Extended Basic Plus - Sebasoft 1987

[kl99]

I got a wonderful wedding gift from Ermanno from Italy - Astharot on atariage. It is an Extended Basic Plus I didn't know existed. It is from Sebasoft from 1987.

There was no single reference to it in the whole The Cyc (cadd99.com).

 

Now after honeymoons I finally had some time to examine it, at least by opening it.

 

 

 

 

 

Is this some unique PCB layout?

It seems it shows ROM and 2 GROM to the TI, but fakes the GROMS to the TI using standard Eproms and some logic.

The board uses TMS27128 for some reason, which means 16k per chip if I am right.

I made lots more pictures of the PCB parts if anyone is interested.

Considering taking a dump of it?
