I'm instersted - what a difference between this two modifications?

I have real CPC-300E, and I compared this with openMSX emulation of CPC-300. I see some difference:

CPC-300:

- It show date/time on logo screen (some Korean symbols);
- Then it show Basic version screen;
- Then MSX-TUTOR starts.

CPC-300E:

- It does not show date/time, as well as memory size, on logo screen (logo is same);
- Then it show Basic version screen, it same too;
- Then Basic starts. No MSX-TUTOR.

I first assumed, that 300/300E is versions for different countries, but both versions have Korean logo, and MSX-TUTOR shows something in Korean; 300E have Korean keyboard (in manual also said, that RF-output is available only on Korean version, and my 300E have this output).

btw, if ROM's of 300E not dumped, and if they can be saved from computer itself (from Basic, or loaded program), I can do it.

I checked MSX Hardware List, and saw only CPC-300 in list, with photo, which is different from my 300E. So I provide additional information:

Black/gray case, red LED on language key (like CAPS key), labels on keys is differs from CPC-300. Photo (feel free to use, I plan to use it into ru.wikipedia article):

img151.imagevenue.com/loc598/th_26032_computer_daewoo_cpc300e_122_598lo.jpg

Sorry, I forgot to take photo inside (can make it later), so for now just text description:

No sockets for joysticks, and no elements on board for it (diodes, register).
No RTC, no battery (but empty place for it)
RAM: 4x53C464 and 2x53C464 close to ROM's (so, 128K VRAM and 64K RAM, I suppose). Another two empty IC places close to that 2 chips.
ROM: Three ROM's with stickers on top: HAN 7.15 12CD, OS7.7 5CC1. CPC-300E EXT V1.0
'Chipset': DW64MX1 and another big IC with heat sink (looks aluminium)
On back side of keyboard and AC transformer are stickers with label CPC-300C
All IC's, include Z80 and AY marked as 1989 year

On bottom of case are sticker with label: 220V, 50HZ, 21W (also here is switch 220/110).

Connectors: RF output, AV output (on additional board inside), RGB output, Color/BW switch, Channel switch, Tape In/Out, Printer port, Extension port.

Color system is NTSC.

It's interesting. Big smile

OK, I have CPC-300 and I couldn't find any differences between my CPC-300 and your picture.
My CPC-300 is just look like yours but there was white-boxed version of CPC-300 too.

and inside the machine,

No sockets for joysticks, and no elements on board for it (diodes, register). => CPC-300 has complete circuit for joysticks.
No RTC, no battery (but empty place for it) => As you know, CPC-300 has RTC on its board.
RAM: 4x53C464 and 2x53C464 close to ROM's (so, 128K VRAM and 64K RAM, I suppose). Another two empty IC places close to that 2 chips. => CPC-300 has 128K main RAM, 128K VRAM
ROM: Three ROM's with stickers on top: HAN 7.15 12CD, OS7.7 5CC1. CPC-300E EXT V1.0 => I think these ROMs are same as CPC-300.
'Chipset': DW64MX1 and another big IC with heat sink (looks aluminium) => DW64MX1 is gate array which includes same logic of i8255 and some other logics. big IC with heat sink is VDP (V9938)

and connectors are identical, I guess.

But I have no idea about CPC-300E, sorry. Tongue

Is it possible to guess that E in CPC-300E stands for "E"urope? LOL!

or, what about CPC-300E for "E"ducational purpose?

Joysticks sockets itself is present on CPC-300?

big IC with heat sink is VDP (V9938)
I heard before, that Korean machines, include CPC-300, has modified VDP, named (not officialy, AFAIK) 'V9948', with additional mode. It's true or not?

Your machine have LED in key, which right to SPACE (with two hieroglyphs on it)? Can you type Korean symbols on CPC-300?

Is MSX-TUTOR present in your CPC-300?

Is it possible to guess that E in CPC-300E stands for "E"urope?
I think, Korean language not so popular in EuropeSmile

or, what about CPC-300E for "E"ducational purpose?
Yes, it seems more like true. But this machine has no built-in network hardware, that some strange for educational machines without disk drive.

One more question: in MSX Hardware list said, that CPC-300 has light pen connector, but my CPC-300E does not. It really present in CPC-300?

