my first commercial computer (not my homebuilt wire wrapped 8080) was Netronics 8085 S100 Explorer ('79-'80??). It had 128 bytes - yep 128 bytes 'local' ram and 2k rom os. Booted up to a 35ASR Teletype. Storage was Cassette Tape although I could dump to paper tape on the Teletype (and read back - of course!!). Gradually added 2114 Static (whooo!!) Ram in 1k increments (1k by 4) - so 2 chips = 1k to S100 Sram board. till eventually got 4k ram. Wrote editor/assembler using op codes only at first. Was first student to get an assignment accepted by a prof at York University that was done on a home PC. Whoop-de-do.
