"The speed-up manual states that the Arch bold speed-up is the best... the manual doesn't lie."

Well, when you speed up the operation you shorten the debounce delay. As a result, I have noticed an occasional keybounce. At my speed-up rate it is not bad, and cleaning the keys seems to have eliminated it altogether. I do see a problem for those who jump up to six MHz, because the delay will be so short as to be totally ineffectual. If you know your debounce program you can increase the delay and solve the problem. If not, you will be stuck! With no debounce and the high speed mod it is likely that the key bounce problem will be magnified. (My experience and testing verifies this.)

There is a bright side to this point that might interest users of Level II with the new ROM based debounce. I have heard complaints that this built-in debounce is too slow, and fast typists can easily outrun it. In that case the high speed will probably make the ROM based debounce a little easier to deal with.

Unexpected Goodies

I have a disk system and I very seldom use my cassette at all. There are, however, a few games and applications programs that are not disk compatible, so occasionally I run the cassette. After installing the Arch-bold kit, I wanted to see how it affected an Invaders game. Well, the game ran super fast and posed a real challenge, but I noticed something strange. The cassette loaded the first time with no error. That surprised me because that particular cassette usually took several attempts to load. In fact, I thought that there was a problem with the first program copy on that cassette because it always gave me a checksum error. I usually had to load the second copy and often that didn't work either.

This bit of good fortune started me thinking, so I pulled out some other difficult to load cassettes in both BASIC and System. They all loaded the first time! I won't guarantee that the same will happen in your case, but I suspect that when the speed-up kit is in the normal mode it actually runs a bit slower than the original set-up. For that reason the data transfer is less likely to miss bits and less checksum errors will occur. I may be off base with this conclusion, but I can say that all my cassettes load. Even ones that I had given up for dead now load fine. Also I have noted that BASIC and System tapes load at the same volume.

Conclusion

The speed-up manual states that the Archbold speed-up is the best available regardless of price. I haven't tried any of the others but I know people who have. Based on what they have said, the manual doesn't lie. I'm very satisfied with the increase speed of operation, and even though the installation was a bit tricky, it was well worth it. If you would like that extra speed, then buy Archbold—it works and it works right!!

Note: In all fairness to Archbold Electronics I should point out that I ordered my kit from an old advertisement. The March Issue of 80 Micro has a new ad which is more accurate and points out the Z-80A and B options. Also, the price is now up to $45.00.
