Re: Announcing... the AtmoStrat !

The PSU connector is the same as in the original Oric. There is a lot of 5V PSU-s on the market with this usual connector. I'm using quality 5V 4A PSU form TDC similar to this: http://www.ebay.com/sch/i.html?_odkw=5V+3A&_osacat=0&_from=R40&_trksid=p2045573.m570.l1313.TR0.TRC0.H0.XTDC+5V.TRS0&_nkw=TD...

Re: Announcing... the AtmoStrat !

Fabrice is completely right about the computer detecting. For now the only way is by using keyboard subroutines detecting.The problem is that AtmoStrat is not "standardized" yet. I think it's good to have a discussion what must have in the final variant. I prefer to replace TeleAss with TeleForth.

Re: Announcing... the AtmoStrat !

If there is interests I could order boards to the PCB factory. The problem is that the case must have some little corrections because the height of the board (all chips are on sockets) and to cut a bit for a mode changer. So I think maybe it's better to make full upgrade service. What do you think?

Re: Announcing... the AtmoStrat !

Thanks iss. Actually I have no any doubts about video ram (bank 0 and bank 3) refreshing. I have doubts about the other two banks - 1 and 2. the idea of the ram refreshing is simple and no way to not work, just need reading of datasheets and some testing. And don't forget that the whole think is mir...

Re: Oric SD Drive in production

I'm interested of Cumulus just to integrate it to AtmoStrat project, nothing more. If HyperBasic could use my SD Drive I will prefer, but...
About Cumulus - iss is more interested and knows more about it's issues.

Ok, my mistake :) I'm not interested in Cumulus, so I haven't used a bit of it's code.

Re: Oric SD Drive in production

The way the cumulus generate the /MAP signal is just crap :/ I'm sorry for retromaster, but this is clearly not the best part of the cumulus I mean - I use the same oscillator, but not the same code. My controller was made a lot before Cumulus: http://forum.defence-force.org/viewtopic.php?f=23&t=839

Re: Oric SD Drive in production

Halmar The SD Drive don't need to use via amplibus - there is internal. So if you use some kind of amplibus it may cause problems.

Re: Oric SD Drive in production

When using real floppies, compared to Microdisc it's the same, but not so reliable. Just to mention. Dos 8D is absolutely best reliable as OS. Some of Dos 8D compatible floppy drives are not so reliable, because of temperature dependencies of resistors and capacitors forming Q3 and MAP signals. My ...

Re: Oric SD Drive in production

The speeds are equal or maybe Dos 8D is a bit faster. The disc access is very fast.

Re: Oric SD Drive in production

There is most complicated controller schematics I have attached. It rules Overlay RAM. The addresses to switch ROM/RAM are just writing to #380 / #381.
