+TheBF Posted September 15, 2020 Share Posted September 15, 2020 I got the board. Looks like the new postmaster general is really making a difference. It only took 1.5 months to get from Texas to the great white north. 1 Quote Link to comment Share on other sites More sharing options...

Okay, so technically not Canadiastani, but still pretty close. Ya. I am way out there in the middle of nowhere, a 60 minute drive from Port Huron Mi. (Ok so maybe Port Huron is not NY City but hey. It's USA) Question: Where do I find the latest DSR and loader program for this beautiful blue play toy that I have here? Answer: I found Fred's site and downloaded V14.

+TheBF Posted September 16, 2020 Share Posted September 16, 2020 In other news... I powered up the card and looked at the DSR RAM in Forth. Works fine. Filled it up with data and erased it etc from the command line. I noticed that the 5V heat sink runs really hot. (I took it off and reinstalled it with some heat sink compound just to maximize heat transfer) Build a floppy disk with the DSR and loader.

I found it and ran the IDELOAD progam. Got all passes so good work by you. I have an old 80Gb IDE drive that I know works cuz I put Linux mint on it for fun. Should I be able to run CALL IDEST in BASIC with no drive connected but the board loaded? Neither E/A BASIC nor XBASIC can find the sub-program.

Shift838 Posted September 16, 2020 Author Share Posted September 16, 2020 Once you load the DSR you should be able to do a CALL IDEST You do not need a drive hooked up to run the command. Quote Link to comment Share on other sites More sharing options...

Shift838 Posted September 16, 2020 Author Share Posted September 16, 2020 are you running my 838 clock module or the standard BQ4847 ? I don't recall if you purchased both.. Quote Link to comment Share on other sites More sharing options...

BQ4847. I just went to reload the DSR and I tried to set the clock. It said the DSR was not loaded so the RAM did not retain the load. I will try it again Quote Link to comment Share on other sites More sharing options...
+TheBF Posted September 16, 2020 Share Posted September 16, 2020 Works if I don't power down the PEB. Battery dead in the BQ4847? Quote Link to comment Share on other sites More sharing options...
Shift838 Posted September 16, 2020 Author Share Posted September 16, 2020 it should not be. They were all brand new. of course old stock. So if you have voltmeter. Vout is pin #1 ground is pin #14 check to see if you are getting 3v between those 2 pins. Quote Link to comment Share on other sites More sharing options...

+TheBF Posted September 16, 2020 Share Posted September 16, 2020 Just to confirm that the card is loaded from another piece of S/W, here is a memory dump from Forth without shutting off the PEB. Looks like a DSR header to me. Working on volts... Quote Link to comment Share on other sites More sharing options...
+TheBF Posted September 16, 2020 Share Posted September 16, 2020 Out of the socket it slowly crawls up to 2.74 volts with a 40Mohm meter. (If memory serves) In socket it drops to 2V. It seems like something loading the chip on the board. ? Edit: Pin 1 to Pin 14 show 268K ohms with the chip removed. Quote Link to comment Share on other sites More sharing options...
+TheBF Posted September 16, 2020 Share Posted September 16, 2020 If the schematic is accurate it looks like Vout is powering U23 all the time. That doesn't sound right. The battery RAM would normally not power anything external would it? Quote Link to comment Share on other sites More sharing options...
Shift838 Posted September 16, 2020 Author Share Posted September 16, 2020 the battery does power the SRAM (U23) constantly as that is where your DSR is loaded. Quote Link to comment Share on other sites More sharing options...
+TheBF Posted September 16, 2020 Share Posted September 16, 2020 Ok. Now I get it. I thought the clock had SRAM built in. So I suppose I could hay wire a 3V battery onto the board and solve the problem. Or should I just get one of your clock boards? (gotta run for the evening) Quote Link to comment Share on other sites More sharing options...
Shift838 Posted September 16, 2020 Author Share Posted September 16, 2020 (edited) if you wire a battery on it then you will also need a diode or a FET in series with the battery to help ensure to protect the battery from getting a surge of power and exploding. At least that's how I understand it. Be safe.. Buy my board! ? Edited September 16, 2020 by Shift838 1 Quote Link to comment Share on other sites More sharing options...
+retroclouds Posted September 27, 2020 Share Posted September 27, 2020 Have to do more testing, but have the same issue with the first card I tested. DSR needs to be loaded again when I turn off the PEB overnight. Guess the battery in the BQ is half-dead. It’s not a very big deal as loading the DSR goes real quick with Fred’s FGROM IDE loader cartrdige image. But obviously it means I need to set the time again as well.

The BQ clock ship seems to have died and is no longer recognized, rendering the IDE card useless. Not a good day... Quote Link to comment Share on other sites More sharing options...
