I have a C128. I run both native and CPM+ mode frequently.

For $20 I received a 2"-thick manual and two more disks. The system is
complete and well documented. Do you have this manual?

Yes, I'll admit the screen is slow, but agonizingly? I wish there were
a way to speed it up. Maybe the Z80A can be substituted by a faster Z80?
As for the letter quality, I don't find the 8x8 dot
matrix all that bad. Try adjusting the color or intensity.
> Forget programming on it. Forget doing any sort of hardware interfacing.
Excuse me, I've had no problems programming a CPM system with complete
BIOS-- I run VDE and MAC just like anybody else. SID is available with
lots of doc. Higher languages are available from SIMTEL20 or RPICICGE.
> Support from Commodore?...Heh, heh, tell me another one...
No problems here either. I get help from comp.sys.cbm (mostly Frank
Prindle). Commodore has helped me when I've needed it...

Actually the speed is closer to 5 to 6 times that. If you really want
a fast system, the 512k RAM expansion is about $160. Use it as the
system drive M: and SETDEF M:,*. The 1581 3.5" drive is available for a
little more, and is of course faster than a 1571.
> It used to break frequently. Try finding a warranty center locally.
I have had a C64 since Jan '84 and a C128 since Oct '86. ONCE I had
to have my 1541 repaired. I had no trouble finding help in Milwaukee.
Mayfair Computers even does warranty repairs!
> Parts availability? Forget it.
Try writing to comp.sys.cbm, will ya? I've read articles advertizing
for video expansion RAMs, C128 and 1571 bugfix ROMs. In any issue of
Commodore's or Compute!'s magazines for C128/64s, there are more ads
for hardware.

Every once in a while I hear someone take a personal vendetta against
Commodore, ragging about everything they do. At least TRY to be objective.
These people hang out in dealer stores and ravage about everything Commodore
does. I swear some of these people must secretly work for Atari...:-)
> My recommendations for CPM machines are as follows:

I would have missed out on C128 native mode and C64-mode (for games ;-))
if I did that. That's a lot of software.
> Hope this helps. If I can be of further help Email me.
Thanx a lot!
