Kaypro 10 HDD formatting

by brain＠jbrain.com

More good news. List member Jon (not sure of last name) sent me a known good ST251 to use on the K10. Installed, it spins up, and hdskfmt seems to claim the entire drive is good (which I know it is, but I wanted the app to know it as well). But, the !readme on the disk says that app formats the disk. It does not appear to do so, and thus I need to know how to format the drive (at least as a ST225, I know I can't do more than that without newer ROMs...) Does anyone have some guidance? I see references online to format06.com, but it's unclear if that's what I need. Jim -- Jim Brain brain at jbrain.com www.jbrain.com

Tech Time Warp of the Week: IBM STRETCH, 1961

by lproven＠gmail.com

1981 mini-documentary about a /then/ 20Y old machine. The doc is historical in its own right, it now being longer since the doc was made than the subject of the doc was from the film. Sadly scant on technical detail, though. http://www.wired.com/wiredenterprise/2013/06/ibm-stretch-nsa/ -- Liam Proven ? Profile: http://lproven.livejournal.com/profile Email: lproven at cix.co.uk ?

OT: parking meters

by dgriffi＠cs.csubak.edu

On a lark, I bought an old mechanical parking meter with the intention of putting it in my den. Does anyone else here have at least a passing fascination with these things? I'm trying to figure out where I can get a base and post for it. -- David Griffith dgriffi at cs.csubak.edu

Is it just envy because Tony is such a generous and prolific contributor of generally useful information while your posts despite their much greater number and size usually contribute mostly noise, that makes you jump into a discussion about power supplies just to 'pick on him' like this? For once I have to agree with Tothwolf and his "You, sir, are a bona fide troll," and an often rude and silly one at that; my apologies to the list for adding to the OT. m

SBC6120 Serial Params

by wheagy＠gmail.com

Hi, Anyone running an SBC6120 connected to a PC serial port? A couple questions: 1) Are you using a null modem cable - I've seen conflicting info 2) What baud rate are you using and what are the other serial parameters (8,N,1)? POST looks ok, but I only get garbled text on TeraTerm with every configuration I've tried. Thanks, Win

Gr8bit – a multi-card modular MSX2 compatible hobbyist computer

by lproven＠gmail.com

I'd not heard of this before. http://www.gr8bit.ru/what_is_gr8bit.html The website is a little messy but the machine does seem to be comprehensively documented. I'd be more interested if it was Spectrum-compatible, myself. ;-) -- Liam Proven ? Profile: http://lproven.livejournal.com/profile Email: lproven at cix.co.uk ?

Setting the Scrolling Region on VT100's VT220's VT320's VT420's, VT510's etc.

by cctech＠beyondthepale.ie

Groenenberg and John Wilson, and > specifically in respect of screens of more than 24 lines of which you are the only > one to note what DEC did when more than 24 lines are available. > For another data point, I dug out my VT510 and set it to 48 lines per page. The results were the same. The scrolling region was not altered if the second parameter was larger than 48. In light of what John said in another posting, I also tried defaulting the second parameter and setting it to zero. In both cases, the scrolling region was set to start at the line specified by the first parameter and end at the bottom of the screen. This also worked for me on a DECterm. Finally, I tried a Qume QVT202 (80x24 only) which behaved the same. Regards, Peter Coghlan.

However, I've checked on the DECterm in front of me and <ESC>[016;000r works as expected. Regards, Peter Coghlan.
