I would bulk-convert the tif images to .png, so you get some lossless compression going on. RGB888 tiffs here compress from ~300MB to ~60MB when converted to png, with no quality loss at all.

EDIT: *BUT* if you have bilevel source images (1bpp black/white) such as book scans, schematics, etc, keeping them as .tif with ccitt group4 compression turned on will beat even png in terms of compression. Think '800dpi full page image stored in ~100KB'. This obviously doesn't work for greyscale or color images of any sort, the best that can be done for those is greyscale or color pngs. Documents which used a 2 or 3 ink process (like some DEC manuals and Roland Schematics which have black ink and orange ink), you use 32 or 64 color palletized PNGs.

The new X1 dumps:

I hope it's ok to post them here, they should be old and obscure enough to not raise any alarms.

I've included a few high resolution photos of each cassette, just in case someone is interested.

Yeah, I thought about converting the TIFFs as well, but I uploaded the whole bunch to another site that recently started preserving KF flux dumps as well and they wanted TIFF files anyway (so no worries, they are already preserved, should a bomb explode here or something). Each individual floppy (raw dump + TIFF scan) compresses down to around 30 +/- 10 mb and since I have the space I thought "what the heck" and just left them as TIFF smile

They're unedited anyway so when converting them I would also have cropped and rotated them properly and that alone would have taken days ^^

Oh I forgot to mention if someone wants any (original) floppies dumped we could work something out. Also if anyone has boxes of old floppies lying around, before you throw them away send them to me, I'll happily cover any shipping expenses. Same goes for old CDs, no matter what's on them. Only originals though.

More Sharp X1 stuff. There's still an incredible amount of undumped stuff for these computers...

http://www.r-09.net/stuff/Dumps/Sharp X1/pinball.zip

Fantasian seems to work only on the X1 Turbo drivers, which is weird since the game is supposed to be compatible with the regular X1. I've redumped the cassette a few times, so I'm pretty sure it's some kind of emulation quirk.

Thanks a lot. smile

Just a question, exist a way to convert .wav to .tap for X1?
A tool called "tap2wav" exist.
I think the reverse way is much more complex or impossible.

There's PWMCNV, but it's very old (the EXE only runs under DOS, but the source is included) and very fussy. I've never been able to get it to work consistently.

C64 KoalaPainter cartridge



I figured the picture of the dumping equipment was more interesting than the actual software contained inside that black blob smile

Constructed a c64 expansion port to 27128 adapter, and had to use an LPT Willem since the ZIF socket in the GQ-4X is just plain crap.

I found some technical documents, installer disks and an HDD image from the original BeOS on the BeBox (the "hobbit" prototype). Uploaded it here, in case it's not already well-known and old info: *click*

We might have it, there's some Hobbit stuff floating around. I'll check.

It's appreciated anyways smile

I've finally got round to redumping the Amstrad PC2386 BIOS ROMs with a programmer (the previous ones were DEBUG dumps).

They're at https://www.sendspace.com/file/2v819h

As far as I can see, the bottom 16k of each ROM contains the data for the C000 segment, and the top 16k has the data for the F000 segment.
