I just upgraded my coco1 to a composite video connection using the mod as detailed in http://www.cocopedia.com/wiki/index.php/CoCo_1_composite_video and it worked out well with one exception: the colors look incorrect! I expect that the background would be green when I turn it on, but it is more of a burnt orange. Has anyone else experienced this and found a solution?

Just bought a Sharp PC-1500 and plotter. It came with a UV EEPROM card that limited the operation. Once I took that out I got it working and reliving my early professional days after college. I have purchased a 16kB memory card.

I don’t have a the door memory slot. The UV card is a full module and there doesn’t use the door. Anywhere I can get one? Or does some have a 3D printer file for one?

I just got a model 4 taken apart and cleaned, and discovered a hole punched through the bottom of the keyboard PCB. Nothing on the keyboard functions other than the reset button.

I haven't taken it apart fully yet, but I assume the membrane and foil (ground) are also fried.

Does anyone have any ideas to repair this thing? I am willing to use modern parts, and would rather not buy another full computer to tear apart.

my brother and i are currently in the early stages of trying to clean up this trs-80 model ii found in our granddads basement. as you can see, it's a bit of a mess (seems like a mouse has been living in there for a while).

unfortunately we are missing the boot disk and from what i can tell on trs-80.com, the disks are only available for models 1 and 3. does anyone know where we might be able to source the disk for the model 2?

thanks!

i bought this from my physics teacher for 20000 huf (50 dollars) , the tape saving and the printer doesnt work, but its there +i got a random program on paper that doesnt work +its a rare hungarian rebrand Was it worth it?

Super quiet fan

64K more RAM

Gotek disk drive emulator

3 1/2” to 5 1/4” drive bay adapter that required mods with my drill press 😂

Cool period-looking TRS-80 Gotek badge

Cool period-looking 128K RAM badge

I also have plans for a hard disk emulator called a FreHD. Already have the “sled” for it.

Also considering the high-res card…

Shout out to Jay from NewSOFT for most of this stuff.

When i bought my tandy pocket computer 2, this program came with it, i know that this program is hungarian, and i dont have a working printer for it, so i replaced all lprints with just print commands, and after i input "kulonbseg" and "indulasi hossz" it just says its busy and hangs

This is a question that I encountered on scifi.stackexchange a few years ago.

I'm not the person who posted the question, but I do want to help the OP track this game down. I've re-posted the question on TOMT and tipofmyjoystick, without success.

Although the below text doesn't specify the platform, the question title explicitly mentioned the Tandy CoCo 2, and the OP believes the game was a BASIC type-in. Possibly from "The Rainbow" as his family had a subscription to it at the time. I've looked through several scanned issues of that magazine, though, and could not find anything similar.

I have, unfortunately, forgotten a lot of these details, but somewhere in the late 1980s to the early 1990s (we got the computer in mid elementary school, and I'm pretty sure this was before high school). The game involved some method of investing in shops. I think there was a standard set of names, and I remember some of them were puns that I didn't get at the time, like reference to "Knight wear" for an underwear store. I think one of the other stores was about either taxes or accounting (I know... weird thing to have stick in my head). There was a standard set of stores (maybe 50 of them), but more were available with an option (I think it displayed the standard list, then there was something else you typed in that let you scroll through a few hundred, or you could type in the corresponding number. I think the numbering was consistent between playthroughs). The other thing I remember was that it was possible to illicitly access the shops at night, where you'd often be confronted with a set of choices with different metal door knobs (in my memory, they were drawers, but doors make more sense) where I recall one of them invoked a spell to give you a nasty shock if you picked it. I'm 99% certain one of the knobs was described as being "silver".

This was implemented in BASIC. I remember that because I figured out how to halt the program, and move around the program's logic to cheat, although my understanding was pretty rudimentary, basically forcing a GOTO to a particular section. It might have been something my brother typed in from The Rainbow magazine.

Would anyone here be willing to make a copy of trsdos ver 3.2.1 so I can test my model 4 I recently purchased. No boot disk was included in the purchase and I'm pretty excited to give this a shot. I would obviously be willing to reimburse you for your time and materials.

I thought it would be as simple as just getting an external floppy drive for my modern computer and just using that to transfer the OS, but there's pretty much no 5.25 usb drives.

Been working with a non functioning model 4P for a while now, ive narrowed the problem down to the power supply, (its a tandy one)

Ive metered almost every componant i can reach and the only one i cant get an reading out of is the larger transformer, would i get a voltage reading out of it? I know for the fact the compaciters are charged, ive been getting correct voltages out of everything else

Does anybody have any advice, or a decent place to find a spare transformer?

does anyone know of any good in depth dives on the coding behind this game?

Computer functioned before the caps blew up, Replaced the caps with some standard X2 rated safety caps of the correct compacitance

and im still getting nothing out of the screen and the power supply is making a very slight clicking noise

Ive verified the caps were soldiered correctly And i cant find any shorts in the board

The clicking is coming from the relay side of the board

Tryin to upgrade from 4k to 16k. Just wondering where everyone sources their ram? Do they make new or is it all old stock. If you have a link to it that would be great.

Pic for attention lol

Sorta self explanitory

Cheaper machine and cheaper paper are ideal, but thats about it

When I turn on my model 3 this is what I get. Any ideas where I begin troubleshooting? I haven't used a TRS-80 since I was in grade school but am pretty adept with old computers. I presently have it partially disassembled and want to make sure I am not missing something obvious/easy/simple before I go any further.

Last year my wife's grandfather gave me his TRS-80 and over 100 floppies for it. They contain about 30 years of business records, as he used this computer to run his business from 1984 to 2013. I want to archive them, but I've tried to do it myself and it's just a mess.

I've tried all the advice I can find online for doing it myself, I've spent the better part of $500 building a computer that I thought would do the job, and it just won't read them.

Does anyone have the equipment, and the time, to archive these disks? I'm willing to pay for the service.

Is Ira Goldklang still around (the trs-80.com guy)? I sent him an email but I'm not optimistic that I'll get a response.

Edit: just want to put this where someone can see it. Ira's still around! I'm sending my disks to him.

I also had a war game that I ordered from a magazine. I think it may have been ww2 but I can't be sure. I know you could fire mortars and had troops. It may have been alphanumeric graphics. Good luck. I know it's not much to go on.
