The Sinclair QL Forum

Thanks for your requests. I posted PM for everybody asked about, so please look at your inbox as it seems that the forum doesn't send notification any more. Also, it seems I will have to make arbitration between some cross combined requests. BTW, I haven't managed to insert pictures inside PMs, so I...

Hello Alain, Out of interest, are you able to show pics of the internal RAM upgrade? Was it something purchased or a home made upgrade? It is in very nice condition. HI Chris, It is an internal memory upgrade kit called ql640 I purchassed in 1988 for 101 pounds from Sector software (don't know real...

I have to sell a complete British BBQL system in a perfect state and rarely used. Including original packaging, leads, PSU and english manual (as new). The motherboard is a D14/Issue 6 layout, fitted with a JM ROM. Keyboard membrane was renewed as well as all main ICs (68008, zx8301, zx8302, 8049). ...

I have used a similar scheme to implement a big 1 mega rom (2x512) on Q40 with external selector switching between 2 bigs uncompressed SMSQE in rom.
This worked fine but I don't see any benefit to switch between 2 qubide firmwares...

Well, I am not a hardware man able to answer electronical questions but I don't see why writing x times the firmware code on winbond 512 could be a solution. Higher addresses than 16k should not be selected at all. If the board does this way, you have to bend out some adresses legs or to ground them...

Hello, If both gals are near the edge bord, I guess your board is a clone. The gal 1 is nearest ide connector and the gal 2 nearest QL motherboard connector. I am used to reprogram the gals without need new ones. Usually clone board comes with otp rom which cannot be reprogrammed and need to be repl...

You can use the QUbATA V3.10 Driver for the Clone version.
I attached below the archive containing ROM and GALs binary codes to burn.
There is also a REXT code which can be LRESPRed after having configured the base address for QubIDE hardware.
