If you're doing a batch when you feel better, I'd quite like one for my Master, too?
I have a couple made up now if either of you are still interested.

Re: E-Bay Complaint

I've had the same issues when I've sold my VideoNuLA boards on eBay. I send out a printed cover note with my contact details and a link to the support pack. However, a small number of users have lost this in the time between receiving the board and getting around to fitting it. So, they naturally co...

Re: Master video display fault

I'd try reseating the 6845 a few times as this generates the sync signals. If that doesn't work, try switching it with one from another Beeb.

Also have a look at IC41 on the scope as this generates the CSYNC.

Re: Master Replay

I've dug out the Master Replay manual but, unfortunately, it doesn't contain any fitting instructions or technical details.

I'll have a look for the fitting instructions but it's possible that I fitted it by just working it out from the cable lengths etc.

That's all for the earlier BBC version, completely different implementation.
Even the "Vine Micros Master to BBC B Conversion Kit" and "Vine Micros Master OS Overlay Board"?

Re: VideoNuLA boards

Hi Graham,

Thanks for the interest. Unfortunately, I only have one here at the moment and that's reserved for someone who wants it fitting to a Master.

I'm a bit under the weather at the moment but I should be able to make one up on the weekend. I'll let you know as soon as I have one available.

Re: Sega Light Phaser on a BBC Micro

I have a light phaser wired up to my BBC B following tricky's pinout diagram. It'll work on a model B, B+ or Master 128. The Master Compact has a 9-pin connector so needs a different plug and wiring. The games should work on all Beebs but they were originally designed to be loaded from tape. So, it ...

Re: BBC b, reading the CRT vertical sync position.

Are you using BASIC or assembler? If you're using assembler, there's a useful discussion around sprite plotting (with code) here . It sets up a timer on each vsync interrupt that triggers as soon as the visible part of the screen has been rendered - this buys you back some time as vsync usually happ...

Re: MMC hard drive emulation?

There's an implementation of *SRLOAD from the ever reliable MDFS here . I'm guessing that you could load this into memory (using *LOAD) from the MMC DFS, switch to MMC ADFS and then *SAVE it to the hard drive image. Once on the hard drive image, you can use it to load the DOOMROM file into sideways ...

It does list the exact part number - might be worth checking a well known auction site from time to time.
