But one of the first. But the Z80 is still “more alive than all the living”. Not the one the Z80 CPU itself, and its core is active in trunk system controllers HD64180 is used, in AMPS cell phones from Ericson/Uniden the host also has a core z80.

Line address counters for SIMMa regeneration are included in the chips in it installed, so the value on the address and data buses during regeneration doesn't matter. First CAS then RAS (WE in 1), the main thing is that the frequency regeneration was more than 500 kHz. In any case, to the Spectrum (computer on the Z80) SIMMs up to 4Mb were connected in this way. VB> Well, this is nonsense (audio delay on VB> z80)initially... Audio latency on the Z80 may be of theoretical interest. Besides on the Z80, not only reverb, but also almost any audio effects in real time, such as flanger, pitch up/down!!! to any height, distortion (digital), etc. I did it myself when I was programming on Spec. About three years ago. ADC for 1113PV1 and DAC for 572PA1. Everything worked at ~30kHz. At frequency Z80 - 7mHz. Everything is in real time. g0oD LucK Vladislav !!!
