View Full Version : Tall Tree System JRAM-AT3 HELP

September 10th, 2010, 04:31 PM
A couple of years ago got a Tall Tree System JRAM-AT3 memory printer io card for free. It has 2megs of extended memory on board. Because I never had any docs or drivers I put in a drawer. Last week I got a driver disk that looks promising. Put the card in my test system which is an old 5170 and it posted fine after adjusting the setup settings. I'm sure it would back fill the memory if I could decode the switch settings.

There seems to be zero info anywhere in the world, real or imaginary, about this card. Several of the same card seems to be on fleabay so they were around at one time but no docs to be found anywhere.

I was hoping to get more info on the driver disk but just software. It does include the .ASM source files along with the executable files. Doc's on how to use the files would have been nice but I found no help.

So... HELP.

I also have one of the Tall Tree JRAM-AT3 cards, just spent a few minutes digging it out of one of my parts boxes.
I have never tried this in a PC, I got it with a bunch of stuff a few years ago, no software-no docs.

This also has an add-on card , looks like maybe a clock and serial port.

Included a few pics with the switch settings on mine.

I'd like to get a copy of the software.

You got yours cheap :-) I paid $1 for mine

I'll be happy to zip the files up but without doc's on how to use them were still dead in the water. I can use mine as generic 2 megs EMM with no back fill. FYI my RP3 switch setting is the same except for #1 which I have in the "ON" position. I tried it in the off position it did change the memory setting but I so far am unable to determine it and set it correctly in the CMOS.

My daughter card is different. I have the "JLASER-3" daughter card.

Just went searching for jlaser-3 and found this.

Jlaser Plus memory expansion board and printer controller
Article Abstract:

Laser printers that do not include a full megabyte of memory, and therefore can not print full page graphics at 300 dps, can be enhanced with the Jlaser Plus from Tall Tree Systems. The Jlaser Plus has a JRAM-3 memory expansion board giving a PC up to 2Mbytes more RAM; there is also a 'piggyback' board that acts as a printer controller. The product works with printers that are based on the Canon LBP-CX engine including the following: Hewlett-Packard's LaserJet and LaserJet Plus, not including the Series II; Canon's A-1 and A-2; Cordata's LP-300; and Apple's Laserwriter, Laserwriter Plus, and QMS series. The product can increase printing speed because its connection, through a video interface, transmits data faster than a serial or a parallel port can, and because the printer does not wait for its own controller to build an image. Scanning speed also benefits from the faster interface, as well as from the increased RAM.

If the diskette contains device drivers you should try googling the device driver filenames.
You may find some config.sys or autoexec.bat examples that use those drivers.

Interesting idea! I surprised I didn't already do it.

I found nothing of usability anywhere.

Here is the files that were on the JRAM disk that I got. If any of them prove helpful please respond here. JRAM.ZIP (http://www.thegrumble.com/dl/JRAM.ZIP)

Sorry for the delay in posting I had a probem then got sidetracked then forgot... Old age Sucks!

All I can use it for is a back fill for now.

Hi, I'm new here in the forum. I' know this thread is pretty old, but it's the only thing I found on the web. I also have the JRAM-AT3. Unfortunatly I dont have the JETDRIVE/JSPOOL driver software to use the full functionality. Can anybody help? In exchange i could offer a copy of the complete manual.

I found some software on a hard drive from a box of parts I bought from someone here.

This was in config.sys


Files are JBOOT.BIN
(c)1984,85 Tall Tree Systems. Ver 3.41

(C)1984,85 Tall Tree Systems .JDRIVE RAM Disk Ver 3.21

(c)1983,1984 Tall Tree Systems. Ver 2.10

Just got some newer versions of the drivers from mikey99!!!

Just for future reference, I found this in a readme file.

Refer to the JRAM Manual Software Sections and/or the JLaser Manual for a full
description of the files on this diskette. The various JLASER.BIN files are for
different models of the JLaser interface board for laser printers:

JLASER.BIN for JLaser-1 (for Canon based LBP-CX laser printers)
JLASER2.BIN for JLaser-2 (for Ricoh 4080-E based laser printers)
JLASER3.BIN for JLaser-Plus (for Canon based laser printers & Canon scanner)

Each of these drivers controls both the JLaser interface and other EMS
software applications. Do not install more than one JLaser driver. All versions
of JLASER.BIN and/or JPAGER.BIN can only be used with JRAM-3 or JRAM-AT3. Use
JPAGER.BIN with these boards for EMS applications if you do not have JLaser.
Do not use both JPAGER.BIN and any version of JLASER.BIN.

JOUTXXX.COM files are various printing test files for use with with JLaser.
JINPUT.COM is a scanning test file for use with JLaser-Plus

JEMS.BIN is a new RAM disk driver that runs under EMS. You must install either
JPAGER.BIN or a version of JLASER.BIN to use JEMS.BIN.

JLAS166.BIN, JLAS266.BIN JLAS366.BIN, and JBOOT404.BIN are reserved for future
JLaser development.

As it been years from my last post in this thread, my total solution to using this board was pull all the memory chip and use them in another board which I could get the proper doc's and software for. That board is being used in a computer somewhere in my collection. The original jram card is pushing up daisies.

I had a PM to put that original software disk for the JRAM board This is v4.02 JRAM.ZIP (http://www.fastpictureframing.com/dl/JRAM.ZIP)

good luck,
