That’s great guys! On addition to this board is now the printer port has a jumper so it can be recognized as both an 16 bit port or as an 8 bit port. This allows you to use the common PC printer ports (278H, 378H and 3BCH) in MSDOS and 78 and BC with a Z80, and yet not have every other xx78 and xxBC show up with an 8086/86K etc.
More “revamped/improved” second editions of past boards coming soon.
I ordered 10 of the S-100 Parallel IO V2 boards. The good news is by doubling the quantity it lowered the per unit (total wrap) to $30 each. They should be here in mid-December or so. Thanks and have a nice day!
Hi! We are getting a small batch of improved S-100 Parallel IO V2 boards.
As you may have seen there are a few very minor board layout errors on out recent S-100 Parallel IO V1 board described here:-
bottom of the page.
John has supplied patches which completely fix the issues. However he would like to have a completely patch free board and is about to order 5 new bare boards. If any current board holders would like to do the same please let me know right away. The cost of these “V2” boards would be somewhere around $40 per board if less than another 5 people want a board.
One small addition that has been made to the V2 board to allow a dynamic 8 and 16 bit port mode of addressing of the PC-PRINTER Port. Other than that this is a “nice to have” item. The current boards once patched are completely functional as they are. It’s mainly an issue of esthetics.
If you want one or more S-100 Parallel IO V2 boards please let me know. The more builders who join in will lower the price for everyone.
