Re: PAL, MCU, EPROM, Flash programmer recommendations please?

Thanks for the replies. I've found the TL866 with a set of adaptors available from the UK for only £2 more than the Chinese listing Gerald found. https://www.ebay.co.uk/itm/TL866II-Plus-USB-Universal-Programmer-EFPROM-FLASH-8051-AVR-MCU-GAL-PIC-Kit/362327119196?epid=8019725463&hash=item545c61155c:g...

Re: SCART image quality

Thanks everyone for the responses. In conclusion then it seems two of my screens are not well suited for BBC use. On the plus side I must have soldered my SCART lead correctly, and the picture on my big Samsung TV is great :D IMG_6201.JPG The 19 inch screen isn't totally unusable, so will make do fo...

I'm nor sure how technical an answer you are looking for here. Thanks Dave. Pixel clocks point is interesting - could explain the disappearing image on the LG TV. Could it also explain the colour bleed? Know my photos aren't that clear, but don't think they are scaling artefacts. To be honest I was...

SCART image quality

This weekend I soldered up an RGB SCART cable for my Master Compact using the wiring diagram shared in numerous threads (I think the Retroclinic design is similar). I've used 220ohm resistors, except for sync where I subsequently changed this to 270ohm (as per the diagram), which had no impact on im...

Re: Today I received.....

So if you have two 8K byte ROM images that you want to use, put them in a 32K byte EPROM as if they were 16K ROM images (that is pad the 8K byte ROM image upto 16384 bytes, then combine with the second padded image) :wink: Thanks Mark.

Cheap eBay EPROM programmer, a new 32k EPROM and some used 27C128 EPROMS.

Re: Missing old/new Electron Expansions

I’m a big fan of any mods that give an old machine access to modern storage formats (SD/USB) or data services. Beyond that, I think provided the machine can still run original software natively, then anything is fair game. There were lots of unofficial upgrades available back in the day and the rema...

No, used Commstar 1.4 for Telstar. Commstar II seems to have viewdata and terminal as separate apps. Might give Communitel a try.
