Ok, there are only two different controllers there. The single density MDS-An {single density} and the MDS-ADn{dual density}. The MDS-AD does both single density and double where the original MDS-A only can do single. The numeric variation stand for minor board variations. If you compare carefully you will see in the MDS-A series that some do not do all the pads for the etched edge connector. They are identical otherwise. >How do they compare?

I see Bt 463, that chip looks bigger than the 21164! Just looking at it makes me want to write an Xserver! Chris Tribo, NetBSD/pmax

Sun keyboard cable? Straight thru?

by claudew＠videotron.ca

Hi Perhaps you have seen my messages on starting up a sparc2. I am a sun newbie.... Should the mini din8 cable to the keyboard be straight thru or have some pins crossed over? I opened up the type5 keyboard I have connected (sparc2 does not ID the keyboard...) and checked the 74LS06 chip where the rx-tx should be coming thru and I feel the chip heating up...abnormaly... Something tells me my cable to the keyboard may have the wrong config...Its not an original SUN one... I found the pinout for the keyboard but what about the connector at the sparc2 end...??? Claude

Who was first with ^Z^X^C^V editing shortcuts

by mmcfadden＠cmh.edu

Aren't there TECO commands that perform these or similar functions. Mike mmcfadden(a)cmh.edu

The Apple Lisa, introduced in January 1983. It wasn't the control key, though. It was the Apple key. But the principle's the same.

Who was first with ^Z^X^C^V editing shortcuts?

by epgroot＠ucdavis.edu

A thought occured to me as I was trying to figure out setting up X-Windows to use certain editing shortcuts: ^Z = Undo ^X = Cut ^C = Copy ^V = Paste ;how the ^H^H^H^H does a v represent insert text from cut buffer? These are ubiquitous now in Windows programs, but who came up with this group of editing shortcuts that cluster so neatly on the bottom left of the keyboard, right by the Ctrl key back in the early micros? My bets are Microsoft stole it from Apple. I don't recall this from WordStar, with its myriad of Ctrl key combinations. One problem with ^C in CP/M and DOS is they would promptly take you to the OS prompt from most programs. Regards, Edwin

Ill probe with a scope if I have to... That's not a frequent failure. I'd suspect a toasty keyboard. Can you get your hands on a different one to try?
