  1. I foolishly bought a Zhongdi ZD-985 a couple years ago, and while it can do the job, it clogs super easy right by the vacuum chamber. My workflow currently is: Desolder a pin. Shove the cleaner (ram-rod) through the nozzle to ensure it hasn't clogged. Move onto the next pin and repeat. How is the FR-301 as far as clogging is concerned? The ZD-985 is an absolute pain to unclog when it clogs - since the clog happens beyond the heating element where the pipe is cooler. I've resorted to hand twisting a small drill bit into the pipe to unclog it.
  2. Here in North East Ohio we used to have Olson Electronics till the late 80s - I used to LOVE those stores! They used to sell random boxes of junk, er, parts, in various sizes. The one I used to frequent also sold PET Computers - that was the only time I ever saw one.
  3. The TRS-80 Model 1 was my first encounter with Microcomputer back in 1980. Our local library had one in their typing room - and you could sign up to use either devices (Model 1 or the Typewriter) for an hour at a time. A friend and I would sign up to use the Model 1 for two consecutive hours on Saturday afternoons, and usually no one else signed up after us, so we'd continue to use it for hours until the library closed. I was also friends with the manager of a local Radio Shack - he'd allow me to sit in front of the Model 3 display model and use it as long as I liked. He had a couple bootleg games which I copied right on the Model 3 - and I also would pop the cassette versions of the games on the rack into the Model 3 and copy them too when he was in the back room watching his soap operas. I really wanted to buy a Model 3 for myself, but couldn't afford it. In 1981, I was a junior and our high school got 3 Model 3s - one of them was connected to a printer. Students would do their programs on one of the two w/out the printer, and then CSAVE it to their cassette and carry it to the printer equipped machine for creating a hardcopy for turning in. About this time, I managed to find a used Model 1 4K Level 1 machine - and I had it upgraded at Radio Shack to 16K Level 2. I was then able to do my class assignments at home - and basically read programming books in class. I just had to reset the printer equipped Model 3 when it was my turn to print, since it was always defaulting to 1500 baud instead of my Model 1's 500. I was aware of the Atari 800 and I really wanted one, along with the Apple II - but they, along with the Model 3, were out of my reach budget wise. I continued to upgrade my Model 1 to a disk system - since I had already invested money into it already. In 1984, I retired the Model 1 and bought a CoCo II - since it could use my Model 1 floppy drive and cassette recorder - something the C64 couldn't - so even though they were similarly priced, I was already locked into the TRS architecture by my previous purchases. In 1987, I moved on and assembled a PC XT clone and thus my original TRS-80 Adventures came to an end... Until in 1993(earlier?) when I found a copy of Volcano Hunter running in a Model 3 emulator someone had created. It was an all in one package - just an EXE which contained the game and the emulator. That's when I discovered the joy of emulation and started corresponding with Jeff Vavasour - yep - I knew him before he made it big 🙂 I registered his Model 1 emulator, and send him ROM dumps from my CoCo 2 when he was working on creating that emulator. I also started corresponding with David Kiel about that time - and he was working on a CoCo emulator also - on par with his Model 1/3 emulators - in that they would use his disk format. I sent him my CoCo service manual to help him out - and when he was done, he sent it back. Finally in 1995, a co-worker brought a Model 3 to work - and asked if anyone wanted it - I jumped at the chance, and finally after about 15 years of wanting one, I had one! I made the foolish mistake of then deciding to get rid of my Model 1 and Coco 2 - and since I didn't know about eBay - into the bin they went. Yes, I tossed them in the garbage. A sin I shall carry to my grave. In 2000, I discovered the joy of eBay and bought a Model 4, and a Model 4P. The Model 3 was now being supplanted by the 4s - so I gave it away. Yes, honestly, I learned my lesson of binning working TRS-80s. In 2007, on a lark I bought an Atari 800XL and an Apple IIgs on eBay dirt cheap - and they sat in storage for 10 years until I dragged them out in 2017 and started experimenting with them. Those were the days before retrocomputing was the rage it is currently. I bought the Apple IIgs with 5.25" drive, 3.5" drive, monitor, keyboard, base unit, mouse all for the winning bid of: $36. It cost me $47 in shipping and I still have the email notification from ebay when I won 🙂 I have since started investing in Atari computers - since I had always wanted one as a teenager - and now I have multiple 800XLs, the 800 I always wanted, a 600XL, a 1200XL and just for fun, a 400 - with an upgraded keyboard. After reading about "The C64" - as soon as it was available on the US Amazon website for ordering earlier this year, I ordered it - instead of paying a scalper for an EU model. I received it a couple weeks ago - but haven't plugged it in yet - but I will.
