Re: Acorn Electron databus and ADFS behaviour

I've just found one of my Electrons that cause the Pegasus Interface to fail when used with ADFS. It was a batch of 4 Pegasus Interfaces and all were affected! Swapping to a different Electron and they all worked. I tried various 'fixes': replaced two HCT parts with LS (no change), different version...

Re: ABR (Advanced Battery-Backed RAM) Now available - Electron and Master - 19-07-21

I'd like a couple of these to replace the EPROM cartridges in my Master, please! Because it's for the Master, I don't need the Electron support ROMs nor two copies of the manual (maybe no copies, if it's the same as the ATI with ABR manual I got with that last year, for my Electron)? I'm not after ...

That's offered two post above yours :mrgreen:

Perhaps you can combine the shipment to the Netherlands, especially if there are other Dutch members interested. I'm not interested in this one because I already have a Tube and RAM expansion for my Electron.

You could also go SMD on the TTL chips and put them on the back of the PCB, that could bring the PCB size down to the width of the edge connector.

Re: Pegasus 400 - Electron Disc Interface - Now available - 19-07-21

Really nicely built Dave. If I didn't already own two Slogger 400's I'd take one immediately. If you want to get the price down further, integrate the two ROMs into a single EPROM and you can reduce the PCB size. Bryce. I was thinking more of loosing up to 6 of the 8 TTL ICs. But, Yes, I could inte...

I think the ADFS ROM tests for the presence of the 1770 disk controller. If this test fails, the ROM disables itself.

I would look for problems with the 1770.
