What do you mean by "pedigree" in these statements? Basic English (which, contra the Wick, is "Business, Arts, Science, Industry, Commerce English") is the failed pipedream of a single person (and I'm speaking here as someone with 40+ years and undergraduate and graduate degrees in linguistics). It's an attempt to round off the corners of a natural language in order to make it easier for those unfortunate enough to be born elsewhere than in the United States of America to be governed by those more graced by God. In what way does that constitute a pedigree? And it's interesting that you chose, of all languages, Old Church Slavonic as your example. OCS was based on the South Slavic languages of the 10th Century (CE) Balkans, with vocabulary borrowed as needed >from Koine ("New Testament") and Byzantine Greek to fill in the needed concepts for expressing (Orthodox) Christian theology in languages which did not share that world view. The Christian scriptures were translated into this refined and enhanced language for the purpose of converting the heathen Slavs from their old ways of belief. It worked. I'd say that that's a pretty damn good pedigree as these things go. Damn, this soapbox didn't look so tall when I climbed up here. Rich Alderson not speaking for anyone but himself, and so including no .sig that might lead some reader to think otherwise.

Sounds like you have the basics covered. Are you running your Z-80 CPU board at 4MHz? Though I'd find it unlikely that *both* controllers would be seriously out of adjustment, I'd also check that the data separator oscillator is at the right frequency. Instructions are in the FDC user manuals for checking and adjusting that.

Cromemco FDC

by dm561＠torfree.net

Date: Tue, 10 Jan 2012 15:00:21 -0800 (PST) From: Fred Cisin <cisin at xenosoft.com> Subject: Re: Cromemco FDC <snip> > Although most 1.2M drives can be configured for 80 track DOUBLE (NOT > "HIGH"!) density, it adds additional unnecessary variables. 1.2M is the > WRONG drive for that FDC port. It might be feasible to cable the 1.2 (or a > 1.4M!) drive to the 8" port, but don't even try until you get the "normal" > stuff working. ------ I hate to argue with you of all people, Fred, but what is your reasoning? Why "DOUBLE (NOT "HIGH")" and why is 1.2M the "WRONG" drive type? IMHO it's the opposite: HIGH (NOT "DOUBLE") and 1.2M HD is the BEST choice with a 16 or 64FDC. >From the controller's point of view a 1.2MB HD drive/disk is indistinguishable from an 8" DD drive/disk, and a number of us are indeed happily using 'normal' 360RPM 5.25" 1.2MB HD drives & diskettes and even 3.5" HD drives (set to rotate at 360RPM); the only mod needed is to switch the pin 34 jumper from the PC standard /Disk Change to /Ready. If by 80track/double density you actually mean 'quad' density, that's not really supported although if the drive also rotated at 300RPM instead of 360 then I suppose you could use 1/2 of it as a 360K DD disk. If you want to go to the trouble of making a 34<>50 pin adapter then you're good to go; on the other hand, the nice thing about the FDCs is that they have both 34 pin and 50 pin headers, so as long as you connect the /ready signal to pin 34 of the 34-pin header you can put all 4 drives on the same 34-pin cable in any mix of 5.25DD, 5.25HD and 3.5HD . As I've mentioned, for whatever reason (RPM, transfer rate, short inter-sector gaps?) most people have far more trouble creating Cromemco-readable 5.25"DD disks from an image on a PC than 5.25"HD (as 8") versions (not to mention 'real' 8" drives); that's certainly been my experience. And of course you do get more than three times the capacity. mike

osborne 1

by tdk.knight＠gmail.com

found a mint looking osborne 1 today local computer recyler they had not even looked at it yet so i managed to get it for decent price got it home opened it up found some cpm disks nice little bonus and a mint looking interior http://img268.imageshack.us/img268/4927/osborn.jpg i tried firing it up and it powers up for fraction of a second when it trys to do its power on beep and dies. http://youtu.be/WXzI-FIr50w << see here what its doing (my ipod tuch sure is usefull) i'm guesing its the power supply but want to make sure befor i tare it apart. i've got another one that does weird things that also needs servicing but one of the face plate screws is striped so unable to get it open to look..

ID: Odd cable?

by cisin＠xenosoft.com

I just tripped over an unusual cable: It has a trapezoidal thin black box labeled "TRS0-80", but no part number, one side has a few inches of cable with a 40 pin card edge connector, the other side has a few feet of cable with a 50 pin edge connector. 40 pin was probably model 1 expansion bus (I hafn'y messed with model 2/12/16). But what did Radio Shack use on model 1 with 50 pin? -- Grumpy Ol' Fred cisin at xenosoft.com

Gartner and friends (was: Windows piss-and-moan-o-rama)

by wdonzelli＠gmail.com

Hmm...questioning statistics with conspiracy...if that does not raise the big red kook flag, I do not know what would. ANYWAY... Market reports and surveys from years past are actually pretty interesting to read. Gartner is probably the best known of the bunch. Is anyone actively saving these reports? I assume CHM is. -- Will
