a quick test with the unscrambled ROM shows it does load the banner and the eprom keyword is there - but typing it hands the emulator, as the hardware doesn't exist

The ROM in the QEPIII is 'jumbled' so if you read it using another eprom reader it will make no sense as a QL ROM, - if you sbytes the ROM when the card is in the QL, it will give you a valid ROM - I believe there was a program on Dilwyns site to unscramble the ROM image to a standard ROM layout.

I think you should be ok to use a 2764 chip in the interface 1 from what I remember - would have to take a look at the pin out and circuit diagram to see if any specific requirements for that ROM version. Actually just did a quick browse for the 2564 pin out - and it's different - so that won't work...

The QEPIII is not compatible with either SGC or GC or any clones of those - because they lack the 'E' signal which is used by the QEPIII board

The images are working for me...

I meant to share this the other week, but I now have a Colour Maximite 2 computer, running MMBasic. cmm2.jpg You can read about the CMM2 here: https://geoffg.net/maximite.html And the unofficial support forums are here: https://www.thebackshed.com/forum/ViewForum.php?FID=16 Basically, a switch-it-o...

To my surprise, a QL mainboard replacement still leads the poll. :o Could some of those who voted for it, tell if they still need the QL extension bus? Please reply under the assumption that lots of RAM, fast mass storage, mouse interface, SER, etc. are on the mainboard. If the motherboard also run...

Love that Sam Coupe!

The VMap is an excellent addition to the Vdrive. Thanks for the video - it gives a good demo of the Vdrive!
