Re: BeebSCSI mini

I'd be interested in another board when a new batch is produced.
Should have ordered two when I had the chance first time around.

Re: BeebSCSI mini

Mine also arrived today. Big thanks to Simon and Jason.
I won't be able to play with it until Christmas as I'm away for work from today.
The combo of Matchbox CoPro and BeebSCSI should make for a very nice Model B. :)

Re: Weirdness with BEEB.MMB and games menu

Hi Dave, You're absolutely right. I do have ADT installed. What's weird is that it's been installed all the time, and I've never seen this behaviour before. I really can't explain it, as you'd think that the *MENU would always have been handled by ADT. Oh well. Problem explained and solved. :D Thank...

Weirdness with BEEB.MMB and games menu

Hi All, Having a very frustrating day. I've got a home built MMC interface and also one of sirmorris's interfaces. They both work fine in my Master using the BEEB.MMB games menu system. I'm running them with MMFS 1.27 currently (as that's what I had lying around in EPROM). In the past, I've used thi...

Microvitec Cub with collapsed vertical display

Hi All, I've just dug my Cub out of hibernation, and it has a bit of a problem. The display has collapsed into a single horizontal line across the middle of the screen. Looks like vertical scan has gone AWOL. It's a model 1441 MS4 according to the sticker on the back. Was just wondering if anyone ha...

Re: Unusual mask ROM in Master 128

But... by my understanding ~CS is tied permanently low on the MOS ROM in the BBC Master, i.e. it's always enabled. If early chips got that wrong, why the need for the logic chip? Would it not have sufficed for the carrier to tie CS to +5V? Hmmm, you're right. Any chance Andy could trace the connect...

Unusual mask ROM in Master 128

Hi All, Just wondering if anyone has seen one of these mask ROMs before? It's marked as 547MV V9482 231024-1028 0201,843-0 (c) ACORN It's on a small daughterboard and has a 74LS04 on the underside. I've only found one reference in my Googling, which is here: http://mdfs.net/Docs/Comp/BBC/Resources/M...

Wanted: BeebSID PCB/kit

Hi All.

Sadly, I missed a PM from Phill offering me a BeebSID PCB earlier in the year, so am on the lookout for a PCB or kit.
I've got the SID chip, so that part isn't a problem.

Please drop me a PM if you can help.

Thanks,

Andy.

Re: A new version of Phoenix for the BBC

Thanks for your continued work on this. You seem to be picking on some of my favourite 80's arcade games. First Astro Blaster and now Phoenix. How about doing Pleiades next? That'll cover my top 3 raster based games from the early 80's. :D :D

Re: A demo of what is looking like a new Frogger for the beeb

I'm afraid that there is no simple tweak, Frogger has 32 "screens" per "frame" and relies on some very tight timing. I'll have a play and see if I can make it work, the quick fix wasn't! Is there a useable mode on the TV for now? Thanks for getting back to me, Tricky. I suspecte...

Re: A demo of what is looking like a new Frogger for the beeb

Just moved my Beeb onto a flat screen TV in my study, and the vertical position is slightly different from my CRT screen. Sadly, the flat screen won't let me adjust the display downwards, so the top line or so of the screen is off the top. I can usually deal with this using *TV255, which is what the...

Fantastic work, Tricky!
Frogger was one of my all time favourites in the arcade back in the 80's.
