There is another golden oldie. The 5120 was a strange beast, selectable
for either BASIC or APL. It's successor, the System/23, had an 8085
rather than IBM's homebrew but had a similar look. Familiarity with the
8085 was one of the factors for using the 8088.
Umm ... 5120 came well after the 8088. Got yer numbers right ?
The 8085 was a pretty fair predecessor for the 8088 however. Not THAT
much diff. However, for the time,
the Z80 was maybe a tad better.
Would still like to get my hands on a working S-100 Z80 system .....
https://en.wikipedia.org/wiki/IBM_5120Technically the 8088 processor was released in '79 while the 5120 was
released in Feb '80. The System/23 with the 8085 was released in July
'81. The 5150 PC was released in August 1981 more than a year after the
5120. The 5100 itself was released in '75, and the 5110 in '78. Same PALM
processor throughout. The 5110 had more I/O like floppy interfaces, while
the 5120 had a larger screen and 2 built in 8" floppies.
The company I worked for bought the 5120 and I created an inventory
control system on it but my personal machine at the time was an Osborne 1
CP/M 'portable' that I bought in April '81. I don't remember when I got
around to buying a PC clone, maybe '84? It was one of the brand x mystery
boxes with the turbo switch.
