[comp.sys.cbm] C128D vs. C64/1541 compatibility

kudla@pawl.rpi.edu (Robert J. Kudla) (06/06/90)

Hi all. I've had a C64 basically since it came out, but mine broke a
few years ago. Since then, I've moved away and my brothers bought a
replacement, but I have about 200 disks of stuff they never use and
I'd like to play some of my old games, not to mention use GeoPublish
and stuff. (I have an Amiga 500 that I normally use, just in case any
of you were thinking I'd use an 8-bit as my main platform :) ) Since
the 128 has a 640x200 mode, I think it'd make a nice termulator as
well, so I'm thinking I'll pay the extra $100 difference between the
C64 Test Pilot package and the C128D (I can get one for $399) for the
extra features. (A detachable keyboard is nice too.)

A couple questions though:

(1) Is the 128D as 64 compatible as the 128 is? That's all the
software I have now and I need 64 compatibility.

(2) Is the drive in the 128D (I presume a 1571) able to be compatible
with stuff like C64 speedloaders? A lot of my w3software (including
most of my editors, the BBS I wrote, etc) is in Vorpal format, and
besides that I use the old 7 block fast booters often. It'd be a
bummer if it didn't work.

(3) Will my old 1670 modem work with the 128D? How about cartridges?
(I still like Omega Race, and I have a Final Cartridge
screendump/memory dump cartridge I'i]d like to use.) Also, they imply
hw3e 128D is expandable to 512K, but I know the 1750 et al. aren't made
anymore. Is there any way to do so?

(4) Is there anything at all special I should know about the 128D? Any
advice is welcome.

And on a more general 8-bit note..... Does Quantum Link still exist?
Though slow, it was fun and there was a lot of great software to be
hadzV, especially for the 128 which never had a lot of support. I'd
like to use it again if it exists, so I'd appreciate a current contact
number. Same for American People Link, in fact.

I know a lot of this has probably been covered, but I've been way
behind on news so I haven't seen any of it. If you think it's w3too
specific for the group, please feel free to mail me if you have any
input on this. I'm pretty psyched to be getting back into 8-bits.

Later.

To all your above question, the answer is a resounding yes!
The C128D can emulate 100%ly the C64, and the 1571 can emulate 100%ly
the 1541.

Your are correct...but........           
I just got the latest catalog from TENEX and one of the new items that
they have started to carry is a 100% 1750 REU clone. This product
was already available for number of years, and now it is being
distributed by TENEX.

Yes, it is still there, and it has probably grown since you last
been there, and few more features. One of the feature that made
news was that Q-Link can now play music while you are on line (i think).

Yes, the 128 is expandable to 512K, if you get an REU to do this.  However,
you do not need a 1750 to do so.  The 1750 clones are overpriced ($199.95) 
and you can do the same thing at home if you know how to hold a soldering
iron and how to be careful about being grounded (touching something metal
or standing on a conductive surface).  If interested, let me know or get the
directions off of one of the mail servers.  This basically involves buying a 
1764 REU and adding a few memory chips to its innards.  A more elaborate 
expansion adds up to 2 MEG in 256K increments.
