How about the RadioShack Portable 1650L ?

Is the program also written by Kaare Danielsen ?

RadioShack Portable 1650L is a 100% clone of... ?

1650L is not HD6301V1.
PCB photos here, epoxy blob, but not enough pins for it to be a 6301.

Here it says Kaplan, and 68HC05

Hello Hap,

The photo is not good, but I can count 40 pins, like the 6301V.
I have a 1680L fast response, with I think the same microcontroller, but I can't play after power on.

Cordially.

Hello,

It seems that RS-1650L and RS-1680L has the same program (from reading manuals).
Spacious-mind specifiy that RS-1680L has a 6301Y (https://www.spacious-ind.com/html/super_1680l.html) with a 8K ROM.
However, as I wrote it before, its microcontroller (blob) has only 40 pins, the 6301Y has 64 pins and 16K ROM.

The 1680L has 14 levels, plus special levels to checkmate and a "puzzle level" (large win more than 2 pawns), does the enpassant, stalemate,
underpromotion during its search and recognize the draw by immediate threefold repetition : all of this seems to be difficult with only 4K.

So definitly not a 6301V nor 6301Y : I think that RS-1650L and RS-1680L has effectively a 68HC05 with a 8K program.

Cordially.

Thanks a lot for all these valuable pieces of information !

Just another question about the RadioShack Portable 1750L (which I own)...
is it (more or less) identical to RadioShack Portable 1650L ?

Or a little bit stronger ?

Probably with a program written by Julio Kaplan and Craig Barnes ?

Hello Hans-Jürgen

Seems to be a clone of RS-1680L, but it has 64 levels with differents mode (fun, beginners, aggressive,pratical, fixed deep, brute force, passive and normal), and problem level (> 2 pawns).

See https://www.spacious-mind.com/html/portable_1750l.html
and https://www.manualslib.com/manual/13...ack-1750l.html

Cordially.

Neuer ROM dump von Berger: Fidelity CB16 module.

Only 1 byte different when compared to the other dump. I don't know if the other dump is a small bugfix, or that it was a bad dump (changed byte is 0x10 <-> 0x0f, I'm giving more chance to bugfix).

Vielen Dank - Update ist im Anhang (nur neue bzw. geänderte Dateien).

CXG Enterprise S ist emuliert (ist auch Star Chess programm), danke an Sean fur ROM dump.
This is the same HD6301V1 chip that Mychess dumped, but since Sean already planned to do it, I decided to wait for him.

Das sind ja grossartige Neuigkeiten! Sean Riddle ist ein Held! Ich hoffte schon lange auf einen HD6301V1 dump. Mit dem ROM des Yeno 301 XL / Chess King Counter Gambit könnte ich evtl. meine These, dass Franz Morsch dahinter steckt, besser belegen. ;)

Nochmals vielen Dank an alle, Sean Riddle, hap, Mychess, Franz!

PS der Yeno 301 XL verwendet den HD6301X0, mit 192 Bytes RAM, ebenso wie Kittingers Alto / Accord..
