I've got a 5110 (the small 5" monitor, no tape drive) w/basic and a 5120 w/Basic and APL (big 10" and 2 8" floppy drives). The 5110 worked last time I tried (about five years ago, now) and the 5120 did not, but the CPU cards from the 5120 could be swapped into the 5110 and I believe I tried it and that worked (giving you APL on the 5110). -b -----Original Message----- From: Eros, Anthony &lt;Anthony.Eros(a)COMPAQ.com&gt; To: Discussion re-collecting of classic computers &lt;classiccmp(a)u.washington.edu&gt; Date: Tuesday, June 29, 1999 1:55 PM Subject: IBM 5100 sought << Apologies if this was posted twice... >> Gang - I know they're highly sought-after, but I'd really love to snag an APL-capable IBM 5100 and thought I'd throw the question open... There's something about those systems I always liked (even though I didn't use one more than a couple of times in high school.) Is there any chance that I might be able to tempt one of you elusive 5100 owners with some combination of the following? Apple Macintosh Portable (with case) There'd be some shipping issues, but I'd even be open to parting with an IBM 1130 (missing keyboard, power supply and drum disk.) Any interest?
