Thoughts and ideas on designing and building a Homebrew QL

My thoughts and musings on the design and possible building of a DIY / homebrew Sinclair QL

Specification:

68008 CPU (HD/MC68008P12) 12Mhz Max.
512K SRAM or more
64K,128K EPROM
CPLD to emulate ZX8301,ZX8302
Modern MCU to do ...

That's a nice list. :)

There's a couple of specific items I'd be grateful for. Would you be interested if I paid shipping to Texas, USA?

The GALs and the 1772s.

Sorry, couldn't handle the British weather any more and quit ;)

I may only have WD1773s left..I'll have to check. I believe these ...

** More FREE ICs... to Good Home !!


Are you Building a Homebrew Sinclair QL?

If anyone is interested in design and building their own Sinclair QL ( or is already doing so) Then I can offer FREE ICs.


I have Integrated Circuits (ICs) like :

MC68008Pxx DIP48
MC68901 MFU
MC68230 SIO
MC68681 ...

Has anyone put the QLs ULAs onto a CPLD ?


Putting QL ULAs onto a Complex programmable logic Device (CPLD)?

Has anyone put the functionality of the QLs ULAs (ZX8301/ZX8302) Chips into VHDL/Verilog Code which could be used to programme a CPLD?
If so how many Macrocells/logic blocks are needed ...

All Gone !!

The ICs have now all gone (or will) be going to a good home.

Hi.

CPLDs...Free to Good Home

I have a handful of surplus CPLDs (Complex Programmable Logic Devices) EPM7128SLC84-15s and EPM7032SLC44-10s . Anyone that is interested in learning VHDL code/logic programming may find them useful as 'Glue logic ' in designs. These will work with 5V TTL logic ...

Hi.

Free to Good Home.

I've got some surplus 68000 ICs and stuff... if anyone wants them for Retrobrew projects etc then just email me.

(Note 68000 ICs are in PLCC package):

68HC000FNxx PLCC68 1pcs
68010FNxx PLCC68 1pcs
68008FNxx PLCC52 1pcs
68901 PLCC 1pcs
68230 PLCC 1pcs
68881 FPU PLCC 1pcs ...

Sorry No PCB .. but at the price you can't really complain..

.. Just ICs, some D-type sockets, PS/2 keyboard connectors, switches, LEDs 7805 reg etc

They are aimed mainly at those interested in electronics and possibly building their own homebrew machine and learning about microelectronics on the ...

these kits are aimed at those with an electronics or technical background (or those willing to learn) whom wish to make/design their own 68000 machine..possibly a low cost Sinclair QL. Thus learning about how to design and build your own microcomputer system

The EPM7128 can be programmed to decode ...
