The black border around the &#34;LE BOSS&#34; title are not there on the original document. For added comparison, here&#39;s a comparison with the scan and a phone pic.<br/> <img src="https://assets.oldbytes.space/assets.oldbytes.space/media_attachments/files/116/834/170/753/479/269/original/09b5aa6ccbdc5766.png"> <br/> 2026-06-29T15:48:13Z https://yabu.me/nevent1qqsdpsltsj0gvkp8m36ph9frc8wsmdcm70vul3gct6rg9s0r85cm4hgzyzs58uvm5fph884fhtxx47rqrexs6s4ud03hye8fa5cj8cap7mdmvzsrkp6 I bought a CZUR ET Max scanner, assuming it would be nice for the big pile of old computer brochures I have to scan. Never have I been so disappointed...<br/><br/>The software is buggy (doesn&#39;t recognize selection half the time), auto-trim and crop is useless, flattening doesn&#39;t really work and the quality is piss poor. Yet I was testing on what seemed like an easy candidate: almost flat A4 commercial booklet, in good diffused natural lighting.<br/><br/>Here&#39;s a picture of the cover page &#34;scanned&#34; at 600 DPI, and side-by-side details comparison from the scanner and a phone picture. The auto-descreening messed up most of the details, the front page text is oddly sharpened while all the computer details are blurry.<br/><br/>It would be alright for doing quick and dirty scans, but the quality &amp; software doesn&#39;t warrant the high price when a phone and ScanTailor have better results... And the phone is less expensive than the scanner. Boo.<br/><br/>In a nutshell, don&#39;t bother. I&#39;ll go back to my flatbed for the time being and will try to get a Plustek book scanner at a later time.<br/><br/>#vintagecomputing #books #scanning<br/> <img src="https://assets.oldbytes.space/assets.oldbytes.space/media_attachments/files/116/834/126/621/990/385/original/05a549209fc5b313.png"> <br/> <img src="https://assets.oldbytes.space/assets.oldbytes.space/media_attachments/files/116/834/130/622/088/408/original/0580da35b74d75c2.png"> <br/> 2026-06-29T15:39:45Z https://yabu.me/nevent1qqsfdxwthqhg2uwx4tpsvhxwevvvxhv2e2vk6s3degylnwrfs7c9l8gzyzs58uvm5fph884fhtxx47rqrexs6s4ud03hye8fa5cj8cap7mdmvnjtur0 Some neat info about 70s hard drive contaminants.<br/><br/>From the DEC RK05 disk drive maintenance manual (DEC-00-HRK05-C-D)<br/><br/>#retrocomputing #dec<br/> <img src="https://assets.oldbytes.space/assets.oldbytes.space/media_attachments/files/115/437/564/265/341/408/original/bad4c3c6e7767094.png"> <br/> 2025-10-26T00:15:16Z https://yabu.me/nevent1qqspffg6xyuymyyawx4chpw4xty9ze8u7skxvwsvk968526hxef4jtgzyzs58uvm5fph884fhtxx47rqrexs6s4ud03hye8fa5cj8cap7mdmvjax2cs In reply to <a href='/nevent1qqsg2zw5jpjnvp8zphcrgmqmdnk20xxr0ga9efxnakz4jyk5lchmvdsjpj24g'>nevent1q…j24g</a><br/>_________________________<br/><br/>Well, I also came across these files in my archives.
