Latest additions to the X68000 Wiki
« on: December 03, 2011, 11:10:37 am »
 Just to be able to keep track of things please post links to your additions to the almighty X68000 wiki here.

Latest additions are:

X68000 Compact XVI internal SCSI and CF card mod by Caius
http://gamesx.com/wiki/doku.php?id=x68000:internal_scsi_and_cf_card_mod

Hardware data - "System overview" and "Expansions" sections have received some major additions. It is still a work in progress so be prepared for some raw unrefined Engrish ;)

http://gamesx.com/wiki/doku.php?id=x68000:system_overview
http://gamesx.com/wiki/doku.php?id=x68000:x68000

This data was kindly snatched from Japanese site located at http://www.geocities.co.jp/SiliconValley-SanJose/6808/
If the webmaster of the before mentioned site sees this I hope that you will be able to forgive me for I have credited your site in each Wiki article whose info I have obtained from your site.

Any suggestions and harsh constructive criticism are welcome.

Keep the scene alive!

This is great stuff, thanks Eidis.

I sent a question some time ago regarding connecting my DATA CardDock to my XVI compact and the update here is that I am having a terrible time finding a SCSI cable that actually matches the XVI compact SCSI connector. It looks like a HPDB50 but it really isn't... I looked all over the web for info on this and find none. So now I am focusing on trying to get a 5.25 drive setup in one of my Win98 machines and see if I can generate a boot disk for my Expert.

If anyone has any extra info on the XVI compact SCSI connector please post here!

Thanks

 Magic Knights tutorial on file transfers using null modem cable has been updated with information on how to go beyond 19200 bps and achieve 38400 bps in file transfers. The good news are that the cable for which I released pinouts on previous day is compatible with this method. Check it out, starting from chapter 10:

File transfer between Windows PCs and X68000 machines using a null modem cable
http://www.gamesx.com/wiki/doku.php?id=x68000:file_transfer_between_windows_pcs_and_x68000_machines_using_null_modem_cable

Keep the scene alive !
Eidis

Update: Eidis's ambition (Nobunaga ?) does not end here. It seems that there is a way to achieve higher speeds, even up to 115200 bps with a patched MuTerm, tmsiop and a slightly modified null modem cable with 1.8432MHz oscillator using (pin 17) RT signal line. I'm out of 1.8432MHz oscillators so I'll post updates when the ordered one arrives.

This iplrom package is wrong, please see my post : http://nfggames.com/forum2/index.php?topic=4845.0

And it seems I've misspoken about inside/ouside x68000.
I only had Inside x68000 since a long time now, but never upload it because of probable legal issue... Really sorry guys !
But I've quickly compiled it into PDF, while perfoming some OCR on each pages (usefull for copy/paste and translation). I've also start to draw schematics of an ACE core. Maybe I can upload them as a compensation ?  :)

And I could also kill for this damn Outside X68000 !!!!  :D

Today is a very special day and I mean very very very very very special day thanks to the cooperation of BlueBMW and Lydux. BlueBMW was very kind to spend his time and money hunting these down and Lydux made sure that this info gets scanned with dignity.

Cue music:
https://www.youtube.com/watch?v=cWnmCu3U09w

CZ-147 - X68030 Service Manual
http://nfggames.com/X68000/Schematics/CZ-147%20-%20X68030%20Service%20Manual/

Outside X68000 - Schematics
http://nfggames.com/X68000/Schematics/Outside%20X68000%20-%20Schematics/


Here are some words from Lydux:

- X68030 service manual
116 pages, the most interesting and hardest part. It contains hardcore hardware infos for both compact and twin models, some troubleshooting procedures, electrical block diagrams, case disassembly, FULL SCHEMATICS, custom chip pinouts (however no pinouts descriptions), plus others stuffs. Schematics have been reworked because those are copy of copy of copy... The quality was bad, but I've managed to recover unreadable part and they are now fully usable.
I also want to point out that about 90% of the stuff here are retro-applicable to earlier x68k's models.
94 files, scanned in gray scaled @ 600 dpi in TIFF format. The result are about 110 MBytes.

- Outside X68000
This book comes with a large amount of schematics in very large A2 sheets. That what I were waiting for :
  * CZ-600E : the full schematics of the original X68000 ! Hardcore stuff in 4 x A3 sheets.
  * CZ-634C-TN & CZ-644C-TN : this is full schematic of the X68000 XVI for both models ! 6 x A3 sheets needed.
There are also schematics of about all Sharp released addons board : RAM extension boards, FPU accelerator, MIDI, additionnal RS232, external SCSI, ... For 16 addon boards exactly.
However, I'm a bit disappointed about the books itself. It's not as interesting as I though. It just provides a picture of each cards, explains what they do, and eventually how to program them. That's all... No block diagrams, pinouts description or timings infos... :/ There is also a bit of infos on about how to build your own card as well.
So, I haven't managed to scan the book yet, but all schematics are done.
26 files, scanned as gray scale @ 600 dpi, TIFF format. Result is 62MBytes.

