The Model 30 was apparently one of the most popular machines in the early
days of S/360. Being able to build such small machines was a strong
commercial consideration for the company, and thus the architecture.
at end of semester after taking two credit hr into course, was hired to
rewrite 1401 MPIO for (64kbyte) 360/30 ... which was running early
os/360 PCP (single executable program at a time) ... had 2311 disks,
tapes, and unit record. I first had a 2000 card program, assembled under
os/360 but ran "stand-alone" ... being loaded with the "BPS" loader (had
my own monitor, device drivers, interrupt handlers, error recovery,
storage management, etc. Making changes during development & test
required brining up os/360 and re-assembly and then stand-alone loading.
I eventually got around to adding os/360 mode of operation using
assembly option to generate either the stand-alone version or the os/360
version. It turns out the stand-alone version took 30mins to assemble,
however the OS/360 version took an hour to assemble (OS/360 required DCB
macro for each device and each DCB macro added six minutes elapsed time
to assembly) ... aka stand-alone testing and then re-ipl for OS/360
30min re-assemble still took less time than OS/360 testing and hour
re-assemble.
