Re: Strange Pegasus DFS fault

It's interesting, and possibly a clue, that these problems only started after I unplugged the board from the Plus 1 (and took out the DFS rom). Prior to that, it had been intact and in-situ for quite a while. This must have disturbed something I imagine. That's a similar problem to the one I've jus...

Re: Loss of output on Electron RGB Port

GREAT NEWS! I found a weird voltage drop in my C-sync signal coming out of chip 14 so I replaced that and now the old Elk works again! I think replacing IC 19 was also a necessary step as suggested above. So I just want to thank everyone here who read the thread and an extra special thanks to every...

Re: Strange Pegasus DFS fault

Just to throw a spanner in the works, at this point: I've been building the rest of the Pegasus PCB stock. Plus I have some later issue PCBs that look as if they were production or development repairs - the thing that stands out with both sets of PCBs, not counting the layout and shorts for the one ...

Re: Strange Pegasus DFS fault

If anyone needs a printed copy of the Slogger DFS User Guide for the Pegasus Interface (?) I now have them. Reformatted from the download that kicking around.

I also have the SEDFS ROM and can supply copies with a genuine Slogger label or just the lebel, if required.

What was the reason for switching from LS->HCT? I have a tube of LS245s as the Atom Colour needs them, so may tray them in the AP6, as I still have the top off the Plus 1.
Availability, at the right price . . . at the time I needed them.

There is no hardware fault, only firmware. If I *UNPLUG both roms, everything is OK. And... with 32k RAM in the AP6, may reported memory is c...

Re: AP6 SRAM oddness.

Phill . . . There was a problem, in 1V30. It was working until I had to start using 74HCT245's. It's supposed to be sorted in 1V31, however, I've not had chance to investigate. I'm building two AP6s tomorrow so I should be able to test then. The problem lies with the Data Bus on the AP6 - it's isola...

By default, both the BBC B and the Electron only output a monochrome (black and white) video signal on the composite video outputs.

That's even worse! I've found it interferes with a lot of programs and applications! If you don't actually need it then I'd remove it until you do - eliminates one more possibility!