Outside X68000 (book) will come later.

P.S. Comming soon the missing pages of X68030 service manual

Keep the scene alive !

X68000 personal computer is called, "X68K" or "no good good" is called, is the PC that are loved by many people today.

Thank you guys!This is an awesome job from you, now the scene is more clear and crisp and  our repairs will be more easy... :)

P.S.
Are there also schematics of internal FDDs?

Hi !

Thank you guys!This is an awesome job from you, now the scene is more clear and crisp and  our repairs will be more easy... :)

P.S.

Far more easier : with the help of those schematics, it only took a single hour to me to find the problem and fix a black screened CZ-600CE.
Unfortunatly, no FDD schematics or infos. You are looking for extra pinouts on PRO's ones, right ? I promise you we'll spend some times on this (btw, I've restarted our "project" :) ).



Anyway, here is a quick tour about all schematics coming from Outside X68000.
Feel free to ask for any infos about them.

CZ-6BE1
Internal 1MB RAM addon for original X68000 (CZ-600CE).

CZ-6BE1A
Internal 1MB RAM addon for ACE series.

CZ-6BE1A (A)
Internal 1MB RAM addon for ACE and PRO series.

CZ-6BE2A
Internal 2MB RAM addon for XVI (twin-tower). There is also 2 extra ROM sockets to change the bios.

CZ-6BE2D
Internal 2MB RAM addon for XVI Compact. Also provide a socket to put an FPU (MC68881).

CZ-6BE2B
Extra 2MB RAM addon to mount back on CZ-6BE2A or CZ-6BE2D.

CZ-6BE2 & CZ-6BE2C
External 2MB RAM addon. I don't get the exact difference yet, but it's probably related to the stock amount of RAM you have.

CZ-6BE4 & CZ-6BE4C
External 4MB RAM addon.

CZ-6BP1 & CZ-6BP1A
The official FPU accelerator board featuring an MC68881. I don't see any differences between those 2 versions. So, it's probably just a PCB fix.
I found this one really easy to build and will probably try to design a DIY clone one day.

CZ-6BM1
This is the well known MIDI addon board ! Equipped with the Yamaha MCS (YM3802).

CZ-6BN1
This one is an external addon board which provides 2 unidirectionnal 8bits buffered lines, plus some control lines presentable on a DB37 connector. Does use the very common 82c55. Designed mostly for various small and low speed hardware addons (eg: hand scanner).
I've always said this kind of board is a very good start point for those who want to give a try into hardware programming.

CZ-6BV1
Multi-output TV converter and color booster. The idea is to transform the video output signals from the x68k to a 15Khz NTSC capable only TV presentable on traditionnals composite and S-Video connectors.

CZ-6BS1
The well known official external SCSI-1 addon board equipped with a MB89352 scsi controller.

CZ-6BG1
You have probably never heard about this one, and not even interested into getting one. It will allow the X68000 to communicate on a GPIB (General Purpose Interface Bus). An old but always used standard mostly used by industry to drive various equipment in a network fashion.
Try googling for GPIB and IEEE 488 if you want more details.

CZ-6BF1
RS-232C addon board ! It will add 2 extra serial port to your X68000. Feature the exact same z85c30 as the one you can found inside your x68000 and does work exactly in the same way.

CZ-6BC1
A FAX ! You are probably unable to use it nowadays, but it's interesting to know that a FAX emitter/receiver has existed for the x68000.

CZ-6BU1
I don't exactly know if this card has been designed for a specific purpose. Seems to me it's nothing more than a simple general purpose I/O board for interested programmers, just like the CZ-6BN1 but without dedicated device (82c55). Designed only with simples and cheap logics, buffers, latches and flip-flop IC.
Does presents a 50 pins IDC connector on the back orgranized as :
  - 2x8bits buffered input lines
  - 2x8bits buffered and latchable output lines
  - Some control lines for the 4 ports
IMO, also a good card to begin with hardware programming.



Hum... I don't remember how many times I have done this, but one more will not hurt : thanks you BlueBMW for providing me those dangerous stuffs ! :)

Ha, with all of the schematics, makes me wonder how feasible it would be to build our own boards. (probably still near impossible.)
