But this thing is specific to posts from people on the west coast, it more or less happens with all of Eugene Miya's posts. It happens with around 1 in 5 of the Wheeler posts. I get those around 36 hours late, but I can get replies to them within seconds. I get Rick and Barb's posts within seconds. I have two ISPs, one personal and one corporate (mostly for tax reasons, but also for redundancy) and use both their newsfeeds; plus a newsguy and a dfn read-only feed. The ISPs lose around 1 in 10 posts with stunning regularity. They lose the same posts. Newsguy fills in around 7 of 10 of the lost ones, and dfn another two. I still think I lose around 1 of 100 postings though. Many of the delayed ones show up through dfn first. -- mrr

I use newsguy so that may be why you can get mine without delays. > > Newsguy fills in around 7 of 10 of the lost ones, and dfn another > two.

It was a product in 1983. No - Lynn's talking about the 5100 from 1975, long before the 5150 (the original IBM PC) was announced. Nothing to do with the PC XT/370. The 5100 was a PALM-based machine that evolved from the SCAMP prototype, and was intended as a small APL machine (though the Wikipedia article says it also ran a BASIC interpreter based on the one for the System/3). Another article about the 5100: http://www.cedmagic.com/history/ibm-pc-5100.html I remember a nice piece about the SCAMP in one of the PC magazines in the '80s (might have been _PC Tech Journal_, based on what I vaguely remember about the article layout), including some quotes from people who played with it. -- Michael Wojcik Micro Focus Rhetoric & Writing, Michigan State University

An interesting box. Portable, for some definitions of portable. As I recall, there was a switch on the front to switch from APL mode to BASIC mode. I mainly used it for BASIC (circa 1979). Gave all my docs to bitsavers.org. scott

They wanted to use blue illiad and got mad when we proposed a gate array alternative. del |
