Bios ( ROM ) de Camputers Lynx [buscando versiones]

Mensajepor Peter Todd » 03 Ene 2014 23:18

I am trying to get as many versions of the Lynx ROMS as possible.

Please if you have a Lynx 48 or 96 or 128 could you upload the ROM image to this thread so I can check it against the ones I have already.


Thank You


Peter

Thanks ron Il check these against what I have - they look like the 4 sets of PALE ones that I have already though.

I have:
2 x 48k
3 x 96k
2 x 128k

sets. I will get checksums for them and post here tomorrow.

Best Regards!
Pete

I suposse my ROM images are the ones you can easily find in the web (most probably downloaded from your page); but, is there a way to dump the real one?. I havent checked it yet; but if the ROM is socketed I can dump it easily, if not, Ill need to save it to tape.

Hi yes I suppose I should have said not from emulators . You could also just check the roms from pale against the ones in your machine.

In fact... Thinking about it. ... I might write a little program to checksum the users rom and then we can just check whether we have their rom already.

I am interested in any roms which are different to those from pale, or any roms which have been produced by third parties. For example I have a Scorpion ROM in one of my 96k machines.

Herere my own ROMs...

Ive found that theyre the same as found in the 96K model. Comparing them with the ones you provided with Pale:

lynx96-1.rom = Lynx48K_IC46.rom
lynx96-2.rom = Lynx48K_IC45.rom (except last byte, $FF instead $00)

ah excellent final confirmation that the final byte in the Pale rom is incorrect - I always thought it looked a bit odd. I will recheck the original
that I received. Thanks very much for uploading the set.

So far I have

48k Rev 1
48k Rev 2.0
96k ROM 3 Rev ? have to check
96k ROM 3 Rev ? have to check
128k ROM Rev ? I suspect 1.0
128k ROM Rev ? 1.0 modded by M Smith

Ill take some checksums and see about a little check program.

Yep, I was thinking about a simple CRC check BASIC program (well, maybe with some assembler help...)


Volver a “Camputers Lynx”
