Re: Still possible to get Minerva ROM

Because, Winback! :D (Other hard disc backup applications are available of course!) I didn't see any battery in the pictures & the green pot makes the RTC sound as real as a plastic apple. Wouldn't a software clock that you set at turn on do the same job? the battery is connected by a pair of w...

Re: Still possible to get Minerva ROM

It's probably also useful in correctly time stamping files you might be writing to a disk - makes it easier then to know which copy might be the latest one? and bearing in mind the stock seconds counter in the ZX8302 is probably going to have some wonderful random garbage in it when it starts - so w...

Re: MDUMP TASK ?

If it's helpful - I think you can specify upto 80K of ROM image for the first file - so you can concatenate ROM Images together

e.g. 48K QL ROM + 16K (for ROMPORT) + 16K (this would be in the first 16K reserved space - where gold, trump etc. sit) - You can't then use backrom.

Re: At last... I'm making proper PCBs for my vDrive sound board.

I have to say I was initially sceptical about this - believing it to be 'window dressing' - but on watching the youtube - it does give you that reassurance that the vdrive is being accessed - as you sometimes miss looking at the LED if you are distracted elsewhere...

Re: Aurora Minerva Boot Error

I wonder if the Aurora can be used to provide the ROM port?

Re: Still possible to get Minerva ROM

Good point Marcel - I am sure that it might be possible to find right angle turned pin headers though, so the jist of the idea is there.

Re: Still possible to get Minerva ROM

you can use those right angle pin headers on the underside, and surface solder the socket on the top of the board or displace it https://www.ebay.co.uk/itm/192214611566?hash=item2cc0e2366e:g:RyoAAOSw1~JZPeEe + https://www.ebay.co.uk/itm/143201813106?var=442134022620&hash=item21577e4272:g:ljMAAOS...

Re: Still possible to get Minerva ROM

Well, I originally drew it, but then TF took Minerva over so technically I guess it's Tony's shout these days. Is he still about? Still going strong, yes. He even resuscitated his mailbox QL recently for me to look for the Hermes source codes, but alas no luck. They seem to be confined to Lau's vau...
