The Sinclair QL Forum

Just amended my post with the link to the online manual - you may be in luck with inkey$

Are you creating a flat 1 x 4096 character array? So each byte of your 4K file represents an element in the array? I thought inkey$ on the QL could handle non ascii characters? My question would be - can it handle all 256 possible values you might expect? https://buildmedia.readthedocs.org/media/pdf...

I think this will be it for a while - updated the address map with more detail and some corrections. Tidied up the ULA3 table and made corrections What the schematics call EXTINT is not EXTINT on the ZX8302 - which disappears off to the part of the board near the phone module - and is probably used ...

And still a mistake - what I thought was an /OE pin on the 2K RAM is actually a 2nd /CE pin - so read and write are gated by FC2

Another update to the decoding - ULA3 pins now fully deciphered.

Latest version of the decoding pdf - corrections for pins 27/28/29 on ROM Slots. So pin 27 is the ROM Slot enable - tied by resistor in the ROM module - this enables the PLA to decode the ROM slot - the OPD will then check the slot for a valid ROM header and if found - add it to the OS tables. Verif...

I picked up a 4 port ROM cartridge with PSION - it's in 2 ROM chips, so I am assuming I may have the 2.5 version - I will upload the images when I get chance. I suspect the reduction in ROM chip count is what allows the 2 extra decode lines to be made from the PLD.

Did you get the ROM image for this recreation Stephen?

should be more than adequate That gives plenty of extra for any plug in cards too.

The term binware for me is items in perfectly serviceable order, but for instance in this case - the external disk was failed, the item thrown already - leaving a perfectly good power supply looking for a new home.
