Re: Today I received.....

My first ever Atari (excluding an old Woody console) - a 520STE, upgraded to 1 Meg. Even came with a free Gotek.

Now I have yet another system to know ****-all about! :lol:

Re: Today I received.....

Well, almost three years later, I've finally obtained a case, keyboard and PSU for the motherboard -- just need to find out how much damage the battery did (I neutralised it three years ago, but a couple of the inductors for the mouse port have snapped off) and put it all back together. I also need...

Re: Acorn System/Atom Econet

Many decades ago, I discovered several System 3s. These had been used for lab purposes, and to run an Econet of Atoms.
Amongst them was a disc labelled as being System 3 Fileserver, an image of which is posted here.

Re: BBC B+ vs ABC

I've just double-checked on a couple of ACWs, and the model code for the motherboard is the same as for the B+ (0233,000). There are, however, some important differences in how the motherboards are assembled - the ACW has vertically-mounted connectors for the 1MHz bus, user port, etc etc. It also ha...

Re: BBC B+ vs ABC

The ABC/ACW definitely came first, by quite a considerable margin. I’m not aware of any significant differences between the ABC and B+ boards. IIRC the ACW board looks pretty much like a B+ board cobbled into an all-in-one case, just with slightly different writing on it. Functionally, it’s hard to ...

Re: Today I received.....

Can’t really comment yet, since I’m a newcomer to Commodore stuff in general. I’ve just acquired the SD2IEC for my real 64 as well, but don’t yet have any games/disc images to try on either machine.
Probably need to get a Pi1541 at some point too.

That would be S2. Also make sure S9 is made, otherwise it’ll still be looking for a disc interface that may or may not be there (but may have been in the past).

Re: Another dead A4

Okay, so all caps removed. A few were a bit ropey and had leaked.
Five pads came off - C19 west, C89 south, C134 both, C65 east. Everything else seems relatively unscathed.

What’s the best way to repair these?

Another dead A4 (resurrected)

I think I know what the answer's going to be, but I'm going to ask anyway, just in case before I start... A couple of years ago, my A4 was working. I removed the battery before it could leak and soldered a couple of flying leads in its place. When I reassembled it, it no longer worked. So I boxed it...

Re: YARRB [SOLD OUT]

Is that an otherwise expansion-free Atom? In my case, it appears to work fine (so far as I can tell) with no other expansions fitted - keyboard works etc, and only hangs if AtoMMC is fitted *and* the machine knows about it and tries to use it. Could it be that the W65C02 is more fussy about timings/...

Re: YARRB [SOLD OUT]

Thanks Dave.
The link options are as I thought. I've tried with both R1 and R2 fitted, and just R1. The result is the same - AtoMMC and the W65C02 just won't play nice together.
I suspect the effort required to get them to do so probably won't be justified by the benefits of succeeding.

Re: RiscPC palette weirdness

It's now not recognising the keyboard that it was quite happy with yesterday. The list of issues is growing, and I suspect it's time to take it down to the bottom of the garden and shoot it. :( I'd still dearly love to know why there's a difference between RO3.5 and later variants in terms of colours.
