The new P112 boot disk images are posted - both Floppy and CF module. The floppy image is for use with RAWREAD and RAWWRITE; the CF image is for use with Win232 Disk Imager. The P112 4-Port LAN adapter is ready for shipping.
We're finalizing the software for the P112 4-Port LAN drivers. The Terminal and Printer I/O modules are operating well. The EEPROM burn utility is in final testing. All necessary parts are on hand and ready for shipping.

The P112 4-Port LAN adapter is ready for production. The cost will be determined by the number of PCBs ordered, which will depend on the interest. The Stack180 is still in production and still received the lion's share of our attention. If you're looking for a high performance CP/M system, the Stack180 is it.
P112 kits are coming back on the market soon. We have P112-GIDE PCBs on hand, ready to ship when the P112 kits start shipping.
Stack180 software has undergone major revisions at the system level. Both OS models and the EEPROM code have been modified to support multiple system tracks on each IDE drive. There are now 5 possible boot systems on each drive (Master or Slave) and any one of the five can be booted from the EEPROM. The changes also include a complete re-arrangement of the data passed from the EEPROM to the OS. The OS and EEPROM code work together, so both are required to support the multiple OS boot tracks. Changing the system track offset from 2 tracks to 10 means that all previous IDE and ZIP disks will have to be reloaded. Finally, the partition layout has changed, too, so each partition will have to be reloaded.
A new Stack-180 EEPROM code file is in the download area, Version 2.02.05 of 20 Feb 2012. The major modification was to the EEPROM Load code. Previous versions took approximately 2-3 minutes to burn the EEPROM code. With the 2.02.05 version, a complete EEPROM burn takes about 12 seconds.
A new StackOS image (02-18-12) has been posted, correcting a faulty image from 02-12-12. A New User Manual (02-19-12) is also posted.
A new Stack180 User Manual (9 Feb 2012) is posted. New StackOS and StackBP images also posted.
The H89 D-GIDE has been modified to incorporate a 512K RAM instead of the 128K chip previously described.
A new page has been added to the website - the H89 Page.
A new Stack180 EEPROM file has been uploaded. The new file adds LUN capability to the "L"oader program, meaning that it supports the use of multi-slot Card Readers for reading/creating boot drive partitions from an image file. The "How To" file for XPORT LAN printer configuration is also posted for download.
The StackOS download image now contains the LAN-based printer driver for those machine with the XPORT AR optional component.
The User Manual for the Stack 2MB Memory Expansion has been posted. The RAM Expansion kit is now available for ordering on the Services page.
New StackOS and drive images for B:, D:, and E: drives are posted for download. The latest StackOS contains updated BIOS modules and many improvements to BACKUSB.COM. The 2MB Ram Expansion board now has a 1MB RamDisk driver.
The previous B/P BIOS image had an issue with the terminal redirector data being passed from the EEPROM. As a result, the terminal output would often switch to the 'other' terminal during a B/P BIOS BANK OS load. To the user, this appeared to be a 'lock up' in that no data was being sent to the terminal, nor was the CPU responding to the terminal keyboard. In fact, the CPU was sending/receiving data to/from the 'other' terminal. The bug only manifested itself during the first attempt to load the BANK OS after startup or a hard reset.
