I couldn't give mine away, even with me paying for shipping, if that's any indication. One of the few items in my collection I have outright discarded. -- Jim Leonard (trixter at oldskool.org) http://www.oldskool.org/ Help our electronic games project: http://www.mobygames.com/ Or check out some trippy MindCandy at http://www.mindcandydvd.com/ A child borne of the home computer wars: http://trixter.wordpress.com/

Floppy drive track-0 issues

by classiccmp＠philpem.me.uk

Hi guys, I've got a Citizen Z1DE-55A (3.5" 1.44MB PC) floppy drive hooked up to the disc analyser (it seems my Sony MPF520 has a duff head; it's reading garbage for one side of the disc). Here's the problem... - When the drive is selected, irrespective of head position, TRK00 is always inactive. - If the drive is given a seek command, it will seek to track 0, assert TRK00, but the INDEX and READ DATA outputs will go idle (float high). - The drive remains stuck in this state until power-cycled. Has anyone seen this kind of thing before? The MPF520 had a head-step lockout (if track0_sensor == active, then ignore STEP commands) but didn't crash out if you asked it to step. For what it's worth, the drive works fine in my PC... I just can't see why it's locking up like this. Also, am I right in thinking that pins 12 (DS1) and 16 (MOTEN) are the two I need to pull low to select the drive, if it's connected before the twist in the cable? And that DS0 and DS2 would be the select and motor enable pins (respectively) if the drive was located after the twist? Citizen are, as always, their usual "helpful" selves: "We don't make floppy drives, we never made floppy drives. LA-LA-LA, NOT LISTENING!"

FIDONET Node List 1986 #164 (June 13 1986)

by billdeg＠degnanco.com

I found an old FIDONET nodelist from June 13 1986 in my files today. This list is missing from any online archives I could locate, but I assume that there *must* be a comprehensive list from the 1980's, right? I have uploaded the nodelist here: http://www.vintagecomputer.net/fidonet/ 1986 #164 Here is the best archive I could find in a brief search of the web: http://ambrosia60.dnsalias.net/fidonet/nodelist.php Does anyone have any nodelists they'd like to share? If so send to me and I will post on my site. It's a shame that there is not more of a comprehensive nodelist archive. Bill

RAM for a VAXstation 4000 VLC

by jbglaw＠lug-owl.de

Hi! I've got my hands on a VAXstation 4000 VLC, unfortunately with no RAM. Though I'm not 100% sure, it seems it would work with fast page 72pin SIMM modules (FPM), as long as it is with parity. Does anybody of you have some spare (up to 6) 4MB FP-SIMM modules (= 24MB total) with parity for me? Thanks, JBG -- Jan-Benedict Glaw jbglaw at lug-owl.de +49-172-7608481 Signature of: Alles wird gut! ...und heute wirds schon ein bi?chen besser. the second :

They are still 68030 based machines, but as far as value they don't have much. I always wanted to use one of the lc3's I have for a linux box, but have not had time to see how that would work out. jim

A friend of mine has one of these. I know nothing about them. Just wondering if this is likely to have some financial value. I know it depends on what buyers are prepared to pay and all that, but just wondering as I could not find any on ebay, so is it unusual or just uninteresting? Thanks Rob

PT210 serial board

by dgriffi＠cs.csubak.edu

Is anyone here interested in connecting a TRS-80 PT-210 printing terminal to something through an rs232 serial port? I just put the finishing touches on a board layout I made by following the schematics in the service manual. The next step is to have a prototype made at batchpcb.com. Anyone interested in taking a look? -- David Griffith dgriffi at cs.csubak.edu A: Because it fouls the order in which people normally read text. Q: Why is top-posting such a bad thing? A: Top-posting. Q: What is the most annoying thing in e-mail?
