Byterapers Grendelparty 1988 was held at a school in Iisalmi, Finland for the C64 and Amiga scenes. Attenders were mostly finnish, the only foreigners in attendence were two Norwegian groups and one American. Attendance was approximately 70-80 people. This was perhaps the first ever party to last a full week. The Cracker Journal report claimed it lasted from the 8th all the way to the 16th, but we choose to trust the information from Byterapers' webpage and Rape 1 (7 april); "our party is going to take place this year 1988 in finland starting 8th of august and ending 14th the same month so its 7 days long and there is coming quite a lot of people". Drinking was not officially allowed inside the party place.
