Well, I've been reading all of the remarks on upgrading an A1000 to 1.4, and
have this tidbit to offer y'all... (sorta commercial?)

About a year ago, (yes, before CMI went out of business) an upgrade was made
to the Processor Accelerator for the 1000 to allow it to hold a 1.3 ROM.  We
did this so that A1000 users would not have to buy an Accelerator, then turn
around and purchase a KickStart Eliminator (I imagine that the real truth to
this is that we were tired of all of the 27256 EPROMS laying around that
needed to be reprogrammed every time a new version of KS came out..)  Anyway,
it turns out that this upgrade also allows a 512K ROM to be used with this
board (actually, I must admit that it was Bob (Kodiak) Burns that turned my
ear to this, so he deserves the pat on the back).  We checked our schematics
and sure enough, it _is_ wired to handle the extra address lines.  So, any
of you PA1000 users that have the KS socket can place a 1.4(+) ROM into it
and it will work.  Now, remember that you do not have a 1M Agnus, nor the
Super Denise, so you won't be able to use any of the "productivity modes"
(but _I_ never use that much CHIP RAM, and ain't got no fancy multisynky
thingy anyway (besides, 4 colors at 31kHz does not turn me on)) - BUT it
_IS_ a start.  This is not a "rejuvenator", but it will allow you to cross
the hurdle of getting your A1000 to run 1.4.

For those who do not have one:

A Processor Accelerator is a 14MHz 68000 replacement that includes a battery
backed clock/calendar, a KickStart socket, an MC6888x math ship socket and
speeds things up (your mileage varies depending on how CPU intensive an
application is).  Incidently, you can run the ROM at 14MHz also, so
Intuition calls (and _ALL_ ROM routines) are accessed faster.

"So, if this is what I want, how do I get it?" you ask.

Well, that's fairly easy... a company called digiFeX bought out all of CMI's
inventory, and the rights to manufacture some of their products, including
the Processor Accelerator series.  Simply contact them, and they'll be
happy to innundate you with the information that you need to purchase one.

Their number is:	digiFeX - (503) 656-8818
and they will be at AmiExpo in Washington, DC.

They'll have to come up with something _way_ better before I'll give up my
garage space for my keyboard....
