Re: Return to E2P - the Electron Second Processor

A long time ago I had an Electron (don't know which motherboard), Plus 1, Plus3, Panasonic KX-P1081 printer and E2P on which I did quite a lot of work. Worked great. It pains me to think that I sold it, particularly the E2P. :( I have reproduced the same system now except for the E2P, having Dave Hi...

Re: BBC BASIC GOTO line decoding

Interesting. For my example above for line number 30:- lsb : byte 2 EOR ((byte 1 AND &30) * 4) Is: 94 EOR (84 AND &30)*4) = 30 But msb : byte 3 EOR (byte 1 * 16) Is: 64 EOR (84 *16) = 1280 This should be zero.

BBC BASIC GOTO line decoding

Does anyone know how line numbers are coded/decoded.
GOTO30 is 229(GOTO token) 141(line number) 84 94 64
GOTO20 gives 84 84 64
How do these 3 bytes generate the line number?

Thanks,

Re: Plus 1 and AP5 new issue.

Sorry to waste your time Dave.
I have put the ADFS back into the AP5 slot 13 and set J1 closed on the AP6 - the ADFS is seen at power on and the CF card is working OK!
I presume the ADFS wasn't seated properly when I first tried it though I had tried reseating it.

Re: Plus 1 and AP5 new issue.

I have an AP5 with ADFS and IDE CF card adapter and the ADFS is not seen in slot 13 with a normal Plus1 or with an AP6 with its slot 13 off.
ADFS is OK in the other cartridge slot or a slot in the AP6.

Re: Gotek on Electron

Ray, I've been using your menu system and it's excellent. I've made a small improvement to the ADFS version though - it prompts to load from drive 1 or 2, but if you have a harddisc this fails because ADFS renumbers the floppy drives as 4 & 5. Also, being pedantic, I would number the drives as 0 & ...

Not under the correct title but the DFS games are now available from the link on the first post.
These are the compilation the disks I produced for MMC cards put back into publisher folders.
A few games' disks are in other publishers folders - the menu prompts for the correct folder+disk.

Yes, but the original HcX (not GoTek) can't, hence the above HFE files.

Re: Open source firmware for Gotek floppy emulator released

I have made a mistake. The ADF files I have come across are 320K the same as ADM files.
How does FlashFloppy treat ADF files?
I find that FlashFloppy 0.9.16a will not use 320K ADF files but after renaming to ADM it does.
