Well, back about 25 years ago or so, when I was into robotics and things like that, a colleague was telling his wife that "once we get the skin absorbtiveness squared away so we don't end up with lipstick on our drawers, we're going to phase you biological units out completely . . ."

Effective Speed of 10BaseT

by edick＠idcomm.com

SAMBA is that NETBEUI-compatible protocol used by Windows for Workgroups, isn't it? I've heard a lot of mention of it but no details except that its DOS client is HUGE by comparison with the already large but purportedly MUCH smaller NOVELL IPX+NETX. (about 96K). I'm interested in this because I use a set of DOS engineering tools, since they suit me better and work faster than the Windows version, and are less buggy. I'd LOVE to use DOS 6.2x as opposed to Windows since it tolerates my video drivers. I would have to load the same DOS driver/shell under WIN9x in DOS mode, so the same restrictions apply. Yes, multiple versions of what should be the same driver set is what I remember about the ethernet hookups with various versions of DEC hardware. We didn't get around to the MAC's for a while because nobody believed we could make that work. Finally one guy threw up his hands and hooked it up with hardware he carried in from home. That made for some red faces among the senior types! Dick -----Original Message----- From: Zane H.

Need a RS232 interface transputer tram

by rmeenaks＠olf.com

Hi, I need a RS232 transputer tram for a project I am planning on doing. I really dont want to access the PCs serial port due to speed considerations, etc. So does anyone have such a beast for sale?? I dont know what inmos part number it is, but transtech had one called TTM21 and Sundance had one called STM220. Thanks Ram

Samba

by edick＠idcomm.com

That's what I was led to believe also, but it's not true. Even though the ODI driver set is quite a bit bigger than the earlier IPX.com, for every card I've tried out, my threshhold is the required transient area (useable low memory) under DOS 3.22 or 6.22, with all my SCSI drivers, etc, (I can leave out the CDROM stuff) loaded, so I can still use my DOS-based OrCAD for schematic capture, digital simulation, and PCB routing. The PCB router is the crux, since it won't do everything if there's not 600+ KB of available low memory. Not even all the ODI drivers will leave enough space for that. A few of the cards I use will do it though.

I tried a Win '95 installation on my 4MB RAM/120 MB HD/386 P70, and from "power on" to "ready to use" took over two minutes. Trying to open any windows or run any applications caused a frenzy of drive activity (reading and writing to the swapfile, I suspect). I can't imagine anyone actually using a P70 running Win '95. Running Windows 3.11 though, they were decent portables for their time - nice crisp display, good keyboard. Very capable "get some work done in your hotel room" computers. I know several people who have added MCA SCSI cards to the internal expansion slot, and use their P70s as portable SCSI device testers. Cheers, Mark.

Dont want to start a flame war here but

by edick＠idcomm.com

This is actually quite realistic! I was once given an IBM690 with tons of equipment associated with it, the most interesting feature of which was that in addition to doing a little computing on compilers of the generation on which I did my first work, it would keep my horses (since the barn was the place where I had the 3-phase power) nice and warm all winter. More recently I had an opportunity to snag a complete 9370 setup with nearly a TB of (IPI ... yechhh!) disk farm. I would have preferred they blow it along with the rest of the building, though.

One more thing . . . about those wives . . . I've done pretty well without 'em and prefer it that way, having tried it both ways. The old computer hardware's cheaper, easier to live with, and more forgiving. Dick -----Original Message----- From: Ram Meenakshisundaram <rmeenaks(a)olf.com> To: Discussion re-collecting of classic computers <classiccmp(a)u.washington.edu> Date: Monday, November 15, 1999 2:18 PM Subject: Dont want to start a flame war here but Hi, Just curious. What motivates someone to collect old minis and mainframes??? I can see it being nice to look at for a while, but something as big as a mini is very cumbersome to have around the house (let alone an apartment). And what pratical use does it serve running it at home anyway??? I see a lot of posts about collectors having paper tapes, reels, card readers, etc, but how often does one really use it or even turn it on. I would imagine that it probably sets idle for about 95-99% of the time and most people would turn on a PC instead. I have a SUN IPX and a PC. I rarely turn the SUN on, but I keep it around to do some practical UNIX programming on a real UNIX box instead of linux, freebsd, etc. As I said, I dont want to start a flame war or anything, just curious thats all...... Ram PS: If I started to collect stuff like that, my wife will throw me out of the house. She already complains about my transputer equipment... -- ,,,, /'^'\ ( o o ) -oOOO--(_)--OOOo------------------------------------- | Ram Meenakshisundaram | Senior Software Engineer | OpenLink Financial Inc | .oooO Phone: (516) 227-6600 x267 | ( ) Oooo.
