Re: How to Health Check My BBC Master (128/512)

It's been a few days, so here's the latest ... I'm mostly happy that the Master is working. On and off I've been testing the various discs I've got to see which are in working order. And that's where my current puzzles arise. The same disc can go from working to not working and back to working again...

Re: How to Health Check My BBC Master (128/512)

Thanks RobC, No, no EPROM programmer. The only other bit of kit I have, which I can't see being of use here, is a CARE SMART Cartridge (with the red button) ... though I'm happy to be corrected on that. I remember using that to avoid loading things from tape and to create my own "save points". After...

Re: How to Health Check My BBC Master (128/512)

Thanks danielj, they look like handy devices. Turns out that even method 3 is problematic as my remaining 3.5 inch discs are HD rather than DD. However, I'm wondering how necessary it is, especially as I don't intend to keep the Master (if for no other reason than that I don't have the space). So, r...

Re: How to Health Check My BBC Master (128/512)

Thanks danielj

No joy with OmniFlop as I only have a USB Floppy Drive for my PC (haven't had an internal one for years). However, when time allows I may try that site's third option.

Re: How to Health Check My BBC Master (128/512)

Keyboard cleaned and one of the three dodgy keys is fixed. One I'm not too fussed about (the * key on the number pad, which can be typed differently and will work if you try hard enough). The other I'm more bothered about. It's the "Z" key. Obviously anyone who wanted it for retro gaming would find ...

Re: How to Health Check My BBC Master (128/512)

New CMOS battery (c/o of Mark at RetroClinic) and jumpers (c/o RS Components) in place, and the Master seems to be behaving itself pretty well without the AA Board (well, Elite plays at least). Will be cleaning the keyboard and then trying out some of those GEM 512 disks. Not sure I've got it in me ...

Re: How to Health Check My BBC Master (128/512)

First three voltages checked and all seem fine. Hard to get at IC11, which I believe is beneath the 512 board which is itself very securely attached. I've no idea about testing the 512 board or co-processor. I do have the 512 discs 1 to 4, which I guess may be of use? I may have a play with those la...

Re: How to Health Check My BBC Master (128/512)

Thanks again RobC,

Jumpers had been my only thought but I didn't trust my guesses enough to even mention it. But you appear to be right. I found this guide which says where I need to position the jumpers. Now I just need some jumpers as those have understandably gone missing.

Re: How to Health Check My BBC Master (128/512)

Thanks RobC et al, Given that the machine doesn't currently remember config, I was surprised that with the AA Board disconnected, it didn't automatically revert to ram in slot 6. And when it's disconnected the *HI command won't be available. Any thoughts? In terms of selling, is it worth taking the ...

Re: How to Health Check My BBC Master (128/512)

Thanks RobC, A quick Google revealed it is indeed a Morley AA Master ROM Expansion board . With that identified, I found the instructions and properly installed it (it was previously sat loose instead of connecting with the ROM slots below), I was then able to use the boards *HI command to set slot ...

Re: How to Health Check My BBC Master (128/512)

Thanks guys, Two pics. One the main board (plus 512 board, I think), the other another expansion board (unless that's for the 512 but I think not). https://lh3.googleusercontent.com/_RE3nH8tbcQ0oXRwlXLxxBf1iwph0b-zk5rbqcz2KYPuCNqYa5Q1ckbSxuPqNwYcG-kCehIp-7vuPOOrRu0op2gTU9bH__mJjP9wzDN3Mta0yqwCXlOFg3...

Re: How to Health Check My BBC Master (128/512)

Thanks Mark, I do indeed have a multimeter. It doesn't get out much, but I know how to use it (that had been my father's too at one stage). What to test with it is another question altogether. On using the multimeter to test my battery pack, it wasn't happy. The individual batteries are fine, but th...

How to Health Check My BBC Master (128/512)

Hi there, I recently inherited my father's old BBC Master. It was originally a 128, but was upgraded to a 512, I think. I played games on it as a kid, so it has some nostalgia factor for me, but I don't have the space keep it. As such I'm not looking to keep it, but would like to get it into full wo...
