Re: Help please - resurrecting model B

The test ROM goes in place of the OS Rom.

It should be the ONLY ROM in place

Re: Help please - resurrecting model B

In the end I have sent you my actual own EEPROM with the test ROM on. I've been up to my ears in other stuff and didn't get a chance to blow a new EPROM. It went in the post this afternoon but I think it will get 'picked up' tomorrow from the post box. In theory it will be with you Saturday hopefull...

Re: Voltamace/Videomaster Database Games Computer

Interesting, so they seem to be on 2716 EPROM...

Which means I can read them, and produce new ones.

Which is nice.

If I socket one cartridge I should only ever need to use one. Especially if I use a ZIF...

Cool.

Re: Voltamace/Videomaster Database Games Computer

Yes, that makes sense.

Was just curious as to whether it had something akin to a boot ROM image or similar as the processor is in the main unit.

Thanks.

Makes sorting it out a little harder I suppose.

I'll open a cartridge this evening and see what's inside.

Evening all. So, I acquired this old beasty in a job lot with some beeb stuff. I've opened it up and looked at the 80's bugs etc. So, it is a Waddingtons Videomaster/Voltmace Database Games Computer.

Re: Quick look over this BBC B

Is strange to see so many of the sockets replaced with those red ones though. So far in all my Beeb's I've not had to replace one of them. (although I've added them for new RAM IC) As Sweh says, is a fairly standard Issue 4 board. Worth a look for that floppy drive, but more to the point, the floppi...

Making a few changes to EEPROM/EPROM programmer

Ok, so when I bought my EEPROM/EPROM programmer I didn't really know what I was doing etc. So when I found that I couldn't program most old ROMS as the voltages were higher I was a little crestfallen to say the least. I managed to obtain from eBay (as well as swapping a few with Kazzie) a few ROM's ...

I tried again in the light of your helpful comments. I have established that the Basic ROM is OK, as it works in the other B. I have tried the Basic ROM in all the other sockets without it changing anything. Do you have any further suggestions? Do you have access to an EPROM programmer? If so then ...

Re: Games on ROM

Ok, this is cool. Chuckie is my go-to game when I have five minutes, so I'll definitely be burning that one. Is there anything fancy about putting a game on a ROM - if it's compiled code will it 'just work' when burned to an eprom? I think it will show up in the list of ROM's via *HELP and you can ...

Yes you are correct it's for the 32bit Risc OS machines, as the ROM image is available from John K's site wiping it isn't a problem so get it wiped and stick something useful to you on it.
Already wiped! I'm thinking something far more useful, like Chuckie Egg I think.

EPROM programmers can be fun. It took me a while to work out what on earth I was doing with it. As for working with soldered IC's there are varying opinions on how best to remove them. Cutting pins first, then desoldering each leg individually seems to be the most recommended way of doing it. Again,...

Re: Someone's pinched my econet! (Now repair help!)

I can't share much wisdom on this.... Acquiring one of Tricky's test ROM's would certainly help with finding the rogue RAM IC. As for piggybacking.... As far as I can tell, you would not get consistent results with this as it is likely you would get random results on which IC was actually being acce...
