Have you tried Mark Haysman (Retroclinic)? He might well have a drawer full of serial ULAs rescued from dead boards.

Mark was selling Compact serial upgrade kits on eBay so might well have some.

Glad you've been able to make progress. Is there a way I can convince it to use the files from c drive instead? It might be worth trying CD A:=C:\directory replacing C:\directory with the actual path to the files. This is the DOS Plus equivalent of the MS-DOS SUBST command. However, I can't remember...

Thanks so much for the image Rob, initially when I used the image and did *dosboot my beeb went a little crazy beeping at me and displaying jiberish I think I usually boot into DOS by doing CTRL-A-Break (with the 80286 co-pro enabled). It then auto-boots. Do you know if there's a way to inject the ...

The only CoPros that start up are the four 6502 ones. Will there be somebody at Cambridge who can reprogram it? Might be worth checking the soldering on the RAM chip on the back. When I reprogrammed trixster's, I couldn't get all the co-pros to boot up and then I noticed that some of the pins on th...

I found this on eBay (link)

I've bought these in the past and they seem reasonable value.

I have an original Oak SCSI card that's hooked up to a more modern Seagate drive (2GB I think). I found that some Seagate drives can be persuaded to switch to 256-byte sectors - I did this by issuing the relevant SWIs on my RiscPC. There are some threads on here about it somewhere. I also have an Ak...

I think this would be awesome if it could be done. There's always a thrill when a game uses the speech upgrade and to use it in such an authentic way would be brilliant.

As a kid in primary school when computers first appeared, getting to use the school's Beeb for a day was a big thing. However, computers were new and exciting at the time and few of us had computers at home - I had a ZX81 so getting to use the Beeb was still very exciting. I think it's inevitable th...

I think I have seen on the 8 bit guy he used something to do with car brakes for some or other but if it gets on the main case you end up with a pile of goo.

This stuff was definitely sold as contact cleaner and I didn't have any problem with it melting plastic!

I can point you at a CF card image that has a known good installation of DOS and GEM if that would help. It's the one I use with my DC and Pi co-pro...

PM me if you want the link.

Best wishes,

Which one, at one stage Maplin had about six or seven different brands/types of 'contact cleaner'.

Think there was only one type in our local store. Had a green lid.

I thought maybe halford in car section.

Halfords sell contact cleaner. I've found it to be better than the stuff Maplin used to sell.

A real 'B' give the correct image as do the two Masters that I have tried using MMC, but the two Masters that I have tried with data centres give the image on the left, but I'm not sure how far off the timing is. Hi Tricky, I've just briefly tried this on my Master 128 with DC and it looked fine. I...

my burner accept only .jed files for GAL programming, and i didn't find an easy tool to compile source if3.PLD posted by IanS: anyone can attach the jed files please?

Try the attached file - I've just created it with WinCupl so haven't been able to test it etc.

uIDE looks great Jon.

Do you know if it's possible to use the same PCB in an Amstrad CPC6128, Einstein and Enterprise? Ideally, I'd like to upgrade all three machines with hard drives...

Thanks,

Rob

Thanks for all the links. It seems that the SD Apadpter Premium is only available to pre-order but it might still be my best bet. The 1MB memory expansion is available and looks very interesting. I've been playing with the EP128EMU emulator and the Enterprise got far more games than I'd realised. Th...

Interesting coprocessor! https://m.ebay.co.uk/itm/RARE-VINTAGE-ACORN-BBC-MODEL-B-MICRO-COMPUTER-w-Opus-Disk-Drive/263797161782?_trkparms=aid%3D111001%26algo%3DREC.SEED%26ao%3D1%26asc%3D52962%26meid%3D770ae942d99e4d67868670c19a7228a2%26pid%3D100675%26rk%3D1%26rkt%3D15%26sd%3D263797161782%26itm%3D263...

I picked up an Enterprise earlier this week and have been having a little play with it. I've been quite impressed with it and would like to turn it into a more useful machine. My first project is to make up an RGB cable an then I'd like a convenient way of getting software onto the machine. Does any...

Are the BBC's ADSR registers in hardware too?

ADSR

He means envelopes. And I believe the answer is no - it's done in software. Still, the Beeb has to do something with all that extra processing power

VGM export for an emulator is jolly good, but it doesn't really help me get things from a 2DD floppy disc where I havew saved my work from my BBC Master. Do you have a PC with a floppy drive? Omnidisk or Omniflop will produce a disk image that you can then use in an emulator. Alternatively, if you ...

I also think the XZ81 served a very useful purpose. It was my first computer and was cheap enough that my parents were prepared to risk buying one when it was not certain that I'd take to it Completely agree. My first computer was also a ZX81 - my uncle had built one from a kit and I was amazed the...

Thanks for pointing this out Steve - I don't remember seeing this BITD and it's really interesting. If so, it's probably nothing more than a variant of the usual palette extenders but using the 1MHz bus (since the user port was used for the mouse/trackball)… You may well be right but I'm not entirel...

Had a look through my A5000 8MB expansions. Two are by Simtec and the other is by Atomwide but not the one shown in this thread.

However, it does have two GALs fitted - it's possible that they are similar to those intended for this card.

What are the cards in the box? https://www.ebay.co.uk/itm/BBC-MICRO-JOB-LOT-LARGE-QUANTITY-OF-STUFF/253714530155?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2060353.m1438.l2649 One says "Acorn 80x25vdu" on the silkscreen.

Thanks. ZIDEFS may do the trick though have a vague thought it was for the Ian Copestake interface - but too long since I've looked to be more than very vague! Think I tried ZIDEFS in my full size podule but don't believe it worked. It's probably just a case of hacking some addresses but I don't hav...

Awesome demo - really excellent

Loved the use of dithering and the music is some of the best I've heard on the Beeb. Even my wife was impressed

Sure, how to use productivity software is more appropriate in a secondary school. But surely word processing should be in the English class? And learning how to use a spreadsheet (when used for mathematics and logic etc) should be in the mathematics class? Maybe things are changing as this is exact...

Looking like this will be epic Sarah

Agreed - it'll be great to see such a seminal game on the Beeb

I love the look of these games. A few months ago, I briefly wondered whether it might be possible to build a Beeb version using the Pi co-pro and NuLA.

I decided that I lacked the Lua knowledge. Perhaps someone else would be up for the challenge?
