Elf99 - rebirth of a classic

< > What's wrong with 2114s? I've used them in a lot of projects and produ < > and they fine if a x4 orginization is handy. I have 24 of them in use < > for a intersil 6100 (12 bit pdp-8) based system. < < Any schematics? ;-) Yep! < I've seen schematics, and it's not the 6845 end of things that daunts me < it's the 1802 end, trying to adapt a 6800/6502 bus interface to the mor < limited 1802 interface implementation. Effectively it's the difference < between memory mapped I/O and non-memory mapped I/O thaat have got me. Memory mapped IO on the 1802 was trivial to do and could be used to good advantage (1861 used it for the display). < Coincidentally, I purchased a PDP-8/L at 16 for the princely sum of $35 Had an 8e years ago and gave it away, looking for another. < Still, the latch required +5.0VDC, the only part with a tight power < requirement. The latch was not fussy about power, the led portion was power hog. Allison
