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...

Re: Hermes status
although the ipc dissassembly I have has addresses against the dissassembly - so is also quite useful.

Re: Hermes status
The 8049 should be readable using 8049/8749 using the HiLo programmer. However there is an IPC project on GitHub I think, which has a binary file with it. I compared that with the one Derek put up on the thread - and for the most part it would seem to be the same source, but there is an additional b...

Re: Still possible to get Minerva ROM
so looking at those stripped circuit boards - the chip under the ROM was a 13 Input NAND gage - so presumably used to do the finer address decoding for the SDA / SCL Using a 7430 (8 input NAND) would have been enough, SGC allows direct access through to $BF80-BFFF. Here's something I wrote a few ye...
