As far as communication standard the System 36 supports that is listed in its manuals.
The system supports : Async Formats formats, Sync Communication Formats in either ASCII or EBCDIC formats through its existing serial communication ports.
To support others like AES Data format, Sinclair QL...
In your System/36 model 5363 message, it doesn't state much about the system configuration.
So any forum reader, should take it that the system is configured in its default state. AKA, as in a IBM AD for that model.
Your message doesn't state a II, III version so we should interpret this as a I...
I wasn't going to reply to this entry but I decided may I should as others haven't.

You should also look at the ROM memory paging system that the AURORA card used.
The old SUN 1 and 2 workstation logic designs is worth looking at if you can find a extended memory board schematic for one...

I had a Sinclair QL computer for years now and once used it lots, but it has been pack away for several years now.
Mostly do the cost of upgrading the unit and finding the...
YA, to use a Super I/O chip from an Intel based PC clone would be the ideal way to go.
Easy to interface to other microprocessors and should still be easy to get a hold of (in small quantiles).

As far as an expansion bus standard for a updated QL clone, there is some decisions to be made...
The standard IBM PC and PCXT use the following addresses for the NPU addressing (in Hex format)
0F0 Clears Math Coprocessor Busy Signal
0F1 Resets Math Coprocessor

The management at Zilog has been brain dead for years now.
By now you thing they would of had standard Z80 microprocessors that run faster then 20MHZ and had multicore capacity.
God sakes Lirpa Research Corporation in 1993 had 16 Cores in an ABBA (Advanced Bifurcated Base Aggregate) unit.

The Modify Int.. Vector is not the same one that used to modify the 100A to a 100B Level.
For this revision I can longer find the modified BIOS ROM of the Darkweb for it.
The Memory Adapter with the optional 8087 Option pictures I originally uploaded, could be different then the
ones that BIGFIX provided in there uploaded documentation. Some boards have a 541634-X-X-cX number.

For those forum users that are following this set of messages just so you know that...
After 48 years, Zilog is killing the classic standalone Z80 microprocessor chip (official notice was issued April 14 of this year)
The discontinuation list provided by Zilog in its letter includes 13 products from the Z84C00 series,

Who knows how long before they the end the Z80380...

Right On another missing schematic diagram has been found, No more manually redrawing out the PC100A 8087/Memory adapter module with all the IC Installed.
This should help speed up NA103 progress and other who want to recreate that adapter.

Ya the BIOS memory set-up settings in 100A become irrelevant when a 100B memory is installed via the 8087 adapter on the Rainbow 100A and the MEM PRES remains high.
But I I have already noted that I have other none memory expansion cards for the 100A that use the Memory Expansion Connector. So I...
