A hardware shifter would be quicker but would also require a lot more logic chips.

The whole idea is to keep the hardware as simple as possible so that anyone can build it.

NP, from my perspective anything starting by 74 immediately trigger TTL.
Fair approach but probably everyone capable to order PCB (as probably nobody nowadays doing PCB by himself) and solder all elements and make board run is capable to solder even 3 more IC's.
Guys who prefer to buy assembled and working PCB probably don't care about 3$ more... And i have strong impression that 150KBps vs 500KBps is something worth such complication.
Anyway it was just quick idea.
Thank you for all work! Appreciate it very much.
