Success Story - September 15th, 2010:

"This thing ROCKS!"

I am located in Toronto, Ontario (Canada) and was a long time member of TPUG.  I bought my Rear Admiral system several weeks ago from mytec electronics.  They sent it to me very quickly and I had it completely installed to my c64 within 20 minutes of opening the box.

This is an extended version, for lack of a better phrase, of the legendary Xetec Lt. Kernal hard drive system.  It has a very nicely updated dos and new menus in lots of places. It's much easier to use because of the many improvements.  The really cool thing is the host adapter.  It is one "sexy" looking device.  It even has a reset button on the back for 64 users, NICE!  The old ICQUB button is now called SMART and it is a blue button on the top with a little blue LED next to it.  It lights up when the button is pressed and even stays on, briefly, during program captures.  It still saves programs to familiar .ICQ files in the same way the Lt. Kernal did, and they work the same. But it's way easier to use and better explained in the menus.  I have already made a lot of archives of my favourite programs and they all load in the blink of an eye.

The fastcopy menu is really easy now, since the "f-key" functions are spaced for one-finger quick operation, not like the "shifted f-keys" that were all jammed together at the top of the old fastcopy menu.  Same thing with the config menus, all of the defaults are easy to see and some really cool popup help too!  Setting up logical units is a breeze since the prompts let you know what you are doing and it doesn't get confusing. My system came with all of the logical units configured for me.  I have not shut it off since I installed it and I intend to keep it running 24/7 with my telnet BBS and my Swiftlink.

If you used to own a Lt. Kernal, you want this thing.  If you never got your chance to get a Lt. Kernal, you want this thing.  If you own a commodore 64 or 128, YOU WANT THIS THING! Thank you mytec for making this system from all of us who've waited so long. "The LTK is BACK!"

Q&A from previous buyers:

Question: Hi. I owned 2 ltk's and was wondering if the dos in this is similar to the lieutenant kernal?

Answer: Hello, the 7.3 DOS commands are nearly identical with very few exceptions.  There are many improvements and additional functions that have been added.

Question: I used to own an Lt.K and had to modify my xetec interface so I could use my turbo 232 with the system. Do I still have to do that with this new system? I had a problem that I can't remember specifics about when I used my novaterm and wonder if that is going to be a problem. Can you tell me if it would work with novaterm? At any rate, nice to see a new commodore product arrive on the market.

Answer: You probably had a Revision "B" Host Adaptor from Xetec. This required manual modification so it could use I/O port #2 (DF00-DFFF).  The later Revision "C" Host Adaptors were equipped with an I/O port jumper on the front, allowing selection of both ports 1 (DE00-DEFF) & 2 (DF00-DFFF).  The Rear Admiral Host Adaptors have the I/O selection jumper onboard and will easily allow this selection for you. Novaterm was written to only look at Logical Drive 0, since it was designed only for boot from floppy disk, so when used with an LTK it could not load from other Logical Units by default. Many people would hack the Novaterm program itself to allow load support from other LU's.  The easiest solution was to place the Novaterm program and associated files on LU #0 and then invoke the "USER" command to isolate the Novaterm files from the rest of LU #0's content.  This solution still works fine with the RA and presents no problems to Novaterm operation. The "USER" command is a great feature for "sub-directory" management of files, since any LU can have up to 16 "USER" assignments.  The "USER" and "DIR" commands of the LTK/RA Systems are very powerful and the new S.M.A.R.T. feature puts ICEPIC and Super-Snapshot to bed.  Thank you for your questions and we are very proud to present an all-new Commodore product to bring the "thinkers" back online.
