Yes me too. The majority of spanish MSX1 not have the ñ key. The Toshiba HX-10E was aimed at the Spanish market but the Keyboard doesn't have ñ key, same for the Goldstar FC-200, Spectravideo SVI-728.

I think it's better to avoid putting (HL), (DE), ect to explain how the z80 works in "Assembler for Dummies (Z80)". It's shorter to explain but it's may repulsive for beginners who do not yet master this notion.

MsxHolder added the remarks:

Quote:

The PCB shown in the picture is not from the HBM-512: it’s a clone for a Philips case!
As you can see in the service manual the foto of the pcb is not of the sony hbm-512

(The second sentence was removed by someone else last december without any justification.)

If I look at the service manual, MsxHolder seems to be correct, the service manual’s print has the ICs oriented sideways rather than upright. Also it does not show empty spots for four additional memory chips, which also puts into question the remark that:

Quote:

This cartridge is intended to be expandable to 1024 kB.

Looking at Bas-Ditta’s upgrade guide, it says to piggy-back the RAM chips, further suggesting that the PCB image is not correct.

Quote:

Soldeer de 4 geheugenchips (44C256) met de ingekorte pinnen op de 4 al aanwezige geheugenchips. Afhankelijk van de cartridge-behuizing komen deze aan onder- of bovenzijde van de printplaat

Also generally speaking looking at the complexity of this upgrade, it seems not at all intended to be expandable.

If anyone who owns an HBM-512 could confirm this (), I would suggest to remove the PCB image from the article, and to remove both the phrases “This cartridge is intended to be expandable to 1024 kB.” and “The PCB shown in the picture is not from the HBM-512: it’s a clone for a Philips case!” as well.

I put again the image since it seems definitely lost.
