Myself, I am convinced that the 2150L is not a software from Mr Kaplan for the following reasons:

- any software from Julio Kaplan runs on a 6502 processor. The 2150L includes a sparc processor H8 (not 6502 compatible). I can not imagine Julio Kaplan rewriting his software just before leaving the company.

but Prisma and Blitz (both released 1990, according to CSS 6/90 the Blitz was developed by Julio Kaplan) also have a H8 CPU...
Prisma and Blitz have the identical playing program.

Some more points, that could be important:

Is the user interface of the 2150L identical to Prisma? (all Morsch programs were very different from Kaplan's regarding this)

How are the level settings?

BT-Tests could maybe show some associations between them.

With the Simultano program, Kaplan had already written a program for the LCD board (same as in Prisma and 2150L); i can't believe, Frans Morsch did that only for the 2150L...

Regarding the playing style: Maybe the Prisma program had been modified for the 2150L? (by Kaplan or another programmer)

And if you think, it is not a Kaplan program, you should compare it to Morsch's style...

How about playing strength? All modern Morsch programs are much stronger than Prisma; how is the 2150L?

Can you tell something about the ROM size in 2150L? In the Prisma it was 32K; Morsch's 32K program was the GK2100 (more than 200 ELO stronger than Prisma)

I do not own a 2150L, so i cannot answer this questions...

I agree with your thoughts and your concluding remark that no matter how you look at it....the game style of the 2150l is certainly not that of Kaplan. So with that said almost all of my other issues become moot.I also agree that there is no chance Kaplan would undertake a software rewrite before leaving!  With the conclusion we have then all other answers pretty much seem to fall in place and the problem is now solved....thanks again    Hondo

- the Saitek advertising is clear: this is a new software generation and a new game style (brute force oriented, supported by a faster processor).

For me it sounds clear that Saitek decided to stop to support the strategy of Julio Kaplan that was "good position" oriented.
I can not imagine that Julio started to build a brute force software just before leaving.

And as you know, the Saitek Serie developped by Frans Morsch is allways based on risc processor that are variant of the H8 serie.

But of course I may be wrong. 
One point is sure: the game style of the 2150L has nothing to do with former Julio Kaplan's game.

Hi Bobossee... I think you are probably correct that the 2150l is a Prism but there are annoying subtle differences that either are mistakes or are indicative of a difference. The Saitek Prism is said to have a 10 mhz processor speed the 2150l is rated at 8 mhz. The prism on the same German site is rated at 1735 and the 2150l at 1720. This site does cross reference each game as being in some way associated. The one issue that I would really like to clarify is who programmed the 2150l. Is it Kaplan or Morsch? If kaplan really did leave Saitek in 1990 than it's a no brainer and this was programmed by Morsch.  Reason being that this games APPEARS to have been developed AFTER Kaplan left Saitek. Only problem is that I can't find definative development dates. Seems that some sites list 1990 and some list 1992 ! So you see some of the remaining issues and for the most part don't amount to a "hill of beans" but is more of want to know just for personal satisfaction! Thanks for your help...    Regards    Hondo

On the Saitek Catalogue, you can read that the Saitek Prisma has an opening library of 17000 moves. And the 2150L is a Saitek Prisma. So 17000 moves is probably right.

I checked the user guide of the go 2150L, there is no indication on the opening library size.
Maybe there was something indicated on the game box but I do not have this game anymore. So I can not check.

I do not remember why I put 6000 on my site. It's probably a mistake.

Hi all .... I just recently acquired a R/S 2150l (not the GO Ver.) for my collection. It seems that there are mixed or differing thoughts / views about who the actual software designer was (Kaplan vs. Morsch). Also unresolved for me is the opening library.... is it 6,000 half moves or is it 17,000 as Wiki suggests. I have read comments here and on other sites but w/out feeling afterwards that this issue is resolved! I know it is an old debated one and maybe resolved for many here. I guess I am looking for one of the many knowledgeable collectors here to difinatively say ....  this is the most current reliable info. out and the consensus is ..... LOL ! Thanks and regards to all.........    Hondo
