Hi Stifen, if you're still interested, I have the Checker here:
https://www.dropbox.com/s/xviveml5itqrlbf/check4.zip?dl=0I agree that it looks pretty crude (it's from sept. '99, I think) I downloaded it as a possible traffic replacement, but when Econobrick's Checker came out, decided to use that one instead.
Also, an early version of the Eunos Roadster. This one came from the Chistian Pittet archive, so it's not the original zipfile (no readme text, for example). I also think it's an earlier version than the one on that page, because this one doesn't seem to have pop-up lights. Still:

I read somewhere that Zips from the Internet Archive tend to be corrupted because the crawlers used to stop downloading at 1mb. Interestingly, the vidwall archives from Killuncle's still work, probably because they're smaller.
