I have prepared a new blog with wordpress at https://vintagecomputing.info !!!

Thank you.

See http://www.cbmstuff.com/proddetail.php?prod=SCP for more details.

Now you can buy the Supercard Pro and there is already a bunch of implemented features.
The SuperCard Pro software is still a work in progress, it will be updated continuously.
New file formats will be supported soon (e.g. often used floppy disk formats) hopefully.
Stay tuned to hear again from them soon.

Just take a look at Frogger run on a Sega Genesis:

You will notice a slightly less acceptable graphics quality, although it's also good playable.

So SNES still rulez... :-)

For you all without a real Sega Genesis console, try it online at ssega.com.

This site provides you a full access to all known Sega Genesis Games but without the need of installing any emulator. Really nice, isn't it ?

For a comparison, see my other blog entry about SNES Frogger.

You can play SNES Frogger also online, snesbox.com will make it possible...

This calculator was a milestone in terms of programming capabilities, but not a success.
It was soon (1.5 years later, 1979) replaced with a similar calculator model but with a persistent memory - the TI-58C.
There was also a big brother with more memory and a magnetic stripe reader, the TI-59.
Both can be upgraded with special modules, e.g. a mathematics cartridge, or even custom roms for aviation.

Compared to other TI calculators of the same era, battery compartment is different (see the two latches/clips inside), battery pack BP-1A differs from comparable battery packs (e.g. for the TI-57) also.
Don't miss the "cleaning a TI-59" page from Marek Czeszek if you're a collector of these wonderful devices.

Friends of casual games will remember one of the most famous classics: Frogger.

For Super Nintendo (SNES), this game was selled only in the U.S. / Canada.
So how can you play it with an european PAL-based SNES ?
Easy, you need only an adapter, which reports a PAL cartridge to the SNES console, but make it possible to use another NTSC cartridge (see picture).

So one of the latest games for SNES, Frogger will run on a PAL SNES, too.
It's a game without any surprises (except one, see later), but graphics are done good enough even for modern days.


Anything else worth to be mentioned ? Yes, it's unbelievable, but this game does NOT save highscores persistent, every time you start the game after powered off and on, Highscores are resetted. Can be an empty/low battery. A bit disappointing.

This was a mixture between an older SR-51A and the later TI-55, it's inner electronics is more complex than comparable other TI models of the same decade.
My own one is working, but in a less desirable condition, around the power switch, painting is already gone. Also, I had to open it because the display was not fitted correctly (see second picture how to open).


How to open... somewhat tricky, also because the plastic material is a bit brittle.
