MICE!

2009-11-12T22:54:30Z

I bumped into a couple of more mice in the closet today in my
excursions throughout the house seeking Holiday Ornaments! One is an
Amiga and the other is a 1351.
The 1351 I believe needs a chip, but other than that is in MINT
PHYSICAL SHAPE. the Amiga I have no way to test so I'm "assuming" that
it works ok, but (NO GUARANTEES).

Well Commodore put almost everything into every style case, and
keyboard color, Just because it is the new style
case does not mean it is the 64C h-mos style, there are sightings of
old boards in new style cases, and what not,
when the serial numbers hit 130000X? then the new style small board
appeared, and there are two different layouts of

Is there any way detecting it automatically at all?

I think my IndusGT has JD official roms, lemme look, its burried
though!
and I do have a old 4 slot dos programmer that I can read them from,
seems it didnt have a switch, and there are three eproms if I remember
correctly. It was an older version too, I dont think 6.01 was avail
for the GT
drive, I think it was 5.01 I will let you know.

I'm going to have to correct myself here. There was an official
Swedish JiffyDOS ROM. However, IIRC, the editor ROM ($c000-$cfff) was
unmodified from the C= ROM.
Sure, if I can find them...

Not a case of detecting the sound chip, though Beach Head II had a courteous
option of allowing filter adjustment. Not sure how it worked in practice.
At the time, I wondered why more games didn't have a similar option to
minimise the variable filter levels.

Can I get the patches to verify?
If so, anyone interested in testing?

Well you still hear the digisound but it's far too quiet compared to the
rest of the sound. Just compare IM1 and Ghostbasters on both computers.
Newer Demos maybe were able to detect the correct sound chip but I don't
know of any game that asks you which SID to use.

Not trying to take business away from Ramswell, but arcadecomponents.com
also has RAM chips as well as other IC's for many different computer systems
at a very reasonable price. If you get stuck, try them,

No, they were made by me, and sent as patches to Maurice. At one point
I had a bug in the keyboard map, so if you plan on offering them they
need to be verified. PETSCII $A4, $FA, and a few other are impossible
to type with the official Swedish kernal, but I mucked something up
when I tried to fix this.

Definitely am, I'll pay postage to the UK obviously. Will unscrew the
machine and take a look.

As many of you are probably aware, I acquired a license to sell JiffyDOS
earlier this year and am now ramping up sales.
To that end, I am trying to reconstruct the exact product offerings that
CMD offered. This means verifying images, and determining what original
ROM images CMD supplied with each overlay.

I admit I've never actually played any of those games. However, I
played Impossible Mission I and Ghostbusters all the time and they
were fine. I also remember a handful of other games, programs, and
demos that used digitized sounds and had no problems with any of those
either.
