[TriEmbed] 68000 nostalgia?

[Mike Lisanke]

I wanted but couldn't yet afford a MIT's Altair 8800 with 256 bytes of
memory and a front panel with toggle switches and a line of single-LEDs. :-p

my 1st system was Exidy Sorcerer with Z80 and 48K RAM and 4K cartridge
ROMs... it had a audio tape interface with I/O to drive the record and
playback input and S-100 bus which I eventually added a 64Kb 1-sided /
128Kb double sided Floppy Drive... I assembled a hand-coded bootstrap
loader for DR DOS and had a bootable DOS system for many years.

I had many uP SBCs but none had 2MB or any MB :-p (6800, 6502, RCA Cosmic
Elf (cpu?), 68000, 8088, 80186, etc). Most had at least a keyboard and
display interface (some only 7-segment LED) some had only I/O with which
you could add a hexadecimal keyboard (popular w hackers). Nothing like a PC
and no real way to upgrade like the Exidy.

I had an Atari 800 (6502, 64Kb memory?) which I used with Basic, Assembly
and Forth... and wrote an APL Terminal editor for work at University. :-D

I had an Amiga (68000 I think) with 3.5" floppy drives and I think 2/4MB
and co-processors which did some very real-world stuff.

Never bought an IBM PC/XT or AT or Any even though they gave me plenty of
opportunities... But eventually had Gateway 80286 80386 systems which were
cheap and ran DOS + Windows + dual boot Linux :-D

Early computing took a lot more learning to do useful stuff, but; was a lot
of fun!!!

I'm still not nostalgic for older processors ... we have ARM chips which
are kick-a$$ architecture compared to older processors and skills are
applicable to higher end ARM systems... And you can alway QEMU some older
CPUs (6502+68k) when you want. There's still some great games and good
simulators for them that run great on a modern processor.
