Re: Open source firmware for Gotek floppy emulator released

80 track, 10 sectors, 256 bytes, single sided, interleave 1, skew 0, bitrate 250000, RPM 300, Auto-Gap3, pregap 0.

It seems fine with 1770 on the master - it could be it needs tweaking on an 8271...

Re: A5000 and A7000 guide needed

Cut the batteries out with side cutters or anything that will cut the legs off them (e.g. https://www.ebay.co.uk/i/302296865655). Will follow up with replacing tomorrow. Get them out now, however!

Re: BBC Master Issues with Replacement CMOS Battery

Are you sure +ve and -ve to the motherboard are the right way around?

If so, the next suspect is the CMOS IC itself... (HD146818)

I've just finished adding ADFS disk image support to FlashFloppy in my fork, Keir's looking at pulling it into the main branch - if anyone would like to test it please have a go (not added DFS support as single density isn't done yet): https://github.com/drdpj/FlashFloppy ADL= ADFS double sided, int...

Re: OLD DATA RECORDER INFO REQUIRED

If you can hear it on the tape, check that the cable's OK (continuity between EAR and the right pins on the DIN plug - if you have a multimeter, you can do that by setting it on its lowest resistance setting and seeing if there's very little resistance between the two) and if that's OK, I'd start by...

Good luck! Pictures of how you get on! :) It doesn't need the clip to work at all. Fine without - that just slightly helps in removing the module.

Re: 2x non-functional RiscPC mobos - for cost of postage

The VRAM socket is a 136way D/SIMM socket. I can't find anything appropriate. I suspect it was rather rare - I can't think of anything else that used something like that myself.... :?

Because the SIMMS won't fit next to each other - just replace like with like :) (Straight up would probably work)

Well, I've pimped a gotek (total cost of all of this probably in the region of £17):

Currently, as ford said, you have to convert SSD/DSD images to HFE, but it works! :)

Ergh. my usual trick when things like this happen is to reinstall the boot sequence from scratch. I confess, I've never done RISCOS 5 on the RPC - mine sit running 3.7. Someone may have a may have a less "sledgehammer" solution to reset all the internet configuration...

Re: Problem Beeb MotherBoard

I'm going to have to defer on this one - personally I'd try and clear up the RAM fault first and make sure my 6522s were good, but there are any number of other things that could be arguing a bit - I'd probably scope the reset/clock lines to see what they were doing on boot. However, until you've ir...

Re: Problem Beeb MotherBoard

It won't boot properly with a dodgy keyboard cable connected so in the first instance I'd assume that's why it's needing a few ctrls before you catch it right... Once that's ruled out then it's time to look further :)

Re: Master ADFS problems

Yup, setting the links will remove your sideways ram. I'd leave them intact - as you rightly say, you don't want to end up with a Master 64 :) The preferred solution with the master is to use a rom cartridge.

Re: Master keyboard IDC connector

What I would do is desolder what's there, clear the holes out, trim the plastic back slightly (2/3mm - enough to get the ends of the wires through the holes and to the pads), and then resolder it. I'll just be brittle at the end where it was flexing against the PCB. It'll be fine inside the sheath. ...
