    Apologies for a mistake at 2:55! I mis-read my script and said 1992 instead of 1982, so totally my fault. Worse, I can't edit the video and re-upload without losing all the views and comments, sorry!

    Omg this was my first computer, my aunt bought it on my behalf from WH Smiths. What I really wanted at the time was an Acorn Electron, but it was out of my price range back then. They accidentally gave her a 48k spectrum. When she realised the mistake, she returned it to the store and they swapped it for the Oric 1. I wrote my first Sprite routine on it, held in a DATA statement(hand assembled using gridded paper) and then called by locating the DATA in memory and POKING coordinates, but due to some bugs in the ROM, the moment I added any other BASIC code past about 10 lines, the assembly code would become corrupted. Needless to say, I rapidly got fed up with it's antics and misbehaving and got rid of it. The one impressive thing about it for the time was the AY sound chip, but I kind of wished my Aunt hadn't returned the spectrum.

    • @RetroKrazy
      @RetroKrazy  10 หลายเดือนก่อน

      Thanks for the laugh about the Spectrum! However without ever having got the Oric, that story would never have existed and it's a memory that's stuck with you :)
      I love the design and the keyboard is nice to use (short term...), but I've yet to stretch it's legs and hear what that AY chip can do yet!

    Really enjoyed this video chap , wondered why they use a 7905 as that's negative 5v, found myself shouting at the TV "zero page is falling over" lol , remember as a kid seeing an original in a shop in my town running manic miner I think and remember thinking , that looks like a speccy with a better keyboard lol 😆

      Hey Lee, I vaguely remember reading about the 7905 but not why it was chosen unfortunately. Sure someone reading these comments could assist!
      I never really saw them about round here, and while the keyboard does indeed feel better, the thin keys I recon will start to hurt the fingers after a while :(

    Hi, great video. The power supply is a linear power supply, they give more voltage than rated if there is no current flowing (like in your case when measuring with a high impedance meter). The voltage will come down when sipping milli amps from it, coming down to the rated voltage at the rated current printed on it.

    • @RetroKrazy
      @RetroKrazy  10 หลายเดือนก่อน +1

      Thanks for the feedback! Yeah, many systems don't show their 'true' voltage until under load, with the ZX Spectrum being one of the worst offenders generically. I've seen them up ove 14v!

    I had an Oric Atmos after my ZX81 and I loved it! I learnt so much about BASIC, Forth and assembly language. As far as I could tell, there wasn’t many differences between the Oric 1 and the Atmos other than the keyboard of the Atmos being far better.

    • @RetroKrazy
      @RetroKrazy  10 หลายเดือนก่อน

      I was ZX81 to Spectrum and it's "dead-flesh" keys. Was still and awesome machine though :)
      From what I can tell, the keyboard changed as did the ROM to v1.1. There was a kit available back then too should you wish to add the updated ROM to an Oric-1, with a switch to flick between the two for certain games compatibility. However, the red and black look I think made the machine as it was just so different to most other machines!

      Most of the retro TH-camrs I speak to, we all use the video leads made by Ian Priddey: www.retrocomputershack.com/ While not the cheapest, they are excellent quality, give a great picture and work via SCART cables direct to your TV.
      As for software, eBay is the usual go-to for genuine tapes, though prices have become expensive these days. An alternative is either something like the SVI-CAS I reviewed, however for use on the Oric only, try the Erebus: www.ebay.co.uk/itm/174120579582

    Lovely video. I remember the Oric 1 and Atmos but had a Speccy so didn't pursue it. I did like the inclusion of an AY chip which put it ahead of the Spectrum in the sound department. That chiclet keyboard really hurts the fingers after a while! *Neckbeard Alert* @2:55 released in 1982, rather than 1992!

    • @RetroKrazy
      @RetroKrazy  10 หลายเดือนก่อน

      I had a suspicion the keyboard would hurt after a while. The danger of the small form factor forcing the use of narrow keys! As a Speccy owner too, I was never swayed to anything else as most of my friends had them too.
      And lol! The number of times I've listened to this while editing and completely missed the fact I said 1992 instead of 1982! Well spotted!!! Just a shame that unless I was a massive channel, I can't replace the video without losing everything - all commets, views etc :(

    Mixed memories of the Oric-1. Nice enough looking system but a nightmare to program - a very weird graphics chip using serial attributes rather than the memory mapping of e.g. Spectrum / C64. Shame because Tangerine did some good stuff... the Microtan 65 was a geek's dream to play with.

    • @RetroKrazy

      It's not a difficult job to replace that capacitor and get it fully functional again! Though having a volume switch on the internal speaker would be nice as it can be quite loud in a quiet room :)
      Going to guess you have the Erebus as that seems to be the most common one! I went for the SVI-CAS as it works with so many more systems and allows full testing of the tape loading circuitry, though the direct SD Card reading systems and great for speed and convenience.

    I had one given to me by my uncle who lived in the UK. I had an Atari 800XL, so I thought it was nice of him. It was busted from day one. The keys would stop working randomly after a little while. I had my dad look at it, being an Elec. Engineer, but he he no clue... Sad, but other than the bad keyboard, I liked it over all. I had no games or anything for the Oric. I had a game with like 100 BASIC games or something like that. Could never type them in, as the keyboard would slowly stop working. Any rough ideas what it could've been? I no longer have it, but would love to own one again for pure nostalgia!

      I never owned 9ne until recently so it's still all new to me as well. I'm currently,on holiday and dont have access to the schematics, however if it slowly stopped working, there is possibly an IC that was failing. If left off for a bit and it started working again before slowly failing once more, that'd confirm it.
