This is the most impressive packaging I've ever seen from an eBay seller!

Good Morning, Everyone!

Today's retro pick is the "PET 64" also known as "Educator 64-1" or "CBM 64".

It's basically a Commodore 64 in a PET case.

Rumor has it that the NY state education department demanded a more heavy, solid case for the educational Commodore 64s used in schools as these seemed to "disappear" due to their compact size and light weight. Also, by recycling PET cases, Commodore could present an educational version of the C64 at almost neutral cost.

The Kernal has been modified to display a monochrome, black and white screen as well as displaying all sprites in the color black. This can temporarily be undone by using the following Poke:


Otherwise the mainboard used is an ASSY 326298, Revision A

Later models of this system used a color monitor but production ceased in spring 1983.

The number of Starlink satellites was striking. Lines of them following each other on similar orbits were so regular I could use them as position reference.

I am glad I am seeing the sky while it lasts.

Wet ground from rain yesterday, so a back garden set up:

It's getting really hard to get hold of floppy disks these days, & I'm not talking about 3.5" ones...

An order of used disks off ebay arrived today & some look unused.

Others could be interesting - will need to see if they have anything on them.

I am curious. Does anyone code on an iPad?
If so, what app do you use?

This is the first time I've ever seen a Recordable Laser Disk.

From birdsite where there's an interesting thread that started from my toot yesterday about the BBC Domesday machine I spotted on eBay:

Some #teletext #pixelart #MastoArt of Doctor Strange. Super low res, very limited colour pallete (3 bit)

Understanding the bin, sbin, usr/bin , usr/sbin split in Unix

It originated from the PDP-11 RK05 disk packs being too small in 1971, only 1.5MB each

I love the comment's printed on the card πŸ˜‚

i'm happy to announce the completion of my latest project, the MC Mechanic! it's a POST card to help you troubleshoot your weird old IBM PS/2 computer's Micro Channel bus!

That said, package design hasn't changed much ever.

One lucky sod here in the UK won Β£184m in the EuroMillions lottery last night...

Check out the "Altaid 8800" - a palm sized Altair 8800 clone based on a *real* 8800 processor (no Arduino / Pi etc.) created by Lee A. Hart - Read all about it here:

The dumbest thing about early IBM PC design is the floppy interface. See, at the time, the standard was the Shugart interface, which allowed you to have four drives on one ribbon cable, with each one set to one of the four DS[0-3] settings.

IBM, to save money, pulled some fuckery, setting all drives to DS1, and using a modified cable to discriminate. This limited the PC to two floppies per controller port.

I'm browsing through the Acorn section on eBay & Amazon Assistant keeps suggesting Acorns... as in from Oak trees...

What gets me though is that people buy acorns? I mean pick the right time of year & you can just pick them up off the ground for free πŸ€¦β€β™‚οΈ
