Re: Oriclopedia: A series of videos on all things Oric
Wow, I'm totally speechless! :shock: Congrats for Oric Nova64's - they look in very good shape and making them work should be easy. IMO, you may definitely do something with the power boxes - it's pity to have such big case only for power supply. If you already have a Gotek can you check how it fits...

Re: ROM 1.22?
I am curious, however, about why you want to put a new ROM in an Oric. For those particular ROMs 1.2x I'm really nice surprised by the way they are made - all changes are on carefully selected places, without affecting the well known and commonly used BASIC entry points, so no big concerns about th...

Re: Jasmin time
No, I've tested every page as read buffer and it works i.e. no problems at 0x0200-0x02FF, 0x0400...0x8FFF and even 0xC000...0xFFFF with RAM overlay enabled.

Re: ROM 1.22?
Just remember that the Oric with the EPROM won't work with a disk interface (I think also won't with Erebus) out of the box. It needs some hardware patching. +1 Good advice! And the common sense is to follow it ... but don't forget this is Oric ! Here is at-least one proof that there are exceptions...

Re: Atmos ROM
Bit delayed but as promised here are the results from the test : https://youtu.be/9QGZiYRlDH4 I used Jasmin instead of Microdisc (because it's on my small working table already) but there should be no differences related to /ROMDIS signal. I'll repeat the test with Microdisc asap just to be 120% su...

Re: ROM 1.22?
What you mean with "changes"? You need to burn the ROM-file to а suitable EPROM (for instance 27128) with an programmer and use it.DigitalDunc wrote: ↑Fri Jan 10, 2020 8:08 amWould there be many changes required to run these new ROM images on a real Oric? I’m aware the keyboard could be an issue.

Re: Jasmin time
Maybe I need to read your messages more carefully... @Chema ; Please, do it, your opinion is important for me, honestly :!: Above problem is not related to any alignment. My (thanks to jorodr's ) Jasmin controller is most probably faulty. Something happens with the data bus and WD1770 starts to beh...

Re: Jasmin time
After almost one month of 24/7 hard fight with Jasmin I can say that I'm really(!) close to finish this project ... surprisingly with success! :) Here is a story about the last issue I hit (sorry for the number of videos): From the very beginning of my work I prepared some demos with series of sampl...

Re: Jasmin time
... Jasmin's independent clock should cause a race condition on the data request bit ... Yes, there is such race condition and even more - what you read from status/data registers depends on alignment of some addresses :shock: . I'm preparing to publish lot of info which I've collected recently... ...

Re: ROM 1.22?
@HigashiJun : if you download the ZIP files and decompress them then you'll find documents for each version which describe very detailed all changes. What I can make as conclusion is that all "localized" versions (i.e. uk,fr,de,se,es) are made to be used only with emulators, so your "...

Re: Clock Signal — an Oric emulator for macOS and Linux
Thanks, @ThomH ! Perfectly timed release - just what I need at the moment :). About the Jasmin button: actually there are 2 buttons on Jasmin ver.2 ;) - the left button acts as simple reset with paged BASIC ROM, the right button activates Jasmin ROM tries to boot and if there is no disk then falls b...

Re: ROM 1.22?
Every zip file contains a nice document with all changes explained - very good! With quick compare I counted dozens of JSR/RTS -> JMP - this will give some speed up. Else what bothers me is the software compatibility but I think the changes are made very clever and the chance that something fails is...

Re: Oriclopedia: A series of videos on all things Oric
Thanks, Dbug, very cool video! I have some comments: - I know everyone is aware of this simple rule, so just a remainder: Safety first! Avoid to plug/unplug cables when devices are powered-on! ;) - Your Oric got frozen twice in very specific condition - whole (video) memory filled with 0x55 except t...