Hi Shiru Wink

Joysticks sockets itself is present on CPC-300? => Yes, they are. CPC-300 has two joystick ports.

I heard before, that Korean machines, include CPC-300, has modified VDP, named (not officialy, AFAIK) 'V9948', with additional mode. It's true or not? => It is said that some version of MSX(game console type) has different VDP, but I couldn't find any further information. CPC-300 has V9938 as its VDP, AFAIK.

Your machine have LED in key, which right to SPACE (with two hieroglyphs on it)? Can you type Korean symbols on CPC-300? => Yes, there is LED in the key. I can type Korean characters on CPC-300, I bought it in Korea, and, since I'm Korean, I'm sure what I was typing with my MSX is Korean.

Is MSX-TUTOR present in your CPC-300? => Yes, there is MSX-TUTOR.

One more question: in MSX Hardware list said, that CPC-300 has light pen connector, but my CPC-300E does not. It really present in CPC-300? => Well, the real machine is at other place now, I cannot check if there is. But I think there was a light pen connector.

Looking the picture you've posted, the machine has exactly same outfit of CPC-300, so I think it could be some customized or reduced version of CPC-300. LOL! Anyway it looks very rare.

Big thanks for your answers, cronos.

It is said that some version of MSX(game console type) has different VDP, but I couldn't find any further information. CPC-300 has V9938 as its VDP, AFAIK.
But V9938 does not contain anything like 'screen 9' mode, right? I checked this on my CPC-300E, and yes - there is screen 9 (high-resolution, green-black screen)

Yes, there is LED in the key.
Hmm. So now I wonders, which modification of CPC-300 is on photo at MSX Hardware List then (http://www.msxarchive.nl/pub/msx/photos/hardware/Daewoo_CPC-300.jpg)? There is no LED, and this key named 'CODE'.

and, since I'm Korean, I'm sure what I was typing with my MSX is Korean
Wow:) Sorry, that I has not looked in your profile.

Yes, there is MSX-TUTOR.
It starts right after machine power-on? Or it need to be called somehow? Can it be called manually?

Looking the picture you've posted, the machine has exactly same outfit of CPC-300, so I think it could be some customized or reduced version of CPC-300. Anyway it looks very rare.
Yes, it now looks exactly as reduced version (less memory, some features removed).

Surprisingly , but it's not rare there, in Russia. There is not many MSX'es at all, only Yamaha's (which was used as educational machines in many schools in mid of 80th), and Daewoo's machines. By now, these Daewoo CPC-300E, CPC-400 and CPC-400s is most common (Yamaha's models now rare, especially 'teacher' version). Some owners even sells they by parties of 10-15 machines, new and sealed. I got this (used) CPC-300E just for $10 last year (and CPC-400s with monitor for $50). AFAIK, these machines was planned to replace old Yamaha's and our own 'wonders of electronics' like Korvet, UKNC in schools. But then PC came..

Because you is Korean, I have some more questions for you:)

These Korean symbols is named 'Hangul'?
On logo screen is written something like 'MSX2 IQ2000' in hangul?
Can you translate meaning of symbols in Basic version screen, and on key, which switch input mode?

Additionally: video with CPC-300E power-on sequence and screen 9 (DivX5): http://rapidshare.com/files/11578831/cpc300e.avi.html (2.10MB)

No problem, Shiru.

You're right. V9938 has nothing like 'screen 9' because 'screen 9' is like "pseudo mode". On Korean edition of CPC-300 and CPC-400(both are MSX2) has screen 9 but that mode is actually screen 6 with software driver for displaying Korean characters. When you enter "screen 9" after the basic prompt, Hangul ROM in Korean MSX interprets this , turn VDP mode to screen 6(graph 5 or something for VDP) and sets some hooks(like software interrupt) referring to handler routine for Korean. Then software routine in Hangul ROM "draws" Korean and English characters on screen 6 when you type keyboard, "drawing" means drawing because screen 6 is bitmap graphic mode. Because of this procedure(this was made when MSX2 were shown), when MSX2+ was built they designed MSX2+ ommitting screen 9 to prevent confliction. Actually it is no matter of VDP modes, but basic screen modes.

