I see where you put the additional 8 drams. Is that all you have to do? ------------ Category 11, Topic 2 Message 2 Tue Oct 25, 1988 D.RAY1 (Forwarded) There is a text file here on GEnie that details how to upgrade your 1764 to 512k. It is file # 4339 library 1. there is also a ramtest program in the same library to test your newly upgraded REU, it is file #4374. both files were uploaded by TBEREMAN. I have done a 1764 upgrade and it is not that hard. You need to have some skill using a soldering iron. ------------ Category 11, Topic 2 Message 3 Tue Oct 25, 1988 COLOR64BBS [Greg Pfountz] (Forwarded) Yes, you just add the 8 extra ram chips - piece of cake. It is recommended that you actually solder in sockets, then plug the chips into the sockets - less chance of blowing a chip by a novice with the soldering iron. Ram dos is smart enough to see the extra ram and will automatically show you the 2011 blocks free. ------------ Category 11, Topic 2 Message 4 Thu Mar 23, 1989 C128.CPM [Bill] at 07:59 EST Software Support International is selling 1764's that have been crammed with chips, making it a 512K REU for $199.95. They also will upgrade your 1764 to 512K for $75.00. Thank you, H.Herman1 (Howie) for this info! ------------ Category 11, Topic 2 Message 5 Thu Mar 23, 1989 D.RAY1 [Dale] at 18:46 EST Bill, If I remember right the price on that 1764 upgrade is $119. Also, SSI is keeping the heavy duty power packs that come with the 1764s and selling them seperately. I think the ad I saw said $24.95. ------------ Category 11, Topic 2 Message 7 Fri Mar 24, 1989 THX1138 at 03:03 EST Yes I just ordered the 512k 1764 and they said they were shipping Friday (today). The price is $199 for the 512k 1764(less heavy duty C64 power supply) and $124.95 to upgrade your own 1764. It is a little pricy, but considering that the 1750's are not being produced it is the only game in town. I let you know how the 512k 1764 turns out when I receive it next week (I hope). Software support 800 356-1179 or 206 695-9648 to order, the later number is a twenty four hour a day, order only no info, line. Their hours are 9-5 PST. ------------ Category 11, Topic 2 Message 8 Fri Mar 24, 1989 C128.CPM [Bill] at 15:51 EST Dale and THX are correct. 199.95 for the 512K 1764, and 124.95 for updating your 1764!

If the past problems with <RETURN>, <S>croll, <Q>uit ?s the 1700/1764 are any indicator, the 1764's might be hard to find and in short supply at first. Some stores that *do* have them are selling them for $159.95 (or thereabouts). That seems about right for 256K, about midway between the 1700 (128K) and 1750 (512K). As was promised, the 1764 comes with a large (2.5 amp) power supply (vented and apparently repairable), and a disk containing the RAMDISK program, FILE COPIER, DOS WEDGE, DEVICE CHANGER, RAM UNIT TEST program, two DEMOS, and a GEOS WEDGE. The RAMDISK program can be used with the 1764, 1700, or 1750, and should be available here in the *FlagShip* libraries as soon as our Utilities SySop has a chance to download/test it. The RAMDISK emulates a disk drive, in that it is assigned a device number and you can RENAME, COPY, SCRATCH, NEW, INIT, VALIDATE, POINTER (for REL files), UJ, UJ0, UI, U0>CHR$(n) (where n=unit number). DOS commands *not* supported include: B-R, B-W, B-A, B-F, B-P, M-R, M-W, and M-E. It does support wild cards, SAVE with REPLACE, PRG/SEQ/REL/USR filetypes. The DOS interface to the KERNAL is through the standard indirection vectors for the following Kernal Calls: OPEN CLOSE CHKIN BASIN BSOUT GETIN LOAD SAVE INMI. The DOS INTERFACE BLOCK may be installed on almost any page in the system, provided it is *not* under any ROM's. The default is the page starting at $CF00 (207) during initialization, but you are given an option to change this. First impressions: WUNNERFUL! Naturally, many disk directory utilities such as DIR ASSIST and DIR MANAGER have problems dealing with the RAMDISK, but most programs just love their new 'home'. ARC runs *from* the RAM well, but will access the 1541 as drive 8 instead of the RAMDISK as drive 8. Haven't had much time to fool with the thing yet, so I'll leave it at that. (Thanx to THE DAILY