The HP part numbers for these masked ROM devices should be 1820-2437 and 1820-2438, respectively. I'm asking because I'm working on the MAME emulation of HP85 and I'm about to begin implementing these modules (especially the 1st, so that HP9895 disk drive can be interfaced). Thank you very much. -- F.Ulivi
