Re: Hermes status
Here is a very interesting vendor from Poland that has several available batches of 8749 IPC chips. Ignore the first 4 which are one time programmable used, hence already programmed and not erasable. https://www.ebay.de/str/tvsatelectronic/IC-Microcontroller/_i.html?_storecat=18701871014&_sop=2...

Re: Norm's "mere" woman sentence.
It's a shame we can't use HTML like tags
e.g.
[SARCASM]The written word should be read without inflection or emotion[/SARCASM]
Personally I love a good emoticon

Re: Norm's "mere" woman sentence.
I saw it was in quotes so assumed it was meant to be taken tongue in cheek. I do have a problem with the over censoring that now seems to be creeping into IT - The product I work with - NetBackup - has the concept of a Master server - but now it seems our documents need rewriting to call these "...

Re: Backplane and other problems
looking at the circuit diagram for the medic- it also uses the same SP0-SP3 decoding scheme as the QEPIII - meaning if your backplane doesn't alter any of these SPx signals - the QEPIII and Medic disk interface are trying to use the same address. If you cut the line for SP0 on the backplane after th...

Re: Backplane and other problems
QEPIII also uses the synchronous bus signal E which is not provided by Gold or SuperGold cards.

Re: Backplane and other problems
ASL isn't used on standard QL expansions - so that could be cut with no issues. QEPIII probably expects to be at 0c0000 - but it's designed to use the slot select lines SP0-SP3 - which are all 0v from the QL - hence that default first address for the QEP card. Does your backplane alter the SP0-SP3 l...

Re: Problem booting Super Gold Card
It was a note on the aurora manuals - which is why that signal was still provided on the bus

Re: Problem booting Super Gold Card
I wonder if the use of vsync signal to the FDC is just a cheeky way of knowing the state of that signal, so you know when you are in vertical flyback?

Re: Problem booting Super Gold Card
I never noticed that before!
I know the Gold card doesn't use CSYNC signal - but I believe the SGC does - for refresh clock for DRAMS - so might be worth checking that signal is not mis-wired somewhere in the cable for the monitor...
