It would be great to recover these - whilst lots of games have been preserved, there's a fair bit of "serious" software that's still MIA. I posted an advert for the Brasscourt compiler and a probable link to the still active company here . Might be worth trying to contact them to see if they still h...

A Google search has given that SWP appered with ARMv2a and deprecated with ARMv6. However it is not easy to find the exact years. The ARM3 was ARM v2a and definitely came out in 1989 so I believe that's the earliest date for an available ARM chip with SWP instruction. There is something odd around ...

SWP was implemented in 1992.

Didn't SWP come in with the ARM3? In which case, I think it would have been 1989.

but let's not forget the unreleased ARX which was what Acorn intended to use, but which wasn't looking likely to finish in time (or at all), and so ARTHUR was born. Have to admit that I'd forgotten about ARX :oops: Was it Unix like? There's a list of Acorn's operating systems here . Of course, ther...

If you get a chance to test it I would be really interested I'll put it on my list of things to do when I get back... I've got a couple of I/O podules and an A440 that's sitting around doing nothing so it'll give it something to do! I should also have a ROM podule which is supposed to work with 65H...

So I am very curious why did Unix miss Archimedes in the 80s? Umm, it didn't: http://chrisacorns.computinghistory.org.uk/Riscix.html I have a (currently sick :( ) R260. It has 16MB of RAM and an FPU. When it works, it's quite good fun! I believe there were other Unix-like OSes for the Arc - I've se...

You can get podules that contain some of the Beeb's ports including the 1MHz bus e.g. the Acorn I/O podule . According to this , 65Host will trap 1MHz bus accesses and redirect them to the I/O podule hardware. However, I haven't tried any of this and am away from my kit at the moment so can't test i...

Mark Haysman (RetroClinic) has done a video on Youtube showing how to remove a security mark from a Cub.

He also mentions repainting Cub cases in the description so it might be worth contacting him.

It gripped the paper with small gears and if you went up and down over the same bit too many times, it made holes in the paper and the paper stopped moving. Doesn't sound great! On the subject of old printers, I dusted down one of my Integrex 132s a couple of weeks ago to make an 8ft banner for my ...

I have one of those in the loft somewhere. I've even got new pens for it but haven't tried using it with the Beeb.

I'll have to dig it out and give it a go!

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,

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...

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 ...
