Econet Level 3 fileserver real time clock and more

Post by aferenbach »

Hi All

Just managed to lay hands on a BBC Econet LEvel 3 Realtime Clock module. As far as I know it has been well stored and cared for though I have no means of testing it.

I am open to reasonable offers.

Also pictured is a regular twin ROM cartridge compatible with Master and Electron cartridge sockets. Also well stored and possibly in need of a clean but as I don't have a working master I can't test it.

Similarly would love offers

I figured to offer here where the conniseurs are rather than throwing it open to eBay.

Thanks for Looking

Andrew

If it is dismantlable without damagin it, high-res photos of the top and bottom of the PCB would be nicely useful.

Alas, it did not disappear in my direction :(
It would be nice to see good quality, detailed high resolution pictures of it :D
Would whoever it went to like to try? :?:

I don't think the PCB can be got at - it's all sealed up in that resin type stuff.

(I didn't get this item by the way, but I do already have one.)

I've never fathomed yet what the RTC does, if anything, or how the time can be read or programmed. When I've tried it on a BBC B, it doesn't seem to respond to OSWORD &14/&15 which is the Master series set of calls - that's probably not surprising though, as I don't think there's the capacity for a device attached to the user port to service OSWORD calls.

The only way to read/write the RTC appears to be whilst the L3 server is running, but since you have to enter the time at start-up anyway I'm not convinced that the RTC is anything other than a security measure.

I'm the one that won the Level3 RTC, about the only thing I've won this past 2 weeks. :(

BeebEm has some code in the source to emulate the RTC, I'm going to see if I can use that and the real thing to figure out how it works. As for the epoxy, seems paint stripper will disolve that, but I'll see if I need to go that far.

Unsurprising as it's a piece of hardware, not software/firmware. I expect that the Level 3 file server specifically accessed the user port to talk to it. It would be possible to write an OSWORD 14/15 driver to access it once it's worked out how to talk to it, just like SoftRTC that comes with HADFS.
