I am using a PDF reader ( B&W ) that runs android 4.2. I need a DATABOOK
for say a 74H00 I got it.
Other books I am less lucky with. Right now I am looking modifying the
Small C compiler from Dr Dobbs for the homebrew computer I have (living
now on a DE1 FPGA card) . A nice 10/20 bit cpu but non standard to check
the old back issues for finer details.
There are definitely scans out there that would be better if they were made
today or even made with more care. Some things could use re-scanning.
Nevertheless, I appreciate the fairly significant amount of effort that went
into scanning things originally, particularly when scanners were worse,
computers were slower, and disk space was expensive. I am not angry at them
for not doing a bunch more work than they actually already did.
Well CD roms have been around a long time, so archiving data was never a
problem.
The real problem was
all the libraries dumping the older books for the latest windows95 c++
or Microsoft application. They are not online. Google will find a lot
books for 2018 but very few from 1975.
I am looking for bare metal OS right now, I just finished the I/O for SD
card and burned the eeproms on the DE1 card. The hardware has more than
32KB of memory but I would like see if I can get the small c compiler
in 24KB of memory with a 8Kb OS.
