Re: ADFS multi platform/multi target + faster IDE FS

Thanks Ken, I'd somehow not spotted the Simon had documented all the commands in such detail - that is a big help. I'll try and get hold of a beebSCSI board or get some PCBs made up. I've also managed to get a faster IDE build for the master. I've not put this up on GitHub yet but I will after I've ...

Re: ADFS multi platform/multi target + faster IDE FS

That would be perfect thanks Rob. I'll have a go at getting an IDE build for the Master - might be a couple of days - I've got a Master here but it will need recommissioning. Do you have a real cheese-wedge 6502 copro (or anything else?) to try out on. I'm not sure the fast tube stuff will work with...

Re: ADFS multi platform/multi target + faster IDE FS

I've ordered a scsi2sd from AmigaKit - I got a 5.2 in the end, hopefully it should do what I need! D PS: I didn't mean to imply there's anything wrong with the beebscsi or pi1MHz solutions I'd just like to have as wide a range of options to test against as possible and I'm hoping the scsi2sd will be...

Re: ADFS multi platform/multi target + faster IDE FS

Thanks both, Rob, I think I want to get my own SCSI solution but I may take you up on the offer of a loan if I can't get a real scsi2sd for a sensible price! I'll be in touch by email about testing the IDE+ADFS+Fast are you on a Model B or a Master? I've only built the fast IDE for a Model B so far ...

Re: ADFS multi platform/multi target + faster IDE FS

On the scsi2sd front so you have these for sale or know where to get them? They seem to be rather expensive on ebay... the Australian markets don't seem to be exporting at present.

Re: ADFS multi platform/multi target + faster IDE FS

Thanks Dave, I'll have a read of that tonight.

How close to the Plus3 hardware is the Pegasus? Are all the hardware registers the same?

I'm a bit of a noob when it comes to all this Electron stuff...well maybe not a noob but my 48 year old brain has forgotten all the stuff I knew when I was 15!

Re: 34 way port doubler

Oh, that's a nice idea. I'm interested but I'm not sure what will happen if you "Tee" from the 1MHz bus with terminators - you'd probably want terminators on both ends but then would the signals be overly loaded?

Thanks both. I thought I might be missing something clever in ADFS. Thanks for the encouragement. My reasons for using IDE were purely utilitarian.

Thanks BeebMaster,

This is a big help, am I ok to include it in the ADFS sources - I was thinking of adding a tools directory.

Do you have the previous version too and I'll check the two for any other corrupt characters.

Anyone know what this is?

I just found this in a box of assorted stuff I got given.

It's marked 'Research Machines PN11570' and has a z80 cpu and mb8877a fdc. Unfortunately there's two chips that have already been harvested one 40 pin and another 28pin (rom?)

Is it worth resurrecting?
