Also, pr0f... Propeller driver? Do tell!


Early doors project to provide a spin program to handle QL / Spectrum network - it was part of my IPC replacement idea, but it could be used standalone to make a networked peripheral for instance...

Awesome work - I may steal the timer idea to get QL networking driver written for the propeller if you don't mind?

Re: ICL OPD

keyboard is very weird - I actually have an ICL OPD keyboard from long ago, which I picked up from a surplus place in Bedford when I lived there. So I can spend some time bussing out the matrix - the actual keyboard matrix driver is using one out and one in 8 bit shift registers - although I think t...

Re: ICL OPD

Some other mods i am considering: I plan on changing the address decoding on the CPU module so that the ROMS occupy the first 64K/96K/128K address space Remove the 2 Sinclair ULA's carefully, and solder in sockets and do the same for the databus transceiver and address mux's too - means I could pote...

Re: ICL OPD

Not sure if this is considered a compatible, but it does share some common hardware components. Acquired a motherboard and processor board for this recently - does anyone have a service manual or circuit diagrams for this beasty? Or perhaps have any details for the pin outs for the ROM card at the ...

Re: ICL OPD

I know - it's a bit of a lost cause. I know it was marketed as a Merlin Tonto M1800 - and I came across this little gem: http://www.binarydinosaurs.co.uk/Museum/icl/murraywriteup.php and there is a link to this manual: http://www.samhallas.co.uk/repository/po_docs/tgn_0031_merlin_tonto.pdf which giv...

Re: ICL OPD

It certainly has some QL pedigree - featuring both the ULA's from the QL :-) Also 2 microdrives. It's a different OS though, and had it's own bespoke monitor which also powered the board. I am wondering how much work would be involved in making the board work like a QL, but in any case it would be a...
