I like old hardware and to start projects I'll never finish.

Oh and it added unwanted effects on the text too. The black border around the "LE BOSS" title are not there on the original document. For added comparison, here's a comparison with the scan and a phone pic.

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...
The software is buggy (doesn't recognize selection half the time), auto-trim and crop is useless, flattening doesn'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.
Here's a picture of the cover page "scanned" 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.
It would be alright for doing quick and dirty scans, but the quality & software doesn't warrant the high price when a phone and ScanTailor have better results... And the phone is less expensive than the scanner. Boo.
In a nutshell, don't bother. I'll go back to my flatbed for the time being and will try to get a Plustek book scanner at a later time.

Some neat info about 70s hard drive contaminants.
From the DEC RK05 disk drive maintenance manual (DEC-00-HRK05-C-D)

Well, I also came across these files in my archives. The original uploader name sounds... familiar :-)

I can make you a zip image yeah. IMD files and the rest are a pain to open. cpmtools is good, but it's also very finicky...
I'm working on adding CP/M filesystem support to the HxC Floppy software, but it nowhere near complete.

I probably have a Multiplan disk image for the Otrona Attaché if needs be.

Sorting through a box of modern-ish (2000s~2010s) integrated circuits, which I'll give away due to never having any use for them.
I'm starting with the tubes, but it's taking a lot of time.
Is anyone interested in what's inventorized so far?
The first table with bags doesn't have proper quantities, it's what was written on the original Mouser label.

Xerox Alto uses 74181, not AM2900. There's the Mick and Brick book for the AM2900 family but it's a brain twister.
As for schematics, check out the ETH Lilith. Everything is available on bitsavers and the schematics include handy block diagrams

ADM-3A terminal first test: this is a triumph.

It's an Open University Hektor III, a little computer companion for a course on computer design!
It came with a lot of documentation and a few software tapes.

The mystery computer is...
A R2E Portal! It was an French Intel 8085-based luggable intended for accounting. It used the Prologue operating system. Didn't sell well and was forgotten by most.
I'm surprised at how good the build quality is.
The wikipedia page for this machine was written by an auction house trying to sell one, and features a bunch of equid-defecation. They tried to pass it as a very influential machine, and the first true luggable. It's absolutely not.
The machine belongs to @npub12s8…f6e5 and we plan on reversing/documenting as much as we can

Recently saved a lot of unused MCX and MMCX hardware from the dumpster: solder connectors, crimp connectors, cables and adapters.
Would anyone have any use for it?

Just to let you know, I made 2 piles for the both of you :)
I won't ship them right away as I'm sorting through the parts and will offer more stuff, then dispatch everything at once

I did find some Zilog parts but they're the kind of parts I use in my tinkering (CP/M era machines). No sound chip so far but I got a few ISD1416P voice recorder chips I won't use.

I might have some more in another box, and I gave a bunch away to friends IRL already.
A seller here has these kind of lots every 2 weeks or so, and they're full of goodies. I'm trying to sort through and dispatch everything I won't use. Got my money worth of parts from it already ^^

PLCC, and I got enough for the both of you. I just need to gather all the chips in one place, they're from 3 separate lots

2024-08-14 21:56:53 GMT

Would anyone have use for a non-reasonable quantity of CPLDs from the Altera MAX7000 family? EPM7128, EPM7064...
I got a lot in a recycling lot, and won't use them.
