks in the Southern hemisphere. Enjoy the season wherever you live, -= Ron Wiesen =-

Building VirtualT from CVS for Linux

John R. Hogerhuis — 2008-06-13T18:50:43

Just a reminder that COMPLETE instructions for getting via CVS and building the latest and greatest VirtualT under Linux are kept here: http://bitchin100.com/wiki/index.php?title=Building_VirtualT_on_Linux It's easy! Except when it isn't. And if it isn't we need to hear about it so we can fix the instructions or the build. BTW, you only need to build FLTK the first time. So keeping up with the latest-and-greatest only requires setting the FLTKDIR variable and: cvs update make

Toppling the Model T's stack

Gary Lee Phillips — 2008-06-11T18:03:03

OK, I've got a program that appears to work. I can find no sign that it's malfunctioning, yet after it has run a couple of times, other weird things seem to be happening. I'm wondering if I've unbalanced the stack. The symptoms only occur on a real M100 with Ultimate ROM-II installed, not on Virtual T with Cleuseau or UR-II. I even have both Oppedahl and Morgan sitting here, courtesy of the interlibrary loan service, but they aren't answering this question. In CP/M and in Model 4 LS-DOS, they told the application programmer how much stack was available when his program receives control. I seem to recall somewhere between eight and sixteen words were supposed to be available. On that basis, I have not bothered to provide my own stack, since my code has no recursion, no PUSH or POP instructions, and no CALLs nested deeper than one level. Is this too risky? Should I be saving the SP register and pointing it to a stack of my own just to be sure, then restoring it at the end before I return? I am calling ROM r

VirtualT and Cleuseau?

Gary Lee Phillips — 2008-06-11T10:48:02

Now established that my "trick" for getting the CP/M assembler to produce Model 100 .CO object files does work. There is no coding in assembly without debugging eventually, though, and I thought Cleuseau (ROM2) and VirtualT would be the easiest way to do that. Has anyone played with Cleuseau in VirtualT much? It does load and activate, but not all the commands work as documented, or so it seems. For instance, at the CMD> prompt (reached by issuing CALL911 in BASIC) the FILES command goes off into never-never land and requires a reset to recover. However, the .FILES command at the BASIC Ok prompt does work as documented, and gives the Cleuseau-formatted directory listing. There's a call that should generate a checksum of the ROM2 image, and that also goes off into its own world never to return. My assembly language "Hello world" code assembles correctly and runs correctly under Cleuseau when called from BASIC. But I can't get SAVEM to write the object code back out correctly. It seems to be putting wonky n

M10x, Terminal LF's question

John Whitton — 2008-06-11T01:43:42

Hmm, using Terminal, it does not generate a LF along with the CR when sending. I haven't perused every line of every manual..., but is there anywhere that LF's may be enabled? I doubt it, but maybe? Actually, I'm only concerned about *local* line feeds.., in half duplex mode. The problem is that the other end (when it responds) writes over (on the screen) whatever has been entered on the M10x. Ironically, this also means that when sending data (using Terminal) to *another* M10x, one can not input the received data (at the other M10x) using BASIC's Line Input..., which *requires* a CR + 0x00 (i.e., a character after the CR..., *any* character) to accept data.

Is it just me?

M H Stein — 2008-06-10T05:31:35

I'm curious: how many folks out there agree with Ron that negative addressing is "convenient, brief and clear" ? I'm afraid I don't see the point at all. Memory maps, system calls and functions like Ron's LOADM example generally use positive addresses that have to be converted, and I don't see any point to numbering memory locations in ascending order up to 32767 and then start counting back down to 1; how is 32700+100= -32736 more convenient, brief or clear than 32800? Nor do I see why it's better to number M/L program locations (lines) in descending order as you go up in the memory map when almost every numbered list of any kind is numbered in ascending order from top to bottom as you go down through the list (i.e. the END is usually the highest number, as it is with positive notation). I suppose it does save a few bytes as long as the addresses are in the top 1000, but other than that I only see drawbacks. What am I missing? Ron, did you learn your writing style from writing government repo

LaddieCon factoid

John R. Hogerhuis — 2008-01-01T05:42:32

Rick Hanson asked me why LaddieCon is named what it is... I knew there was a reason but couldn't immediately recall. I think that I just took DL (the initials for Desklink) and reversed them. Try to pronounce LD, you need some vowels thus, Laddie. Well you could say "Led" or "Leddie" but that would associate it in my mind with Huddie Ledbetter, or Led Zeppelin. Either way, LaddieCon is not worthy. The Con part means Console. My intent is to eventually write a nice GUI for it, but the current version is console only. So if I write the GUI version it will just be called Laddie. Well I won't "ramble on" any further.

m102 Remem

Michael P. Hamilton — 2007-12-30T22:34:07

I think you have an excellent idea, Steve! I agree also with the idea already mentioned of installing the new nicad button while you're at it, even if it adds a few bucks to the price, although I'd still like you to upgrade my two models before condidering an extra system here. I'm kinda' stuck without any extra room here, and most of my stuff is sitting in plastic tubs already since my move. It makes things rather inconvenient to get to when needed. I might have to spend some time re-learning the remem system before getting anything else (I've got all 3 model-t laptops here). Considering the price of a recent m200 with 72k ram, your units are quite likely to skyrocket in price. An excellent way to pay for your hobby!

Modern DVI replacement

Daryn Hanright — 2007-12-30T22:06:29

With all these ideas re: hardware hacks, had a thought about a modern DVI replacement. Maybe a wee box you connect to the system bus port that mimics a DVI. You could then plug-in a normal monitor into that box. If I understand the DVI correctly, it gave you an 80 column display but no graphics? Someone's made something kinda similar for the C64/C128 http://home.comcast.net/~kkrausnick/c128-vga/c128-vga.html Kinda limited uses maybe, but its kinda gets around the remaining "issue" with Tandy 100/102 - the 40 column LCD display. I can imagine a souped up ReMemed Tandy 102 that you can just plug into a modern monitor to get an 80 column display would be quite an interesting prospect. If you had a beige Linux box lying around, even plugging the Tandy 102 into that & using TELCOM for mutt/lynx etc in 80 cols.

bulk purchase of T102 for ReMem upgrades

Stephen Adolph — 2007-12-30T13:34:56

Folks, I'm considering getting a large quantity of T102, with the intention of upgrading them with ReMems. I would want to sell those to people on the list. Given my current price for ReMem is 65$ + 5$ shipping (in NA), would people be interested in buying a tested and working T102 with ReMem installed for 90$ + shipping? I can also tell you that I'm considering NOT selling ReMem further without installation by either myself or someone who is well practiced. I was planning to offer ReMems at a discounted price to help cover the extra shipping costs. So the model going forward will be 1) Get a ReMem installed in your favorite machine by me (likely) - shipping costs go up accordingly 2) buy an already ReMem equipped computer from me So, I'd like some feedback on that idea. thanks, Steve