Hmm. So now I wonders, which modification of CPC-300 is on photo at MSX Hardware List then (http://www.msxarchive.nl/pub/msx/photos/hardware/Daewoo_CPC-300.jpg)? There is no LED, and this key named 'CODE'.
I think the picture is edition for exporting out of Korea. Korean CPC-300 has "Hangul" key where the "Code" key located and the key has LED indicator. What you see in the picture you mentioned are European characters like pound, umlaut, etc. Korean edition has Korean characters instead of those characters.

It starts right after machine power-on? Or it need to be called somehow? Can it be called manually?
With default configuration, the MSX-TUTOR starts right after the power-on screen. It is MSX-BASIC program so that you can call the program by exchanging slots, but you have to write some machine code to look into the slot. In general BASIC mode, we cannot call the program after MSX-BASIC started. You can only turn-on and off wheather it starts after booting or not, by typing MSX-BASIC command. If you type "SET SYSTEM 1" on your BASIC prompt, the MSX-TUTOR will be skipped on next boot, to set to default, type "SET SYSTEM 0". This setting will be kept by RTC and back-up battery. Or just press "SELECT" key when the tutor is shown to skip it and see the BASIC prompt immediately.

Surprisingly , but it's not rare there, in Russia. There is not many MSX'es at all, only Yamaha's (which was used as educational machines in many schools in mid of 80th), and Daewoo's machines. By now, these Daewoo CPC-300E, CPC-400 and CPC-400s is most common (Yamaha's models now rare, especially 'teacher' version). Some owners even sells they by parties of 10-15 machines, new and sealed. I got this (used) CPC-300E just for $10 last year (and CPC-400s with monitor for $50). AFAIK, these machines was planned to replace old Yamaha's and our own 'wonders of electronics' like Korvet, UKNC in schools. But then PC came..
Wow, you said you can buy CPC-400s now? new and sealed? I WISH I COULD BE THERE TO BUY THOSE MSXES! LOL!

Because you is Korean, I have some more questions for you:)

These Korean symbols is named 'Hangul'?
On logo screen is written something like 'MSX2 IQ2000' in hangul?
Yes, Korean letters are named "Hangul".
Sure, the logo says "IQ(thumb)2000".

Can you translate meaning of symbols in Basic version screen, and on key, which switch input mode?
it says,
MSX BASIC version 2.0
Copyright 1985 by Microsoft.

MSX "Hangul" version 3.00
Copyright 1986 by "Daewoo"

On the key which switches input mode between English and Korean, "Hangul" is printed.

may this help. ;)

Very interesting, people!

By the way, Shiru, I have here a Russian version of the Sony HB-F9P. See
http://www.msxarchive.nl/pub/msx/photos/hardware/Sony_HB-F9P_Russian_1.jpg

I also updated the hardware list a bit. More corrections are very welcome!

Wow, you said you can buy CPC-400s now? new and sealed? I WISH I COULD BE THERE TO BUY THOSE MSXES!
I saw many messages on boards, and items on online auction 'Molotok' (russian alternative to eBay), from selles from different cities - both with used and new CPC-300E and CPC-400s, from 1 to 10-15 units. This was in 2004-2006. At current time I can't find new CPC-400s at auction, but some used ones still there, and I think, new will be on auction again (some guys sells these computers all that 2 years).

Man, which sold me my CPC-400s and CPC-300E, also said, that he has also some of CPC-300E, and his friend has too. Also I know many people, who have both models of Daewoo, or one of them, and I personally saw 4 machines last year (two CPC-300E, one 400, and one 400s).

Unfortunatelly, it will be very difficult to buy one computer from other country, than Russia, and shipping price will be great, I think.

may this help.
Yes, great thanks! I already used some information in my article for ru.wikipedia, and also translated this arcitle to english, by someone request in changelog: http://en.wikipedia.org/wiki/Daewoo_CPC-300 (please proof-read this, if you can - I know english a very little).

By the way, Shiru, I have here a Russian version of the Sony HB-F9P.
Wow, I never saw this model before. Today I searched in Runet, and found two messages from one man from Moscow (where I live too), who sell SONY HB-F9P (Russian version indeed) with MSX-Audio for ~$60.. Messages dated 17/12/2004 and 15/6/2005, no newest ones, so I think, he sold it now.

At present moment, I didn't find any information about usage Sony's MSX'es in Russian schools. But I found this short information in internet: '..As you may probably know, there is a Sony HB-G900P in the russian space station MIR..'. Shame on me, I didn't know that;)
