Well, that 128K was a big omprovement on the machine I *first* tried implementing Lisp on -- an IBM 1620 with 40,000 decimal digits of memory. Addresss were five digits, so a typical cons cell cost ten digits, leaving space for 4000 cons cells, less the space the interpreter took. Proof of concept, maybe, but not very useful. Lking back, could I perhaps have improved things by using four-digit addresses? Maybe the extra addressing code would have eclipsed the savings. -- hendrik > > Recently had to change my limit to 1024 MB... > > S. > > On Fri, 6 Sep 2019 at 14:41, Hendrik Boom <hend...@topoi.pooq.com> wrote: > > > I just noticed DrRacket telling me > > Language: racket, with debugging ; memory limit: 128 MB > > immediatey reminding me of the 128 K that was available on the first > > Lisp system I got any actual use from -- one I implemented myself on an > > IBM 360/65.
