I need a new users guide to MDOS and the last 35 years

With thanks and appreciation to @jedimatt42, attached is a slightly modified version of MDOS / Geneve OS 6.50. 

 

The only OS change is that the default DSKx mappings (via REMAP) have been modified and a new CRC applied. 

 

DSK6. and DSK7. are now configured as "16-bit" ramdisks.   I also quickly tweaked some documentation, replaced CRACK128 with CRCOS, added FORM v1.23, modified the CYA title screen, and removed the (old) version of DU2K. 

 

GeneveOpSys650-redistributionpermitted2020.dsk 360 kB · 10 downloads

 

If someone could please add this image to WHT that would be appreciated.  The prior release may be archived or deleted, IMHO.  

 

 

DISK (1440 in size DS/DD) is working (int the PEB box is HRD3000+Rambo,

TI RS232, Geneve9640 v1. non-genmod, Corcomp Disk Controller DS/DD)

 

but

my HRD3000+Rambo is at CRU >1500 currently and no success so far with FORM123

it does not see DIR DISK8.  (and not sure if I need to do the Disk Utilities FDR change)

(also need to check if the HRD can be changed to CRU >1400).

 

Furthermore I have added GPL, GPM, GPN, GPO and AUTEXEC with TIMODE to the disk,

to load the GPL and TI-99/4A, that works fine, but cannot access DSK8.

I didn't see CRU >1500 in Matt's instructions. Use CRU >1400 and DSK6 to access it.   Do not set the card to >1500.  Drive numbers are tied to specific CRU addresses unless you use the OS to remap to a different drive number.

Yep, my page actually says near the top under limitations that you need use >1400...

Crubase >1400 should be used

I found the dip-switches (Set SW5 to ON only and it is on CRU >1400 now)

and YES!!! it is working now.  Slowly I get my TI + Geneve systems setup how I want it.

this is great. Hope the HRD works better with Geneve than I use with my TI.

 

Thanks very much for these instructions!

 

PS. In the manual below about HRD3000/Rambo

they refer to  LHDROS,  HDROS, CFG and RAMDOS needed ?

(I need to locate them somewhere, probably on the disk)

Good call-out and question.  MDOS contains all the necessary routines to use the ramdisk once it has been formatted.  LHDROS, HDROS, CFG, and RAMDOS are all old support programs that are no longer relevant.  Do not use these programs.   :)  

 

@Ksarul, we need to remove references to any of the old Geneve setup/programs from the HRD4000B construction manual, if that has not already been completed.

(I have not tested it) but if new 3x NiCD batteries are fully charged. How long can I leave the PEB box unpowered? (A few hours, 1 day, 1 week, longer) to avoid that I loose the whole boot setup config for Geneve on the HRD?

I've left mine off for weeks at a time and it holds the memory, but you can generally keep them that way for a few months. There is probably more drain from self-discharge than from current use by the HRD.

I think I've already removed all references to these software bits, but I will do another scrub to be sure. I checked the current manual. We made sure that the references to LHDROS, HDROS, CFG, and RAMDOS are identified as only useful for those still using really old versions of MDOS (1.23 or earlier). If you are using anything newer than that, they are to be avoided.

Are these batteries or rechargeables ?

 

Rechargeables. NI-MH batteries.

(See picture,  i saw another HRD picture which has battery holders kind of smaller fitting it together, i did not have space, but it all works now).

Okay that sounds promising, will test it! 

 

How long does it take to charge batteries via the PEB, same as a charger? Depends on he Amp? (i do not want to take out the batteries when the HRD is in operation, to keep data, but do faster harging batteries with an external charger).

Inching closer to gathering code and re-acquainting myself with my past work.  Tonight I formatted my Horizon 3000 under MDOS 7.00.  Not quite ready for a dev thread...soon.

This seems all to work fine for the last weeks, with having it being turned-off for a week, until now it nicely starts-up each time of the HRD

@arcadeshopper  @InsaneMultitasker @jedimatt42

 

Maybe the other MDOS disk can be updated to include the GPL files?

 

 

This MDOS 6.50 disk (1440. DS/DD) has the GPL, GPM, GPN, GPO files added, so that from MDOS you can go to the TIMODE 

(enter GPL from the MDOS prompt) and in GPL mode use DSK8. to load files of the HorizonRamdisk

 

AUTOEXEC2  need to be installed on the HorizonRamdisk and be renamed to AUTOEXEC

 

GeneveMDOS.dsk

 

PS. you will get a command error in MDOS as I try to use "CAPS ON" by default

      in the AUTOEXEC to start with uppercase characters (did not get it to work yet)
