RapiDos was a parellel drive enhancement. I only got one drive board, and
I would like to know if the boards still exist, and if the version ever went
up. I bought it from Chip Level Designs.
It says the Computer boards were made in USA, but the parallel drive board
was designed in Germany by mts Data ?
It requires you take out the drive kernal, since it has its kernal on the drive
It has 8 kB of SRAM on board in drive, for full track buffering
It had options that allowed you to format and use all 40 tracks.
The drive board plugged in to where the 6502 went, and the 6502 plugs in to
A read of the error channel upon boot give: 00,PROFESSIONAL 41L2, 00, 00
The screen says I am running RapiDos 2.0
Now, can anyone tell me whether the system is really just PROFESSIONAL DOS
in American clothing?
If it is, or if someone can identify it, do they make it still? Did a new
version come out? Do they have speedups for other drives?
On another note, leafing through magazines last night yielded an ad for
StarDos. Anyone have a copy or know anything about it?
Also, I noticed people keep saying things about Demon Dos and others. Can
people fill in any info on that item?
I know of the following:
Fastload Got two
Mach 5 Family owns one
Warp Speed ???
Turbo Disk from Compute!
Can anyone fill in more or flesh these out?

I think that there was alot a hardware thing called dolphin-dos which
used a parallel cable to load 202 block files in 5-6 seconds. Which is
about the same speed as the Action Replay cartridge loads it special format

Get your copy of the cbm-emulation-faq from: ftp.warwick.ac.uk:/tmp/c64
OR view the c64 web site: file://ftp.warwick.ac.uk/tmp/html.64/c64.html
Hmmm according to my manual these are the difference:
Toggle sratch protection bit. L for RapidDos D for Pro
Pro had the command '@-' which is the same as load"x",8,3
Load"x",8,0,xxxx and load"x",8,0,xxxx,yyyy
Where x is the start address and yyy is the end address was only
available in the PRO
The fast format was faster on the pro.
Motor-on disk seating when disk is instered was not available for the
The PRO could access tracks after track 35 (I don't think the regular
Rapidos has able to do this)
I'm pretty sure the only real difference between the two was the fact
that the Pro cost more and had the extra 8K. I think it also came with
a copy program that would only work with it.
Dolphin Dos was pretty much the same set up.
And if your looking for carts, don;t forget Action Replay, Final Cart,
and Super Snapshot.
One of the greatest thing about RapidDos was that I could use its
monitor to view the code in the Super snapshot.
Rapidos was great, I'ld probably still use mine, but somewhere it got
I don't think Lawrence(Chip Level Designs) is doing anything with
C64's anymore. Last I heard they were selling stuff for the SNES.
I have a Warpspeed cart. It was created by the Alien Technology Group and
distributed by Cinemaware. It works on the 128 and 64 (there is a little
switch) and it supports the 1541/71/81. It has a wedge similar to
Fastload and a Menu of several utilities. I believe version 2.0 was the
last one before it was discontinued. It is copyright 1988/89. Let me
know if you need more info.

ProfessionalDOS is the American original!! I have DiskDemon, which is the
English version by Datel (Don't know if it needed any modification to run on a
PAL machine). I get the same response from the drive upon a reset, but I guess
the ROM in the computer is the only thing modded. I never heard of this one
before, but I guess you have nothing different than the one I have. Do list
your F-kays and I'll tell you more specifically!

Are these pure software based ones or are they placed in different versions of
the ROM? I guess DemonDOS is the DiskDemon. There will be no possibility to
list the software ones. You have things like Vorpal from Epyx. One of the
turbos messing with the diskstorage and not only to pass the data fast to the
computer. It is also known as Warp when ripped and place in the ActionReplay.

I have a device that plugs into the cart port called Jetload. I believe it is
a rip-off of fastload. The DOS wedge is identical and works the same way, same
speed etc. It consists of a curcuit board (NO CASE) an EPROM and a reset
switch on the back that would reboot if you bumped it into anything. It was a
great deal for $12.50 (in 1985 or 6) cause it cut load time by 25-75%.
I have a 1541 with RapiDos that comes up saying PROFESSIOANL 41L2,00,00
in the drive status on powerup. It aslo have this mts Data whatver stuff
on the circuit board I put in the drive. I was told, via the user manual that
the drive unit was from Germany, but the 64 part was from America or UK
(can't remember). here is what I know.
The rive board has copyrights of 86 and 87, which coincides with what the
last poster said.
The unit has a flat ribbon cable that comes out of the drive and plugs
into the USER PORT, not the exp port.
The board on the user port and the board that replaces the kernal ROM are
copyright CLD (Chip Level Designs).

There were two fastloaders. Rapidos and Rapidos Professional.
Basically the difference between the two (I think) is the professional

I have Profeesional DOS Level 2, which is the second cut. I upgraded once
from Level 1, and the only thing that changed is the drive stuff, so initially:

Evidently CLD took the drive board= and made a user port hookup into
the computer for it. Mine has the parallel port interface and code for it in
the ROM, and mine has provisions for two drives to be hooked up.

I tried 2dh:jim to change my disk name to jim, and I did 2de to extend the
disk to 40 tracks. A validate on this unit is SOoooo fast.
So, I do have it, but I would like a second drive board.

The original ProfessionalDOS Kernal allows this, cause the RS232
routines are untouched.

ProfessionalDOS was availible for 1541, 1541C, 1570, 1571 and 1581 on
C64, C128, C128D and SX64.

Professional DOS is not 'the fastest toolkit and drive-speeder system
in the world'. Do you know Rossm"oller's Turbo Trans (TT)? At least
this system is faster, it uses 512KB DRAM+8KB SRAM drive cache, 2MHz
in the floppy and a parallel cable as well. And it is possible to
combine it with Turbo Process (TP) the 4MHz cardridge for the C64.
Of course it's a typical Rossm"oller product which blows up the power
Professional DOS is not 'decoding the original GCR-code by hardware'.
It uses some big tables in the firmware ($7000-$7C00) to decode the
GCR nybbles very fast, but it is still the old fashioned way. Even
DOS2.6 uses tables in the firmware to decode GCR (routine $F7E6-$F8A0
and table $F8A0-$F8E0), P.DOS uses bigger ones - but no reason to call
it 'by hardware'.
E.g. in a 1540 floppy drive a sync is detected by a 74LS133 - this can
you call 'by hardware'. Or the 1581 decodes MFM by hardware.
Reading some tables with the processor is not 'by hardware'!
AB>> Why they changed the name?!?
>Beats me! They also did some SERIOUS mods, like new F-keys (WOW :)!
Which new F-keys?
Mine is using SpeedDOS compatible F1/F3/F5/F7 (LIST/RUN/LOAD/DIR) keys
and on F2/F4/F6/F8 SYS$C000/TOGGLE/SAVE/CHANNEL.
So what they changed?
AB>> I have a very good disk monitor called DiskDemon as well ;-)
>Yuck! Ever heard of DiskMaintenance??? Now THAT'S a diskmonitor, worthy of
OK, that is a word. Mail me the DiskMaintenance or tell me a FTP site
where it is availible and I proove this.
