I'm hoping that you printed this: hp 1727A Storage Oscilloscope (275 MHz) with manual, does not power up but for $10 no complaints. If so email me back if you would like to sell it. I will pay shipping.

computer drawer slides

by chd_1＠nktelco.net

The "drawer slides" on the rack of the PDP-11/40 I am working with are very stiff. Were these originally lubricated? My instincts are to use a little bit of wheel bearing grease, but I was curious, because there was not much residue. -chuck

YAIDU

by dave04a＠dunfield.com

(Yet Another ImageDisk Update) Hi Guys, I've posted version 1.02 of ImageDisk to the site. This was a major code cleanup (it was due), plus a number of enhancements and minor fixes, as well as one MAJOR fix - if enough errors occured to trigger a reanalysis, the sector numbering map for that track could get corrupted.

WTD: CBM Pet 8032 64K memory expansion installation/users guide

by billdeg＠degnanco.com

I am looking for a CBM Pet 8032 64K memory expansion installation/users guide. Anyone have a copy or a URL to a copy? I wish to test an expansion card to verify that indeed the 64K is available, and how to address the memory/test the card. Should there be a different "bytes available" message upon boot with the card properly installed vs. no card? Thanks. Bill

However, if the slides are on the equipment in the racks, ensure that they are properly aligned. A small misalignment on one rail will bind both. CRC

biomation software and lead sets: free

by frustum＠pacbell.net

I forgot to add this to my other posting. I have two floppies in perfect condition in their original holder labelled: GOULD K105 68000/68010 DIASSEMBLER P/N 0117-0397-01 REVISION 50 1989 GOULD K105 68000/68010 DIASSEMBLER P/N 0117-0397-02 REVISION 50 1989 Also I have 14 lead sets for a gould/biomation logic analyzer. Each one has about a dozen wires coming out. No grabbers though. These were bought separately from the floppy above. I bought them a long time ago after seeing a lot of biomation logic analyzers at foothill and livermore without the leads (or pods) so when I saw the lead sets at weirdstuff, I grabbed them. Then as things turned out, I ended up getting an HP logic analyzer instead of a biomation. Free.
