Re: Beeb FPGA port to Spectrum Next

The Wiki page is really good but there is no mention of the Spectrum Next version needed? The only hard requirement should be v1.27 or above of TBBLUE.FW (“the firmware”), which you can get from here: https://gitlab.com/thesmog358/tbblue/-/blob/master/TBBLUE.FW The rest of the Next system files sho...

Re: Beeb FPGA port to Spectrum Next

Garry had a look at launch.bas, but it's currently using banks beyond those the firmware loader is able to address. So your master core will need to be tweaked to use banks in the lowest 512K (first IC only) before it can use core.cfg to load the external ROMs.

Re: Beeb FPGA port to Spectrum Next

There is currently no standard way (that I'm aware of) for additional cores to access config files on the SD card. It's down to each core I think to develop it's own implementation. None of the Spec Next implementation is leveragable, because it's C code compiled down to Z80, running on the Spec Ne...

Re: Beeb FPGA port to Spectrum Next

Now might be a good time to mention how the Next core uses the ps/2 socket. The assumptions are that: the majority of cased Next users will plug a mouse directly into the board ps/2 socket, and not use a ps/2 keyboard at all. the majority of board-only Next users will plug a keyboard directly into t...

Re: Teletext to Viewdata server

Ah, I see. That is unfortunate. I wonder if we can invent something where pages are limited to 920 chars by default, but modern clients could opt into not having their pages not being truncated. Similar to the IAC DO SUPPRESS-TYPEAHEAD codes (or whatever they actually are, I typed that from memory)....

Re: Teletext to Viewdata server

In NXtel I escape the control codes on the fly for transmission, and I unescape them on the fly for receipt. I also have a fixed 960 byte buffer at both the server and client end, but it can hold a complete page of 8-bit characters. My understanding is that 7-bit escaping is part of the transmission...

Re: BBC BASIC for SDL 2.0 version 1.04a released

False positives like this aren’t that uncommon, especially for some AV software that uses aggressive heuristics, or when software packages regularly release updated versions. It often happens with software I release. Even for data files that contain no executable code! In my opinion you should persi...

That’s a shame. It seemed ok on latest Safari/Chrome Edge on Windows, but IE11 is broken in the same way. Bunch of javascript errors and possibly unsupported APIs.

Are you trying to send Telnet negotiations at it? Those aren't supported... Not as such, but I always initially send IAC DO SUPPRESS-GO-AHEAD (FF FD 03), might that upset it? None of the other services seem to mind. Late to the party, but the TELSTAR server normally throttles outgoing page traffic ...

I actually managed to solder one of these the other day, using a fine pointy tip. It actually worked, as well. At least after I spent ages prodding at it with multimeter probes to find out why it didn't work, which must have brushed a whisker away. LOL. Anyway, quite chuffed. https://dl.dropbox.com/...

Can you send the data in blocks and do the CRC checks at the end of each block received, rather than as you go?

Re: Printing a capacitor

Sugru is great. It doesn't last very long though. I don't know what the shelf-life is these days, but I used some that had expired, and it had denatured and lost its strength after setting. My biggest problem is that I don't use enough of it to be able to keep some handy for off-the-cuff repairs.
