Re: Renovating my original BBC B

I knew I was being too hasty when saying the machine works. It mostly works, and I was getting annoyed by the lack of ROM sockets on a stock beeb so I tried plugging back in the APEX ROM/RAM board, which involved taking back out the 6502 CPU and 1770DFS board, plugging in the board and putting those...

Re: Hi from an avid BBC Micro supporter

Thanks for the info. Most helpful.

I took the plunge and tried both BCPL ones, and imaged both of them and compared the files, and they are identical.

The other two (I haven't tried them) I'm happy with being BASIC, and it's just as well I didn't try plugging in the RAM.

Re: Hi from an avid BBC Micro supporter

Bringing up my first post on here where I introduced myself, I have an IC storage box. Now I've installed my new BeebZIF I can start imaging some ROMS. I have several ROMS without windows on top which I need to identify. All I have to go on is the text on the top, so I'm going to write a list here, ...

Re: Clwyd Technics Colour Palette enhancer

I was going to dump the Colour ROM last night but hit a snag. I can't remember how to save an image of a ROM. I'm sure I've seen a small BASIC program to type in, even without a datacentre plugged in to save onto floppy, but I'm blown if I can find it. See https://stardot.org.uk/forums/viewtopic.ph...

Re: Renovating my original BBC B

Well, she lives. All I ended up doing was changing the keyboard connector on the board and now it's up and running. I'm not totally sure it's fixed completely (some strange rising background noise on the speaker, for example), so before I start adding stuff back in I want to do some more checking, b...

Re: Renovating my original BBC B

Being an Issue 4 Board, I would suspect that you have (a) severed leg(s) on the CPU Socket, between the socket and the Board. I will bear that in mind but I'm unsure how to proceed. I guess I could beep out the socket with my multimeter. One other thing I've noticed while looking at the solder side...

Re: Renovating my original BBC B

I am almost giving up on this board. I struggled most of the day with nothing but the first 'beep' or more precisely random sound, and couldn't get further, so out of desperation I took out the 6502 and re-seated it, to briefly once again be met with a boot up screen, albeit still with the random no...

Re: Renovating my original BBC B

I wonder what the magazine at the time of the Bodybuilding article says on the matter. I'll take another copy of the ROM when I get chance (my focus...

Re: BeebZIF kits now available

Hi. I'm not familiar with that board, so yes try it in an original socket. I presume you're powering off the machine, fitting the ROM you want, then turning it back on again, and not fitting the rom with the power turned on? Thanks, Mark. Yes, that's correct. I'm switching off before putting in a R...

Hi Mark (RetroClinic) I installed the BeebZif socket into my Beeb last night but I don't see any ROMs showing up in *HELP. I chose to plug the 'ROM' end of the ribbon cable into my ROM/RAM board. Would that be the reason for it not working? I'm going to plug it next to the OS ROM to see if that make...

Is the Chameleon ROM available anywhere? Presume it's http://mdfs.net/System/ROMs/Display/Chameleon/ but is a bad link.
I thought I had an image of my ROM, but I can't find one. I'll have to fire up the machine with the datacentre plugged in and export it.

I note the switches you installed on the right hand side for 40/80 track selection. What was the "colours" switch for? The colours switch was for the Colour Chameleon board (a Micro User Bodybuilding article by Mike Cook) which went between the RGB output and the Monitor. You programmed in (via the...

Re: Turning a Music 500 into a Music 5000 but with a switch to revert the change

I wonder if there's any way to convert programs for Music 500 to the Ample ROM format.

What are the differences?

Presumably the ROM has more commands. I guess I need to start reading the manuals.

Ah, so the only difference is whether I am going to be using it on a Master or not. That's useful to know.
