The Dell box in the foreground really offends my sensibilities, though. I wonder what it would take for me (someone with NO spending money right now) to get that machine... -Dave -- Dave McGuire St. Petersburg, FL

IIRC Microsoft had the SysV standard 13 character file names in Xenix like SysIII (and IIRC v7). It was BSD which did symbolic links and IIRC 255 character file names in the 4.2 BSD Fast File System... SysV got this in SVR4 (about 1989 or so)... Research had this in Edition 10... Bill

The only difference is the ROMs. Hmm...I think I have a KA650-AA; if the difference is just the ROMs I'd be happy to burn a set for you, Heinz... -Dave -- Dave McGuire St. Petersburg, FL

microvax 3 info: ka650-ba is single user?

by h.wolter＠sympatico.ca

Looking to upgrade one of my Mv2's and came across an auction item with a ka650-ba with 2 16 meg mem cards. The price is right - but it goes on to explain that the -ba is a single user cpu - which seems silly to me. Is there some special thing about this cpu that will only let it run single license VMs or Ultrix? I can't see how they limit that. Is the this bullsh*t? I can't find any google refs that will support the single user claim.. regards, Heinz

ISTR that they were a PLATO site, but I've no idea whether this system was running it or not. Yes, it should run, given the proper peripheral equipment (again ISTR PLATO had unique site hardware requirements). Bear in mind that PLATO is a commercial product still marketed as NovaNET (I believe it's getting yet another name at this moment), so you'd be hard pressed to get legal permission to run it. I suppose you've seen my gallery of PLATO (NovaNET) screen shots; I need to get them moved to the site Jay West said he'd make available so I can add the second gallery. -dq

I'm not gonna get in a snow-marking match on hours spent under the hood... however you are correct in that it's not a very orthogonal processor, and non-orthanogoanl machines are indeed full of "gotcha"s. Having started with orthogonal machines like the CDC-6600 and IBM 370/158, I found even the 8-bit 8080 a pain to work with, and wrote macros to do all the really important work. I carried that forward to my 8086/8 days, and thus didn't have much in the way of difficulty. I had arithmetic macros for 8, 16, and 32-bit operations, and macros to do conversions between them. I worked briefly with the 6800, and more recently, the 6802, and they are certainly a bit more orthogonal, but still too primitive for my tastes. A Coco running OS/9 might be in my future but I wouldn't spend anything for one, it'd have to be free. As to the distinction, I bow to Allison's better wording. Regards, -dq

> While it is true the 8086/8088 is really only a 8 bit cpu, No, the 8086 is a 16-bit cpu with a 16-bit data path; the 8088 otoh is a 16-bit CPU with an 8-bit datapath (or a 16-bit multiplexed data path, if you prefer). Regards, -dq

I'd rephrase the latter as: The 8088 has the same 16-bit core CPU as 8086 with an 8-bit wide _external_ datapath. Whats important about the 8088 is it was the first(or one of the first) to seperate the CPU core (control, alu and registers) from the bus interface. Then again you have Z280, an 8bit cpu with an 16bit wide external data path. Hows that for a switch? Allison

FORTH for TRS Model 100

by zmerch＠30below.com

Rumor has it that Paul R. Santa-Maria may have mentioned these words: >I have AMPI (Amerifcan Micro Products, Inc.) FORTH with plastic case, >manual, and cassette tape (condition unknown) for the TRS Model 100. >Can anyone use this? > >Paul R. Santa-Maria >Monroe, Michigan USA Do you have any way of making a copy of this - for archival purposes? Rick Hanson of Club 100 might be intersted in archiving this for history's sake - he's been in the business of selling/supporting/refurbishing Model 100/102/200's since 1983. He can be contacted at rick(a)the-dock.com, and his website is: http://www.the-dock.com/club100.html -- and coming soon: http://www.club100.org/ Thanks! Roger "Merch" Merchberger

I ran SCO Xenix 286 on a few 286 systems back in 1988 or so. It was abyssmal. I don't remember much about it...I think I blocked it out. :) -Dave -- Dave McGuire St. Petersburg, FL