  4. I am interested in one. Thanks. Jim
  5. When I first saw this issue last week and was bugging Thom about it (turns out I was running an older version of TNFS which wasn't compatible) I noticed that while the host entries disappeared - if I power cycled the Atari - the entries would come back. Jim
  6. OK - I recently needed to hook up the Fujinet flasher utility to resolve a TNFS server issue - and I figured since I had the notebook alongside my Atari, I may as well upgrade it to the latest version. Now - according to this page: https://fujinet.online/download/ This is the latest version: Latest Firmware Version Info: FujiNet Version: 0.5.32f7ef07 Build Time: Wed Oct 14 00:49:19 UTC 2020 So - I downloaded all of the components listed there from here: https://fujinet.online/firmware-dl/ in the event I'd need them to update my firmware piecemeal... Turns out - the firmware flasher said it was upgrading my FujiNet with the latest directly from the website - no need to download the individual files after all. Nice! Now - when it was all done updating - I assumed my FujiNet would be running the version listed above... However - the config screen suggests that I am running a build from August 25 And the FujiNet built in webserver suggests I am running a version from October 7th: This can be a mite confusing 🙂
  7. This is one of my all time favorite games of the 8 bit era, I've only ever played it on my TRS-80s and I was very happy when I heard there was an Atari version. Manual can be found here: https://archive.org/details/Commbat_1981_Adventure_International/mode/2up
  8. Who sells them in the USA and Mexico? I'm in the US and I'd be interested in one. Jim
  9. My first useful program was written for my TRS-80 Model 1 in BASIC back in 1981. I was 17 at the time. My friends and I were into wargaming at the time, and our "Goto Game" was "Star Fleet Battles". The game was fun - but a turn could take HOURS - since there was so much bookkeeping performed. The biggest time sink for our gaming group was damage allocation. If a ships shields were knocked down during an attack - you used two 6 sided dies to roll damage on a complex chart. If you rolled a 7 (for example) , you would find the row for 7 in the chart, and read the damage type from the first column for that row. If your ship no longer had any of those, then you'd move to the next column for 7 and take that kind of damage. It was very common to have have 50, 60 or more hits that needed resolved before game play could continue. One person would roll the dice, another would look it up on the damage allocation chart, and the person whose ship was being attacked would dutifully record it. For the rest of the group - watching and listening was about as much fun as watching paint dry, and it took almost as long. My program reduced the number of people involved to just 2, the person recording the damage on his ship - and the person hitting ENTER for the next damage roll. It made it quicker - but seeing that my model 1 wasn't very portable - it was impractical for every day use. Yes. I write programs in Python (mainly) to test new firmware builds for wireless networking products that the company I work for develops. Just like back in 1981, I'm still automating repetitive tasks using computers.
  10. FRE() is a reserved function name in Model 100 BASIC. Z = FRE(0) Returns the amount of memory available (free) for numeric memory in bytes Z = FRE(' ') Returns the amount of string space available (free) memory in bytes (From page 14 of this document: http://www.classiccmp.org/cini/pdf/Tandy/Model 100 Quick Reference.pdf ) As a rule with these old dialects of BASIC - you can't create a variable that includes a reserved word. You can use var names longer than 2 chars, but generally, only the first 2 chars were significant. Thus 10 ABCXYZ = 99 20 PRINT ABLLLL RUN 99
  11. I re-installed the Incognito in my 800 motherboard - and it WORKS! i think I might have had a bent pin on the small cable that fits in the socket where the 7442 is removed from. And yes - I had the orientation correct before - but I might have had one of those very delicate pins bent under - so it looked like it was in the socket, but it wasn't. I powered it up - and it dumped me into Sparta DOS - so it looks like it's alive! thanks for everyones suggestions and especially thanks to FJC for his above and beyond support via PMs Jim
  12. Looks like the same rev CPU card I have. Mine is wired identically.
  13. I assume you mean something is being shorted while the Incognito is plugged - since when I revert - it seems fine. Granted, I've only done limited testing with this 800 - but it seems to work fine with a BASIC cart and Star Raiders when I reverted it.
  14. With an incognito - do you normally get the memory test (?) sound effect on power up? I definitely don't hear anything. When I put the OS ROM back in and 48K of RAM - I definitely heard it on startup before either going into Memo Pad or BASIC or whatever else I tested it with. I will definitely try a cart when I have a chance - with the Incognito plugged in. I didn't have the keyboard plugged in - but I can try that also.
  15. I bought an Atari 800 a couple years ago - and found out about this great thing called the Incognito - which sadly wasn't being sold any more and was super expensive on ebay. So - during this past summer when I saw the post on FB that Lotharek was doing a new run - I fell over myself throwing money at him. I was cheap on the postage - no tracking - but it made its way to me eventually. In the meantime I watched FJC's installation videos - so I was all set when mine arrived. Last weekend, I finally cleared enough space on my bench to open up the 800 and started installing it. I got to the part in the video where he does the quick power up check. So - I hooked mine up - powered it up - and got this on my monitor I powered it off quick and double checked my connections. Everything seemed OK to me - so I took a bunch of pictures and showed them to FJC to see if a second pair of eyes would reveal my goof. He spotted I have swapped the connections from P5 Pins 3 & 4 - the ones to the resistors. So - when I got home that day - I wired them up correctly - and tried again. Same thing - blue screen with squiqqlies. It was at this point that I studied his example connections on the CPU card - and saw that it looked quite different than mine. I was confident that I followed the instructions though - and connected the wires to the right pins on the chip I identified as the Antic via a part number lookup on google. So - some more back and forth PMs and we realized I had a different rev CPU board than he did. Maybe mine is normal for NTSC machines? On both my CPU cards (I also have a parts 800 that arrived smashed from ebay) pin 1 of the large 40 pin chips is towards the card edge connector. My CPU cards are oriented in the same layout as in the 800 service manual I downloaded. I reverted my 800 temporarily back to an OS card and 48K - and it booted up fine into notepad. So I at least didn't kill the machine. I emailed Lotharek and he assured me that every Incognito is tested prior to being shipped. So - I've pestered Jonathan enough these past three days - and I thought I might see if anyone else has any ideas what might be wrong. Hopefully I didn't kill the Incognito with my wire swap accident. Mine did come with a populated JTAG header - so if there is something I can do via that - it's an option. I did originally plug the CPU and Incognito cards in the motherboard correctly - I double checked the video to see what the orientation was prior to applying power. I also had the P4 cable connected properly - the 74LS42 replacement. I have both jumper wires on the motherboard correct - I double checked against the video. (Ref from the memory card slot to the personality module slot & RNMI to Reset) Any ideas? Does anyone else have it working with this style of CPU card? I also have a TL866 if I needed to reprogram something. Help? Jim
