I, too, sometimes get nostalgic for the "heady" old days of computing. I
started in the late 70s with hand-coding programs on an Intel 8080
system. I then graduated to CP/M-80 on an S100 Zilog Z80 processor
system. I then built my own PC-XT from components in the mid 80s and PC
technology has been progressing ever since. I keep a MS-DOS computer
around to talk to a device programmer with proprietary DOS-based
application software, just in case I need to program an EPROM or PAL
chip. I still think the Cromemco Z-80 Macro Assembler which ran on
CP/M-80, is the best macro assembler I have ever used, so I created a
CP/M-80 Z80 software emulator which runs on my Linux desktop, just in
case I have a need to assemble a Z-80 program or maybe run a CP/M-80
program or two. That emulator runs so fast on my desktop that a fairly
large assembly is done virtually before I can release the Enter key.
Would I go back? Heck no!
I made a lot of international flights in the mid 80's with a Phillips
portable computer. It was badged version of an Osborne, I believe. It
was more of a luggable and weighed a ton - it crippled the shoulder on
anything more than 100 yards walk. I used Wordstar on the CP/M os and
the screen was a very small monochrome crt but it did have dual 5.25"
Later, when early pc look-a-likes were available, I actually installed
and tried Windows v1 for an afternoon before uninstalling and dumping
the disks in the wastepaper basket to go back to WordPerfect under DOS.
Those were the days !!
