Re: California Devices Inc and the HCS10017

After a fair bit of searching, I've managed to find specific details about the seven devices that made up CDI's HCS Series, from two different sources: cdi_hcs_series.png That info is from a publication called IC Master 1984, Volume 2, and is from pages 4461 and 4463. There is copy on archive.org. A...

California Devices Inc and the HCS10017

I thought I would start a new topic to collect information on Calfornia Devices Inc, the company that manufactured the Oric ULA. I have spent the last few hours searching the Internet for information on this company and it appears that there is quite a lot of information out there about the company ...

Re: Reverse engineering the 6522 VIA chip?

Do we know, did the Pravetz 8D have the same supplier for the ULA as for the French & British built Oric machines? I assume CDI (whoever they were) created the chips for both the original Oric branded and licensed clone machines? Edit: I recall now already seeing what CDI stands for. It was Californ...

Re: Reverse engineering the 6522 VIA chip?

I quite agree, but unfortunately there isn't yet a die shot of the HCS10017 that I know of. Decaping and imaging isn't something I'm able to do myself. I would quite happily switch to the HCS10017 when a die shot does become available. On the topic of reversing the HCS10017 Oric ULA chip, if someon...

Re: JOric

I suspect it should run without issue on the Huawei P8 Lite, and probably also on the Nexus 5X, hopefully also on the 2013 Nexus 7. On my phone it is running full speed. The Oneplus One is about 4 years old now, and when released used slightly older tech for the time in order to fit into a more budg...

Re: JOric

A little bit off the topic we've been recently discussing, but still relevant to JOric, I was wondering how many of you use an Android phone, and what make, model and Android OS version it is. I personally use a Oneplus One, which is still on Android 6. So a bit behind the latest, but still going st...

Re: OType

I've only been in the Oric community for a couple of months now, but already I am completely in awe of Twilighte. That OType demo is amazing. Regarding unfinished games, I'm also very much in awe of the Wurlde demo, the one where it starts outside the castle and you can walk around between the vario...

Re: JOric

There appears to be a slightly different story in the article below with regards to the BASIC ROM: https://www.theregister.co.uk/2013/01/28/the_oric_1_is_30_years_old/?page=4 to quote that article: Paul Johnson reveals that Tangerine was not merely an early licensee of Microsoft Basic, but that it a...

Re: JOric

I cannot tell about the rights, but didn't the people in Tangerine blatantly ripped off a Microsoft Basic Interpreter without actual permission? :D That's interesting. I Googled that and found a few references years ago about this. So presumably if the ROMs were made without a proper license or per...

Re: JOric

I'm not sure how much interest there would be in an Oric emulator on the Google Play store. I'm the sort of person that would download it, if it wasn't me publishing it. Other than me, its probably just all the other members of the Oric forums. Would people be happy to install it on their phones if ...

Re: JOric

Out of interest, have you considered what your plans are for Google Play? Upload with system ROMs and whichever titles are available with suitable licences and just keep your head down over the former? If you're publishing to Google Play, I think yours will be the first emulator that has to go thro...

Re: Gamebase Oric V3.0

Hopefully people don't mind me resurrecting a topic after two years of inactivity, but I only just discovered the Gamebase. I'm not talking specifically about the Oric Gamebase, but about Gamebase in general. I'm not sure where I've been for the past 20 years. I thought I was a pretty big emulator f...

Re: JOric

That's why I care about using the actual colour ROM, because it's a knowable component, but haven't tried to deduce too much information about the internal counting structure. Although I have quite an interest in the CRT, blanking, sync, colour burst, and all that, I'm not intending to emulate thos...

Re: JOric

I've just been taking a look at my copy of The ZX Spectrum ULA book by Chris Smith and it appears the Spectrum starts its text window area when the vertical & horizontal counters are 0. So that's precedent. Maybe the VIC is unusual, and perhaps the Oric really does do it like the Spectrum.

Re: JOric

Thanks @ThomH. I actually managed to follow all of that. I must say I'm really impressed with the level of detail that you take your emulation to. I was impressed when I first read your posts many months ago back in the VIC 20 Denial forums, and have been impressed again seeing and reading what you'...
