I am glad that the Centurion restore project has got others to dig into other old systems. My first machine was a home built 8008 with 1KB from static RAM , next was a TRS-80 Level-1 which I upgraded to 16KB of DRAM. Even working at Warrex - Centurion I could not afford a Centurion CPU4 back in the mid 1970's. Regards, Ken R
Hi Ken! My first computer was a Model I Level I with 4KB RAM (purchased waaaay back in 1981), didn't take long to run out of memory :) The BASIC was...well...pretty basic but still a good intro into computing at the time. Would have loved to get my hands on a Centurion or any of the mini-computers of the day, so must live vicariously through watching those amazing restoration project videos.
It tickles me that a typo has become such an iconic program for vintage computing g. Watching channels like yours has given me the bug to pull my 286 out that I used to run my BBS on and see if I can get it working. Maybe I'll have to record a "HELLORLD" program of my own.
I miss those days when computers like 286's and up came with a "TURBO" button on the front 😂If you have BBS stuff you should post that as well, would be great to see that stuff running again.
Oh what fun! I learned my first programming on a TRS Model 1... It was in 1978 and I saw a flow chart on the back of the Radio and Electronics Magazine and I stared at it for like 5 minutes and then realized I understood how to program... I got on my bike and drove over to Radio Shack where the computer was set up and I asked if I could try it out, the store manager was very nice... I put in the instruction and it would execute... I asked the question why did it do that immediately, he asked me did you put in a line number? I asked back, what's a line number?? And from there I began to self-learn basic... Later I got into Commodore and learned 6502 assembly, and in college got into the CP/M OS and a ton of other things... but this brings me back to my roots.... Thank you for a fun dive into this computer and memory lane.
It's interesting how much Radio Shack was an influence in so many lives. I used to literally live at Radio Shack, went right after school everyday playing with the TRS-80s and their "Science Lab" kits. Only place where you could find 70s red carpet, a battery of the month club, and CB radios right next to the latest technology. I finally convinced my dad to get a Model I level I 4K machine. (No "Syntax Error" --- just a "What?" or a "How?" error message 😀) Soon I had memorized the entire "26-" series and ended-up working in a Radio Shack for a couple of years. Best times!
@@dipdoting Good Times those were, Yes Battery of the Month Card... I remember those. We couldn't afford a Model 1 4K, but I really liked them, I got a Commodore VIC-20 and wrote games that were sold commercially through a company here in the SF Bay Area called "Wizard's Magic Toy Box" sold on Cassette tapes.1982. Titles were "Muncher" and "Search and Destroy" although Muncher was a title that others used for a Pac-Mac knock off, my game was closer to a couple of other games like centipede and Blue Meanies, but had its own unique story and goals.
This is quite a dream machine... I love a nice TRS-80, love CP/M, and love 8" floppies... so it doesn't get much better than a Model II. "Hellorld" on this is "too easy" though... I'm looking forward to seeing it run on relays! ;) :) ED was a hideous editor, even back in the 1980s. At college, we always used WordStar in "Non Document" mode for editing source code. Woah! Even though I haven't programmed CP/M since 1984, I can still remember that BDOS strings are terminated with a "$" and how, back then, before any of us had ever seen a C compiler, we wished it was a null byte. Must have been such a pain when writing financial software.
I did a crash-course on BDOS once I realized I didn't have any high-level languages. I'm thankful there's so many great folks who've taken the time to post the documentation on-line. As for the $ termination, I thought the same thing, how they ever reflected the cost of something on the screen 🤣
Remember doing this in TRS-DOS , but earlier in Basic. Knew I had seen a Model-II or 12 running CPM+. Remember the Pickles And Trout name because it sounded so weird.
This was my first time hearing about Pickles and Trout - strange indeed considering most software companies in the 70s / 80 were trying so hard to sound futuristic!
Trash Eighty, eh? Nice to see it going. David's challenge is indeed fun, maybe I'll do it on a C64 after I get it going. I like your thorough explanation, and really good video production. Using OBS and a multi-cam setup, I presume?
Hey there, for the multi-cam I just used the Final Cut Pro multicam - it auto-synchs between two or more clips with the audio track and makes it easy to switch views during editing. That said, I'll definitely be using OBS for future videos, saves a lot of clip management 😁
Very interesting that it signs on as CP/M 2.1 -- I've been asking around online if that version even existed. Do you happen to have a disc image of that boot floppy?

One that wrote parts ordering software was Galactic Software.@@dipdoting

Been trying to program asm on my coco3 very cool , wish I could revive my eagle 2 and do some real coding
Those Eagle IIs look amazing - like a hybrid of a Model III & Apple II! Hope you get it up and running, would be great to see!
@@dipdoting hard to find information on them that’s my main issue special little computers lol

I'm just in the process of picking up a FREHD and once configured I'll make an image for you!
