Yes!

Earliest experience SWTP. Bootloader binary from switches to run a cassette

file loader.

Vaguely remember an IMSAI something, Believe it was 8088. Also a weird little strip printer

in a wood side case with smoked glass cover that went with either

the SWTP or the IMSAI.

Commodore PET “Chiclet”, still have it, run issues.

Ohio Scientific Superboard used as an embedded device

for alarm system printing. Still have one, haven’t run in years.

Dual 5.25 floppies in case that were connected to Superboard at

one time in office. Most of what we did was cassette loaded due to

field volatility of disk drives, (heavy handed field personnel).

8088 dedicated processor for audible coding of fire system

and graphic LED displays.

Various DEC over the years. 11/23 comes to mind. Think I still

have manuals in a drawer with schematics for older DEC equipment

here somewhere.

Data General Micro Nova used as a central Station monitoring system.

Have the processor, lost the 10 Meg disk drives. Big on serial ports,

All printers and terminals were serial LSI’s. Had one of those for a while,

Eventually caved to “wife” and got rid of the terminal.

Various embedded 8749 machines over the last 14 years. I tend to

do the hardware and another gent here writes the code.

I learned in 6502 machine code, completely missed the assembly era.

I have no idea where I was. Then jumped into various compilers.
