So, with any luck we shall find out from the source; espcially as there is NO documentation on the website.
Why not just read the changelog, in the latest download? It's barely changed since 2003, just been rebuilt to keep running over the years.

Re: MAME: Internal ROM/RAM expansion boards

One question I have, is there a configuration option available anywhere to emulate the B32's start-up link being set to ON? Would be great to have that so I don't have to remember to *XON to get the increased memory available in InterWord, etc. The start-up link is currently not implemented, as I d...

Re: Kenda "The Professional" DMFS

Attached is an 8KB binary for DMFS 1.04, please check this runs OK. Regards, John Looks good, many thanks =D> 0459.png Edit: Even though the ROM looks good and runs in MAME, it doesn't want to access the floppy drive so seems to be different from the earlier release. More investigation required.

It looks to be the same as what people have already posted but can dump if you want.
Thanks for checking, and agree that it likely matches the 2.0 already dumped.

Re: Model Master 128+Acorn Z80 Second Processor

I've setup a 20MB SCSI drive, and with HDMAN have created two 8MB partitions, which boots nicely with the 2.00 ROM. How is CP/M typically used with a hard drive? With the 12 Acorn CP/M floppies would it be typical to just PIP them all to drive A? Or maybe use drive A just for the utilities, and copy...

ACW ADFS Utilities

This is likely quite rare but does anyone have the ACW ADFS Utilities floppy, as described in the ACW service manual?

It's basically the usual ADFS Utilities but also contains a Winchester formatter and utilities to archive files to/from Winchester to DFS/ADFS.

Hi,
Finally read EPROM (as 2764, no need to attach wire to CE pin), as attached. Not sure what version this is.
Many thanks for this, it looks good. It's 1770W V1.28 where W is for Watford, and it's dated 1986 which is later than all other versions archived.

However, my understanding is that this sector by sector raw dump is exactly what both Arculator and Mame use, except RiscOS under either emulators doesn't recognise the disk as valid ("Disc not understood").
Can you attach an example?

It looks like MAME implements multiple fonts depending on type of 6847 (PALS, NTSC, T1, etc.), as to whether they are correct I wouldn't know. The CoCo and Dragon communities do use MAME, and would've expected some comment from them if there are issues.
