Lately I've been wanting to do RS232 stuff with my laptop instead of desktop machine. Would someone please recommend a good USB-to-RS232 converter? -- David Griffith dgriffi at cs.csubak.edu A: Because it fouls the order in which people normally read text.

HP 7470A plotter -- repairing/replacing paper feed rollers

by classiccmp＠philpem.me.uk

Hi guys, I've just acquired a HP 7470A in a lot with some other gear, and it seems the rubber paper feed rollers have deteriorated somewhat. They've acquired a gummy consistency, and are covered in flat spots... Has anyone managed to find a source of replacement rollers, or a way to repair those installed in the plotter? Thanks, -- Phil. classiccmp at philpem.me.uk http://www.philpem.me.uk/

by ljw-cctech＠ljw.me.uk

I'm having a clear out, so before this goes to the recycling, does anyone want any of it? Free for collection! All in the UK (South Northants / North Oxon, nr Banbury OX17) or could get them to London in the next week, or York/Manchester next month. As far as I know everything worked, but it's been a long time since I used most things so no warranty. If you want to know anything more, just ask and I'll do my best.

DECstation 5000/120 bad power supply...

by bdwheele＠indiana.edu

It looks like the power supply to my decstation 5000/120 is shot. The storage expansion, which is connected to the the switched C13 on the power supply, powered up as expected but nothing on the box itself. There was a bit of a smell, but no magic smoke :) So how hard is it to repair a power supply for this? My soldering skills are mediocre at best. Should I bite the bullet and turn it into this monstrosity: http://web.archive.org/web/20041210172801/http://www.xanthos.se/~joachim/DS… Its really not been my week with my DEC equipment. I almost hesitate to power up my vaxes! Brian

DiscFerret disc analysers for sale!

by classiccmp＠philpem.me.uk

I'm sure most of you are probably aware of my DiscFerret disc analyser project: http://www.discferret.com The Cliff Notes: it's an enhanced, ground-up-re-engineered Catweasel-type disc analyser, with a USB interface, more accurate data sampling, and ST-506 disc support (with an adapter board). All the design files and source code can be downloaded freely from the website above, and are licensed under OSI-Compliant open-source licenses. I'm doing another hardware production run in the next week or so. I have 25 blank PCBs ready to assemble, and parts arriving on Monday to assemble them. For extra bonus points, I managed to get a good deal on the power supplies -- these are now ?5 cheaper while stocks last! Prices are: - Fully assembled and tested unit, no cables or PSU: ?139 - Cable kit -- supports up to two drives, 3.5 or 5.25-inch, PC- or Shugart-style (34 pin edge connector or pin header). Power is supplied >from the DiscFerret. Add ?10 - Power supply - add ?22.50 - Shipping -- fully tracked and insured! UK mainland -- ?7.50 Europe -- ?15 USA -- ?17.50 Unfortunately there's not a lot I can do about the international shipping charges... I'm looking into alternatives... To order -- email me at philpem at philpem.me.uk, and I'll send you an invoice for the total. Payment is via PayPal, or BACS / Faster Payments transfer (the latter for UK customers only). Thanks! -- Phil. classiccmp at philpem.me.uk http://www.philpem.me.uk/
