Re: Replacing the 6502 with a faster chip

["brad" <mrbrad@(remove)ll.net>]

ok...maybe scale back the idea a bit from a complete kit with a total //e
bottompanel replacement...maybe something smaller...

my humble ramblings below

(beware..rookie at work...read at own risk...i can barely design an easter
egg...here goes)



is there some way you could take an existing //e backplate...and creatively
stamp out the reguired //gs  back panel...or maybe just have a paper
template a person could stick or decal on his/hers existing //e inside of
the  backpanel showing where to drill holes for motherboard mounting of a
elsewhere purchased/gotten //gs motherboard (ie ebay) and then just have the
kit say to cut off the the entire vertical rear  back plate of the orig //e
backplate off and using said holes you drill into your converted //e
backplat mount the enclosed 3" by what 10" replacement //gs type backplate
with the proper gs holes/etc like the //gs upgrade..on to your own modded
//e bottom plate?.....so to revamp my ramblings

1) you get a transparent (would be best..paper could be used)  or paper
template so..you could move it around a bit and get it just right.on your
//e bottom plate where the motherboard mounts....(maybe not necessary.and
again .paper version prob would do)...and drill the holes out needed for
your soon to gotten //gs motherboard to your //e whatever case..your
upgrading too

2) directions on what bit sizes to use to drill out said template for
motherboard with proper motherboard clips (plastic would work best...if
metal ..i. think the //e backplate metal is soft enough self-tapping ones
would work..or pop in types....i've seen enough pc clones to know a lot of
that stuff exists that would work with a //gs attachment of the motherboard
to these new drilled holes

3) *supply your own hacksaw* and cut off the back panel plate ..so you could
attach the gs version backpanel plate (w/2 or 3 angle brakets or whatever
method attach) to your orig drilled out..and backpanel removed //e
backplate...of course the screw holes to attach it would already have been
drilled out on your modified bottomplate for whatever method of attachment
it uses (prob better methods then i'm tossing off on the fly here)..again
this backplate would be the only metal thing that would need to be designed
and included in the kit....with //gs type openings for keyboard etc etc
essentially looks like the back of a //gs

4) directions on how to use a solder gun to attach the reguired keyboard
plug (at least on rom1 motherboards) for the //e keyboard as well as the
power plug changeover on same said motherboard (or some other creative
????buggie???type adaptor?)..too finish it off

so my ramblings are odd here as i re-read the above..but generally...make it
idiot proof...you get a kit..

...you saw off backplate rear portion with ports off your //e
backplate...you have a template you lay down..with drill bit sizes per hole
you need to drill...you have a //e to //gs inspired type back end with ports
etc that mounts (via your template drill holes etc) attaches anyway to your
nice little //e bottomplate modification...this again is hard item comes
with the kit....you further have all the necessary tricks to mount your gs
motherboard (again not sure maybe rom 1 only?) and add a //e keyboard socket
and or some kinda //e powersupply mod ...add socket ( think there is a place
for this silkscreened on...(or other cable trick from //e power
supply...maybe an adaptor cable to get leads correct to standard gs power
plug ...buggie where are you?...advice???) and viola you toss in a cool
decal of your own ego (whoever is crazy enough to make said kit..options?)
to pop on the front...like the apple //gs insipired one that came with the
orig //e to //gs upgrade kit.


a pain to make the backplate with the //gs cutouts etc...but that is what
would make it cool and worth the efforts...sure it would be a hack but
FUNCTIONALLY it would be exactly the same as a //e to //gs upgrade....but a
cheat/kit...and a bit more cool then a pure hacksaw hackup job...(i have one
of those..yech....i've no talent for metal work..with a dremel grinding
tool)

can't be any harder the my modification of my transwarp gs w/32k board to
14mhz...that is a scary mod..this is pretty much straight forward

anyway....maybe the metal stamping stuff would cost too much...there has got
to be a mech engineering student out there needs a project or a tech college
shop/robotic machining ..who needs a guick dirty project.....(where are all
those model railroad types with metal working experience when you need
them??)

anyway..besides just taking a dremel tool and moding the ports in the back
that way (i know i have one like this) and eyeballing keyboard placement and
drill holes that way (again ..done so) and hack it together that way...(this
is my kinda sorta made to order //e to //gs upgrade kit..) that works
too..but i'd pay $50 for a kit insteadk...easy not to have to..ever ..ever
do it...that way  again ..major pain...in the butt (of course others prob
have wonderful looking ones..i keep mine in a box deep in the basement..it
works but too painful to look at)

ok....again .....just doodling on the idea here...take it as you wish...but
this an't exactly rocket science like making the cffa card is...(as you can
see i've reached the top of any creative efforts ....on my part for the
apple // modifications and stuff..and it so sad ...cause a hacksaw is
involved..which shows my lack of any real knowledge...sigh)

anyway my 2c worth
