More nostalgia… A few weeks ago I bought the, RC2014
compatible, SC203 Modular Z180 Computer Kit for RC2014
kit on Tindie which uses the Zilog Z180,
512K fast static RAM and 512k ROM (loaded with ROMWBW).
To this I added a Compact Flash Module
as well for mass storage. With these components it’s possible to create a CP/M
compatible system (just add a terminal) running on real hardware of that era.
A few years ago, Elektor Magazine had an
interesting DAC project
with high end aspirations based on the Burr-Brown (now Texas Instruments)
1794 DAC for a modest price.
I got in a nostalgic mood lately, thinking about the long gone days when I
made a Z80 slave CPU for my BBC model B computer and ported CP/M 2.2
(and later ZCPR3) to it as well.
I found this definition on the website of Radius Power:
Despite the fact that the headphone amplifier really sounded very good (it’s
incredibly fast making my headphones sound more like electrostatic headphones),
I wasn’t really happy with the measurements I made with the
QA401 Audio Analyser.
