Stellar GS-1000 Graphics Computer

Remind me to show you the manuals for my I2S 'image processor and display' units sometime. Late 1970's vintage, loads of TTL (a few thousand ICS!) and DRAMs The resolution is not great by today's standards (512*513 pixes, 24 or 30 bit colour), but they have some interesting features, like the 'feedback ALU' (regard 2 of the byteplanes as a 16 bit 'accumulator plane', then combine (essentially any of the functions available from the 74x181 ALU chip) the contents with the contents of another byteplane, the result going back to the accumulator). And I should also show you the manual for my HP1350 'Graphics Translator'. A device that takes in simplified HPGL over an HPIB interface and outputs X/Y/Z analogue signals to a vector display. The interesting thing is that it's all done with random logic, there's no processor, or anything resembling a processor, in there. -tony
