Laser 350 / 500 / 700 / 750

laser50

Technically the Laser 350 / 500 / 700 / 750 are completely different from the Laser 100 / 200 / 300 family and thus non compatible with them.

All 4 computers are nearly identical but the Laser 350 use a Laser 300 case while the Laser 500 / 700 / 750 use a "new" case.

Though the CPU is still a Z80A compatible one (the D780c from NEC), its possibilities are better.

There are now 6 graphical modes, ranging from 160 x 96 in 16 colors to 640 x 192 in 2 colors. The memory size is also better compared to the old serie and goes from 16k RAM for the Laser 350, to 128k RAM for the Laser 750. The Laser 500 and 700 have 64k.

Due to its "low" memory size, the Laser 350 cannot use the GR3, GR4 and GR5 graphic modes, unless it is upgraded with a 64k or 128k RAM expansion....

The 64k RAM expansion can be used with the Laser 350 to upgrade the memory to 64k or with a Laser 500 and 700 to upgrade their RAM to 128k.

In the same way, the 128k RAM expansion can be used with a Laser 350 to have a 128k RAM Laser 350 !

The Laser 700 and 750 have a centronic port built-in while it's only an option for the Laser 350 and 500. They also have two disk drive ports taking the place of the memory expansion port, the disk drive controller being built-in. And finally, the power supply is also built-in the Laser 700 / 750.

When you open up a Laser 500, you find a small mother board taking hardly a third of the whole space ! It's clearly a mother board that could fit in a Laser 300 case, and that's what they've done with the Laser 350. Thus we can say that the Laser 500 is only a Laser 350 with more memory and a different case. The real improvements are in the Laser 700/750.

Ok, let's sum up all these infos !
