Re: ISO: Motorola MDP-1000 info/software
i may have posted a link yes i k ow cctalk is lacking in image handling. maybe some day that will change. it was years back. it may be something josh has already... but maybe not. neat he found the hardware!

Re: ISO: Motorola MDP-1000 info/software
Josh I posted photo of a manual we had a long time but not too long if you want to search the cctalk here.. Also always wondered which plant built in... is this same basically as a pbp 8 or is it just that they are both 12 bits?

I see many standard Texas Instruments TTL parts in there, for example SN7475, SN7483, SN7401. But there are also chips marked SN4813, SN4814, SN4820. Never seen TI chips marked 48xx before. Also a few chips marked SN6392. Out of curiosity I tried to look them up in the old databooks at bitsavers, but didn't find them. What kind of lCs are these? /Mattis > >
