Last thing: does anyone know the difference between the A7A ROM and the A8? ?I've not
found anything different; I assume it's probably an obscure bugfix.
On my CQD-220/TM with original CMD labeled EPROMs I have F220Y1A8 /
F220Y2A8. Is that the same A8 version to which you refer?
I also have .HEX files for a CQD-220/TM B2A Release 06/24/94:
220Y1B2A.HEX
220Y2B2A.HEX
And a CQD-220/TM B3 Firmware 09/23/94
F220Y1B3.HEX
F220Y2B3.HEX
I wonder what is different between the A8 and B2A and B3 versions. I
don't think I have ever tried loading the B2A or B3 versions on my
CQD-220/TM.
