Much more reliable machine as well.

The easiest way to go on that, Antonio, is to ditch your Apple IIC and simply get an Apple II CPlus. They are much faster, have the built in memory and 3.5 drives. I have plenty of them around here. I have sent them to Canada, Nova Scotia, and Sweden. Remember, they take 120 for electricity.

Hi!
I have been also without receiving mail from the Apple ][ List from May
20th, but I thought it was common in this list... I suscribed that same
day, and because they say "wherever you go, do what you see" (old Spanish
saying) I waited to see what was happening...
Ok. Now for the questions. I have an original *unmodified* Apple //c, with
the original ROM and motherboard - yes, the ones with the modem port bug
and without 3.5" disk support. And I would like to upgrade it to revision
1, in order to have the Mini-Assembler in ROM and, possibly, being able to
get a 3.5" external disk drive to exchange files with PCs via the Macintosh
Classic I own ;-) . The serial port bug isn't a concern for me, because I
only use it to connect the //c to one of my PCs in order to transfer disk
images (or to use the PC as a terminal for ProDOS! :-) ), and it works
without problem at 19200 bps.
I know the Mini-Assembler upgrade would involve installing the new 32 Kb
ROM/EPROM of the Apple //c revision 1. But my model only has 16 Kb of ROM.
Somewhere I have read that you should cut and solder some solder points in
an original //c motherboard in order to make it work with a 32 Kb ROM. Is
it right? Do you have more information? And, where can I get a 32 Kb ROM
image so I can burn it in a EPROM chip? I think a 27256 should work for
it...
I'm not sure if the ROM upgrade would fix also the 3.5" drive support. Is
the new drive supported by a SmartPort driver located in the new ROM, or do
I need an updated IWM chip? In the case of being the SmartPort driver, what
ProDOS version do I need to download to the Apple //c in order for it to
support SmartPort devices? In 5.25" disks I only have ProDOS 1.1.1, the
version that came with my Apple //c... :-(
By the way, I know Apple provided that upgrade (from revision 0 to revision
1) for free, but that was almost 20 years ago, so I think I'm not going to
ask for it in an Apple dealer ;-) .
One last question: do you know where can I get blank or used 5.25" DD
disks? I've run out of them, and have found that HD ones doesn't work, at
in my //e Enhanced's Disk ][ drive.
