Hm, so perhaps we could derive about 30k ST's and about 17k GT's? That seems a small number.

Well... I guess it explains the reason why there were no successors. It simply was not a successful product.

It’s still hard to judge by just looking at these numbers. If we can compare these with other numbers of Panasonic machines the story becomes more complete.

I’ve logged a lot of Panasonic machines and these are the highest serial per type:
FS-A1 7FAKE72094
FS-A1mk2 8ABMB27565
FS-A1F 8FAKC48487
FS-A1FX 8LAKD15284
FS-A1WX 8LCMC22737
FS-A1WSX 0HNMB29680

The way I look at these the first MSX2 machines sold quite well, there was a new wave of sales when the machines with diskdrives came out. After that the sales steadied (market for MSX basically was saturated and not everyone would ugrade).

I haven't taken the time to really look like it, but those numbers tend to be year/month/week codes, sometimes combined with production facility references.