EXCHANGE and ILLUSIONS BBS!) -=:[ Mike ]:=- ------------ Category 11, Topic 17 Message 2 Sun Apr 05, 1987 CHARRINGTON [Courtney] at 18:56 PDT Okay...it works with the 1750/1751. Wonderful. But (!) will in work in 128 mode. Bet not. So us 128 owners still have to wait for support on our machine. *sigh* Courtney ------------ Category 11, Topic 17 Message 3 Mon Apr 06, 1987 GBARRETT [VISION100] at 21:22 CDT Court, if I remember correctly (correct me if I'm wrong fellows...), the ONLY difference between the 1700/1750 and the 1764 is the current load and the new power supply. Memory management is the same in all of them, far as I know. Only thing...I believe the RAMDISK program IS 64-specific, so we 128ers have to wait...again... -GaryB ------------ Category 11, Topic 17 Message 4 Tue Apr 07, 1987 SPARROW.J at 00:39 EDT Gang, I asked Fred about releasing the C-128 version of the R-disk software again today, and again we are all still waiting for final approval from his bosses. I sware to you I am running up a huge long distance phone bill trying to persuade CBM to release this thing! --Sparrow James ------------ Category 11, Topic 17 Message 5 Tue Apr 07, 1987 MICHAEL.M [-:SysOp:-] at 00:39 EDT Just confirming that the RAMDISK program *is* 64-specific. (How long has the 1700/1750 been out??? GRR!) ------------ Category 11, Topic 17 Message 6 Tue Apr 07, 1987 CHARRINGTON [Courtney] at 06:20 PDT The RAMDISK will run on my 1750 *in 64 mode* which is a step in the right direction. I finished my taxes last night after making it device 8 and loading all the files into it. And yes...the file copy program is slow as hell (can't use a fast copy)...but the tax program when lickity-split after that. I can imagine what the 1750/51 would do in 128 mode. And Sparrow--thanks for the efforts! I know they will pay off sometime down the road. Courtney ------------ Category 11, Topic 17 Message 9 Tue Apr 21, 1987 CHUCK.WAGON at 22:59 PDT dsc Well, I got a chance to down load this little goody and run it through its paces and here's what I found. 1. A System reset (using the reset button as implemented on the 128) will cause a loss of all RAM-Disk memory. This is a disapointment as those of us who have utilized the 17xx CP/M mode RAM Disk capabilities have come to appreicieate. Also as most C=64 Commercial programs will not allow the user to reset or return to System this will greatly reduce the use of storing some programs in the expander. 2. On the Plus side it was a pleaseure to load a whole disk full of my favorite SID Player Tunes and not have to wait for those timley pauses between songs. However, though SID Player and Multi-Sid Player worked without a glitch, I was not able to get Sid Pic 2.5 to work. The program was not able to read any MUS programs on the RAM-Disk even though I had reset the RAM-Disk DU # to Unit 8. I did list the Sid Pic Program to see if I could figure out a way to make it run but was unsuccessful. Any help in this area would be appreciated. 3. I was able to load Slam Ball into the RD (RD = RAM-Disk) an run it but couldn't reset the sytem as noted above so tryng to store a bunch of your favorite games may be a problem. 4. A word of advise, As Courtney commented or inferred earlier, I suggest that you initiate the RD as unit #15 or any other unit# other than 8, copy your programs with the file copy program and then change your physical drive (1541, 1571, or what ever youre using) to #9 and reset the RD to unit #8. This is because most basic programs that load ML programs usualy make there call for the ML programs on DU #8 if you don't reset the RD Drive Unit # to #8 You will Crash the System or get a Device Not Present Error. The Alternative of course is to re-write the basic portion of the program if possible to make the call to the desired Unit#. Its a shame you can't Log In a drive like you can in CP/M and MSDOS Operating Systems. Overall I am sure that many users will find that the 1764 will give them a whole new dimension of use and power that the original designers of the C-64 never imagined. I have No doubt that Software Taking full advantage of this new tool will follow much quicker as the base of In...
