GISN-68K SCSI card

[SQZ]

Hi!

I got recently this SCSI card, and as I did not see any info about it, i made a photo and dumped the eproms and GAL. Maybe this info is not important for anyone, but.. Just my 2 cents



(Please, if the attached files are not allowed here, tell me and I'll remove it!)

I hope this would be useful for someone some day...

 Hi SQZ !

Thank you for your contribution. Would it be possible to make a pic of its other side ?

 Hi SQZ !

Thank you very much ! One last request. Would it be possible to make a hi-res pic of the front side, just like you did with the back side ?

Update: Sorry, me bad. Just found it in the archive.

Thanks for the rom dump SQZ !

I've done a bit of analyzis : it's 8KB, and is more or less the same as other known ones. They are all compatible. One minor difference is that it seems allowing SASI hardware to coexist with it ! Most SCSI boards firmware keep the DMAC for themselves...

Hi, I analized the .JED file from your PAL dump and I can say the device is secured since it's like it was empty (fullfilled of '1').
You need some special device in order to reverse protected PLD like the Charles MacDonald dumper (which I own):

There is also a new chinese programmer which claims to by-pass protection on PLD but I never tried it:

What was the original device, maybe a PAL16L8?

 Hi Caius !

According to the first screenshot it is a GAL16V8A

OK, yes, I see it.Anyway the device is locked so dump is useless.
